Common questions

40% of LPG comes from the refining of crude oil and 60% straight from field production. At atmospheric pressure it is a vapour, under modest pressure it becomes liquid.

This is not uncommon, so make the switch when your vehicles come up for replacement. Let us carry out a cost saving analysis now so you can see the benefits of changing your fleet to run on Calor Autogas.

Currently there are more than 1,400 LPG refuelling stations in the UK, and this number is constantly increasing - however depot based fleets can take advantage of LPG immediately by installing their own tank on-site.

Autogas retails at around half the price per litre of unleaded petrol and diesel. In practice this means that an Autogas vehicle is about 40% cheaper to run than a conventional fuelled equivalent, so depending on your mileage, the payback period of the Autogas conversion (currently around £1600) could be less than 2 years.

All LPG tanks are rigorously tested and all are considerably stronger than conventional fuel tanks. The UK has stringent safety standards for Autogas vehicles and by selecting a reputable equipment manufacturer and/or converter approved by the LPGA you are assured peace of mind.

Carbon dioxide is widely regarded as a main contributor to the greenhouse effect, which is making our planet warmer. Autogas reduces CO2 emissions from vehicles previously powered by petrol by 15%. Autogas also emits 97% less Benzene than unleaded petrol.

The black smoke that we see coming from diesel vehicles cause over 20,000 premature deaths a year. By replacing a diesel engine with an Autogas equivalent, over 90% less of this particulate matter would be emitted.

Yes, and with bi-fuel you'll almost double your range. The petrol tank still remains in the car and the driver can switch from gas to petrol, or vice-versa.

No. In fact, LPG is a cleaner burning fuel engine, so life is extended and less maintenance is required.

There is very little difference in performance - however, with a liquid injection system, performance can be increased by 5%. Some drivers find increased drivability and for anyone used to driving on diesel, there's obviously a significant reduction in noise.

All OEM bi-fuel vehicles carry full manufacturer's warranty. Most retrofit conversion specialists will cover the LPG systems; however this needs to be checked.

For a range of about 300 miles most tanks take up less space than a spare wheel.
