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.

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

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.

Long over due. 90% of a diesel engine's wear occurs in the first 5 minutes after crank. The 5W should help. Use in 1997 F350 7.3l and 2000 Bobcat.

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

I have well over a 100,000 miles on my 2017 GMC L5P , it does not burn a drop and don’t have to change as often, no issues what do ever

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.

Use in all my vehicles. Truck and Motorcycle and car. Best price. Great oil. Shipping was on time.

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.

Great deal. I bought the bundle of three. I have a diesel so I hope they have a bundle of four deal come out.
