Can avgas be safely used in the rx-7? I heard the airport here sells 100 low lead for less than $2/gallon. I want to use it instead of the $4/gallon sunoco 100.

Trick with them is you will be hard pressed to find one that will let you

pump it into the car, you have to bring gas cans.

There is a little airport here, Republican Airport, they will sell you the gas

after you pay the guy, then stand outside the fence while they fill your gas cans.

Take it you have no cats and no care about gas mileage(o2)

There, go spill the beans and ruin it for everyone.LOL

ahah

lol, there is nothing illegal about putting gas into cans, its pumping it right into the car where the problem lies.

what you need is a dummy gas can in the trunk that just goes into the gas tank, so you just put gas into the can in the trunk https://www.nopistons.com/forums/pub...DIR#>/wink.png

By law gas cans have to be on the ground, some **** about static electricity.

When you go to the gas station you will see there should be a little sign saying to put gas cans on the floor before dispensing fuel into them.

The little airport over here wont even let a car or a person NEAR the pump

or the gas truck.

hmm ok, i was trying to follow the letter of the law and not the spirit, oh well

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



mike

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.







IIIIIIIII LLLLLOOOOOOOOVVVVVEEEEEE IIIIIIIIIIIIIITTTTTTTTTTTT. https://www.nopistons.com/forums/pub...IR#>/boink.gif :yum:





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.

ive heard that too, theres some formulation/ additive difference?



mike

I ran avgas for about a year in my FD. It was 100LL and never had any issues. I ran it on a stock motor and stock turbos. It never cost me a thing so I used it all the time.
