**update** Mpg

i know there has been threads before on mpg. but i'm lazy and don't want to search through them........sorry :think: ive got a flowmaster, k&n airfilter, drive conservatively and running stock 245's right now. in the city im busting out a whopping 10.4 mpg. btw, ive got a hoe with a 350 in it. would changing the plugs, cleaning the injectors give me any kind of mpg boost? or anything at all? thanks in advance

agreed. the loss of backpressure could hurt your mileage. you need rear O2 sims, other wise you are not running with the correct A/F ratio. last i remember hearing is that you run rich in this case.......

just get penzoil, valvoline, etc. all the major brands in oil have a good product. if you want synthetic, mobil 1 or amsoil is the only way to go. mobil 1 is cheaper than amsoil and for the application its just as good.
