Fuel Question for diesel
Cummins 8.3L ATC 6
Can I blend in auto gas, & av-gas in with the diesel @ ?? %, 10 or 20%??
WHY..... I sold my Cessna 3 years ago & I burnt a mix of 80% auto & 20% 100LL because of lead fouling to small bore Continental engines, an O-300 6 cylinder. The engine was design for 0.5grams of lead that was in 80/87 & now the 100LL has 2.0 grams of lead which causes plug fouling & exhaust valve stem build up, the engine did not run hot enough. My mix work great, clean plugs & no build up anywhere in the combustion area......
I have 40 gallons of mix & 9 gallons of 100LL & 50 gallons of OLD (8+years) auto gas in my fuel shed sealed up in 55 gallon barrels.
I CAN'T BURN THESE FUELS IN MY CARS & the fuel is old, 4 years on the airplane mix & the 8+ on the auto. They all run good in the lawn mower.
Since diesel engines are built much stronger for Ceptane not Octane fuels can I blend in say 1 Gallon to 10 diesel with out any troubles?? I have heard of people fueling with auto gas but should have been diesel & caught the mistake before pumping to much, changed to fill with diesel & drove off with no troubles.
WHAT YOU ALL THINK???

Diesel is used as fuel for the engine , BUT it's also used as a lubricant and coolant in the ; injector pump and injectors, gas is a dry fuel and can do serious damage to the areas in the pump that produce the highest pressure in the injector pump and score the moving parts causing a drop in the pressure they produce the same can happen in the injector itself .
The drop in efficacy might not be felt immediately but there will be long term effects, probably shortening the service life of the parts.
I've replaced injector pumps on trucks that didn't make two miles with a concentration of gas in the diesel ; owners though they'd just drive to the shop to get the tank drained.

I sure wouldn't do it. Gasoline in diesel for modern diesel engines just don't play well together as Skip indicated. I saw what happened when someone accidentally pumped about 10 gallons of gas in his diesel pusher tank. The expense of the engine repair was out of this world!

In a modern diesel engine I would not mix.
What I would do is list it for sale on Craig's List or Facebook Market place. Boaters, off road motorcycle riders, classic car/motorcycle owners will garb it as it's ethanol free and the added lead shouldn't hurt the engine. Not sure how it might have aged but being high octane and in a sealed drum might not have degraded too much. List at 10-15% off what E10 gas is going for locally per gallon. Problem gone in an hour.

DO NOT mix gasoline in any quantity with diesel fuel unless you intend to rebuild the engine and fuel system. The injectors and fuel pump depend on the fuel for lubrication.

Also gasoline burns much faster and will probably ignite before the intake valves closes fully due to higher operating temperatures in the cylinder. It would be auto-ignition far before it is designed. RESULT, you may get to buy a new $30,000 engine.
Yes, 40-50 years ago truckers would mix 1G gas into 50G diesel fuel in winter to prevent fuel gelling; but those engines were built much differently.
Today that would cause a diesel engine to run so hot, internal damage is sure to occur.

NO...........NO.........NO
You can blend grades of diesel, kerosene but NOT GASOLINE with diesel and use it in your Diesel Engine.

I know you said you can't burn it in your cars but why not? I recently had 5 gallons of water contaminated 2 stroke gasoline that I separated in a big glass jar and ran thru a funnel filter and have been burning it off in a gasser car at 1 gallon per 20 gallon fillup. If you dilute it enough I don't see why that would be a problem.
I was not willing to put it in any of my diesel vehicles although it would probably be OK in my old Powerstroke at 40:1 but it's just easier to use in the car. I actually spent more money on stuff to clean it up than it was worth but it was the best way I knew to dispose of it in a responsible manner.

Can't because of the lead & Lacquer in it
The lead will fowl up the catalytic converter, only takes a small amount to ruin a converter. The computer monitoring the exhaust manifold O2 & down stream, after the converter O2 sensors will feed bad info to the computer. As for the OLD auto gas, it has changed color to to a redish & lost octane from being exposed to the air through breathing in an old RV fuel tank that it was in for years.
All of it burns good in "L" head low compression engines in lawn mowers. But new mowers are higher compression OHV type. My 2000 Weed Eater 38" lawn tractor with 12 hp Briggs runs on it good & that mower ran on Jet "A" good too, just can't cold start with Jet "A".
I have replaced my diesel engine & it was not cheap $10,250 long block & $5,700 @ Cummins for the injector pump. So much for the kid's inheritance!

In that case I would start inquiring about hazardous waste disposal, or just start disposing of a few gallons at a time at you local hazardous waste center. Ours is good about taking fuels but in limited quantities, if you try and take a whole barrel they will start screaming that you are commercial and "get out". We have enough locations that it's possible to "spread the love" with a little driving around.
