Everyone knows all about the mandatory routine change of engine oil. Even “blondes who ride” have a general idea of why and how this procedure is performed. But there’s a subtlety to it that even many advanced drivers aren’t aware of.
What is the routine procedure for changing lubricant from the point of view of most motorists? Nothing tricky: we unscrewed the drain plug from the engine crankcase and poured the “work” into a previously stored container. Then remove the old filter, install a new filter in its place and fill the engine with fresh lubricant. Don’t forget to first put the oil pan screw plug back in the right place.
But it’s not that simple. If you carefully read the invoices for maintenance carried out in the salon of an official dealer, you can discover the following. It turns out that when you change the oil, technicians often also replace your crankcase drain plug! Of course, this “pleasure” is rewarding in several ways. Somewhere “budgetary” – about 1000 rubles. And somewhere, among the premium car brands, this little piece of hardware is appreciated many times more.
When a car owner is faced with maintenance of a car under warranty, it is almost impossible to fight even such an obvious “money scam” on the part of military personnel. Because they can always refer to the labor regulations approved by the car manufacturer. We don’t know anything, that’s how it should be. But if we service a car that is out of warranty, we can calmly combat such nonsense by replacing a stupid plug.
After all, this is not a filter, but in fact a thick steel bolt. What could wear out over the 10,000-15,000 miles between services? That’s not possible, yes. But sometimes you have to change it. The problem turns out to be a sealing ring, which is placed directly on the ill-fated plug before screwing it into the crankcase.
Some car brands even use steel sealing rings as standard. And when tightening the drain plug with the required force, they deform the thread. This can cause the “oil plug” to leak when reused! Therefore, you should throw away the old screw plug and replace it with a new one with intact threads.
Avoiding such waste is simple. It is sufficient, for example, to use a copper one instead of a steel sealing ring. This ductile non-ferrous metal crumples itself, leaving the steel wire unchanged. But copper is more expensive than iron. And to save money, car manufacturers use steel seals. The question of purchasing new sump plugs or switching to copper rings instead of the ‘original’ is left to the discretion of the car owner.
