Yea I have not cats, and the car gets such bad gas millage that it doesn't really matter if the 02 sensor fouls up. Remember, the 3rd gens go into closed loop read off the maps as soon as you get on boost. Open loop is only below like 3000 rpm while cruising. Eventually I'll just get a heated sensor.

Still, no one answered my question. Is it ok to run in our cars without damaging anything?

leaded gas will clog the cats and foul the 02 sensor

Yes! You're fine, from what i have read.. https://www.nopistons.com/forums/pub...DIR#>/wink.png

I thought I told you in the other thread. It's just high octane gasoline with lead. You got closed loop and open loop mixed up.

ok, i see

I need to ask the plane shops here. i used to be a lineman with seaplanes. I think ,cant recall for sure, that lead was import as a lubricant particulant for the valve seat in the time before late 70's. But the metal in todays engine and the zins and phoshate in the oils kinda eliminate the need.Also I think the lead raised the octain but with lead being so big of an enviro deal maybe todays avgas uses more modern octain boosting chemistry.

If I remember to ask I'll post up.

I have heard the only reason av gas is so cheap is because the gov doesn't tax it the same way they tax car gas. I belive 100 oct leaded av gas is the same as 100 oct leaded car race gas. Only the car gas has a heavy tax on it. The airports are not allowed to let you fill cars has they would be cheating the law. But if you bring a can and say it's for a plane you might get buy. I personally have never done it but know people who fill up with 100 oct av gas for track days

Av gas is the **** when it burns it smells kinda like bubble gum.

I think I've been sniffing it too much what do you guys think

I live one minute from a private airport and always fill my tank with Avgas - in my Jet Ski https://www.nopistons.com/forums/pub...#>/biggrin.png



Crispeed has told me adamantly NOT to use it on my car. I forgot why, but he was very clear on the "don't do it" part.
