I've been seeing in a lot of magazine articals when they talk about upgrading 1st & 2nd gen Camaros to efi, that they reccommend replacing fuel lines because of additives added since 2000 eating up older fuel lines. Is this a problem we should be concerned with? Is this possibly the source of the plugged up fuel pressure regulators we've seen on our cars recently? Is this also the source of fuel filter problems we've seen on cars built before 2000?

I know that I pretty much no longer use any sort of Octane boosts in any of my cars. I have also stopped purchasing a fuel injectoin cleaner as well. All it took for me was the residue that the NOS Octane Booster leaves behind and fouled plugs to get me to stop wasting my money on it and just purchase race fuel

Most of the off-the-shelf octane boosters are junk. Most of them use MMT which leaves a nice orange residue all over the engine internals - pistons, combustion chambers and spark plugs. This stuff likes to foul spark plugs. Race gas is the better solution.

Way back when I used some stuff by Moroso that seemed to be pretty good. I think PAW sells it.

Plus, it came in a gallon bottle so you got much better bang for your buck. All you had to do was measure out a few ounces at each fill up. I used to carry it around in my '69 El Camino with a measuring bottle.

The additives I'm asking about are not aftermarket. It's the garbage the oil companies are putting in the fuel along with oxygenation to make them burn cleaner. I know for a number of years now the additives they put in diesel fuels have resulted in neoprene parts in the fuel system disolving every 100,000 miles. That may seem like a lot until you realise that the typical diesel truck runs 200,000-250,000 miles per year.

I know that MTBE didn't get along with the fuel systems on certain makes. I remember seeing news stories about Nissans being the main victims.

Interesting, thanks for getting us on the right topic Russ
