How Often Should You Change?

Engine oil begins to lose its viscosity and lubricating characteristics after extended use. However, there is one exception to this rule. Those that drive their automobile at various speeds and abuse it, in general, may need to change their engine oil sooner than necessary.

And, of course, for those who keep their cars in good shape and drive them safely, the vehicle service intervals for changing the motor oil are properly spaced.

Viscosity Recommendation

You can’t overlook the relevance of viscosity when purchasing motor oil for your car engine.

For those unfamiliar with the term, viscosity refers to a fluid’s ability to resist flow. The viscosity of an oil is determined by its temperature; when the temperature is high, the oil will be thinner than when the temperature is low.

It influences heat generation in cylinders, gear sets, and bearings, as well as the rate at which oil is consumed. It’s also in charge of the engine’s smooth running in a variety of temperature situations.

Conclusion

To conclude, there is one last suggestion that your engine may get old but you should examine to see if it is acting strangely and has to be repaired. You might be in luck; perhaps everything is in working order and no repairs are required.

In any case, high mileage lubricants are often the best option for cars that are used frequently and for lengthy travels. However, you should only switch to high-mileage lubricants after a thorough examination.
