I follow others' suggestion to supplement my diesel fuel with 2 cycle/stroke oil that I purchase at Walmart for around $12/gal.. I use a ratio of 1qt./50 gallons of fuel.
Adding the supplement into the fuel tank was a pain, especially when the gallon container was near empty. Pictured is a nifty spout I also purchased at Walmart. The spout does not come with a cap. I found the cap from a 85/90w 1 qt. "rear end oil" container fit well. Just thought this may interest others. Take care.

Maybe Rusty can suggest a specific brand for lubricating Diesel Injection pumps. Maybe it does not matter what brand. I use Citgo Super guard Low Smoke. I can check the price I pay later.

Ted, How much per ounce did you pay for the 2 cycle oil you are adding?

128 fl.oz./gal @ $12+/gal = 10 cents / oz. albeit "Old Math"

Any 2-cycle oil will do. No benefit to the high-priced stuff like Quicksilver.

What is the benefit of doing this? I have a ford 7.3 in a one ton truck.

I added 2-cycle oil to my 6.9L E350 for ~12 years and 80,000 miles (since the intro of ULSD). Never an IP issue. Whether adding the oil helped, I don't know - but it can't hurt.

We use Howes products, anti gel and Meaner Cleaner. You might want to put something in that addresses algae growth and water in fuel.
Detroit 60 series with 1,200,000 miles when sold, never injector problem.
Cummins 600 going at 800,000 miles now.
7.3 Ford 95,000 miles, no problems
And over the years a 5.9 Cummins, 3208 CAT and a 6V71
Keep on trucking

BTW no they (Thermoking) telling me to use that Diesel Kleen Cetane Boost. They say Howes clogs my Espar diesel fuel heater up in the burn chamber. Who knows. Only thing ever the piston broke in the Detroit at 999,946 miles, fuel pump went out when they got the new ULSD diesel years ago

Ford has a 6.0 diesel v8 engine that energizes the injectors with high pressure oil drawn from the engine sump. These tend to gum up without additives and the question to Rusty is: with the hundreds of additives available for diesel engines just what component are we looking for to protect and clean the internals of these type of engines?

PowerStroke engines' injectors have been an enigma since introduction. I'm speculating, but using synthetic oil and changing according to the "severe duty" sked might help. I'd also suggest using NAPA Gold (Wix) filters.

In any event, I'd avoid Mouse Milk...

Many tests have been done with the various additives and the worst one to use is Two Stroke. It reduces lubricity.
Stanadyne is one of the best.

The Super Tech in the above post IS a good additive for older diesels but not all 2-Stroke oils are created equal.

Steve I was wondering when you were going to challenge this. I did post earlier that my VW mechanic added a quart of 2cycle to his recently acquired VW, before driving it home. It was about a 1000 mile trip. I am not really sure who to believe.

I'll see if I can find the link to the test comparison.

A small amount makes up for the marginal lubricity of ULSD. I add about 4-6 oz/30 gals. I'd be amazed if a truly independent test proved damage.

2-cycle oil is pretty much benign, since it's designed to be combusted. But there's no reason to overdo it. No more than a quart for a complete 100 gal fill up is plenty.

The addition is only to supplement the lube additives supposedly in ULSD.

For some reason I thought the ratio to add was A quart per 50 gallons of fuel. Only thing I dug up was the above. It was on this page.

I have been a diesel not since the early 80's. I used to add my used hydraulic oil to the VW and Mercedes a quart in 20 gallons when fuel had sulfur. I wish I still owned the old Mercedes turbo diesel. Some kind of lubrication is better than no lube at all. I have been using a quart per 50 gallons for 5 years now in my 3208TA Caterpillar engine.
