Chevrolet Fuel Drain


Filling Diesel in a Petrol Chevrolet is a common error. And what you have to do about it varies according to a number of things. If perhaps you want to know what it is best to do about this then read on.
Let us discuss the most crucial variables to keep in mind whenever making a decision whether to have it drained:

  1. How much Diesel have you put in to the Chevrolet, taking into consideration that the fuel tank capacity of the Chevrolet Trail Blazer is usually about 71 litres?
    1. A modest amount of Diesel, as little as 3.55 litres of Diesel in a Petrol Trail Blazer will typically not be a significant problem. Experience has taught us that an amount under 3.55 litres (which is almost 5% of the entire fuel tank) is sometimes capable of being adequately diluted through wholly topping up the remainder of the tank with the appropriate fuel.
      It's highly rare to come across a car suffering from issues because of below 5% wrong fuel contamination. Keep in mind that it is unusual - certainly not impossible to find. You will discover a few motor vehicles that won't stand any amount of contamination in the slightest.
    2. Between 3.55 and 7.1 litres of Diesel in the Chevrolet (from 5 to 10%) is really a 50/50 scenario. Our experience has shown us that as many drivers get away with it as those who break down. Whenever trying to decide whether or not to risk it and basically top it up bear in mind that it is the same as gambling all of it on black - you will have a 50/50 chance of it being ok.
    3. Anything over 7.1 litres of Diesel in your Petrol Trail Blazer should straightaway be drained out seeing as your probability of succeeding with that amount of contamination is almost certainly lower than one in 50 - definitely big odds.
  2. Put Diesel in a Petrol Chevrolet and drove it: Have you noted any performance concerns ever since putting the wrong fuel in the Trail Blazer? If you have, have it emptied irrespective of the volume of Diesel or even the contamination ratio. Proceeding to run driving a motor vehicle that is now starting to suffer from the effect of wrong fuel contamination can typically be responsible for even more damage being caused to the fuel system parts.
  3. Would you like reassurance?
    Then simply just get it drained. Regardless of contamination percentage, there is always some amount of threat affiliated with driving a Petrol engine on Petrol contaminated with the wrong fuel. Likely consequences of driving on the incorrect fuel can include the engine not starting, running unevenly, loss of power, wearing of the high-pressure pump, worn or blocked injectors, and so forth. These are several of the most frequently seen Diesel in Petrol warning signs, and if you recognise any of them cease driving and get it removed right now.

Diesel in Petrol FAQs

When someone has put Diesel in a Petrol car they have a few very common questions. So we have compiled a list of the most Frequently Asked Questions for you

I put Diesel in a Petrol car and drove it. What do I do?


Turn off the car as soon as possible and call us. Continuing to run a vehicle on the wrong fuel can potentially damage it. We will be able to give you advice and assistance based on your circumstances

Will driving a Petrol car on Diesel cause damage to it?


It can. However, if the problem is caught and remedied quickly the risks will be minimal. Of the 1,500 vehicles we attend every month, less than 0.5% have suffered and substantial damage requiring parts replacement.

How much Diesel can I get away with in a Petrol car?


The safe answer is none. However you might be able to get away with a very low contamination ratio. That being said, we always highly recommend draining anything over a 5% contamination ratio asap.

I know about petrol in diesel, but what about Super Unleaded?


Putting Super Unleaded, or Shell V-Power, BP Ultimate Unleaded, etc, will have the exact same effect as putting regular unleaded petrol in your diesel car and will need to be drained out and flushed.

Will getting you to do a fuel drain void my warranty?


No! The EU Block Exemption Regulations clearly state that "the work can be carried out by as long as that garage uses manufacturer approved parts and correctly follows the manufacturer's service schedule."

Can I top it up with Petrol and add some 2-stroke oil?


This might work on some vehicles in some cases, but in the majority on instances it won't and you risk damaging the Lambda sensors as well as fuel pump and injectors, just as a regular misfuel.
