LRP + O2 sensors

Does LRP still stuff up O2 sensors?

I doubt it would do an oxy sensor any harm, as LRP contains no lead, which is the damaging agent.

BTW, why would you want to run LRP, normal unleaded is cheaper, and probably has a higher octane rating than LRP. The alloy heads of geminis already contain hard valve seats, so valve seat recession is not really an issue.

LRP has a higher octane rating than std ULP ... Michael

ulp = 91-92
lrp = 96 (roughly)
caltex pulp = 96
optimax & mobil synergy = 98

Yeah, I thought LRP had a higher octane rating than ULP.
Thanks for the oxy sensor info.

I rang the Mobil or BP customer service line a couple of years ago and was told Super was 96 octane, ULP was about 94-95, and PULP was about 96.

I would have thought LRP would only drop in octane, not keep the same levels.

Thats a couple of years ago I heard LRP only if its lucky has a octane of 86 ron which is pathetic
