The high-quality petrol and diesel Rubis sell contains 100% petroleum, which means that when you buy a litre of fuel from a Rubis forecourt – you receive 1000ml of petrol. If you buy a litre of E10 petrol, you will only receive 900ml of petrol, up to 100ml will be a bio content with a lesser calorific value.
This means that the fuel you buy from a Rubis forecourt therefore has a higher calorific value per litre than if you bought a litre of E10 petrol from another forecourt.
The result is you get more miles from your tank if you use Rubis fuel.
