The dreaded oil thread for a new owner

Yes, I know the oil thread is back, but I really need to know what the group reccomends. I have a manual that says 20-40 SE but what do the sensei's of the group say. I live in N. Florida, summer is coming and I mainly commute or just putz around. I already have two weights for the BMW airheads and the XS650, so go ahead and tell me I will need a third for the 82 650 Seca, I can take it. I'm using dino in the others and don't really trust synthetics in older bikes, but I'm willing to listen to the opinons. While I'm at it, any real world reccomendations on sparkplugs?
I gotta do some work on the Seca this week and would really like to get it right the first time.

You really are looking for some hurt. You might want to do a search on type of oil etc on this site. There are many previous posts and each have their favourites.

I use 10-40 Mobil 1 synthetic for motorcycles. Up here its called MXT or something like that. If you go to Mobil's site you can read all about it. I've tried just about everything but find any of the 15-40 or 20-50 weight stuff that some use just causes too much clutch and starting drag. I find that the motor noise is louder with the heavier oil. Much quieter and shifts better with the synthetic. Maybe its our climate. I do recommend Motorcycle specific oil that has the JASO-MA spec. Up here many oils including Castrol Grand Prix Motorcycle oil 10-40 or 20-50 aren't labelled with the JASO-MA spec. Go figure.

As to plugs NGK either the BP7es or Iridium ones. I use the Iridium ones.

Welcome and there is lots of good info on this site.

 

I'm near Orlando and I would never run a 30 weight. Any name brand oil that is not an "energy efficient or friction modifier" oil will meet the requirements, this is due to the fact that we run a wet clutch, but it's good to go the extra step at least, and get a "diesel certified " oil, such as Rotella - T from Wal-Mart. Or a racing oil (DINO) such as castrol 20w50, And your top shelf oil is motorcycle specific Ams-Oil or other quality synthetics, if you can afford them.

What bad experience have you had with synthetics?

Don't use resistor plugs- - I've heard.

 

Lets see if we can all sing the Chorus to this song:

Synths are no good for the Clutches.

Castrol 20W/50 meets or exceeds ALL requirements for a high revving inline four cylinder motorcycle with a wet clutch.

If you put synthetic in it and have Clutch trouble ... remember ... we told you NOT too!

So, don't do it.

Put 20W/50 in it and sleep well at night.

 

Sorry, but based on my experience with synthetic oils in everything from singles, V-Twins, and in-line fours, I disagree.

I've never had any clutch slipping with a synthetic oil, even while riding my R6 hard. With 110 hp and shifts at 11,000+ rpm, the clutch has never slipped.

I use Mobil 1 Racing 4T 10w-40 in both bikes.

NGK plugs - regular on the Seca and Iridiums on the R6 because it's a three hour job to change plugs on that bike.

 

I have been using 20/50 and had no problems but its was due an oil and filter change and i have just been given a 4l bottle of Shell VSX 10/40 synthetic motorcycle oil. Clutch seems ok, engine seems slightly more responsive and it holds a low idle a lot better. I have only done about 70 miles with this oil in and so far had no problems, if i have any problems oil related i will report it back and take the beating but so far very happy with it.

 

Oh, this ugly can of worms...
"Can't we all just get along?"
Jury is still debating this one.
I've not used synthetics...yet. Not particularly inclined to do so yet either. Had a fellow on the forums last week with a clutch problem and it cleared up when he drained the fresh synth and used dino oil. Go figure. If you can run synthetic without problems, by all means. Just don't bother complaining later. This does not mean don't tell anyone, we still want to get the feedback on your experiences.
Terry, I'm in southern California and I run Castrol 20/50 without problems. Weather here is warm enough to warrant the weight and for your temps right now you should be just fine. Drop to a lighter weight in the cooler weather. Avoid any oil with an API "energy conserving" rating on it. Those guidelines should help you make a good selection, dino or synth.

