Several people on here have used Shell Rotella and speak highly of it, which version is being used, T6 the full synthetic or T5 the semi-synthetic? Any clutch problems?
I think you can use either really, but I've always used T6 in both my street and race bikes....no problems to speak of.
i think both work, but for a little more, get the t6. I have seen a few oil tests, and the T6 tests just into the top 25% of the oils that were tested for sheer (some bearing test where there's a weighted bearing then something spinning another bearing, wear is measured) . The T was in the lower 75%
Been using the T6 for over a decade no problems. This summer I tried the 15W conventional for shittes n giggles and I feel it shifts better.
Funny you mention that. I've been using T6 on my bikes since it came out, but I've tried Repsol oil and thought it shifted better. But I thought it may have been in my head, and didn't want to bring it up here since Rotella is God round these parts.
