Now that I am nearing the end to the fuel tank cleaning process there is the question of fuel. Aviation gasoline seems to be a viable option. No ethanol is the main thing but equally important is storage.

The question is what if any problems could happen with using 100 octane low lead?

Will the catalytic converters be affected and if so should I remove them?

Will the timing be okay? Or do I need to adjust the timing to avoid fuel continuing to burn past the valves?

Are there any other potential problems?

Have a productive day.

Model and year of car?

sorry for not being clear.

I only need to achieve stability in the fuel as I am dealing with bad gas problems now and do not want the same to occur again before the car is in regular use.

I hope to fill the tank once it is back in the car but it could be months before the car is on the road.

Yes, leaded fuel will ruin the converters, even this so called 'Low lead'.
I do not think Av-gas will last any longer than regular gas, the only advantage is that it does not have ethanol in it. How long will the car be sitting? Likely the best bet would be to let it sit with very little gas in it.

If you are near a place with boats, ask around at marinas and fuel docks--some have ethanol free fuel for boats and fishermen. While there, pick up Marine Sta-Bil, it is far better at keeping fuel than the RV/land vehicle version.

Good luck getting your car on an airport to be fueled by a fuel truck, depending on which airfield is handy. The smaller the better (airport, that is) that actually has 100LL.

Used to be one could just drive up to an FBO and they'd dispense gas but with all the new laws protecting us from ourselves, you are likely viewed as a potential whacko for wanting to do so.

Likely yes. Our W124 230TE/5sp's catalytic was given fits by fuel that had some lead in it. Does your car have actual catalytics (as we know the today) or thermal reactors as found on some cars of that era? I've briefly owned some 78 79 cars and they had a slightly different predecessor.

That depends... will anyone check? I recall how hard it was to get a muffler shop to delete the cats on my car when I was driving through CA and one of them clogged up. I found the most hillbilly shop near Eureka CA and the guy did it.

Your wallet won't be happy with filling up using 100LL

Gotta drop the exhaust on my 108, oh joy!

Good luck!

Bio:

I'm with Palolo on this; use the Marine Sta-bil irrespective of the fuel you obtain. The Avgas will have considerable storage stability vs. auto fuel. If at all possible, install the tank but do not fill up until you are ready to operate the car regularly. If you are able to do this, then all that will be required is to spray the inside of the tank with the likes of WD-40, but otherwise leave it empty.

Thank you all for your ideas.
I had planned on splashing kerosene in the tank to coat it with light oil to prevent rust.
A reply from a member of the M100 group forum said that he had stored a 1969 Mercedes for 15 years with av-gas and that it started and ran fine. He also mentioned that that "low lead" is in fact high lead in comparison to road gas and that airplanes have a control to lean the mixture to prevent lead buildup on the plugs.

I will investigate what exactly the cats are. This was the beginning of the EPA building our cars for our protection.

Our small town airport is like the good old days where we can drive up to the pump. I intend on driving up with a truck and fill up a barrel. They even have a pump at the end of the runway for the locals that is almost a dollar cheaper than the standard public pumps.

certain airports carry this new fuel
