Adding Oil to Fuel????

[whitetmw]

Got a call today from a friend who said he was fueling his Truck in Southern Virginia and the Mechanic said he was suggesting owners of older (2006 and prior) to add a quart of oil to the fuel when filling up. Said the Low Sulfur content has reduced the lubrication abilities of the fuels since 2007. I told him not to do any such thing. But, said I would post it here for input.

I occasionally include LUCAS or another brand of treatment occasionally to keep the system clean as can be.

Question: If this bulls&#t or what?

I add an additive due to my engine telling me it sounds quieter.
SOOoooooo when are we gonna get a choice at the pump like gasoline burners do?

I've never done it, but I've seen a few posts about adding 2 stroke oil to the fuel, or a product like DieselKleen... I just bought some of the DieselKleen a few days ago, gonna try it, see if it changes the idle chatter and ease of start up, and also the fuel mileage...
I would guess that the type of oil would make a diffrence, I hope others who know more than me will advise...

I haven't tried it but i have read every thread on it and the people who do use it swear buy it but there is a ratio of 1oz to 1gal and it has to be ash less two stroke which is marine two stroke.

I'd check out the numbers in this post before I started pouring crap into my tank.

I add 1 once per gallon(2 stroke ashless) every other tank.It does quiet the motor down alot,nothing much on the mileage to speak of.

i do one ounce per gal. of TCW-3 2 stroke outboard oil. it has to be marine ashless if it says TCW-3 your good to go. it runs better and makes it a little quieter

If you do add oil it has to be ashless 2 stroke oil. Any other types of oil will cause injector damage. It has been known to quiet the injectors. But not much if any fuel mileage increase

Perfectly said I ran Diesel Kleen for a long time to increase lubricity. But switched to TCW3 for cost. (I am a boat dealer). If I have to choose and both were = priced. Diesel kleen would be my choice.


So there is partial truth to what the mechanic said. The ULSD was little lubricity and can use some help. But adding oil is a bit much in my mind. Will it burn? YES. Can it clog or damage injectors? YES.

A friend of mine has run around 30-40% used filtered motor oil when the fuel prices were real bad. I wasn't that desperate though...
