I’ve been using this product for years in my classic cars. Local auto parts store stopped carrying it. Glad I found it.

This lead substitute will presumably work as advertised. Too soon for me to know….but it has a strong odor. Use caution when adding it to your tank.

The truck seems to be running just fine, I'm not sure if I need lead for the valve seats or not but it's 60 years old so I don't think I'm hurting it. At $10 for a 20 gallon treatment i don't feel like it's breaking the bank.

Seems to work well for my 65 impala, however also need a zink additive for the oil. Both products helps my old car run great. No more smoking or noises. Both were minimal, but now gone.

I have an old 9.5 HP Evinrude outboard that requires leaded gas. The gas today is too corrosive to run in old outboards. I still disconnect the fuel line and let the motor run out of gas before pulling my boat out of the lake, I do that with all my small motors.

I have a 57 Tbird and I have to use this because my valve seats have not been hardened. It works great and the price I paid is way cheaper than at the parts store.
