Adding oil to fuel (1 Viewer)

[Bandit_guy]

Has anyone ever done this or knows anything about putting oil in your fuel tank to help lubricate the engine ? I was chatting with an older gentlemen who has had diesel trucks longer than I have been alive and swears by this. He said since Canada has just begun selling the low sulphur fuel it's more important than ever to keep things lubed up. Half a litre of engine oil or even 2 cycle oil to an 85 litre fuel tank was what he recommended ?

Any knowledge on the subject would be greatly appreciated.

There have been threads mentioning this in the past. You can use search to read them. I have also heard about adding tranny fluid to your fuel. Personally, the only oil I would add to my fuel is veggie oil. Engine oil has all kinds of additives you really don't want coming out your exhaust.

I always add something to each tank ,usually diesel treat type stuff but also veggie oil and I have tried tranny fluid too,concerned ref low sulpher fuel and lubricity

Sounds like a good way to git rid of the used oil

I have 3 five gallon buckets of waste oil from various fluid changes, I wish I could just burn it away, but my opinion is that I'd never be able to get it clean enough (filtered, dewatered, etc) to want to run it through my IP and injectors.

I've added 2 stoke oil lots in the past.
I wouldn't add just any oil, used 15-40 or ATF etc. 2 stroke oil is engineered to burn in the combustion process and not coke up the small 2 stroke motors, so it's not likely going to create any problems in a cruiser diesel.
The VW diesel crowd swears by it... at least the earlier VW dieselers... 2 stoke makes the TDI crowd nervous with Cats and EGR and all..

Mine seems to burn oil by design. Without a catch-can, oil is getting burned anyway. It's just not going through the IP, only the intake and cylinders.

I know, not what you're talking about...

X2 in the 2 stroke oil ..

 

[Bandit_guy]

I get the 2 stroke oil concept, I'm not sure about it being the best way to get rid of the old engine oil . So what ratio of oil to fuel. In my outboard I put 100:1 I thinking less oil for a cruiser ?

Whats the proven benefits of adding oil to the fuel?
I know of owners with 700000 klms on their 1HZ and they have never done anything except regular maintenance

if you want to burn waste oil cheeck out threads on black diesel there on mud and all over the internet
but i'm not really willing to try it

nice read here.

I'd love my cruiser smelling like Castrol A747 but that's freakin expensive I just use outboard 2-stroke oil as in the read, I sometimes think it makes the engine slightly quiter...

Thanks for the link Dutchie, I read it about a year ago and was trying to find it again to put in this thread.
2% biodiesel really seems the best, and cheapest route, if you are worried about ULSD.
I use PRI-D as a stabilizer and regular additive and it works great for me....

x3 on the 2 stroke.... I wouldn't be afriad to run 10 or 15% SVO either

Used engine oil can be acidic, that's why it isn't often used as undercoating either. Not to mention the issues with the environment...

I have a bunch of mineral based two stroke I use, just mix it like 200 to 1, and a little SVO

I think you guys are being overly confident in thinking that 2-stroke oil doesn't leave carbon deposits, it does. Here's a pic of a 160cc mower motor I did a couple of weeks ago. Unfortunately someone distracted me when I was about to take the "before" shot and I forgot to do so so can only show you the after shot.
The top vertical notch on the exhaust port was completely blocked with carbon (polished by piston so at a glance if you didn't know what the ex. port was supposed to look like you'd miss it), the main part of the port about 25% blocked. This stuff keeps building up until the motor refuses to start. Yes 2-strokes do run a much higher oil mix than what you guys would put in your diesels so you will have to do some math in determining amount of build up. Total run time on this motor is probably less then what you would do in a year in your cruisers. Having seen a few coked up 2-strokes I would never put that stuff in my tank.

Owned a few 2 stroke bikes, terrible for fouling plugs. The kwaki 750 triple even has a spot under the seat for a spare spark plug. 2 stoke runs dirty. That's why i stick with Howe's, because it was designed to work with ULSD. probably cheaper than 2 stroke oil anyway, one $12 bottle treats ~750 gallons. less than 2¢ a gallon.

 

[sandcruiser]

motor oil in the fuel seems silly to me. and dirty.

besides: the hd-t in stock config pulls plenty through the valve cover into the air stream anyway

you can burn any thing that is made of oil with diesel regardless of that they are made of other none filtered veggie oil cause they do not mix up well with petroleum based product. I had been buring, power steering fuild, ATC, 10 x 40, 20 x 50...whatever and my 3 B just burns it. Also the two cycle oil is very much the same as 5w oil do not waste your money on it.

Remember that Injector pump and injectors need internal lubrication and none lubricated diesel fuel will mess them up over time.

 

[rockcrawler]

Personally I would not put any oil in my fuel, that it burns is actually the problem. You're not just talking coked up combustion chambers, blocked injectors, build up in piston ring grooves that can lead to piston rings breaking... it also circulates through your whole motor causing wear as its an extremely hard substance.
