Daily.

I use it for the drift car but as of lately there’s been a shortage and I don’t wanna change oils. Can we fix this. It’s the only oil I use.

more than just a diesel oil!

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!

Great product at a great price

This is the only oil I use on my 2007 F350 6.0l Powerstroke diesel. Walmart has it for the best price.

Best Oil I have used

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.
