anything wrong with leaded fuel?

[Geoff]

Is there anything wrong with running leaded fuel in our cars? Reason i ask is that i live on an airport and they have 100LL(low lead) for sale for only $2.10 a gallon....
Would it be bad if just every once in a while?

It'll wreck your catalytic converter (if you have one, hehe).

[Geoff]

besides that nothing?

i think it skrews up ur O2 sensor as well.

Use it in moderation and things will be ok. Even though it is called "Low Lead", it is far from unleaded. It contains an unbelievable amount of lead and the converted SAE octane rating is around 135. It also contains alot of anti-freezing/gelling additives that you don't want too many of. Mix it with unleaded well.

haha, thats sweet info thanks. Do you have any recomendation on proportions to use?

i used 114 leaded race gas at the drags all summer in about a 30% mix. no detrimental effects to the O2 sensor. it takes a very long time for leaded gas to ruin an O2 sensor, especially if it is pre-heated prior to starting the car.

I run 70-100% race gas in my GLH daily. never had a problem with my o2 yet, I'd say I've run at least 150 gallon through.