 

Thanks for the information, it's very helpful. But when you say Castrol 20/50 do you mean the "GTX" car oil or the motorcycles specific Castroil. As for the syn oil, The BMW airhead seals will weap like a an old Harley, and the XS650 had a hard life before I got it so I think it might do the same. I do use syn oil in my car and truck though.

"Just don't bother complaining later." IMO that sounds a bit condesending.

The jury is not still out on this, synthetics are fine.

Do you think Yamaha would put their name on a synthetic oil and reconmmend it for their motorcycles, if it would cause problems?

http://www.yamaha-motor.com/sport/appar ... etail.aspx

Sounds to me like some on here are just parroting what they've heard without any real experience using synthetic oils.

Bottom-line, if you use the wrong oil (energy-conserving) whether dino or synthetic, you may get clutch slippage.

 

most oils that say synthetic are just basically highly refined dino oil
to throw anouther monkey wrench in the mix the only oil I ever used that caused my clutch to slip was castrol 20-50 do i think its a bad oil because of that NO!!! I think that paticuler bike clutch didnt like that oil,I switched back to the valvaline oil that PO had always used asap and problem solved...
I think opinions are great but realy hate seeing opinions stated as facts it can get confusing and I am seeing more and more of that on this forum..

 

Come-on!
That's crazy.
There's NOBODY going to buy-in to Castrol 20W/50 causing a Clutch to slip.

Castrol 20W/50 is simply the best Racing Oil that money can buy.
You use it because you trust it's superior to other Multi-Grades in that if offers the best protection at high revs and high heat.

20W/50 is formulated to prevent Clutch slippage.

Castrol GTX is one of the world’s most trusted motor oils. It’s more than just oil. It’s liquid engineering that protects against problems, like high and low temperature wear, your engine faces every day. Why is this protection important? Because high temperature can increase stress in your oil and at low temperature some oils are not working fully. Either can reduce the ability of ordinary oils to protect against engine wear.

Castrol GTX provides superior protection for your engine:

* 50% better high and low temperature wear protection

* Superior protection against sludge build-up

* Superior protection against viscosity and thermal breakdown

* Made from premium quality base oils

* Keeps engines cool and clean

* Formulated for Motor Racing and Motorcycles with Wet-type Clutches

 

The XJ god has spoke all other opinions are now null and void!!!!!!

Bye Bye XJ forum I'm outa here

 

Rick your starting to sound like an advert

 

Why not? Apparently you've bought into the myth that synthetics cause clutch slippage.

In his experience he had an issue with Castrol. Why is that crazy?

We've all had a bad experience with something that others think is the best. He was just relaying his experience. There's no reason to beat him up about it.

 

You know, I wish someone would put a car tire on their XJ.

Over in the ventureriders.org they argue about whether using one will result in fiery death or freedom from the vultures that sell overpriced MC tires that wear out too fast.

I'm pretty tired of the oil wars.

 

I have not been part of a good oil thread in a long time!

*Spinalator eases back into the chair with popcorn and watches this thread with interest*

 

What do we have to do ... take a Poll of Castrol 20W/50 users and ask them all if their Clutches ever slipped using the product.

I don't think so.

I KNOW it don't cause Clutches to slip. Just like I know a lot of things I see get typed into the Forum's are wrong or bad advice.
I try to be a voice of reason.
I will never lead anyone astray.

There are a few that offer words of descent no matter what the topic is about.
Every now and then, somebody gets outraged and tries to right the ship.

Based on nearly 30 Years of experience running Castrol 20W/50 in a long list of different Makes and Models ... I never once had a Oil related issue with Castrol 20~50.

I also reserve the right to be beyond skeptical of claims that anyone has after I just finish recommending it to newcomers to the Forum.

I know the score.
I keep score.
There are a few who lie in wait to disagree with and tell me I'm full of it.
Too bad they haven't anything better to do.

 

Rick,

Your condecending "don't bother to complain" if you use a synthetic sure didn't sound like the voice of reason to me. It comes across as "use Castrol or else."

