Petrol in a deisel

[kugs330]

Hi guys went to fill up my toyo d4d on Friday I told the attendant to fill in diesel while I was checking the tyre pressure, when I noticd he was pumping in petrol :RedNo: I stopped him but he had already pumped in 10litres of petrol, it was late in the afternoon and the managers were not there. After 30 Min of waiting for the supervisor to try and find someone to come and drain my tank I decided to top up with diesel (61 LITRES ) I've done 236km since Fri with no issues , do you guys think I need to drain out tank and flush lines or run bakkie with this mix ?
I've had this issue a few months back but only realised the mistake after driving for about 35ks then bakkie started missing and losing power I switched off immediately and had aa tow it home were we drained out fuel and replaced fuel filter did about 6000km since without any issues.

I know some old-school mechanics who would mix the two to "clean" the engine (whether it works or not...), but it's definitely not something you want to do very often . You've already driven a fair amount with it, I'd say fill up again with diesel and then run this tank empty.

from my limited knowledge, and what I have read on these and other forums

Diesel engines can run on petrol
Diesel requires higher compression to reach ignition/flash point, so petrol will ignite a lot easier
Diesel is a very unrefinned version of petrol, so alot more particles still left inside. petrol will actually burn cleaner
Diesel is very "oily" and the diesel fuel and engine components are lubricted by the diesel fuel, Petrol on the other hand has very little lubricating properties compared to diesel
Running petrol will cause loss of fuel component lubrication and higher combustion temps
I have heard of people using Petrol and adding diesel oil into the mix to restore the lubricating properties, and to lower the combustion temperatures

all the above is what I have read on these and other forums, and have made up my own opinion....not the Gospel

it'll be fine.
throw some liqui moly super diesel additive, some wurth diesel purifier
etc etc and you should be good.

and yes a bit of petrol with the diesel is a well know oldskool "clean"...

did you know you can run a diesel engine on transformer oil?

Thanks guys will run her a bit and see how it goes was reading on some overseas forums and guys talking about replacing injectors , pumps etc :thumbdo: My dad used to fill some petrol into his old Toyota hilux back in the day used to give it a bit more power on the hills R5 petrol and R50 diesel full tank :roflol:

yeah, the ratio is around 10% or less. i think if you bomb the tank with those diesel additives/products you will be fine.

:withStu: you have nothing to worry about.

the key is in the ratio.. a diesel is a compression ignition engine, adding petrol to diesel will make it easier to ignite and and more rapidly burning..

so with too much petrol mixed with diesel there is no controlled burn when fuel is injected into the cylinder, and cylinder pressures peak far beyond what the internals was designed for..

also the diesel itself lubricates the hp pump and injectors, loose to much lubrication and problems..

1/10 mixture MIGHT still be ok, more than that and you are courting disaster..

keep topping the tank up to dilute the petrol percentage and try not to get on it too hard for a while...

Thanks guys I filled up another R300 diesel today It seems to be going fine :coolShake:
