I have used Penzoil Full Synthetic in my mustang for years. Does anyone use anything else?

 

Mobil 1 full synthetic is my favorite. Everybody has their own personal opinion on which synthetic is "better".

 

I run Mobil 1 in my truck since new but for my daily driver @180K i just run Castrol GTX high mileage.....But like Camaro69 said everyone has there own opinions about what full synthetic they run

 

I've used Pennzoil, Castrol, and Mobil 1 and liked them all. There's Castrol HM in my Jeep while the Camaro has Pennzoil HM. It's getting switched for Castrol Edge when spring rolls around. Personally, I find the filter to be more important than the oil. Oil is strictly regulated while the filters not so much. A quality oil filter (K & N, Wix, Purolator PureOne, Bosch DP, Mobil 1) will do more good.

 

I run European 0 40. Works great.

 

I run standard dino castrol gtx 10w30 in the race car, although it gets changed basically every other race.

Synthetic oils are an absolute PAIN in the *** to clean off the track should something ever happen, most drag cars you see will be running a dino oil because of that

 

But, Chevy engines don't spill their guts!

 

if you aren't breaking parts, you aren't going fast enough!!

 

I think Tommy Morrison would disagree.
heard him say when things break it was because someone didn't pay attention to the details. And his cars were plenty fast.

He even built me a bullet proof rear end for my Corvette.


As for the original subject, I like Mobil 1. as said it's pretty much a persoanl preference.

 

I went with penzoil Full Synthetic
