Does Kirkland Motor Oil Have Any Benefits?

Kirkland motor oil has many qualities that benefit your car’s engine, starting with the fact that it prevents LSPI.

LSPI or low-speed pre-ignition can occur in your turbocharged or direct-injected engines and can cause damage.

The fuel and air mixture combusts before it’s supposed to and causes an unwanted build-up of air inside the cylinders.

Kirkland motor oil is also designed to reduce engine friction which can cause a lot of wear and tear.

High-temperature shearing reduces the efficiency of your engine’s motor oil.

Luckily, Kirkland’s motor oil protects against this by extending the life of the oil, so you don’t have to change it as much.

So, If your car requires an oil change soon or even just a top-up, you undoubtedly want to add in some great quality oil. Kirkland has just what you need, made by Waren Distribution, a company that is known as one of the best in the oil industry.
