As long as it has an applicable API rating and JASO MA certification, it's good. The label on my Rotella T bottle indicates it's SM rated and is JASO MA certified. Good enough for me. It worked fine in my KLR when I had it, and so far my Versys likes it.

Just my opinion,

LittleSteve My $0.02 worth on Rotella T.
It is really good oil at a much better price than synthetics, and if you change your oil at short intervals like a lot of us do,1,200 - 2,500 miles, anyways, synthetic isn't really a very good option where it might serve better in an engine that go longer between changes.
I tried Mobile 1 20/50 motorcycle oil for a very short time and thought the bike ran better when I put the Rotella T in, and I felt a lot better about the price.
If you do the reseach and learn about oils ya might find that the ones developed for modern Diesels are continually tested.
Good to know what's going on with them as they are continually tweeking them.
Besides, to me the KLR is a bit of a tractor so I figured it wouldn't hurt to put tractor oil in it...
As far as burning oil, I think part of it, not all, has to do with how it broke in, and how it was broke in, a combination if you will.

I've also had very good results with Walmart's 15w-40 diesel oil. About the only one I didn't care for was Chevron's Delo 15w-40.. It didn't feel like it helped the bike shift as well as Rotella/Walmart does.
May give it a try because I use 100% synthetic now and it is doing nothing but burning through the bike at $65+taxes for four litres

JGTREE I have a 2012 and I swear it's burning oil after I hit 1k miles. I run rotella in it too. And as far as I know it's all diesel oil.its formulated without all the detergents in regular oil I think.

Not all 2008 models have the oil burning affliction, so if your KLR does not then be happy and change oil at the recommended schedule. I have an oil burner on long highway trips but other than that my KLR works fine on commuting and offroading with no oil consumption, so I stick to the regular schedule for mine.

byker To answer the question, I have used it in my 08 since new and it now has 80,0000+ kilometers. I have had no problem and buy it on sale in the large pail. Good stuff!
