Anyone know about this stuff? Never seen it before
yup ran it in my first 6.9 couldnt tell a difference from the rotella that i religiously use. seemed to not burn up as quick idk could just be me.
Try using Chevron Delo, my truck drinks less Delo than Rotella, just my .02.
I've noticed the same thing using Motorcraft instead of Rotella....
I run the Motorcraft 15W40 in my rigs.
has anybody tried the royal purple 15w40? just wondering because they have a pretty good name for themselves. just hand't herd much about the heavy weight usage in diesels........
The royal Purple 15W40 is $34.99 a gallon at my local autozone. I ran royal purple atf in my last IDI's ZF5 and it worked great, smoothed out the 2-3 shift.
