(Not) replace the filter – the engine “condemned”?

Expand resource…

Theoretically, any combustion engine can run without filters, but not for long.

The air always contains dust, engine oil is contaminated every second by mechanical wear products from rubbing parts, and together with gasoline, dust, rust, water and other uninvited guests enter the engine cylinders. That’s why every internal combustion engine has oil, air and fuel filters.

There are more and more counterfeits on the auto parts market, and one of the most common are filters.

On older cars, the fuel filter was located outside the tank, so replacement is not difficult. It is enough to disconnect two quick-release tips.

…or ruin the engine?

The principle of operation of all filters is simple – in fact, these are “sieves” that trap foreign particles.

But the initial requirements are contradictory: it is impossible to capture all the dirt at once without resisting the useful flow of air, oil or fuel.

Only a blank partition can ideally retain dirt, and only the absence of a filter per se can reduce the resistance to zero.

For this reason, any filter is a compromise and far from eternal: from time to time it must be replaced with a new one. In addition, not all companies can produce high-quality filters. It’s hard to believe, but in many cases, behind the familiar and reliable appearance is a worthless filling.

At the same time, a high-resistance air filter will initially choke the engine, and its oil counterpart with an unusable bypass valve will drive untreated oil into the line.

What to choose?

It seems that it is not difficult to choose a worthy filter – just stop at a well-known brand.

But a problem arose: the sanctions regime led to some high-profile suppliers leaving the Russian market, and their place being taken by manufacturers of “left-wing” goods with stolen names and unpredictable characteristics.

It is rather difficult to spot a fake immediately: from the outside it may look quite decent, but only the engine itself will quickly feel the flaws in its internal contents.

Therefore, it makes sense to look at domestic filter manufacturers. Their products are practically not adulterated (at least for now), and the technical characteristics are not inferior to eminent “foreigners”.

Those who still doubt the suitability of such a replacement can be recommended to replace filters more often. So to speak, for your own peace of mind.
