In my motorcycle - 2015 BMWR1200GSA - for over 80,000miles In my 2001 Nissan Pahfinder with VQ35 engine. In my Honda scooter (not that the scooter cares what oil it gets) 6.0 Powestroke diesels love this stuff. (I used to be a diesel mechanic)

I have been using the Rotella T4 15w40 in my Honda Goldwing GL1100 for a number of years. Smooth transmission and no clutch slip. 82000 miles done and no problems. The T4 along with T6 is JASO MA2 compliant.

Shell Rotella T6 oil is the best oil I choose for my International 7.3L. Great low price! Seems to improve mileage and engine spins quicker during startup!

This is a great product but can’t seem to find it.

I've used T6 oil in everything from diesel trucks to my friend's 2007 Mercedes C350! this stuff holds up to anything that gets thrown at it!

I've been using this oil in my 2010 Genesis Coupe 2.0T for almost 2 years now. Love it! Wouldn't use anything else in it.

Have been using this in my R1200 GSA LC engine for 3 years now. Also used it in my Honda VFR800 and 2006 GSXR1000. Always has been a great oil.

The good stuff: Shell Rotella for my Ford Transit 350HD diesel RV - Sam’s has best price and with Plus membership I get free shipping.

best all around oil. I use it in everything including my lawn mower. one of the few oils that still contains zinc which helps lubrication.

My oil pressure is sitting back up where I like it and reduced engine noise especially on cold starts. Engine sounds much better over all.
