Not sure about the oil thing mate, just keep topping it up with diesel it won't do any harm.

Petrol and Diesel are injected at different times during the strokes. Swapping the fuels will cause premature ignition

Diesel is introduced during compression where as petrol is introduced before (on the down stroke).

Diesel is worse in a petrol engine as the spark alone isn't enough to completely burn the fuel so you get nasty smoking from the back. Can also damage the cat which is never good eh?

Petrol in a diesel engine isn't the worse thing in the world as it will still ignite under the high pressure but in large dosage/percentage causes the engine to run rough as the engine isn't designed to handle such a 'wollop'

as Dabsy said, will probably give the old oil-squirting injectors a good clean :D

Hope this helps

Wont do any harm at all!

+1 I second that. Realistically, you will be fine. When you break it down to raw engineering, Fuel is Fuel. Just like how Oil is Oil. At the end of the day, you can run your Diesel lump on used chippy oil lol

      X3 2.0 automatic

      hi , I had very similar problem a while back, and after a lot of testing with vista, it turned out to be a front R/H wheel , speed/wheel sensor. when it all was happing lots of codes were coming up gearbox, diff front and back, transever box,plus many more, didn't look good, but there was one code that repeatedly came up at the top of the list, at this point it was becoming undriveable ,it just didn't seem that a wheel sensor could cause all these codes. So I went got two wheel speed sensor, replaced driver side front, the problem never came back, the sensor controls so many systems ,cleared all codes, happy days, I could have pulled the car apart for nothing, and got nowhere, except an empty wallet. hope this helps you or someone.

      105C thermostat replacement

      As I understand the wiring diagrams and operation Item 9 on the thermostat housing is the sensor which sends its signal to the ECU for interpretation with information from the map sensor. Information from item 12 (1st drawing ) is also used to provide average temp across the cooling system. As far as I am aware the Thermostst is independent of the sensors and operated by expanding wax material internally

      BMW 318i boot locked can’t get into

      Errr not clear here Donald Plastic "L's" with short rubber hoses ??? Distilled water/Ionised water should only be used in an old style lead acid battery. The Rad and engine coolining system should be filled with the correct coolant mix to prevent cavitation and the danger of freezing in low temps. Coolant should be part of the cars regular maintenance and changed every 3 years or so. At that time all hoses and connectors should be inspected and changed where necessary to keep everything in tip top condition. Changing parts can cause as many problems as you may think your solving