I KNOW synthetics don't cause clutch slippage. Just like you, it's based on decades of experience using them. Saying that synthetics cause clutch problems is "wrong and bad advice" and based on heresay.

Someone may have problems with Castrol and someone with synthetics, but in both cases those instances will be few and far between. It's just the randomness of life.

You're obviously a member of the Cult of Castrol. That's fine, but don't poop on others for wanting to try something else or having a negative experience with something you've recommended.

Also, you're not the only one around here with years of experience. There's a lot to learn from everyone on here.

 

You have a very good point there Jim. Yamaha should be the last word on what to put in the machines they engineer. I've nothing against using synthetics beyond price (and even that is getting less and less of an excuse).

You got me there, bad choice of words.

I do believe I qualified my position, thus no parroting is involved (at least not on my part). My synthetic education may be out of date. When I visited this issue, it was back in the early 90's and synthetics were an exotic option best left to the rich guy. From what I have heard and read (I'm not inclined to remain ignorant on topics of interest), synthetics have gotten much better and far more reliable than 20 years ago. Several of our members have passed along their positive experiences, a few negative. Coupled with research and feedback, I would not call making reference to these reports parroting. To each his own I guess.

Upon this we all would agree.
I think we all have our ideas of what the "right" oil is and the truth, IMHO, is that there is more than one answer to this question. My feeling is that we are all trying to give Terry our best opinions (however some of us are not doing a good job of it, my apologies).

Terry, I have used the GTX oil with no problems for the last 15 years.

And Rick, I'm with Acergremlin, you sound like an advert.

 

I'm not worried about the guy who has been operating his bike wiath whatever he puts in it for months on end without so much as a hiccup of trouble.

But, when as NewBee checks-in and hears that running a Synthetic is cool ... He's liable to go out and spend some extra dough getting a Synth that's NOT rated for use in a Wet Clutch Bike.

Too easy to do!
You cannot depend on the auto parts clerk to be fully knowledgeable of what you bike requires regarding its motor oil.

So, instead of advising the New Member to go spend money on a synthetic he does not need and should not use ... it is infinitely easier for me to recommend what I know IS good and WON'T cause a problem.

 

Rick,

Sorry about the "parroting" comment. It was a bad choice of words.

Twenty years ago, I used Castrol GTX exclusively in my '68 Camaro Z28 and probably still would if I still owned that car (I wish I still did. I sold it for $6K then and it would be worth close to $40K today).

Now when the heck is Spinalator gonna start sharing his popcorn?

 

This sounds a lot like a bunch of guys sitting around arguing about which brand of beer is better. One good thing about the web you at least can't here the shouting or nashing of teeth.

Brand type or dino/sync doesn't matter. A lot of it is marketing hype.

What does is it designed for use in a wet clutch equipped motorcycle. As long as it meets the JASO motorcycle standards and the weight range falls in line with what the manufacture recommends that's all that needs to be said.

All I'm going to say is that you really have to treat you and your bike to a modern good brand of true motorcycle synthetic motor oil. The whole bike works better with guieter startups, easier shifting, gains in idle speed ( you have to slow it down slightly), a few more miles per hour at a given RPM and so on. It is amazing stuff.

Maybe we all should lighten up and not take ourselves to seriously. If we all did exactly the same thing it would be a pretty boring place.

 

If you think this thread is interesting, just wait until we get started on the "mine's bigger" thread.

 

BINGO!

FOUL! The gear ratio is the same no matter what oil you put in.

 

My concern is that the Synthetic boast of being to be able to provide protection well beyond what we'd consider a routine oil change interval.

Take my '04 Chevy Monte Carlo for example.
Chevy recommends Mobil-1 Synthetic Oil 5W/30.
Chevy says that Mobil-1 in the Monte will outlast any other Oil and doesn't need to be changed until the Oil Life Monitor flashes on and indicates the current fill has has had it.

