With the ever rising prices of petrol, it’s becoming increasingly essential to look at ways of saving money by means of Eco driving. Simply changing the way you drive can save a significant amount of petrol, adding up to great savings over a relatively short period of time.
Simple changes to your driving techniques allows smart Eco driving to save not only fuel but no loss of time in reaching your destination. This how to save petrol section will provide information for Eco driving; that will not only save you petrol or diesel, but provide a safer driving experience and reduce the amount of CO2 emissions released.
Below are 16 top tips on saving money on petrol or diesel fuel expenses.
- 1. Driving at high speed
Air resistance is a significant factor when driving at speed. The faster you go, the higher the resistance meaning more energy is needed. The energy needed to accelerate your car from 10 mph to 20 mph is minimal as the only energy required is to move the weight of the car with slight air resistance.
Motorway and dual carriageway speeds of 70 mph account for 40% of the cars energy being used due to air resistance. This percentage increases rapidly with even the slightest gain in speed. To give an indication of how air resistance decreases fuel efficiency, driving at 70 mph compared to 60 mph uses 9% more fuel, driving at 70 mph compared to 50 mph uses 15% more fuel. Just an extra 10 mph by driving at 80 mph compared to the legal speed limit of 70 mph can use a staggering 25% more petrol.
Let’s say you have a 60 mile trip to make on a 70 mph dual carriageway or motorway. Traveling at over the speed limit of 80 mph will save you only around 6 minutes compared to driving at 70 mph. Considering you can use 25% more petrol at 80 mph, it really doesn’t seem worth it.
- 2. Reading the Road
Your engine simply pulling the weight of the car in urban cities and towns is now the factor and not so much air resistance. Reading the road ahead effectively can save huge amounts of petrol.
As we all know, there are often queues of traffic at traffic lights, junctions, roundabouts etc. Looking well ahead whilst driving and anticipating a stop is beneficial. Ease off the accelerator well before you reach the traffic queue and apply the brakes gently as you get closer. Driving in such a way, by keeping your foot off the accelerator and using the cars momentum uses no petrol. If you compare this to keeping the accelerator on and braking harshly when you reach the queue, you can easily save over 5% of petrol……..click to continue reading
