All fuel is pretty much the same because there are only three manufactures refining fuel. The difference is what is added by the individual sellers that can make a difference like detergents, etc. If you are running aluminum heads and are under 10:1 mid grade could work depending on the overall timing/setup on your engine. Because of the 454 torque and the possibility it could be iron headed I would stick with premium just to be safe. I use premium because I like the extra octane and the cleaners in shell V-power. I also run STP every few months to get rid of water buildup.

I'm not saying there is no difference in gas from one brand to another. What is more important is the station. The tanks get water and crap in the bottom. That needs to be cleaned out on a regular basis or it will build up enough that the pumps start pulling it up. There is always some junk on the bottom, that's why the pump doesn't pull from the very bottom. If the station doesn't look like it's being maintained then the tanks probably aren't either.
Another thing to watch out for is buying gas while the tanks are being filled. When they dump the gas in the tanks it stirs up the crap on the bottom. Now most stations these days have filters at the pump but again if the station isn't maintained then the filters probably aren't maintained. |

Royal Dutch Shell
Marathon Exxon/Mobil Shintech Valero Conoco/Phillips BP Murphy Oil Those refineries are all within 100 miles of me, and I may have forgotten a few.. They all make gasoline that has to pass rigorous testing by all sorts of bureaucratic regulating bodies...which also vary by state. I'm pretty sure that the EPA regulates on filling station pump filters being changed on a schedule. |
