bartonmd Posted December 21, 2005 Share Posted December 21, 2005 You have to look at the SAE seal on the oil. Friction modified oils WILL fuck your clutch in a wet clutch system. You need to stay away from the energy conserving oils. Trust me I've been there. 1999 Katana, 3000 miles, second oil change, went to an energy conserving synthetic (didn't know better, bought whatever was on sale). Clutch immediately started slipping at anything over 3/4 throttle, and had to replace the plates because it continued to slip even after two changes back to striaght Suzuki dyno. Luckily the clutch in a bike is nothing like the clutch in a car, as far as labor. Look at this link, the "ENERGY CONSERVING" wording in the bottom of the SAE circle is what you want to stay away form. http://api-ep.api.org/filelibrary/API_MotorOilGuide_2004.pdf I've seen what you're talking about on other bikes, but I've never seen it on the XX... I'm sure it's happened, but I've not heard of it... It'd be my guess that the XX is just over-clutched, so unless you're drag racing and stuff, especially with power adders, you won't notice anything... but I still stick with oils that aren't energy conserving...

sykotek-xx Posted December 21, 2005 Share Posted December 21, 2005 Might be, I was running a stock clutch on the katana but had it worked up nice, stage 3 jet kit, individual cone filters, full stainless yoshi 4>1 race pipe, sprockets, probably why it ended up planted in a guardrail with my dumb ass sliding along behind it. So it may be that the XX has better clutching, stiffer springs. I think that the newer bikes lost a couple clutch plates vs. the old ones so maybe the newer ones wouldn't be as lucky as the older ones. Like I said I had it happen, first hand. Perfectly running bike with virtually no miles, went to synthetic, and it ate the clutch. Never raced just ridden hard. Quote Link to comment Share on other sites More sharing options...
Keith Posted December 21, 2005 Share Posted December 21, 2005 I know you cant mix mineral and synthetic oil directly. How do you know this, and what would happen if you did? Aren't sythetic blends a mixture of mineral and synthetic oil? I believe so. If manufacturers mix them in their own bottles, I guess we can mix them a little in the bike...

bwflorence Posted December 21, 2005 Author Share Posted December 21, 2005 Thanks guys...thats some good info there. ...and dont worry...the engine is fine. maybe ill just do a standard oil change after all.... Quote Link to comment Share on other sites More sharing options...
blackhawkxx Posted December 21, 2005 Share Posted December 21, 2005 I have heard that new corvetts come from the factory with Mobil 1 in them. So, maybe the slick oil don't harm brake in. Quote Link to comment Share on other sites More sharing options...
sykotek-xx Posted December 22, 2005 Share Posted December 22, 2005 that is true about the vettes. Maybe they're broken in at the factory? who the hell knows. Quote Link to comment Share on other sites More sharing options...
bonox Posted December 22, 2005 Share Posted December 22, 2005 ps, if you do decide you ever need to flush an engine, there are special very light weight oils for that purpose, that mix with the original oil (but do not act like solvents as petrol/diesel will) and come with large printed words about idling on a hot engine for short time only. ps, never felt a need to do an indepth flush on anything - i figure the older it is, the worse a flush becomes if you try to clear the deposits that are actually holding the thing together. The engine oils these days tend to come out all nice and runny when hot as well, and when dropping the pan, they seem to clear the solids as well.

OZDave Posted December 22, 2005 Share Posted December 22, 2005 I understand.Thanks for the advise. Damn, you handled that well. I'm impressed. Everyone else that received some constructive criticism of that nature usually has a big sook, abuses everyone and leaves. I wish I was that mature.

Very true... and if you do a little more digging you will find that most of your Synthetic Motor oils are made from Base Mineral Oil. The only one that I know of right of hand that is Truely 100% Synthetic is Amsoil. Quote Link to comment Share on other sites More sharing options...
arcticflipper Posted December 22, 2005 Share Posted December 22, 2005 Would like to apologize to everyone esp. bwflorence if anything I said on here created the wrong impression or disgraced the forum in any way. Quote Link to comment Share on other sites More sharing options...
bartonmd Posted December 22, 2005 Share Posted December 22, 2005 EVL, I believe Mobil 1 is also a 100% synthetic oil, but those 2 are the only ones I know of other than the REALLY expensive stuff... Arcticflipper, I agree, thank you. I wasn't trying to be a dick or anything, although it may have come off like that, but I've seen stuff like that happen before (mostly on car forums to tell you the truth) and just kindof wanted to show you what could have been done with the info in what you posted...

vetteman Posted December 22, 2005 Share Posted December 22, 2005 I have heard that new corvetts come from the factory with Mobil 1 in them. Â So, maybe the slick oil don't harm brake in. along with porsches, some beemers, vipers - i think, and many others. no break in problems.

bartonmd Posted December 23, 2005 Share Posted December 23, 2005 Yes, vettes and others have been running synthetic for the past few years right out of the factory, but I will say one thing... A lot of the engines that I know of that run synthetic brand new are engines that are considered relitively low volume, high quality mills... Due to this, I believe they probably have less breaking in to do because of higher quality parts and tolerances kept closer to nominal... The only engines I've seen take a long time to seat rings and stuff have been high volume stuff that probably doesn't have the QC that the higher end stuff has... Just something to think about...

Guest rockmeupto125 Posted December 23, 2005 Share Posted December 23, 2005 I'd venture to think that a high performance Honda engine has at least the same qc as a Corvette engine. Personally, if I ever got a new bike, I'd probably change out the delivery oil to synthetic on the first change, or no later than the second...and only because I change oil twice on a new engine....once at the 50-100 mark, and then again around the 1000 mark....and I'm a cheap so and so.

bartonmd Posted December 23, 2005 Share Posted December 23, 2005 I'd venture to think that your venture to think was correct... Mike Quote Link to comment Share on other sites More sharing options...
HERBXX Posted December 24, 2005 Share Posted December 24, 2005 I did my first oil change at 800km and switched to synthetic. In correspondence with Castrol, the nice tech lady stated the break in would still continue with the synthetic(if needed) only at a slower rate.
