Does a stock turbo dsm have knock on 93 octane?

[LASERLX]

has anyone ever had a logger on a nearly stock dsm or maybe even a mildly boosted (say 15 psi).....just curious

I see a lot of guys run leaded gas at the track? Is this ok for the o2 sensor?

thanks

Leaded gas is OK to use once in a while. Unleaded is optimal, but not always available at the track...

Over time, leaded gas will kill your o2 sensor and catalytic converter.

I run 15 psi on my car which is stock and with a logger no knock at all.


As longer as your car is in good running condition you will be fine.
