FAQ for wrong fuel in car?

Whatever you do, do not turn on the ignition or start the car. It is much less common to put diesel in to a petrol car than to put petrol in to a diesel car, because the standard diesel nozzle at fuel stations is larger than the fuel filler neck on modern petrol cars – the simple fact that the filler neck won’t accommodate the diesel nozzle means you have to be pretty determined to mis-fuel your petrol car with diesel. If this should happen, call Highland Fuel Drain straight away and we will be there to assist you, normally within 1 hour.

Generally, a small amount of diesel in your car should not damage the engine, as long as you have not turned on the ignition or started it and you then make sure you top up fully with petrol.

If you’ve added more than 5% (2.5 litres in a 50 litre tank) diesel – we will need to fully drain the tank and refill the car with petrol. If you’ve added less than 5% diesel – You may not need to drain or flush the diesel fuel from the car and may be able to fill the fuel tank with petrol unless your manufacturer’s warranty (should you have one) says otherwise.

Diesel engines have fuel pumps that work on very fine tolerances and are lubricated by the actual diesel fuel itself. Petrol in diesel fuel acts as a solvent – it dissolves the active lubrication in diesel which may cause damage to many internal components including the high pressure fuel pump through the sheer metal to metal contact.

Some advanced fuel system seals can be affected by the compounds in petrol too. As a rule of thumb the further the contaminated petrol goes in the diesel fuel system the more expensive the repair costs will be. Some manufacturers advise that seals and filters should be renewed even if the engine has not been run. This particular remedial action will not be nearly as expensive as having to replace the entire engine.

The HDi diesel engines, or common rail diesel systems, are particularly vulnerable – if petrol fuel works it way in to the high pressure fuel pump, the metal to metal wear creates debris, if this gets further in to system you may also have to replace the low and high-pressure fuel pumps, injectors, fuel rail, line filters and the fuel tank too. This shows what a nightmare can be created by the simple act of putting the wrong fuel in your car.

Many diesel engines use a low-pressure electric pump in the tank or sender unit and this begins to work as soon as the ignition is switched on, circulating the contaminated fuel through the pump and rail – so if you’ve put the wrong fuel in your car it’s important not even to turn the ignition on and the engine must certainly not be started.

INCORRECTLY FUELED VEHICLE DISCLAIMER.

DUE TO THE NATURE OF INCORRECTLY FUELING A VEHICLE, HIGHLAND FUEL DRAIN, REFUSE TO GIVE ANY GUARANTEE OR UPHOLD ANY LIABILITY CLAIM MADE WITH RESPECT TO ANY FUEL DRAIN UNDERTAKEN.

THE OWNER / DRIVER OR PERSON RESPONSIBLE FOR THE INCORRECTLY FUELED VEHICLE, MUST ACCEPT FULL LIABILITY FOR ANY DAMAGE CAUSED OR FOR FURTHER COSTS INCURRED DUE TO RE-FUELING WITH THE WRONG FUEL, REGARDLESS OF IF THE ENGINE HAS OR HAS NOT BEEN STARTED.

Once fuel draining is complete and all contaminated fuels have been removed, fresh fuel must be added to the tank. We will do our very best to get the vehicle re-started.

In the event engine damage HAS occurred and the engine will not start or it starts with obvious running issues.. Highland Fuel Drain will be unable to offer any further assistance! The vehicle will need to go into a garage to diagnose in-depth the damage that wrong fueling has caused.

It’s the responsibility of the Owner / Driver / Person in charge of the vehicle to pay our bill in full and arrange to have the vehicle removed.

If in the very unlikely event we are unable to drain / remove the contaminated fuel from your vehicle, We will NOT require any form of payment, as we have been unable to undertaken the task asked of us.

Putting the wrong fuel in your car is not usually offered as part of a breakdown membership and is a separate service. The breakdown company is likely to charge you around double, if not more than what we charge to do the same job – regardless of you being a member. We are always the cheaper option.

If you have started a car with the wrong fuel and it has turned itself off due to mis-fuelling, we can still help. Turn the car off immediately and refrain from putting the key in the ignition. Call us as soon as and our engineers will drain, flush and re-fill your car with the correct fuel to get you started again.

This all depends on the size of your tank and the vehicle that’s been mis-fuelled, we recommend anything over 5% of the car’s full tank capacity will need to be drained to prevent damage. Newer model cars are less tolerable to the wrong fuel being placed inside.
 

Firstly it is important to remain calm in these situations, damage to the car can amount to a lot of money if the car is driven on the wrong fuel. Our engineers are recorded to arrive on site with the customer within 30 mins and our fuel drains take on average 20 mins to complete. This means that after you have called us, we can have your car up and running, helping you to be on your way in under 1 hour.

Here at Econofix we offer a 24hr, 7 days a week service. So no matter where or when you mis-fuel, we will always be able to help.

FAQ FOR TYRES

Correct tyre pressure is important not only for safety, but also for fuel efficiency. It is measured in Bar, as well as pounds square inch (PSI), and you can find the correct information for your vehicle in the manufacturer’s handbook. In many cars, these details are also inside the rim of the driver’s door (and sometimes on the petrol cap).

This information is important when booking a tyre change, and can be found in either the vehicle manufacturer’s handbook or on the sidewall of your existing tyres.

 

By law, car tyres must have a minimum tread depth of 1.6mm throughout the central 75% of the tyre (the tread pattern must be visible in the remaining 25%). For motorcycles, the minimum is 1.0mm throughout the central 75%.

If your vehicle’s tyres are deemed unroadworthy – whether through insufficient tread depth, visible damage or incompatibility with the vehicle – you could be in line for a fine of up to £2,500 and 3 penalty points on your licence. This is applied per tyre, not per vehicle.

If your car’s tyres are unsuitable, it will not pass its MOT.

There are a lot of factors in determining how often car, van or motorcycle tyres need changing, based on regularity of use, driving conditions and more. The safest approach is to inspect your tyres every month for signs of wear and tear, and replace them before they become unsafe.

Seasonal conditions are also a consideration that must be made when it comes to tyre changes. Universal Tyres stock a large selection of winter tyres, and are on hand to provide advice as to the best time to switch.

It’s not just the legal issues (mentioned above) that can be a problem when driving on worn out tyres. Insufficient tread depth also affects braking distance – a particular danger on icier roads – while a tyre not inflated to the correct pressure can impact on fuel efficiency and handling ability.

 

Wheel alignment ensures that a vehicle’s wheels are set to the angle of the manufacturer’s specification at all times. Incorrect wheel alignment can increase tyre wear, as well as causing the vehicle to “pull” to one side while driving.

Universal Tyres use some of the latest wheel alignment technologies and fully trained technicians to ensure that your vehicle runs true and is safely set up to get the best ride quality and tyre wear longevity possible.
