The engine heater is located underneath the bonnet and is used to warm up the engine. There are many benefits to an engine heater:
It is not only the weight of the caravan that increases the fuel consumption. The additional air resistance also plays a part.
Keeping the engine heater on for too long is unnecessary and bad (as it uses up electricity without any benefit).
Walking around in a storm with a large open parasol in front of you is hard. The same is true for the car. The fewer wind-catching areas there are, the less fuel is needed to propel the car. Things to consider when it comes to air resistance:
A steel marble will roll better than a deflated football. The same is true when it comes to the tyres of the car. Tyres with high air pressure will roll more easily than tyres with less air in them. The more easily the car rolls, the less fuel it takes to propel it. It also reduces the wear on the tyres.
10–15% over the tyre pressure indicated in the manual is usually best. Read more about tyre pressure in the section on tyres.
These days, toxic HA oils are prohibited within the EU. But there are other aspects that make your tyres more or less environmentally friendly. Tyres with low rolling resistance and recycled rubber are good for the environment. If you want to be even more green, you can buy ecolabelled tyres.
The air conditioning (AC) uses a lot of energy. If you turn off the AC, you can save 5–10% in fuel consumption.
You should wash your car in a location intended for that purpose, such as a petrol station. These places have special floor drains that collect any harmful residues from the wash.
Waxing your car not only makes it look good – the wax also forms a protective film which means that less dirt sticks to the car. This in turn means fewer washes are necessary, which is good for the environment.
