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.

Always use Rotella T6 5W-40 oil in my Super Duty diesel. 2 day shipping and very good price always makes it nice!

Using 5-40 T6 in my 2011 Duramax LML. It offers protection with Michigan cold winters and hot summers.

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.

Rotella T6 Very satisfied. Have used this product in my motorcycles (Honda) for years, Multiple Honda threads recommend this product.

I use it in everything including a VW diesel that is only supposed to use Castrol. I haven't had any engine problems in this car for over 200,000 km.

This is all I use in my truck and this is the best place to buy it in bulk. Always the cheapest price for the best product.

I love Rotella T6 5w40! We put it in all of our cars and since it meets JASO-MA ratings, we put it in all of our ATV's as well!

This is the only oil I will use in my 2014 GMC 2500 Diesel! We pull a 37ft 5th wheel and this make one less thing to ever worry about!

Best Synthetic Oil for an Older 1997 Ford (International) 7.3L Powerstroke with 211,000 miles. Easy Cold Winter Starts. Great Summer Protection
