How to Ruin the Engine: 6 Surefire Ways

In order to understand how to extend the lifespan of the engine, you need to know why it is aging. The life of the engine is shortened due to accelerated wear of friction pairs - primarily piston rings and bearing liners (of connecting rods and crankshaft).

In turn, this is due to abnormal working conditions of these pairs, like improper lubrication or excessive loads. And that's why it happens.

Inappropriate oil

Still, few car owners know that the oil has to be selected by several indicators, not only by viscosity, for example. That kind of oil recommended to you by a neighbor is not necessarily as good for your Honda as it is for his Dodge. An incorrectly selected oil lubricant can harm the engine on several fronts at once: at high loads due to a thin oil-film wedge and in moderate modes due to corrosion owing to low acid-base stability of certain engine oils.

Failure to change oil

Systematic delays in oil change lead to a deterioration of the lubrication conditions of the friction pairs. The fact is that the expired oil performs its functions only partially, since it is full of additives: increased acidity and reduced cleaning properties. Dispersants also stop preventing the deposition of slags. So, oil components do not perform their anti-wear functions.

Engine overheating

Fortunately, this happens rarely but can lead to dire consequences: missed emergency readings of the thermometer, unwatched coolant level, failed fan sensor, miscalculated load when traveling through mountains, snow or mud. Burnt oil coxes the piston rings so that they stop cleaning off fresh oil. Soot deposits start accumulating and crumbling. They work as an abrasive on the walls of the cylinders… In short, only the replacement of the piston rings will not get off in this situation, although even this procedure is not cheap – at least $200. Not to mention purely consequences of potential accidents: curvature of the cylinder head, burnout of gaskets, displacement of valve seats, cracking of piston partitions. So you need to make a vehicle inspection in time. If the car is not new, do not forget to monitor its driving and gauges.

Doctor's cycle

In this mode, the doctor travels around the city: short trips from patient to patient with downtime at each apartment. Condensate is constantly present in the engine of such a car, what forms acid from the fuel sulfur. It speed ups the process of oil oxidation and causes corrosion.

Frequent idling of the engine at traffic lights exacerbates the negative effect. During the cold weather, electronics enrich the fuel-air mixture, and gasoline washes the oil from the cylinder walls, impairing their lubrication. Our advice: use high-quality oil with high stability indicators and let the engine warm up at least once, so that the moisture evaporates from the crankcase. The hood with additional noise- and thermo-insulation will help the engine keep warm during standstill.

Ragged driving

High loads on the cylinder-piston group at sharp accelerations are supplemented by outputs at extremely high speeds. The piston rings and pistons in the contact zone with them have time to overheat, but the revs dropped at the next intersection do not allow the oil and water pumps to feed the necessary portions of oil and coolant to the heated zones. The rings are coxed; the oil untimely ages and loses its properties. Our advice is to change your driving style or buy a car with a sporty-like engine right away.

Each engine model has its own range of optimal rpm both in terms of dynamics and unit durability. This is usually the 2000-4000 rpm range Each engine model has its own range of optimal rpm both in terms of dynamics and unit durability. This is usually the 2000-4000 rpm range

Driving at low revs

It would seem that driving «like an old man” should not ruin the engine, but no! If you load the engine, shifting gears at low speed beforehand, the engine will be also ruined, since the load on the bearings of the crankshaft and connecting rods in this mode will be high and their lubrication due to low rpm will be insufficient. Detonation, which is partly mitigated by fuel injection, additionally loads the engine parts in this mode. Therefore, keep the speed in the range of 2000-4000 rpm.

Recommendation

The above list does not mean that you need to constantly think about how to extend the lifespan of the engine during driving. Most of these factors can be eliminated as a bad habit, practicing the skill of „correct“ driving until it becomes second nature.
