Unleaded in diesel???

Chucked 20 litres of unleaded into the tank last night in order to top it up before long drive tomorrow (now not happening) and then drove 3 k's home.

Realised mistake when got home. Stoopid!!

Car is an Australian delivered update E53 3.0d.

Anyway, baring in mind that the car would've used max of 300mls of fuel on the trip home and most of that I'd hazard a guess would be pure diesel which was already in the fuel system -my question is.....what damage if any could've been caused by 3 k's of 20% diesel mix??

Car is being towed to garage tomorrow for a tank drain and new fuel filter tomorrow......

What are your thoughts?? Any other precautions I should take?? Bills I should expect???

Since the diesel E53 wasn't sold in the USA...you may need to depend on those from other parts of the world to comment...unless some have knowledge of diesel engines or own other models/cars that are diesel. Until that time, I'd do a google search...or check one of the other forums that use the M57 engine. Good luck.

EDIT: just typed "what happens if you mix unleaded with diesel fuel" into a google search box and got this result at the very top:

My neighbor drives a GM Diesel truck. When things get cold he often dumps some regular unleaded into the tank to help keep the oil fluid. He was an O.T. R. trucker for many years and that is what they did in colder times. I do not think it will be a big deal and not near as bad a diesel in your gas tank. I had a fill up once and they had by accident mixed up the the tanks for the pumps and filled the gas tanks with diesel. NOT GOOD!

I am a Diesel mechanic by trade,
Putting 20ltr of reg on top of 60ltr of diesel, Yes it would make it a bit thin, But as you say it wouldn't have used that much fuel in the 3km and most would be pure diesel, As a precaution I would put some Stanadyne Fuel Conditioner into it for a bit of insurance,
IMHO I would put this stuff into it on a regular basis It helps the lubricity on low sulfur diesel, Also when I run engines on the Dyno it improves eng HP (not by much)

Thanks for the replies guys.

I wound up having the tank drained, fuel lines blown out and new filter chucked on.

There was no evidence of damage and she appears to be running as well as always!!!

As an aside, due to the time of year and all indie shops seemed to be closed for Christmas, I had to take it to a BMW dealer.......... Ouch.

In good news my insurance company is picking up the tab (minus my excess anyway).

It'll be a self rectifying error all the same!!

Hello,
X-ray- Lima, don't worry at all! Due to short distance- around 3 km, U made no damage to the engine. In the extreme winter situation, when the temperature is well below minus 15-20 degrees C, it is recommended to add some petrol, less then U did, though...just to prevent separation of paraffin from the diesel fuel...
Bearing in mind that in my country (Bosnia&Herzegovina) we cannot rely on the constant high quality of the diesel fuel on every gas station, it is a common thing that for every full tank of diesel (90 liter), we even add 5 liter of ATF (brake liquid) !!!! Just to prevent the above mentioned separation and as a sort of a maintenance of the diesel hoses (more than 500 EUR per piece!!!).
I am using Castrol Diesezusatz TDA Systemreiniger ( http://www.castrol.com/castrol/gener...tentId=7038739)... 10 ml/1 liter of diesel fuel... works fine!

Sorry, some correction is needed- ATF is not brake fluid, but automatic transmission oil..

Good outcome for you X-ray lima. I have just purchased a diesel X5 and have wondered what would happen if I did the same thing after 40 years of driving petrol cars.
