Low sulphur fuel

[Toronto]

So here is the question. How well will our 80's, 90's DD run with the reduction of sulphur in the fuel?
It's a lubricant and they just removed most of it. Do we need to be concerned?? Toronto

They add lubricity enhancers to the fuel but you can add more. I use Power Service Diesel Kleen as its sold just about everywhere and the price is reasonable.

There was a good thread on this subject last week. I use 2 cycle 2cw3 oil. 1 gal per 200gals of fuel.

I just started running 2 stroke oil after reading that thread, I added a gallon per tank. Just make sure it has no ash in it.

I missed the thread. Can you post a link?

Sky - I too have been using the Diesel Kleen - 1 gallon per 100 gallons of diesel - what mixture ratio are you using?

I'm by no means an expert on the subject, but did do quite a bit of research prior to deciding on 2 cycle tcw3 as the additive of choice for my situation.

From my understanding diesel kleen is primarily a fuel system cleaner. It cleans deposits from injectors and injector pumps (which detroits do not have).

It does appear to have some lubricating qualities but is not the primary purpose of the product.

Generally speaking our old detroits do not suffer from becoming 'dirty' or clogged fuel systems b/c we have 2-3 filters upstream of the engine that seem to handle any junk/gunk that can clog an injector.

While i do not think diesel kleen is bad or shouldn't be used I do not feel it completely addresses the lubricity issues caused by low sulfur fuel.

If you want to use diesel kleen I believe I would use an additional additive for more lubricity.

Do modern four-cycle diesel engines need additives when you are operating them on low-sulfur diesel?

I use DK in at the recommended dosage in my boat, my truck, and all of my construction equipment at the quarry. We've used it ever since ULSD came out with no fuel system issues on any of the equipment.

I really don't think this lack of lubricity is much of an issue. Do you ever hear of any truckers complaining about failures? If it was truly a problem we'd be hearing about issues by now.
