Ahh, OK. Got it.



'03 LS SPORT COUPE 5 SPEED black with teal/silver pinstripe

Alright, put what you want, but I like to race, but I do not have a race motor.
My stock ECO does just fine with regular oil and gas, just as any other would.
If my engine was set up for race, then I would prolly consider the latter.
But since I pay for everything, I go for bang for the buck, and the syns, and high test would just cost me more money for nothing.
