How to save fuel. Part 1

The cost of any fuel for cars is not decreasing, but on the contrary – increasing. Drivers are trying to find a solution – how to save on fuel. Let’s try to understand and give some practical advice on how to save gasoline or other fuel for your “iron friend”. After all, if you drive every day, the car becomes another. But the maintenance – a real burden. And you can save money on buying a new car by turning in your old car for recycling:

Keep an eye on the technical condition
It is necessary to replace consumables in time. First of all, you should pay attention to the air filter. If it is heavily contaminated, much less air enters the engine than necessary. As a result, fuel consumption increases.

Oil usage also affects fuel consumption. If you use oil that is too viscous, it increases fuel consumption. We used 5W30 and 5W40 for our experience. Using a more viscous oil (5W40) increased fuel consumption by an average of 0.5 liters, which is 5 per cent.

Tire pressure also affects fuel consumption. If you increase the pressure by 0.3 atmospheres, the fuel consumption per 100 kilometers of run decreases by 0.5 liters. Everything is good, but if the exploitation of the car mainly occurs on city roads, in this case, the load on the details of the suspension increases. And it’s not an economy at all, when you will have to change the suspension. So we think that it is better to increase pressure in tires, when driving long distances. Well, and when operating in the city conditions, it is better to keep the pressure normal. If the tires are “underinflated”, the consumption increases.

Watching the way of driving
German experts have proved that the style of driving influences the fuel consumption. Proper driving can save up to 25% of fuel. To check this statement they tried an experiment.

Fuel consumption was zeroed out and the car was filled up. The dashboard was set to show not the average consumption, but the instantaneous one. Due to it, it is possible to see at once, what actions lead to the increase of fuel consumption.

First of all, after the start of driving, we smoothly shifted gears. At the same time, we tried not to let the tachometer show more than 2500 rpm. Then they tried not to let the car stop for a maximum time. In this case, the economy occurred at the expense of unnecessary acceleration. Particular attention was paid to the maximum speed. It wasn’t allowed to exceed 70 kilometers per hour.

For cars with automatic transmission there is one more trick. It is necessary to switch the box to the state N, during the long traffic lights. This reduces the load on the engine.

After switching the dashboard readings from instantaneous consumption to average consumption, we see that average consumption has dropped from 11.2 liters to 10.1 liters. And that’s more than 10 percent! The most interesting thing is that the average speed of driving in the city remained the same.

We can add that drivers with a manual transmission can save even more.
