What are you guys doing to keep your engines going on this new gas with no lead additive? My 276 Hemi is original, no hardened seats in the heads and I am wondering how long it will last on today gas. Do you guys run lead additive?

What are your thoughts?

.......is not a problem for your engine. I have noticed that the new formulations break down very quickly. Use some "stabil" or equivalent went not driving the car.

Have a nice day

I was pondering this same question the other day. I suppose the newer formulations have PTFE or some other such additive to keep the upper end properly lubricated? Or am i just high from smelling too much gas.... :shock:

As long as you don't run the car real hard you don't have to worry about it. That is just another one of those rumors when something changes. I had a old farm tractor that I ran a lot harder than we run are cars and it never gave a problem.

I have read that the DeSotos of certain years have hardened seats. So unless you run the car real hard, you should have no problems. I have read this probably 3 or 4 times on this site. My 53 has no problems and we have reformulated fuel with ethanol. However, my car is not a daily driver. My early 70's 390 boat engine is having a problem that could be due to unleaded fuel - not sure yet. I ran it hard, real hard for 15 summers straight every weekend. I have not had time to get this figured out but I suspect the valves or seats. But compression is what it always has been.
