You might not think it but the likelihood of a diesel owner putting petrol in their car is high! One reason for that is because the filling station nozzle for petrol is narrower than a diesel one.

That means it’s easy to insert a petrol nozzle into a diesel filler neck, but not vice-versa. Still, that’s little comfort to you if you’ve gone and filled up with petrol in your diesel vehicle!

By now, you are perhaps wondering what you should do next. You might be thinking that you’ll have to spend four-figure sums to get your car repaired. You might even be panicking that you need to buy a new engine for your pride and joy!

The first thing to do is not panic about the situation. Yes, putting petrol in a diesel car is bad. Your engine will still run but the petrol acts as a solvent and will damage your fuel pump and injectors.

How bad the situation is will depend on what you’ve done. Read on to find out more:

You’ve added around five litres of petrol

In the grand scheme of things, five litres of unleaded fuel will not kill your diesel engine. It also won’t do any irreversible damage to your fuel system components either.

The best thing to do in that scenario is to fill up your tank with diesel. Yes, the fuel will be a little diluted. But, it isn’t bad enough to make you get your credit card out for a massive repair bill!

You’ve added more than five litres of petrol

Have you only noticed your mistake after you’ve filled your tank up with petrol? If you haven’t started your car’s engine, the news still isn’t bad enough to make you cry!

What you can do is call a mobile fuel drain service to visit you at the filling station. As their service suggests, they will pump out and drain all fuel from your tank. You can then add some fresh diesel and drive away with a sigh of relief.

You’ve started your engine and have more than five litres of petrol

The worst case scenario is that you’ve started driving your diesel car with a full tank of petrol. Your engine won’t explode with a spectacular display, but it won’t be happy either.

You might not believe it, but your diesel engine won’t blow up or have a catastrophic meltdown! Here is what you need to do:

  1. Stop driving;
  2. Get your tank drained and the fuel system flushed;
  3. Replace the fuel filter with a brand new one; and
  4. Fill up with diesel.

The above scenario is perhaps the most expensive one of all. But, it’s still cheaper than getting a new engine or even a new car. We all make mistakes; we are human after all.

If you’ve put petrol in your diesel car by accident, the good news is that the problem is fixable. And you don’t have to spend a fortune resolving the problem either. Good luck!
