What Kind Of Synthetic Oil Does Everybody Use?

[swl987]

on the amsoil website they say that their oil wins in every test. castrol syntec probably comes in second.

I use Motorcraft 5W-20 synthetic blend.

Edit: Now that I have my Cobra I use Mobil1 5W-30 synthetic with Motorcraft FL-820S filter. I got too much valvetrain noise with the above oil that I used on my GT.

why do you use 5w30 i thought it takes 5w20?

 

[Kilgore Trout]

I would use Amsoil if it was available here...

mobil 1/royal purple 5w30,

castrol syntec is not a true sythetic

 

[shotime]

Amsoil 5w20 for motor oil, along with their severe duty gear oil and sythetic atf for the tranny fluid. Hasn't ever let me down and the extended drain is awesome! Worth the extra loot, IMHO.

Currently have Mobil 1 5w30 in there with a Mobil 1 filter...

K&N filter
Mobil 1 5W-30 4 quarts

Motorcraft blend in two car, FULL boat in the 01 Cobra.
