Truthfully, if you own a car and know your engine, you probably know what type of oil it runs on best. But there is always room for improvement! Many big brands carry products for specific engine needs, such as cars with high mileage. Perhaps your car’s engine would run better and longer if you switched to a different oil. Always check your driver’s manual and mechanic first. Here are some great motor oils we recommend.
How to Select Motor Oil
When searching for the right motor oil, consider these factors:
- Engine: You must know what kind of engine you are dealing with and the type of oil it requires. You don’t want to pour motor oil for lawnmowers into a motorcycle engine. Always check the product’s description to ensure the oil is correct for your motor. Ask an expert if you don’t know. There’s no shame in that!
- Preferences: If you have found a brand name you trust, it makes sense that you would want to stick with it. However, most brand names carry several blends similar to the motor oil you are used to buying. You never know, you might find something that will better meet your engine’s needs.

It contains less phosphorous and more of the good stuff, including detergents, conditioners, and additives, all of which help prevent engine breakdown.
