I just found out that I can get free gas here at the airport. It's 100 low lead that we sump off of airplanes each morning. We use it to run 4 cycle lawn mowers and other stuff around here. We have so much that employees can get it for free. I've got my 59 F100 with a 1966 390 and I've got the 1967 Econoline with a 70's 350. I don't drive either of them to work very often because they **** gas. This could change all of that. Who cares about gas mileage if gas is free? Anyway, my question is this? Is there some reason that I can't run leaded gas anymore? I am told that the lead with eat your cat convertor which I obviously don't have. I seem to recall that I couldn't run unleaded back in the day unless I had hardened valve seats but never heard anything about the other way. Totally safe?
Totally fine on your older vehicles. BTW, I hate you The price at the pumps up here is around $1.03 per Liter. It never came down too far after Katrina... Good on you! Don't let too many people know if you're running it in your car, the government hates people not paying road tax on their fuel. Flatman
Righteous! Thanks man. I thought I was good but it just seemed too good to be true. Rest ***ured, something bad will happen to me later to make up for this.
Don't get caught with it in your tank. It's not designated for road use, and doesn't have the taxes they slap on "car gas" on it. I think the penalties are pretty heavy, like $150 per gallon? That said, if it's free.......I always use free stuff.
i'm not trying to start a big debate with my opinion on using Av gas in cars...just stating my experience my father gave me about 500 gallons to burn when he decided to get rid of his underground storage tank. i used it in my draily driver at the time..a `66 chevy with a 283. it ran like **** , and i quit using it your experience may be completely differnet
Do you have a money tree in your back yard,too,or do people just leave bushel baskets of money on your front lawn??? You are soooooo lucky.
I'd strain it first since it is sump gas but what problem did you have? I don't see how it would run bad on 100 octane fuel?
av gas octane is rated differently than road gas, and I read that it *can* cause rubber and plastic to swell and dry out. 100 octane av gas is something like 93 octane
I've never run AV Gas but what I was always told was that it burned hotter than automotive gas. So not first hand experience but was the general concensous ( sp?) of the crowd I came up around. The lead certainly won't hurt you motor that's for sure. And I think that the whole clogging up your cat thing was just put out to keep folks from running leaded gas in smogger motors. I ran a late model ( at the time) cat equiped efi truck for 80,000 miles in Mexico ( in the late '80s) no-lead was not available and at the time mexican gas was notoriously dirty. Ohter than change out a fuelfilter on a regular basis which I would have had to do anyway I never had a problem with the cat or the induction system. I guess it could have been a fluke. Ya know what they say ( whoever they are) " Ignorance is bliss."
I heard from somewhere, (well, I think I remember it was a particular Aussie, but I'm not sure,) leaded gas will destroy platinum tipped spark plugs almost instantly.
I used to pump that stuff. We put it into our lawnmowers when we ran out of regular gas, BUT I think you'll want to do some research before you start using that stuff - I believe "low lead" aviation fuel has NO lead at all. We were told (by our certified mechanic) that it was terrible for cars, because it does not have ANYTHING in it to lubricate valves. This isn't a problem in small planes, because they automatically rebuild the motors at regular intervals (so many hours of operation). Pump gas has additives in it that this stuff just doesn't have. It looks and smells different, and I think this is why.
Doc, I had never heard that. I don't normally run platnum plugs or leaded gas but its damned good to know.
the one about them catching you....we have folks here get caught for using Illegal deisel....they get caught because it has a different color to it... Oh and did ya think to Google the words "low lead av gas"? I did and you will find some interesting info....
When I was young, in a time long, long, ago, in a galaxie far far away----Oh--Sorry about that----The farmers in Saskatchewan could buy gasoline for their tractors, at about half the price of pump gas, because they didn't have to pay "road tax" on it. This gasoline was dyed blue, so was instantly recognizeable. If the Mounties pulled you over in a spot check, they had a siphon bulb with a clear hose, and they would stick it down your cars gas filler and **** some gas up into the clear tube. If it come up blue, you were in very deep ****!!!! A friend of mine (farmers son) had installed a second gas tank in his 52 Chev trunk, then diconnected and plugged the real gas tank outlet.---he always burned tractor gas. (The farmers out west had their own storage tanks and pumps). He kept about a quarter tank of pump gas in the old gas tank, just to keep the Mounties happy at the roadside checks.
100 lowlead does contain TEL about 4 times as much as leaded auto gas used to have.in fact, it builds up and causes grey sludge in the oil and can foul out spark plugs with lead deposits.it is also harmful to platinum plugs and cats.onthe plus side its not harmful to valves,(an old wives tale)you can crank the timing up and it sure smells good going down the road!
Yeah, I'm pretty confident in the lead content too. That's what seems to be plug up the cats on anything with a converter.
