I've seen these little chips advertised as an add on that can increase the miserable gas mileage on the V8 SRX......they are probably junk, but has anyone had experence with them or maybe knows of something else that might help. I truly love the vehicle except for this serious problem with gas $4+ gal.
Also I know premium is recommended but is reg a real no no?? Has anyone tried reg w/ an octane buster? Don't know if it would work or if any $s are saved.................thanks
