Personally, the only thing I (would) pour in my fuel tank is Stanadyne (purple) and the Motorcraft stuff they sell at the dealer.

 

I know people that only swear by Lucas... I personally use diesel kleen

Probably won't hurt anything but I prefer to stick to diesel-only additives if I'm going to use them. I've used Diesel Kleen, both white bottle and gray, for many years without issue. I've tried the Archoil fuel additive though it's hard to say if it did anything. I wouldn't hesitate to run the Stanadyne products as I've heard good things about them.

 

Diesel Kleen!!

 

I use Lucas in all my farm equipment, & it gives me more mpg's in our Explorer. It won't hurt your powerstroke but it doesn't handle water like Stanadyne, OptiLube, or others. You want to get something that demulsifies water, lubes injectors, and raises cetane.
Don't waste it like I said it won't hurt anything I just don't know if it'll help either. If nothing else use it in your wife's car

 

I use Lucas Oil. I notice no difference in performance or MPG for the truck, mini-van and car I use it for.

I recently started using Diesel Kleen in my truck in addition to Lucas Oil. I may get an additional 1 or 2 MPG with that. What I add to my truck for a 40 gallon fill up is one 16 oz bottle of diesel Kleen and one and a half 5.5 oz bottles of Lucas. If there is any gain, it is from the Diesel Kleen.

I add Lucas Oil to my vehicles because I will use these vehicles for six more years, and aside from regularly scheduled Maintenance, IMO a fuel additive is the only thing that may possible extend engine life. At worst, it does nothing bad to the engine.

 

When i change the oil i pour the used oil in my tank and top it off right away at the gas station down the street. never smokes, runs the same.

 

you actually dump 4 gallons of used oil in your tank, top it off and drive away?
no issues?

that some serious lubrication, even in a 40 or 50 gallon tank!

 

As sparkyF250 just said, one must remove the contaminants in the oil before running through the injectors.
I drain my oil in a 5 gallon bucket and it literally fills it up (I have a bypass filter). Then I put the lid on it (use the paint 5 G buckets, there a rubber seal in the lid) tightly; make sure it snaps.

My landfill which is a few miles from home lets me dump the oil for free.

I'm surprised you run your used oil in your engine without any kind of cleaning process. I think that's a good way to grenade an engine....I'm not taking that chance. Nope not at all not worth it to me.

 

I never heard of an auto parts store that cares or even checks what kind of used oil you bring in. I had a blown HG in a tractor engine and when I pulled the engine oil plug I got about a gallon of coolant before the oil. That went to the auto parts recycle tank >

 

you dont live in los angeles either. we are not allowed to park on grass or dirt. that law was passed in the mid 1990's. the aqmd says oil,fuel and wheel bearing grease will leak into the ground. a friend got a ticket for parking on his yard. we dont have a landfill thats open top the public. we have a trash dump for old furniture and wood type stuff. old electronic have to be taken to an electronic recycling center. we are not allowed to throw paint in the garbage, it has to be taken to a recycling cneter, but there isnt a recycling center for used diesel oil that my friends could find.

 

i didnt expect my injectors or other things to last 180,000 miles seeings how many others have had them and other things fail before 150,000 miles. i have thought about replacing the injectors before in make 3 cros country trips in august totaling 13,400 miles pulling a 10,000+ loaded trailer 6000 of those miles. i will decide in the next month weather or not to replace them. i dont want to be in the middle of nowhere in texas on I-20 at night and have an injector stick open. in the daytime its easier to see under the hood to unplug the bad one and hope it stops shooting gas. i call diesel gas, i got gas. and i dont want to stay in a motel room for how ever long while its gettin fixed.

 

There is a whole lot more to life than salary.

I just realized I've got about two tanks of fuel sitting in my back yard in T6, Delo and Premium Blue jugs. If I through in the Castrol and other misc jugs, I've probably got three tanks. Well, I guess I should cut it at least a little with diesel.

 

I have a sweet set up, a buddy of mine has a waste oil furnace and he brings me a 55 gal drum, when it's full I give him a call and he brings an empty and takes the full one. Beats taking it to the auto parts stores.

 

I love the dumping the oil in the Mayors yard.

The 2 Stroke oil is a low ash oil that's meant to burn. The straight oil is not going to be pretty going through the combustion process. I still remember when good ole California came up with the great idea of a $1.00 a gallon excise tax on used returned oil. The truckers were just dumping it into the fuel tanks. You could follow the black trail of smoke 1/4 mile behind them out of both stacks on the highways.
Governor Wilson I think is who passed that one. It was repealed less than a year later because of the smoke on the highways. Was not illegal to burn it as a fuel and would have been too much work making it illegal. So they scrapped the idea and taxed us on something else I suppose.

Don't burn your oil there's nothing good to come from it.

 

I have to say something about returning used oil at the parts stores. I have never heard of not accepting oil from diesel engines.....??

I live in the same damn state and I bet I return 15-20 gallons a month from doing service on diesel engines for fire pumps. Not once have I been asked if its diesel ol or seen anything stating they won't take oil from diesels. Hell they know the oil I'm returning is from diesel because they sell me the filters and oil.

Never heard of that, not any of it...........man this is a crazy thread.

Oh and theres trucks going 400,000 miles on the OEM injectors with regular fuel and good maintenance.

 

We usually have trash piles from clearing or cleanup that much of our used oil helps burn, but we do have other collection places we use too. I don't think it's truly detrimental to the engine to run low doses of used oil through the tank as long as it's clean and well filtered. If I were going to do it, I wouldn't put all 4 gallons in at a time though. I wouldn't put more than a gallon to a tank. I do use a mix of TCW3 and Diesel Kleen when I fillup. About a 3:1 mix and I only put about 8 oz. per tank.

 

I'd like to see a picture of both fuel filters. Mine usually look brand new when I change them. Looks like there's a lot of junk floating around in the oil.

I kicked around the idea of recycled oil, but the centrifuges and mods to the truck were pricy. I even thought about getting an older diesel with a mechanical fuel injection to do this, but would not make the money back in free fuel.
