Lube to avoid these three problems
AT the Bauma Construction Expo held in Gauteng last week, German lubricator Liqui Moly demonstrated how to simplify vehicle and machine maintenance and extend maintenance intervals by simply using the right lube.
“Less downtime means more productivity and fewer costs,” explained Roland Schmidt, who is in charge of the Construction and Industry division at Liqui Moly Germany.
He listed five problems that also affects cars and demonstrated how preventive maintenance quickly saves operators and drivers money.
Dust in the motor oil
There’s no way to keep dust from getting into the motor oil when running engines in a dusty environment.
This significantly increases wear in the engine. The more dust accumulates in the motor oil over time, the worse the wear becomes.
Add a cleaning additive to the engine before an oil change so that the active ingredients can float the dust particles in the oil, allowing it to be drained off before fresh oil is added.
High sulfur diesel fuel
This creates sulfuric acid during the combustion process in the engine.
That’s why engine oils include additives which neutralise sulfuric acid products, so that they cannot do any harm. But the neutralising capability is limited. Once the additives are depleted, engine corrosion will occur.
Those who want to be on the safe side change the oil at shorter intervals — or use dedicated motor oils that offer a higher acid protection and can significantly extend oil change intervals.
Minute particles get stuck in the injectors’ nozzles over time.
These prevent the injectors from atomising the diesel fuel into a fine spray. An irregular spraying pattern has an immediate effect on the engine performance.
Power and torque are reduced and fuel consumption increases. Poor diesel fuel quality makes all of this even worse.
Several concentrated additives are sold that can be added to the vehicle fuel tank to remove harmful deposits, protect the fuel system from corrosion and increase the life cycle of the injectors.
As Wheels has warned, not all work equally well, but Liqui Moly backs its additives with more than 50 years’ experience and sales in 110 countries.
