Oil for diesel additive

[zagarus]

Ok so i figured i'd try something else as an additive and i know some people have mentioned 2 stroke motor oil. Well i was looking for some then i came across somethign else.

Quaker State "Q diesel plus" synthtic blend.

Its for VW passenger diesel vehicles and its a 5W-40 SAE oil.  I was wondering if this would be alright to add to a full tank of diesel and if it would benefit by lubbing up the fuel system.

Anyways before i put any in my car it would be much appreciated if any of you have any insight into if this is a good idea or bad idea, to be putting in my fuel.

why waste a perfectly good motor oil in a tank of diesel though??? i've heard of people using their waste oil after doing an oil change before, but thats all.  two stroke oil is probably a really good choice.  power service makes a pretty nice additive!  try it out.

i wasnt sure but it was only 10bux so if it can get me 200 km extra with it (not the whole thing in a tank at once) then it would be worth it


but you suggest 2 stroke eh, thanks.

that synthetic oil should not combust.  it may combust slightly, but not much...  it will lubricate certain pieces in the pump, but only to a certain degree.

you will most likely see 200km's extra by adding power service diesel fuel conditioner in the right dosage.  boosts the cetane number so you don't need to hit the pedal as hard, has anti-gel, and lubricates the pump.  a bottle is around $18 here at cdn tire, and lasted me a year, although i don't do many long distance journey's...

i have been using a cetane boosting additive, but im still only getting like 36mpg tops.

Stanadyne makes some good additives. I'll try to find some info.

The thing about synthetic oil is that it has a higher film strength than regular oil, which is one of the reasons it protects better. There are synthetic 2 stroke oils, which can usually be diluted more due to that fact, but they cost. I think MC-1 is $12/quart. I would always run synthetic in my jet-ski and bike and dilute then 50:1 rather than the recommended 32:1 and never had a problem. I could see it helping the pump last. Wal-Mart used to sell a gallon jug of synthetic fior a reasonable price.

Castrol has a synthetic outboard 2 stroke motor oil at walmart for ~$15 for 4L IIRC.  That should last a long long time for most people.  I do find if I mix it too heavy I get a small puff of blue on start up in the colder weather, other than that no additional visible smoke when up to temp.  I put it in with my powerservice jug and mix the two 50/50 then I add ~80-100ml of the mix to the tank that gives me about 1100:1 if I got my math right for my tank size.  I don't think it hurts, anything to stave off another pump :evil:

Although cetane and lubricity are both important, it is currently lower fuel viscosity and it's effect on the dynamic timing advance that causes the poorer fuel economy.

hehe so time to raise the viscosity!

anyone remember what i said about the million litres of diesel wayyyy up north??? I CALL DIBS!  Canadian government wants that stuff GONE... but then again, its not low sulphur diesel...  

only catch is... there are no roads there.  :lol:

[jerrydog411]

why not simply mix in some biodiesel?  a little higher viscosity, great lubricity and it burns.  a little less crap in the air too.

They have quite a bit of additives. They are like bosch because the make pumps too. I have heard many good things about their product.

[jtanguay]

would be such an asset to be able to adjust a pump via the viscosity of the fuel being run through it.  is that what the piezo timing would be for? kind of like the one on the no. 3 injector on TDI's?

[jasonsansfleece]

I reset the internal pump pressure (it was low) and it made a positve diference to how the car runs.
Search the vwdieselparts.com fourm for how to.

Go to any truck supply shop. You can get a case of good additive for very cheap.

Use the DBF-4 from PROLAB!
Why use anything else then the best stuff. At only 20$ for 1L that treats 2000L... .01$/L of fuel, it's definitly the cheapest! There are test made by ITAQ saying that the Jetta save 14% on Fuel using the DBF-4 from PROLAB-Technologies. It's the best on the market, also if you never want to have any problems with the whole fuel system. It cleans, lubricates the pump, eliminate water and it's not "oil base" so, environment friendly and it burns clean and biodegradable.
