Rated 4.5 out of 5 stars.
If you're running a classic car with an engine designed for leaded fuel, you know the struggle.
This is a case of 12 bottles of Gunk M5012 Lead Substitute, and it's New Old Stock (NOS).
Each bottle is 12 ounces.
You add this to your fuel to help lubricate and protect the valve seats, which modern unleaded gas just doesn't do.
It's made by Gunk, a trusted name in automotive chemicals, and manufactured right here in the United States.
The UPC is 078698135014.
If you want to keep that old engine happy and prevent valve recession, this is the stuff to have on the shelf.
A full case means you're set for a while.
