dazbrit Posted September 5, 2013 Report Share Posted September 5, 2013 At the garage this morning I managed to put just over a litre of petrol in my car (Discovery TD5). The tank had about 20 litres of diesel in when I did it and I put another 30 litres of diesel in after to try and dilute it so the mix is about 50:1. Will this be ok? Will it cause any damage? I've been told so many things, truck drivers put petrol in when it's cold, it cleans the engine, it should be diluted enough, but also been told to drain the fuel as it damages injectors, turns to a glue like substance, affects performance etc. so wonder if any of you guys can help me out. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
aga man Posted September 5, 2013 Report Share Posted September 5, 2013 (edited) i would of thought such a small amount wouldn't affect anything. carry on as normal fella. {i'm not a mechanic by the way} Edited September 5, 2013 by aga man Quote Link to comment Share on other sites More sharing options...
Matty7247 Posted September 5, 2013 Report Share Posted September 5, 2013 My friend did this, filled his 300Tdi Defender with petrol, after it was drained, they said it would clean everything out, but said to do a fuel filter change after a tank of diesel. You should be ok. Quote Link to comment Share on other sites More sharing options...
robbiep Posted September 5, 2013 Report Share Posted September 5, 2013 You should be ok. For the next few tankfuls, don't let it get below half-full before topping up to full again. That way the petrol gets diluted as much as possible. Quote Link to comment Share on other sites More sharing options...
phaedra1106 Posted September 5, 2013 Report Share Posted September 5, 2013 Just to be on the safe side I'd syphon off all the fuel and give to me, that way I'll take all the risks for you Seriously at the mix levels you're talking about it won't be an issue Quote Link to comment Share on other sites More sharing options...
mick miller Posted September 5, 2013 Report Share Posted September 5, 2013 Did this in a Passat, no drama, just keep the tank as full as poss for a month or two and change the fuel filter a little earlier. The other way round however... Ouch! Quote Link to comment Share on other sites More sharing options...
neil3728 Posted September 5, 2013 Report Share Posted September 5, 2013 Putting petrol in a diesel tank is not so bad. Its the other way round that will kill an engine, thats why diesel, nozzels are lager than petrol cars. On such a small mix you will be fine. But as mentioned above if you are worried i'll take it off you my 300tdi will run on it no problem. Quote Link to comment Share on other sites More sharing options...
markreed Posted September 5, 2013 Report Share Posted September 5, 2013 That won't pose a problem it might just run a bit warmer but should not be enough to burn the injectors, I put £30 in my terrano on top of 1/4 a tank a couple of years ago I drove 11 miles home and the penny dropped I had for some reason put petrol in, I had just got rid of a petrol disco 3 , I syphoned it after a lot of messing about then put £100 in diesel , drained the filter no problems..

leeds chimp Posted September 5, 2013 Report Share Posted September 5, 2013 Should be OK with that amount really Quote Link to comment Share on other sites More sharing options...
Disco Stu Posted September 5, 2013 Report Share Posted September 5, 2013 I wouldn't worry at all if you topped the tank up with diesel. I sling left over bits of petrol out of my bikes in to my diesel car a couple of times a year then top up with diesel, never had any problems.

Tommo Posted September 5, 2013 Report Share Posted September 5, 2013 Keep filling full of diesel to dilute it. My Hilux runs on 20% Derv, 85% veg oil and a litre or two of petrol. It's a diesel just in case your wondering It should be fine - Quote Link to comment Share on other sites More sharing options...
dazbrit Posted September 5, 2013 Author Report Share Posted September 5, 2013 Thanks for the replies. Just been and filled it up with diesel and now my wallet is not looking too good. Hopefully it will be ok now and I'll be more careful in future. Quote Link to comment Share on other sites More sharing options...

Went for a couple of years and weighed her in cus she needed a fuel filter. Karpman Quote Link to comment Share on other sites More sharing options...
rwade545 Posted September 5, 2013 Report Share Posted September 5, 2013 My merc e320 diesel was completely dry, fuel warning on, put 20 liters of petrol in, drove it 40 miles home ( after night shift and had been using misses petrol car before). Sounded very ruff, which I thought was exhaust. Finally figured out what I had done, kept it brimmed with diesel and it sailed through mot a few months later and was non the worse for it. ( German engineering for ya and I didn't fancy dropping the tank out and flushing whole system which I was quoted 2k to do). Such a dilute amount should be fine, petrol and diesel both come from the same crude oil. Quote Link to comment Share on other sites More sharing options...
