Just curious, does adding carb cleaner in the fuel tank remove the led additive?
Also can I use Marvel Mystery oil instead of lead substitute, I have heard the marvel product does the same as the lead additive.
I have used Marvel oil in everything mower, tractor, blower and my old cars and I think it works great...any thoughts?

 

You can run Gummout in your fuel tank! Nowadays, people use Seafoam, Lucas, and such!

I don't think it will take the place of a lead substitute, and it will not remove anything from your fuel tank! Alot of people use it as a top oil, and its really good about freeing up sticky lifters and rings!

Everyday use is probably not necessary!

 

I use the Marvel during oil changes or just befor a long road trip. I think I will keep the fuel additive practice going.
thanks

 

Before I sold my 65 Delta 88, I ran 1 tank with real tetra-ethyl lead. Next tank was sea-foam.

Previously I would mix 1 gallon of 104 octane leaded race fuel per 5 gallons.
