Question type: General

Leaded or unleaded?

2 Answers


I'm surprised you can still purchase leaded gas. Where are you from? Use the highest unleaded octane you can find and you should be good.

Highest unleaded octane. Thank You. Actually leaded gas is unavailable, i live in CA. But just in case i needed to buy a lead substitute for it.
