Does anyone add 2 cycle oil to their diesel fuel? Pro’s and con’s.

Thanks

I'd much rather run something that's more tailored for that, like Lucas Upper Cylinder Lube.

In our old 5.9 we use Opti-Lube XPD additive, 1/2 oz per gallon of fuel.

Outboard 2 cycle the basic stuff is perfectly fine to add to the pre 07.5 Cummins engines. Heck a quart per tank of your used engine oil is perfectly fine also.

They are called "Oil Burner" for a reason!

When I had my 7.3 , I used the recommended Two stroke that stated it had TC-W3.It was rated great for lubricity which the current diesel fuel doesn't have. All older diesels should use this.

Nope, never have. Thought about it, but never did it.

2 cycle oil is designed to burn as cleanly as possible. It shouldn’t hurt a diesel in moderation.

I’m not sure how it likes being compressed to 35000 psi’s in a common rail fuel system.

The manual for my old mechanical diesel Land Cruiser says emergency fuel can be made from 3 parts gasoline to 1 part 30 weight engine oil if necessary. It was built before the internet so that could be danger danger now.

I put a pint in with every fill up in my 2007 6.7!

I read on a diesel forum, where an extensive test was performed using many fuel additives and conventional 2 cycle oil. The 2 cycle oil fished in 2nd place to a high dollar additive. I can’t swear that it helps.....but, I bet it doesn’t hurt!

In fact, as embarrassing as it is to admit this. About 3 years ago, I had my head placed securely where the sun doesn’t shine, and in almost 30 years of driving diesels.....I finally put gasoline in my diesel truck. I didn’t realize what I had done until it was full. About 27 gallons of gasoline in a 34 gallon fuel tank! 19 miles to my house, drain fuel tank, put a few gallons of diesel with a gallon of 2 cycle oil in tank and flushed system to injectors. Drive to town, fill tank with diesel this time! About 40K miles later.....she’s still doing OK. I can’t help but wonder if that little bit of 2 cycle oil added may have helped some! memtb
