Which 2 - Cycle Racing Oil is Best?

[YZ250]

You see all these ads in magazines and on T.V. about racing oils, but the true question still remains: Which brand is best? There's Bel Ray, Ams Oil Dominator, Lucas Oil, etc. The only problem is that if I want maximum performance out of my bike which oil should I get? And if mixing the oil at a certain ratio (Between 50:1 and 32:1) makes a difference, than what would be better? It probably matters what bike you have but 2 stroke race bikes are still 2 strokes and lot's of the mini's use recycled technology from the big bikes. So in a sense they are all similar, so there has to be one kind of oil that is the overall best for 2 stroke bikes. Just which one to choose...?

There was a thread awhile back about oils.
You can go on for ever about which is best.
Just buy the best you can afford and jet the bike to suit.
And stick with it.

Yep, what the Kiwi said. Some oils are insanely priced and i dont think are any better than something that may be $5-10 cheaper.

We used to run spectro sx way back when but have been running super m for a few years at 32:1 and had no problems at all.

I have been running YamahaLube 2R at 32:1 for a few years and really like it. The only bike I have had any issues with is my nephew's CR80. But that bike was jetted insanely rich. I dropped the pilot two sizes and raised the clip up a notch and it stopped fouling plugs but it still gets "spooge" out of the exhaust tip.

Over the past winter I had Max Power do a big bore on my Honda. To my suprise they recomend Yamalube as well.Also they recomended 32:1.stating oil is cheap engine parts are not. I also agree pick a flavor jet for it and stick with it. I switch oil once on an old Kawasaki I had and it refused to run right.

is it ok to mix brands of premix?  and syntho with dino?  i ask because there have been times ive run out of one brand, and have mixed it with another......
i know its not a great idea, but is it bad to do?

[TMKIWI]

Not a good idea to mix different types of oils.
Synthetic and mineral oils dont mix well together.
If you are in the middle of no where and have no choice it wont kill the bike , But its not a good idea.

YZ250 Assuming you are asking about pre-mix for a YZ-250 I would use Yamalube premix or whatever your bike manual recommends,which is probably yamalube.However in the past I've had good luck with Golden Spectro and Maxima but now since I own a KTM and my manual recommends Motorex at a 60 to 1 ratio thats what I use,but I actually mix it 50 to 1 because to me 60 to 1 is too lean.
