Spoiled by my wife's electric Mini, yesterday I put 14 litres of unleaded into my 2003 TD5 before realising the error of my ways...
After some discussions with the pump manager and my garage I decided to fill the remaining 36 litres with diesel. I then drove home and it seems all right... Planning to top it up asap with more diesel for a while... Do you think I should be all right? Thanks Alex http://instagram.com/h4vou/ |

When I was a student (20+ years ago), I had a delivery job and filled the diesel tank up with unleaded. I managed to get to where I was going but it wouldn't start. I had to syphon out the petrol and my boss turned up with 20 litres of diesel and a new filter. The van was fine afterwards, I couldn't go near naked flames for a week though.
A boss at another job, put petrol in his diesel tank but stopped after about 5 litres and realised his mistake. Called his recovery company, the mechanic who came out told him it would fine if he filled it up with diesel and didn't let the level go below 1/4 full. He also told him that adding petrol to diesel used to be a thing for diesels when the fuel would congeal during the colder winter months. A quick google: If you’ve added more than three percent petrol to a diesel car, you may experience decreased engine performance, stalling, and possibly even engine damage. In this case, it’s important to get the car checked out by a professional mechanic to determine the extent of the damage and whether or not the car can be driven. You are currently sitting at around 28% petrol in your diesel. https://www.rac.co.uk/drive/advice/know-how/wrong-fuel-recovery/ https://www.theaa.com/breakdown-cover/advice/wrong-fuel-advice Craig. “Don't believe everything you read on the internet.” ― Abraham Lincoln www.scotgrc.co.uk |

I’d imagine a TD5 would be absolutely fine after that. Hardy engines. 2008 2.4 110 Utility Station Wagon XS.

If I could I would drain and replace, alternatively put a good slug of quality 2 stroke oil in to add some lubricity DEFENDER 90 TDCI XS,

Just keep adding diesel. The more you add the less % of petrol. Carry a spare fuel filter just in case, and change soon too.

Keep topping it off with diesel and it'll be fine

I’d be draining asap, it’s lack of lubrication in the hp fuel pump and injectors that would be the worry 2015 RRS Autobiography SDV6

The injector on a Td5 is the pump as well, with only reciprocating movememt. Was it any other engine, Landrover or Ford, with a rotary injection /HP pressure pump, lubrication could be an issue, although I doubt with a dilution of 23%. 1988 90 Hard Top, 19J Diesel Turbo, Shire Blue - Restoration ongoing

Drain and replace before you kill the old girl.

Drain it as much as possible but keep the contaminated fuel, brim it with diesel, but thereafter add a small amount of the contaminated fuel to each new tank full. Saves wasting fuel, plus many an old HGV driver will tell you about adding petrol to diesel to help stop diesel waxing during cold winters back in the day Jumped ship to reliability - Mitsubishi L200

Don’t understand this bit. Spoiled?? Mini?? Electric?? Wash your mouth out. You can use super unleaded, or diesel for this. |

"...many an old HGV driver will tell you about adding petrol to diesel to help stop diesel waxing during cold winters back in the day"
BIG difference between "back in the day" engines and today's direct injection. My boat was filled with diesel which came from a supply so water-contaminated that its Volvo (Perkins-based) engine simply died. Flushed through, filters changed, absolutely fine. A more modern-designed engine would at least have needed a strip-down, and nobody intentionally adds petrol to diesel. In the OP's situation I personally wouldn't worry too much. The engine's running fine, and every diesel top-up - I would use "Super" diesel though - brings the mixture back to normal. Peter |

Mrs did this to our two week old disco 4. But put significantly more than that in. Topped it up and drove it. Kept it for another three years. Don’t know where it is now or if injectors or pump failed after that

If I were in your position and I was going down the keep topping up with diesel to dilute route (I wouldn't let the tank get below 3/4s for a few weeks) I would also throw in some two stroke oil to protect the pump fuel system and injectors.
