With gas prices @ $3.51 per gallon, I've already started catching the bus and I'm even considering selling my LS. I just changed spark plugs last weekend, some pretty clean denso plugs came out (just bought the car last nov.), the wires, cap and rotor looked pretty dirty though. The car pulls fine so im not suspecting theyre hurting the mpg, but I'm not interested in dumping money into this car unless I know theres a possiblility that I might be able to make at least 300 to the tank.

Any responces would be apperciated, Thanks!

Oh, I also fill up at Chevron if that makes any difference..
