Toyota Fuel Drain


Filling Petrol in a Diesel Toyota is a well-known mistake to make. And its remedy depends on an assortment of factors. In case you want to find out what you must do about this then continue reading.
Listed below are the most crucial factors to think about whenever deciding whether to get it drained:

  1. What level of Petrol did you put into the Toyota, bearing in mind that the fuel capacity of your Toyota iQ D-4D is normally roughly 32 litres?
    1. A tiny quantity of Petrol, less than 1.6 litres of Petrol in a Diesel iQ D-4D will in most cases not really be a significant problem. Experience has shown us that anything less than 1.6 litres (approximately 5% of the overall fuel tank) is quite often capable of being completely diluted simply by entirely topping the remainder of the tank with the right fuel.
      It is very unusual to encounter a motor vehicle having issues because of lower than 5% incorrect fuel contamination. Remember that it is very uncommon - definitely not impossible to encounter. There are a few automobiles that don't endure any quantity of fuel contamination whatsoever.
    2. Anywhere between 1.6 and 3.2 litres of Petrol in the Toyota (5 to 10%) is really a 50/50 scenario. Our working experience has proven that as many motorists get away with it as those who break down. Any time you're trying to decide whether to risk it and just simply top it up bear in mind that it is very much like betting everything on black - you have got a 50/50 possibility of it working.
    3. Anything more than 3.2 litres of Petrol in your Diesel iQ D-4D ought to promptly be drained out seeing that your probability of driving with that level of contamination is probably less than one in 50 - genuinely huge odds.
  2. Put Petrol in a Diesel Toyota and drove it: Have you spotted any performance troubles ever since putting the wrong fuel in the iQ D-4D? In that case, have it drained regardless of the amount of Petrol or the contamination percentage. Continually driving a car that is currently beginning to suffer the effect of fuel contamination will just cause progressively more damage affecting your fuel system parts.
  3. Are you looking for security?
    You should get it drained. Regardless of contamination percentage, there is inevitably some degree of risk affiliated with running a Diesel engine on Diesel contaminated with the wrong fuel. Likely final outcomes of driving a car on the incorrect fuel include the motor refusing to start, running unevenly, loss in power, degradation of the high-pressure pump, worn or bunged injectors, and the like. These are some of the most typical Petrol in Diesel signs or symptoms, and should you detect any of them stop and get it drained as soon as possible.

Petrol in Diesel Questions

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

I put Petrol in a Diesel 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 Diesel car on Petrol 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 Petrol can I get away with in a Diesel 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 Diesel 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.
