Frequently Asked Questions

BioFuel is much cleaner than normal mineral diesel but there is so much more to it than just the environmental impact.

What modifications are required?

None. BioDiesel can be used with no modifications required. Simply fill and go.


Why should I use BioDiesel in my vehicle?

You can save £1000’s a year by switching to BioDiesel. BioDiesel is 100% legal to use in your car, van taxi or truck.

What is BioDiesel?

BioDiesel is an alternative diesel fuel made from new Rapeseed oil. It can be used just like normal diesel in any car without any conversion costs and is almost odourless.

Will it be OK in my vehicle?

Yes, please note though that older vehicles (pre 1990) have rubber pipes within the engine which could deteriorate over time (years). However they can be inexpensively replaced (£15) enabling the vehicle to run on BioDiesel. BioDiesel is safe to use in all conventional diesel engines, as you may not know you are already using BioDiesel in your vehicle as every litre of fuel you buy from a forecourt must contain a minimum of 5% BioDiesel by law, Morrisons contains 7%.


What's this I've heard about having to change my fuel filter?

Normal diesel forms sediments that stick to and accumulate in your fuel tank this is why there is a fuel filter in every vehicle, over time this accumulation forms layers of sludge. BioDiesel will dissolve and clean these deposits from your fuel tank, fuel line and engine. Although it is unlikely, material flushed through your fuel system may clog your fuel filter which you may then need to change.


Is BioDiesel the same as “reddiesel” or “gas oil”?

No. Red diesel and gas oil are rebated fuels and are illegal to use in your car. BioDiesel however has been made especially for road use. Its fuel duty and tax have been paid on it making it 100% legal for all road use, for cars, vans, taxi’s, HGVs etc.

Will BioDiesel affect my engine?

BioDiesel has been used in cars, vans, taxi’s and HGVs all over Europe for over 12 years. Even the UK taxing laws have changed to give BioDiesel a cheaper rate of tax to encourage more use of BioDiesel in this country. Many BioDiesel consumers have noticed better m.p.g., quieter smoother engines, longer engine life and a major reduction in carbon dioxide.

Will using BioDiesel affect my car's performance?

BioDiesel is a natural cleaning agent, which means it will very quickly clean out your engine and improve performance and fuel economy. It will reduce particulate emissions (which is that cloud of black smoke you can see from a diesel car that pulls away in front of you) by up to 60%.

Can I mix traditional petroleum based diesel and BioDiesel?

Yes you can, you can blend both fuels and it won’t affect your vehicles performance.

Why should I buy BioDiesel from Fuller-Fuel?

BioDiesel reduces this by approximately 50%
