We bought the 07GT earlier this year and it has the Ford Racing whipple supercharger. From the feel of it and the lack of intercooler, etc... Im guessing this is the 400hp model. We do not have the manual because it disappeared when the dealer installed it.

What oil should be used for the motor oil? Guessing 5/20 but my research is coming up with the wrong results and the dealership keeps sending me to voicemail.

THanks in advance!

The engine is designed for 5w20, stick to it. I use Royal Purple and it works great on any combination.

I would stick with what manufacture recommends. I use the recommended 5w-30 in my supercharged 4.0

I run Amsoil 5w30

Look up an owners manual online just to be safe. I know my 13 5.0 takes 5w20 and I recommend royal purple as well!

Owners manual was lost. Eventually got a dealer who knew what they were talking about. Same oil weight as before. 5w-30 Mobil 1 went in it.
