Thanks Dallara...the voice of reason. GM builds awesome push rod natuarally aspirated muscle-cars, namely Corvettes and CTS-V's. The Corvettes particularly have been winning the GT1 class for many years with no competition and on Mobil 1 lubricant.

People will always feel there is somewhere for their rides. In this case it's talk of a better designed lubricant. Amsoil, Royal Purple and others are, great products. Are they worth the extra money? Will they deliver the difference over the MFG's recommended Mobil 1? I say no.

If it makes you feel like your car will perform better, by all means buy it. Your Local Tuner will probably love you if it's what tey are selling. They too have to make a living.

My Tuner, Quality Motorsports, Lewisville, TX highly recommends Mobil 1. They're C6 Corvette Forum Vendors and stay very busy in a tight economy developing and delivering perfomance packages for many of the C5/C6 LS based motors throughout the country and now they've taken on the CTS-V. In fact the owner Patrick Sparks just took delivery of an 09 silver CTS V Monday 6/29.

Mobil 1 all the way!!
