Fuel Injector Question

[Craig K.]

Is there any risk of damage over the longer term when running leaded gas through fuel injectors?

Reason why I am asking is that my brother is looking at bumping up the compression ratio in his ALMS engines and running leaded 112+ octane, where as these engines are normally running unleaded.

Please let me know what you guys think.

I know lead kills 02 sensors but I don't know about the injectors

I don't believe it hurts the injectors but I know it will kill the o2.

[Craig K.]

good point, the systems that these cars run do have O2's.

Forgot all about that, thanks guys!
