Re: Any long-term Rotella T6 users....thoughts..?
I run T6 in my 6.0 Ford with good results, but I also use a pint of Arch-oil AR9100 friction modifier in every oil change.($$$) You can literally hear the difference the arch-oil makes though and I'd bet money it will make my engine last past 300,000 miles. I ran the truck without it for a few weeks once and when I added it, the engine noise was greatly reduced. But that's not the topic of this discussion. I honestly cant say how good T6 by itself is, but I have had Zero oil related problems in 50,000 miles, and I drive hard. I use Mobil one synth in my gasoline tractor and newer mowers. Old stuff gets dino oil as I have 30 qt. of 10w-30 I got from a neighbor a while back.
