I know theres probably a ton of threads on this, but I want to know what the best full-synthetic oils are for my 09 YZ.
I feel like I should be running something better than what Ive been using (Yamalube 10-50 semi). Already have a scotts filter too.

There are a good many excellent full synthetics available that will legitimately outperform oils not specifically blended to lube BOTH engines and transmissions. My favorites are Amsoil 10w-40 Synthetic Motorcycle Oil (ID# MCF), which is actually labeled for gear lube uses at API GL1, and Mobil1 Racing 4T Motorcycle oil. Each of these has an equivalent 20w-50 product (Amsoil MCV and Mobil1 V-Twin) that can be used in really hot weather when an 50 weight is actually called for.

There is less difference in the ability of most major synthetics to adequately lube an engine than in their ability to both lube a transmission and to survive in that service for any length of time.

Went from yamalube to silkolene to amsoil mcf. Amsoil was a noticeable dif. in how smooth it shifted. I'm stayin with Amsoil.

Once you do your research on what is actually in oils, Redline is really hard to beat.

Spectro 4 (syn/petro blend) and Platinum 4 have shown very good results in lab tests.

I should mention two kinds of oils to avoid:
  • Any oil marked API ECII (level two energy conserving. most likely will not see this in any motorcycle oil)
  • Any oil marked JASO MB (these are friction modified oils for engines only, and not for use with wet clutches)

I just switched over to Amsoil 10w40 from the standard Yamalube oil and I had to turn my idle down because it was revving a little high. Kinda wired.

I use motorex cross power 4t 10w - 50 since I got it for almost free. When my supply runs out, I'm back to amsoil. My bikes like it better.

For Amsoil, is it their 'advanced synthetic motorcycle' oil that people are using?

Here's a third for Maxima. Through my club we got a tour and lengthy Q and A session at Maxima. I was a fan before and the depth of knowledge and impressive number of performance sports awards there back up all their advertising claims.

My personal experience has also been excellent whenever I use Maxima.

What group of oil is it?

Extra is a Syn/Petro blend using esters. Ultra4 is a Group IV/V (PAO/Ester) blended base oil, while everything higher than that in the Maxima line is a Group V. There are more important aspects, IMO.

Here's what I don't understand about this comment. Redline uses the best oil base stock known to man currently and typically uses a higher percentage of additives than anyone else. It's a win win in my book. I have years and years of practical experience with Redline oils and can't b happier on the reliability and longevity. I'm not saying that other oils won't give good results. I just like to go with a proven top quality oil. Why take a chance?
