I have a 95 gt with only 91000, i want to use royal purple, cuz i heard that they are really good! I was wondering what kind and what grade 10w-30 or wat? Thanks for your suggestions, and i will go give an update once i get a response thanks.

you'll get mixed responses on here. i remember seeing that RP doesnt even meet the latest standards for motor oil. whats that all about? [&:]

me? on a motor that old i'd stick with a quality "dino" oil in the 10w40 flavor. personally I have always found good luck with pennzoil. im using pennz 5w20 full syn in my 2006 GT and its done me well so far.

for what its worth, moble 1 is also very good oil - but i did a big research on all the major manufacturers once and redline actually spec'd out to be the best.

I use only Lucas 10w30. It costs about .40 less than RP.

What, no one recommending Amsoil? There is almost always an Amsoil salesman who jumps in on these oil threads.

I use non-syn oil in everthing I own from Cummins diesel Ram to 56 T'bird, two Harleys, Jeep,the '93 LX, a diesel Kubota, Cub ZTR, etc. I change at factory recommended intervals and use factory suggested weight. I don't worry about brand as long as the container shows it meets the latest specs. Of course I use diesel oil in the diesels.

The only time I vary from that is a radical built motor, which I don't own any more.

most of my cars take 10w-30 since they are usually all 100k+, but my cobra is on a diet of 5w20 dino oil, and 0w20 mobil1 after the break-in

use the walmart super tech stuff. it has the stamp of approval, and its cheap as hell...

So that wasn't your cobra that was wrecked?
