Question About Diesel Fuel Treatment

I have several old diesel engines and equipment dating back to 1938,I use stabil and 1 oz. per gallon 2 cycle oil. Works fine so far, 2 cycle oil lubricates and is desighned to burn. Wall Mart has it for around 11.00 dollars A gallon,and its made in the U.S.A.

I'm a Power Service user, no particular reason other than I've always done it that way!👋

Be careful what you use for an additive for an on-road truck, if you "DOT'ed", they may/will dip your tank looking for off-road diesel. I do repair jobs on various on-road trucks and each owner has some various "snake-oil" in the tool box that he thinks is great and is always willing to give you a "sample". Power Service and one called "Lubricator" in a yellow jug comes to mind. I usually dump whatever they offer in my off-road bulk tank.

For the off road stuff, I use two stroke oil as an additive, usually about a quart per ten gallons of diesel. For winter use, I use half and half, diesel and heating oil plus the two stroke oil.

I use power service in my fuel--home heating oil---its supposed to increase lubrication, raise the cetane level, and clean the injectors. :rolleyes2:

Back to the original question: Can you clarify if you are using new on-road, low sulfer diesel in your old machines? Or do you have off road (red)? I know some areas are now required to sell off road (red) diesel in low-sulfer edition. I'm not sure if furnace oil has that distinction yet.

I have a Mercedes diesel wagon; in California they can't check your passenger car fuel like a truck which must have commercial plates. Still, I haven't had a justifiable reason to buy red diesel until I got my D2, but its still not worth having money tied up in large quanities of fuel for my small usage

Don't kid yourself that red diesel is any better than road diesel. I understand in most states it is exactly the same stuff with the red dye in it so it can be sold without road taxes.

I add 1 qt of non-detergent 30 W oil to ten gallons of diesel. I will use 40 W when I can get it.

I try to get some in the Cats but they are more forgiving, they are designed to run on anything. I am particularly religious about treating the VW diesels and 6.9 Ford. There is so much going on in those rotary pumps, they need all the lubrication they can get.

My thinking is the additives in ATF may not be good for injection pump seals. Diesels are made to run on oil, diesel oil, motor oil as long as it is thin enough to go through the system
