Mobil 1 10W30 synthetic and a Mobil 1 M1-210 synthetic filter in both my Terminator and my son's '05 V6.
I think one of the major reasons I feel that Mobil 1 is one of the best oils out there is its current track record as a factory fill for many high performance and luxury vehicles. How many cars come from the factory with Royal Purple in them? How many race teams use Royal Purple in their cars? Few if any...
The following cars also come from the FACTORY with Mobil 1 in their engines:
Bentley Amage & Continental GT Coupe
Cadillac CTS, XLR, SRX and STS
Pontiac GTO
Mitsubishi Lancer Evolution
Mercedes-Benz SLR McLaren
All Mercedes-Benz AMG's
All Porsches
Dodge Viper
Ford Mustang Cobra R
All Aston Martin cars
All Corvette ZO6's.
If it's good enough for these cars it's good enough for my low mileage, barely driven, garage queen Cobra!
