I used Mobil 1 for about 40,000 miles, recently switched to Pennzoil Platinum. I bought car with 38k and has 97k now without any problems whatsoever, and car is highy modded. Some people claim you should use Amsoil or Royal Purple, but I never thought it was necessary. Its more in changing it regularly and using a good oil filter i.e. not a Fram. All my dads old school muscle head mechanic buddies insist that even most full synthetics are overkill, but I do it anyway.

I have been using Mobil1. I can't tell the difference at all from normal oil, but I don't have to change my oil until I get to 5K miles, unlike 3K with normal oil.

I did use Mobil 1... now I use Red Line.

Amsoil or Red Line>Royal Purple>Mobil 1 IMO

i used mobil 1 syn religiously for years in my stangs, and they loved it.

i switched to royal purple syn oil in my big power stangs, and actually gained 3-5 rwhp on average over mobil 1.

If you start using syn in your car, DO NOT switch back to regilar oil afterwards.,......not good
