Diesel Engine Oil

Guys, I know you're all laughing, but something really bad has happened to me.

I refueled my friend's truck at the transport company. There were two fuel pumps standing around, unlabeled. I put the nozzle in and started pumping. Suddenly, my friend appeared next to me and shouted 'Stop!' I had just put the wrong fuel in, and I had put 2 liters of diesel instead of diesel.

So, I called a friend who used to own a gas station and is also an auto mechanic. He said I should add 70 liters of diesel to the tank and drive carefully, refilling immediately whenever possible, so that the mixture is diluted.

I did the same and was able to drive comfortably 25 km back home.

Just this morning, I'm having some doubts.


shouldn't I rather drain the mixture instead?? or does the engine/fuel pump do it???

Well, it's a VP and 2 liters of oil mixed with 70 liters of diesel, I wouldn't drain that now. Back then, they used to add some oil for "lubrication." I wouldn't worry about it. My uncle once filled his AFN with 4 liters of Super fuel, and it still ran without problems afterwards. Of course, he also immediately refilled the diesel.
What kind of oil did you put in your car? I consider motor oil to be unimportant, however, the general term "lubricating oil" seems to me to be too broad.

Thank you for the quick response.

it's engine oil for the LKW's. I hope for my engine, that you are right

But I would also be interested in hearing other opinions on this.

So, if it's just a {MÖL}, then it's absolutely no problem.

2L MÖl on 70L Diesel is not much.

Some people add an extra few liters of oil to the tank to protect the ESP.

You can therefore drive and sleep well without any worries.

Best regards, Georg

I agree with GeorgTDI. It is absolutely not critical. Maybe you're even doing the ESP a favor.

Hello!

Thank you very much!!! That already makes me feel much better!!! And especially, thank you for not laughing at me immediately!! It was so stupid, but also...

but I'm already quite optimistic that the engine will survive!!!

So, if it's engine oil, don't worry, everything will be fine, the engine won't be damaged.

Well, (Oil) Additives can also have unsightly side effects - especially in the long run -> Search.

But because one tank of fuel with approximately 3% oil content would not cause me sleepless nights

I have some truly amazing news to report!!!

Thankfully, it's exactly as you said!! There are no negative effects from the oil, no jerking, smoking, or anything like that.

I had a problem with our bus where, suddenly, it was consuming around 10 liters per 100 km, especially during the last few kilometers. We were planning to take it to the workshop.

I was just at the gas station, and I checked the numbers. It says 5.93 liters! Is that even possible? Maybe it's just my mistake and the oil level, too. I'll just keep an eye on it for a while.

That's good news

Perhaps the whole thing could be explained like this:

*Hypothetical mode activated*

Perhaps the lever in your ESP was very stiff and often stuck at the end. This could result in your fuel consumption increasing to up to 10 l/100 Km, depending on the load.
When you added a few liters of MÖl in addition to the diesel, it benefited both the ESP and the injectors. The ESP valve now functions properly, leakages are smaller, and the injection pressure has increased accordingly. This could potentially explain your fuel-efficient 6 l/100 Km. Unless another, independent error was still in play.

*Disbelief mode*

Hello everyone

@th3_fr34k, I'm currently using a mixture of 0.25 liters of two-stroke oil per 50 liters of diesel.
The engine is a 1.9l VW TDI. I can also confirm that the fuel consumption has been reduced. This amounts to almost 0.4 liters per 100 km.

Second-stroke oil, because it is self-mixing.

So far, no problems, neither with the engine nor the heating system.

Hello,
but what does the catalyst say to the oil in the fuel?
Best regards,
Günther

Hello Günther,

Self-mixing might be better expressed as 'it tends to dissolve in the diesel' instead. So, I can no longer be separated from the diesel fuel.

At a 1:200 ratio, this probably won't make a significant difference. I would also say that the two-stroke oil will likely burn more readily, just like diesel. So far, there haven't been any noticeable smoke clouds, at least it doesn't seem like a 2-stroke engine.

Does the Oxi-Cat somehow get involved? ? ?

I was just wondering if it really is possible to save a significant amount of fuel with it.

Mileage measurements have also remained the same.

hello

Werner

Also, ich denke, ich werde einfach etwas 2-Takt-Öl in meinen 1.9 TDI Audi 80 einfüllen, der unerklärlicherweise einen zu hohen Verbrauch von 8,5-9 Litern hat. Es wäre wirklich lustig, wenn es etwas bringt

That's impossible!
Here's a basic reason why a TDI with oil contamination might run more efficiently:

{REASON}


Maybe the oil hasn't yet revealed all of its undiscovered energy within the diesel fuel and is releasing it!

Hmmm,

Possibly reduced leakage losses, while still ensuring the lubrication of the pump internals?

hello

Werner
