Lotus Fuel Drain


Filling Diesel in a Petrol Lotus is a regularly occurring error. And its solution depends upon several things. If perhaps you want to find out what it is advisable to do about it then read on.
Listed here the most important factors to be aware of whenever deciding on whether to have your car drained:

  1. What level of Diesel have you put into the Lotus, considering that the fuel tank capacity of your Lotus Exige is in most cases roughly 40 litres?
    1. A modest amount of Diesel, less than 2 litres of Diesel in a Petrol Exige will generally not necessarily be a major problem. Experience has demonstrated to us that an amount less than 2 litres (which is roughly 5% of the overall fuel tank) is very often able to be adequately diluted through completely topping the rest of the tank with Petrol.
      It's quite rare to encounter an automobile going through problems with below 5% incorrect fuel contamination. Be aware that it's rare - definitely not impossible to encounter. There are actually a few vehicles that will not endure any quantity of fuel contamination in the slightest.
    2. Between 2 and 4 litres of Diesel in the Lotus (from 5 to 10%) is a 50/50 situation. Our working experience has confirmed that as many motorists get away with this as those people who don't. Whenever you are deciding upon whether or not to chance it and just fill it up bear in mind that it is just like gambling it all on black - you've got a 50/50 chance of it working.
    3. Anything more than 4 litres of Diesel in your Petrol Exige must straight away be drained out as your probability of succeeding with this amount of contamination is certainly less than one in 50 - genuinely huge odds.
  2. Put some Diesel in a Petrol Lotus and drove it: Have you noticed any performance problems ever since putting the incorrect fuel in your Exige? In that case, get it removed irrespective of the volume of Diesel or the contamination ratio. Still running a car that is currently starting to suffer the effects of fuel contamination will probably just end up in even more harm affecting your fuel system parts.
  3. Are you looking for security?
    Then get it emptied. Whatever the contamination percentage, there is inevitably some degree of threat associated with operating a Petrol engine on Petrol contaminated with Diesel. Likely outcomes of driving on the incorrect fuel include things like the engine refusing to start, running unevenly, losing power, degradation of the high-pressure pump, damaged or bunged injectors, etc. These are a few of the most frequently seen Diesel in Petrol signs or symptoms, and should you detect 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.
