Drain the tank and pray it don't mess up anything. If you run it, it will make the car run really bad and might even cost you an engine replacement.

AnswerThis sounds like a glass half full or half empty type question. Have the fuel tank drained the fuel filter replaced and if you are really in the mood flush the fuel lines. Other than the low or no power / alot of grey smoke / and engine knock this will clear up as the diesel fuel makes it's way back through the injector pump and to the injectors and finally to the engine. This happens more often than you might think with usually no long term effects to the best of my experiences.

Have got petrol in diesel citroen Picasso what do you need to do?

I have a 52 plate Picasso and my slightly dimmer half put 20 pounds of petrol in my diesel car. There was about 5 - 10 pounds of diesel already in the tank. I simply syphoned the tank with a hose and a bucket. doesnt taste nice i know, then filled it with diesel and a fuel treatment and ive had no problems since. this was a year ago now. Its not usually bad this way round as truck drivers put a small amount of petrol in their tanks to stop them freezing in the winter. its when you put diesel in a petrol engine that you've got a problem.

How will diesel effect a petrol engine?

It won't really hurt the engine.... unless you run it long term... Unfortunately you can't burn diesel well in a petrol engine.... It will smoke alot and miss and have weak power... best thing to do if it was accidental is to top it off with petrol... and when it is half tank... top it off again.... then change the fuel filter. Another idea is to add a double dose of octane booster.... it should help with the smoking and missing

How much is a jeep?

Depending on which part of the world you're from and what specific features you're looking for will give you a range of prices. The biggest difference (where I come from) is between diesel and petrol. With petrol our road user charges are part of the price at the pump. While as diesel you pay less at the pump but get taxed per mile half annually. Typically for a late 2000's Jeep Wrangler over here with an average set of features and petrol, you'd be looking at around $20,000-$25,000USD for a decent one. Hope this helps.
