I know that the flex fuel engines have a "bigger" injector. Now, does this contribute to noisy engine? I have a lot of injector noise, I presume, at all speeds/RPMs. Of course, my baby has only under 2000miles, had its first oil change to 0w20 mobil1 and is a wee bit smoother. But... ?
I do not run E85 or have I ever. Only top tier gas.
