Fuel Additives

Just curious if any of you with old Detroits run additives in their fuel? If so what kind and why? I run it in my older diesel tractors as it is my understanding when they took the sulfur out of the fuel the lubrication of fuel pumps, etc was reduced. Most of the owners around me with old Detroits and MANs use Lucas oil. I have put it in my first tanks as the fuel was old and have mixed it with the fresh fuel I have added. Now that I have burned most of the old fuel out just wondering if I should continue this. Im not speaking of biocides but the additives that are supposed to clean injectors, stabilize fuel, etc.

I've used Schaeffer 2000 for more than ten years and the last three I've owned Aslan. Why? Why not?

Yes, you need to use additive for lubrication. Cleaning agents are a nice side benefit. But for "visible", measureable results you'll want one that boosts cetane as well. The fuel quality today is terrible.

Old time mechanic recommended that I use the Lucas additive also and I do add every time I add fuel. John

I use DieselKleen. On my last trip North to South, my fuel consumption was at least 10% better than the prior trip, apples to apples, as best I could tell. I really like this stuff.

North to South, that’s downhill ain’t it?

I may swap to the Diesel Kleen. I dont see on the Lucas where it is a cetane booster plus it is $30 to treat 400 gallons. Diesel Kleen gray can is $55 at tractor supply for a can that will treat 1200 gallons. It has cetane booster too. I use it in my tractors and equipment. They all claim to improve economy but there are so many variables offshore I doubt I would ever realize anything there.

Robert I havent seen Schafers in my local stores but I used to drink Schafers Light back in the 80's. It was a step up from K&B beer.

What do you mean Quality is low I have read on this forum that diesel last forever ;)
Just filter it good and run the shit out of them :cool:

I used what Detroit specifically recommends : nothing. If the boat is going to be stored and not used for a long time, they say use some Biobor

Read their fuel specifications and you will note they are looking for as LOW a sulfur content as possible.

Not true.

5hey called for lower than 500 ppm. Today's low sulpbur fuel is coomed tonremove sulphur and in the process lowers lubrucity. Detroit ztates if lubricitybdrops it can be replaced with additive. They call for under 500 um scarring or add lubricity.

You'll read a lot of things on this forum. Like the post that followed yours. While that was true in 1980 it's not true today. But that's okay. It's good for business.

I'll dig up the spec when I get back to a computer. I'm pretty sure you are wrong as I read it many times and good DD guys confirm it . Besides all modern diesel fuels have lubricity in the blend.

Its not like it was and things change :confused:
Fuel is different today then years ago I wish someone told me to read what I wrote years ago.
But then again when I first posted that E10 was eating the fiberglass tanks I was asked for the tests results. Many challenged that info but decided to leave the forum be fore they said hey you were right.
This reminds me of some that think slug in the bottom of a diesel tank is to be expected which reminds me I need to change my filters they are 3 years old so I feel guilty that Racor is not getting the proper funding from me :D

Here's another copy of the test results in case you ever need them again ;-)

Ditto on ALL that. BioBor only AND none of that other crap!
