• 25% too low tyre pressure increases rolling resistance by 10% and fuel consumption by 2%. • Too low tyre pressure also has unfavourable effects on vehicle handling and braking distance. • To ensure correct tyre pressure, you need to check your car's tyres at least once a month. • Tyre pressures must be checked when the tyres are cold, this means that you have driven less than three kilometres, otherwise you have to wait for about 10 minutes to let the tyres cool down.

Tyre Pressures can save Fuel.

PETROL E10 Unleaded or E5 Unleaded Premium

What’s the difference ?

Petrol: The most common fuel used to power cars in the UK, unleaded petrol is mixed with bioethanol to make them more environmentally friendly. Diesel: Although UK demand has dropped due to some high profile scandals and concerns over diesel’s environmental impacts, common diesel types are regular diesel (low sulphur) and premium diesel. LPG: Standing for Liquefied Petroleum Gas, LPG is made of butane and propane. It’s available at most UK fuel stations and is cheaper than petrol and diesel, although cars need to be specially converted to run on the gas. Biofuels: Although not widely commercially available in the UK on their own, biofuels are currently blended with both standard unleaded petrol and standard diesel to make them more environmentally friendly. Electric: Increasingly common in the UK, battery electric vehicles (BEVs) require no fuel whatsoever and are powered by a rechargeable plug-in battery. Hybrid: Powered by two distinct types of energy (either petrol or diesel and electric), there are two types of hybrid car: plug-in hybrid (PHEV) and hybrid.

What types of fuel are there in the UK? There are six common ways to power your car in the UK:
