I'm far from the only one using Rotella T6 with no issues on this forum.

I believe it meets or exceeds LL01 spec at least, but don't quote me. My engine is markedly quieter, smoother, drinks little to no oil, and I use it year round. If it can keep dirty Diesel engines clean I'm sure that's nothing for this oil on our gas engines.

For what it's worth I also use it in my Triumph Thunderbird as it does have the additives needed for wet clutch packs, talk about versatile. Apparently T6 is very shear resistant as well, M1 0-40 is known to shear down to 30 weight fairly quickly.

All I know is my M54 drank a quart of M1 0w-40 every 1500 miles, now it's more like a quart every 3-4k with T6.

Give it a try, I've recommended it to several members on the forum and they report good results. At the price it's unbeatable, I was using castrol and M1 at 7-8 bucks a quart, for the price I get T6 for 5.20 a quart.

Honestly if my wife didn't have a Toyota, I'd probably be using it in her car too (calls for a 20 weight oil ultra thin, I switched to 30 weight but prob wouldn't run 40 in it) and as well, I probably will start using it in my Scag with Kawi Vtwin 17 hp engine mower come next oil change.
