Benefits Of Using High Zinc Motor Oils

Even though modern cars don’t need high zinc motor oil to function, there are numerous benefits to using it. Here are the most prominent ones:

1. Works Well In Extreme Conditions

Regular engine oil won’t do a great job when there are frequent changes in the temperature, conditions of the road, and high-speed driving.

But oil with a high amount of zinc additives provides good resistance against heat and oxidation, which results in smooth performance.

2. No Cold Start Failure

Using the wrong engine oil can lead to issues with starting the car in extreme weather conditions, especially when it’s cold.

But high zinc motor oils perform well even in this low-temperature situation. You’re not likely to face any trouble when starting the car with this type of engine oil.

3. Better Protection At High Speeds

When you drive the car at high speeds, the camshaft of the engine rotates and presses its lobe to open the engine valves. Regular motor oil can get squeezed through the lobes due to the pressure build-up.

The lack of oil can lead to parts rubbing on each other and damaging your vehicle. But a high-zinc motor oil has anti-wear properties that’ll keep the engine protected even in this condition.
