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.

I have been running T6 Rotella in my Envoy, this vehicle has 343000 miles on it now and continues to run very well.

These work great on Subaru, I used them on turbo and non turbo, it stopped eating oil. Highly recommend.

I personally have driven a diesel vehicle with this oil in it for 250,000 miles and find it to be one of the best oils mile for mile,

Been using this oil in my cars for several years. And the price is fantastic for a full synthetic too, great stuff.

I have a 2009 Silverado 3500HD. This is the first time I've used Full Synthetic during an oil change. The Duramax loves it.

Perfect oil for the Cummins 6.7L in my Ram 2500 Diesel. Good price on an item I cant find in the local Auto Zone, with free 2-day shipping to boot!

I run rotella T6 in my S250 Bobcat, my 6.7 powerstroke, my diesel Volkswagen jetta and my ATV, we are all happy about it and running strong!

I have a bandit 1200 GSF Runs excellent with this oil with my wet clutch and its rated Jaso Ma. Great price. Thanks Walmart !!

Use in my 2008 f150 had a cam phazer bad i mean bad so bad engine would stall. put 0w40 in disappered. Gone. Run up to 16000k between changes.