Depending upon how you drive that interval might extend to over a year on the same Oil.
Despite the claim of not needing to change the Synthetic ... I change it at
5 or 6-thousand mile increments and reset the Monitor.

We should be advising the Membership to CHANGE their oil in the bikeks not run it longer.
The engines work hard and some "Use" if they are aged, which all are in calendar years, but some not so in terms of mileage.

My thoughts are to advise the Member making an inquiry about what Oil to use to do the best thing for his ride.
That's why I recommended the Oil I do.

Recommending something other than what I know is good protection and best for the clutches is why I indicated the brand and viscosity I have always mentioned.

I'm not a stockholder of Castrol.
Not their pitchman, either.
Just a satisfied customer and have been for a long, long time.

When I had my MGB ... all I ran was Quaker State 10/40 in it.
I drove that MGB nearly 300,000 miles on it with only two rebuilds in its lifetime.
Those were the fun days!

 

Ammo for the next salvo!

I had this linked from about 5 or 6 years ago, and it may be out of date, but I (and my inner troll) will post this for your consumption, and look forward to your comments and stuff. This has not been updated since 2002 and was on a VFR site. The author is a retired oil chemist and motorcyclist. http://www.vfrworld.com/tex_vfr/tech/oil.htm

 

being a newbie myself, when I went looking for oil I went with Yamalube. It was recommended by some friends and by a couple of mechanics. I also figured, hey my bikes a yamaha and this stuff is made by yamaha for their bikes, It may be a little more expensive but hey, my life depends on the bike so I was willing to fork over a little more. Thanks for the thread I enjoyed reading it.

 

Don't go to the Dealer for your Motor Oil.
Yamaha isn't in the Oil Business.

It's just the same oil you get in a Container without the packaging that allows the Dealer to charge you more for what you'd get if you bought it elsewhere in a bottle NOT having the Yamaha Brand affixed to the package.

 

Excellent article. Thanks for posting it.

My Venture gets the WalMart SuperTech 2000 15w40. I'll probably use that in the XJ when the fall weather comes.

FWIW I have two SUVs with over 150K miles. They always get the SuperTech oil. The car also gets SuperTech oil, but it only has 130K :lol: . I've never had an oil related problem.

Ok great XJGOD I am sure this is directed at me,I take this ands your other post calling me a liar in your sneaky roundabout way as a personal attack!!!!I am also sure it is ok since you are a moderater!!!!
Just for the record I have sent 2 emails asking to have my account deleated hopefully it will be soon,but since it hasnt yet I am going to speak my mind..
Ol buddy Rick you need to crawl down off your high horse,if you are as great a mechanic as you say you are you will know sometimes crap happens,no reason no explanation crap just happens..I also challenge you or anyone else to go throgh all my posts and show where I am trying to rock the boat,I have had a differant idea or opinion then ol buddy rick a time or two but I guess I was wrong thinking this was a place to share,not worship the great XJGOD..
No where did I say castroil was a bad oil,I said I had a problem with it once,I actually like thier oil and use it,nowhere did I recomend synthetic oil I made a factual but aparently not so well known fact about it!!!!!!!
So sorry I hurt you your feelings super XJ master Rick!!!!!!

I also PM'd super Rick but it apears rather then talk in PM's he would rather take anouther shot at me in the forum real classy ol buddy you are definatly showing me your true colors!!!!

Robert,Woot you are both class acts so would one of you please deleat my account!!!I dont want anything to do with a forum where the moderater is a instagator then tries to act like the member is out of line!!!!!

 

Oil Threads never fail to disappoint.

Old Grunt, take some happy juice and a week off from the forum and all will be well. I suggest 18 year old scotch, but after spending a year in Ireland, I have grown fond of some of the Irish stuff as well.

You can leave if you want to, but no need to go away all angry and stuff. Geez,you are forgetting about rule number 1 in Internet Forums: Have a thick skin and don't assume everyone is an asshole, just because they type that way.

 

Is the Castrol 20w50 made for motorcycles specifically or for automobiles? Thanks for the info.
