3 common misconceptions in truck maintenance, have you fallen into them?

Excessive oil filling

Drivers know the importance of oil, if there is not enough oil will cause damage to engine parts, but too much oil can also cause damage to the vehicle, did you know that?

If there is too much oil in the engine, the crankshaft and connecting rod bearings will experience severe agitation, resulting in a loss of engine power. More seriously, if a large amount of oil splashes onto the cylinder wall, it can cause oil burning. Therefore, more oil is not necessarily better, and it is best to keep the oil level between the upper and lower marks on the dipstick.

The bolts are screwed too tightly

There are many screws on every truck, and many people believe that tightening them as tightly as possible is safer. However, this is not true. Over-tightening only increases the safety risk because it can cause the screws to deform, thereby increasing the risk of thread slippage and compromising safety.

Excessive air pressure in the tyres

It is well known that low tire pressure can cause significant damage to the tires. Therefore, some people believe that higher tire pressure is better, and often tell service personnel to "inflate the tires more" during maintenance.

However, if the tire pressure is too high, it can reduce the tire's grip coefficient, decrease braking performance, increase lateral slip, and pose a significant safety hazard while driving. Moreover, high tire pressure can reduce the tire's contact area with the ground, increase wear and tear, and increase the risk of a tire blowout (imagine the consequences of a tire blowout at high speed!).

The correct approach is to inflate the tires to the standard pressure indicated on the tire, and not to be overly smart about it!
