What brand motor oil do you use?

Valvoline for everything.

Any particular reason why? I have a buddy of mine that swears by pennzoil...

Origionally Motorcraft... then i went to Quakerstate Horsepower... and now im using Royal Purple all the time...

Royal Purple is AMAZING!!!

I've thought about going to Royal Purple.... kinda expensive though...

it is expensive but when i was on other oil i changed it every 3,000 miles. With RP I do it every 5,000 cuz its a much stronger oil and you can truely feel the difference! Much faster revs and more power. Soon im gonna put RP in the rear differential also.

Whatever happened to that oil that came out a year or two back that supposedly could run 15,000 miles? Did they finally realize that was a stupid idea or something?

I havent heard anything about it in a while...

I run the Motorcraft Synthetic blend, or the Valvoline Durablend. I am running Synthetic Valvoline in the rear diff, and Synblend Valvoline in the front diff. Was running full synthetic Mobile 1 ATF in the trans'/tcase, but it allowed the syncros to slip too much. I am just running plain old NAPA ATF now, but I am going to change it for some Mobile 1 0w-30 soon. It does better with lubricating a gear box (like the M50D) than an ATF fluid can (since ATF is a hydraulic fluid).

i didnt hear about that... what brand was it? the 2011 mustang V6 and GT will only need a oil change every 10,000 miles due to a new oil pan design...

sorry to tell you workdog but your grandpa is way off and i suggest you stop using it (pennzoil) right away its a fact that it clogs all of the oil journals in the crank and sticks to the sides of piston, oil pan,vavle covers heads, and you name it. your are better off running walmart or even a k mart brand or really glue cuz thats what it turns into.

as far as what i run i love royle purple its amazing stuff. i how ever run mobile 1 or valvoline if it leaks lots of oil then i run walmart or the cheapest i can find. the only one i try to keep ppl away from is pennzoil lol i have seen what it can do and its not nice at all its the reason my 5.0 is bonk and needing a full rebuild.

He said he uses Valvoline in his first post... He was just commenting back from when I asked why he uses it... I said a buddy of mine uses Pennzoil...

Valvoline is a good oil. Thats what my dad used to use in all of his vehicles a long time ago... Not a Pennzoil fan but ive personally never used it. My fiance used to use it but i got her using Quaker State synthetic now just like what i used to use before Royal Purple.

just passing on my info bossman lol puttin the word out there to hopefully save my fellow rbr ppl
