Volvo Fuel Drain


Putting Diesel in a Petrol Volvo is a very common error. And what you need to do about it varies according to a variety of things. If perhaps you want to know what you need to do about it then stay with me.
Listed here are the most important variables to keep in mind whenever making a decision whether or not to have a fuel drain:

  1. How much Diesel did you put in to the Volvo, bearing in mind that the fuel capacity of the Volvo C70 is probably roughly 62 litres?
    1. A modest amount of Diesel, less than 3.1 litres of Diesel in a Petrol C70 will typically not necessarily be a significant problem. Experience has demonstrated to us that quantities less than 3.1 litres (close to 5% of the whole fuel tank) is sometimes able to be completely diluted by means of wholly filling up the rest of the tank with the appropriate fuel.
      It is rather unusual to encounter a car going through problems due to under 5% incorrect fuel contamination. Remember that it is rare - certainly not impossible to encounter. There are a number of vehicles that will not endure any degree of contamination in the slightest.
    2. Anywhere between 3.1 and 6.2 litres of Diesel in the Volvo (5 to 10%) is really a 50/50 situation. Our working experience has proven that as many motorists get away with this as those who break down. Whenever deciding upon whether or not to chance it and just fill it up remember that it is just like betting everything on black - you've got a 50/50 chance of it working out.
    3. Anything over 6.2 litres of Diesel in your Petrol C70 ought to as soon as possible be drained out seeing as your likelihood of succeeding with this amount of contamination is in all likelihood less than one in fifty - extremely huge odds.
  2. Put some Diesel in a Petrol Volvo and drove it: Have you spotted any performance difficulties as a result of putting the incorrect fuel in your C70? In that case, have it emptied irrespective of the quantity of Diesel or even the contamination percentage. Proceeding to drive driving a car that is currently beginning to suffer from the consequences of fuel contamination will likely be responsible for progressively more damage being done to the fuel system parts.
  3. Are you interested in reassurance?
    Then get it emptied. Regardless of the contamination ratio, there is invariably some extent of risk connected to driving a Petrol engine on fuel contaminated with the wrong fuel. Likely results of driving a vehicle on the wrong fuel normally include the engine not starting, running lumpy, loss in power, degradation of the high-pressure pump, worn out or clogged injectors, etc. These are some of the most typical Diesel in Petrol warning signs, and in the event that you notice any of them stop driving and have it drained asap.

Diesel in Petrol Questions

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.
