Black Panther 1,675 Posted February 17, 2018 Share Posted February 17, 2018 So in a moment of inattention I put petrol into a Jerry jug normally reserved for diesel. There was probably less than a thimble full of diesel in there. Can I put that petrol in my car? If I do that and let it dry out can I then continue to use it for diesel?

Island Time 1,278 Posted February 17, 2018 Share Posted February 17, 2018 Yep, it'll be fine, as long as it's only a thimble full.. Quote Link to post Share on other sites

Black Panther 1,675 Posted February 18, 2018 Author Share Posted February 18, 2018 Ok. The car was half full so that would further dilute it. Quote Link to post Share on other sites

wheels 543 Posted February 18, 2018 Share Posted February 18, 2018 If you did happen to have too much Diesel in the Petrol BP, then you might notice a little blue smoke in the exhaust from the Car.You can also get away with a little Petrol int he Diesel also, with no adverse affects on the Diesel Engine. In the really cold climates, they add 10% of Petrol to Diesel to allow easier starting. I don't recommend that for here though. If there is too much petrol, it will cause Pingking or more accurately, Detonation. A sound like someone inside the engine with a hammer smacking the metal. If the engine does that, then it is not good to run the engine for too long as damage can be done. If it does it during acceleration only, then just put the throttle down a little more slowly and get more diesel into the tank as soon as you can. You don't need to drain the tank unless you have filled a 1/3rd to 1/2 empty (or should that be 1/2 full) all the way up with Petrol. Quote Link to post Share on other sites
erice 732 Posted February 21, 2018 Share Posted February 21, 2018 after switching from many years with diesel vans to a petrol car once made the error of putting $10-5 ltr of diesel into the near empty 60 ltr tank of the car the attendant suggested waiting 2 hours and paying $120? to a guy who would pump it out but decided that a petrol/diesel mix of 90/10 was unlikely to cause any problems so filled the car with petrol drove off without any noticeable difference petrol / diesel at 50 / 50 however starts to give horrible running and lots of white smoke, but still provides low power (as found out when almost running out of fuel taking a small tanked ducati deep into remote mountains) the bigger danger is the other way round when anything above a 50 / 50 mix in a DIESEL engine is almost certainly going to blow out the head gasket when high octane petrol starts getting hammered by the 20:1 compression of diesel engine.......... but again if you don't rev the hell out of it you may just get away with it Quote Link to post Share on other sites
ScottiE 174 Posted February 21, 2018 Share Posted February 21, 2018 My mechanic neighbour reckons I should chuck a litre of petrol into my diesel wagon once every 6 months to clear out the injectors on the CR. Haven't had the balls to yet so maybe I should! Quote Link to post Share on other sites
wheels 543 Posted February 21, 2018 Share Posted February 21, 2018 Scottie, Kerosene is the better product for injector cleaning. However, NZ Diesel is very high quality and also has a cleaner of sorts in it. You would not notice any improvement. Same with any of the injector cleaners you can buy. None of them make any improvement that would make the cost if using them worth while. These cleaners worked well oversea's in countries where cheap fuels and high levels of sulphur are present.The bigger danger of a high mix of Petrol in Diesel is lack of lubrication. Diesel is in fact an oil and it has great lubrication properties. For the injector pump, this lubrication is essential.A mate of mine accidentally put Petrol into his Diesel Toyota Hiace Van. A Lot of it!! Twice!! He had to have a new Injector pump and injectors. Luckily he had idiot insurance and that covered the fix. But it cost thousands. What they didn't test for at the tome was compression. After it was all fixed, he found the Vehicle started using huge amounts of Oil. Now the bottome end needs rebuilding and that is going to cost $5K and insurance isn't paying for that part. Quote Link to post Share on other sites
ScottiE 174 Posted February 21, 2018 Share Posted February 21, 2018 Cheers Wheels - had heard something similar"from the other side of the fence". The "go for longer drives in the country" advice was far more appealing anyway! Quote Link to post Share on other sites
