As a rule, oil loses its properties quickly enough, and no one forbids replacing it more often than prescribed by the instructions, – says the expert “Behind the wheel” Alexey Revin.
When does it become clear that it is time to change the oil?
Sign #1
Hours must be counted. They are displayed on the on-board computer or you need to purchase a special counter. When oil is cheapmineral or hydrocracked base)it is necessary to replace it after 250 hours of operation, if expensive (synthetic) – after 350 hours.
To calculate hours worked, multiply the average vehicle speed by the allowable oil run time. Let’s say 30 km / h, multiply by 250 hours and get 7.5 thousand kilometers – after such a run, cheap mineral oil will have to be replaced. But expensive synthetic oil with such an average speed can last more than 10 thousand kilometers.
Sign #2
It is necessary to understand whether the machine has to work in difficult conditions. These include off-road and rough terrain, traffic jams; weighing treated with a reagent; use of technology like taxi, harsh climate and so on.
If one of these meets your requirements, you should change the oil at least every six months or every 7500 kilometers.
Sign #3
According to Revin, the consumption, color and smell of the oil must be controlled. You can measure the level every 1-1.5 thousand kilometers. If the oil level did not change at first, and then began to drop sharply, it’s time to add new oil.
In some malfunctions, antifreeze or gasoline gets into the oil. In the first case, a light yellow emulsion appears on the probe and neck cap, in the second case, a characteristic odor. Change the oil after correcting the problem.
