Rotella T

Make sure it's the Rotella 2T for 2 strokes.

I use it in my YZ250 and I've used it in my son's 04' CRF250 for 8 years (a notorious valve eater) with no issues. Do a search here or Thumpertalk for more info/commentary on this issue than you could digest in a lifetime.

I use it in the trans of both of my YZ250's and my Dodge Cummins with 500,000 mile on the clock. My brother runs it in his '11 YZ450f as well. We haven't had any problems what so ever. Great oil IMO.

i run it in every bike i build with every bit of confidence i have. its one badass oil. search TT for more scientific write ups

I use it in my tractor, generators, motor home and all bikes and have for several years. It is great stuff at a very good price.
I switched to it from Mobile 1 I had used for years, but the price started getting out of hand.

Time to do the oil change on my Toyota 22re and I'm going to use it.

In my bikes I prefer a better motorcycle rated oil. That's just me. I don't like the use of pulling drain bolts so often. I can go 10-12 hours before the Motul300v shows degradation. It's too easy to strip threads on those the small bolts on a Honda.

Rotella T6 5 W 40 is a motorcycle rating oil put out by the bike manufactors. It shows the same rating and is designed to replace the 10 w 40 used in a lot of bikes and is wet clutch rated.

Big fan of the motul300v - but I stopped and went to rotella. It's good stuff.
