I change oil every 2-3k regardless of what I'm using.  I agree with Paladin on the oil filter life as well.

Did run into a funny issue running amsoil that really makes zero sense but I'll post it anyway.  Last summer in Minnesota (not overly hot) I ran amsoil.  I've used amsoil for years with good results.  Put it in the raider and immediately noticed that I'm running hotter (yep, makes no sense).  Grabbed my little RC infared thermometer and started taking it along for rides doing temp checks at stops.  I was consistently running 20 degrees hotter than I usually did.  After the summer was over and I changed back to yamalube temps went back down for this past summer.

Not sure what I'll put in her next...gotta change oil soon though.
;D ;D Now that your in La its prob gonna run a tad warmer. Not quite as cool as up north i suppose.

...water cooled engines, which have tighter tolerances than air cooled engines. Because air cooled engines operate at higher temperatures, they have greater expansion rates than that of water cooled engines, so their tolerances have to be greater, which will cause more combustion residue to by pass the piston rings and contaminate the oil at a faster rate. I'm also basing my opinion on the number of engines I've rebuilt over the years...

As far as combustion residue, isn't it very related to the number of heat up and cool down cycles?  Long trips require less oil changes and short hops require more.

I think I'll cut open my Raider filter at 4,000 miles and my Honda CRV filter at about 10,500 miles and see how much residue is on the media.  Not sure what to expect.  When I do, I'll try to remember to post back here.  Won't be soon though.

Yep.  I might be forced to switch back to Amsoil due to the heat.  I'll probably run one more cycle with yamalube this winter and then switch to Amsoil again in the summer.  Hopefully I don't have the same amsoil problem before.  Odd cause synthetic should reduce heat, at least from everything I've read.

Its funny I've never had issues with it before.  Although it did cause my wife's xs650 clutch to slip some.
I wonder If I just got a bad batch of it in my raider.

Castrol sells a 10w50 synthetic MC.  Looks like the newer owners manuals say 10w50 is ok.  I've emailed Castrol asking if the useful life is the same as their 20w50 and no reply yet.

Synthetic oil does not decompose from heat until ~900 degrees F. 

900 degrees? Where did you get that figure?

A typical combustion ring in gas engines reach about 300 degrees, and the top rings in diesels can approach 600 degrees.
Dino oil will typically begin to oxidize beyond use at around 550 degrees and full PAO synthetic will go to a little more than 700.

at 900 degrees any PCO will have long been useless.

But...if you have an engine running 900 degrees internally, you may have other issues to think about :)

When I worked in a refinery one of the scientists told me that approximate temperature of 900 F. with respect to full synthetic oil.  From IR guns our Raiders run around 275 to 325 F on hot days.  No way the Raiders run any where close to 900 F.  The lack of "impurities" from mother nature and chemical stabilizers make the full synthetic oil more heat stable.  The full synthetic also maintains its lubricity much better than regular oil.

some one wrote in about amsoil this and that. i noticed he didn't have a comment about the shear rating on amsoil as compared to ALL other synthitic oils. no comment? my motor is worth the extra $$$ for the oil that doesn't crap out before the other syn oils. this is not opinion. this is based on an actual testing. what are you reading that states otherwise? don"t talk, just show me the facts. big john

Update on what Castrol told me.  In so many words they said the "service" life of the 10w50syn vs their 20w50syn will meet the oil change intervals Yamaha specified and to follow manufacturer recommendations.  So, in my words, they didn't provide the answer I was looking for, but did provide the answer to be expected.

+2 (thanks to this thread I just read more than I wanted to on Amsoil vs. Mobil 1, I will stick with Amsoil)

The only way to determine if you're oil is okay to continue using is to get the engine good and hot.  Then with the bike in a level position, remove the dip stick, wipe clean and place back in. Do not screw in.  Then remove the dipstick and place directly against tongue.  If it has a fishy taste it's no longer good and should be changed immediately.  If it tasts like chocolate chip cookies, then it's okay to continue using.

Oh and if anyone actually attempts this, PLEASE post it here.  I could use a good laugh.

Is this procedure for Synthetic, or Dino?
