Read on for a comprehensive list of frequently asked questions that will provide you info on choosing, using, and maintaining motor oil for your engine.

What’s The Difference Between Motor Oil Types?

Motor oils typically come in one of three types:

  • Traditional Oil: Made from refined crude oil, it’s the most affordable option.
  • Full Synthetic Oil: Chemically engineered for better performance and longer life.
  • Semi-Synthetic Oil: A blend of both, offering a balance between cost and performance.

What Kind Of Engine Oil Lasts the Longest?

Full synthetic oil lasts the longest. It resists breakdown better than traditional or semi-synthetic oils. This makes it ideal for high-performance engines or longer oil change intervals.

How Often Should I Change My Oil?

The frequency of changing your motor oil depends on several factors, including the type of oil used, your vehicle’s make and model, and your driving habits.

Most manufacturers recommend changing your oil every 5,000 to 7,500 miles using either a synthetic or synthetic blend. Older high mileage vehicles, or vehicles that use conventional oil, may need to have their oil changed every 3,000 to 5,000 miles.

What Happens If I Put the Wrong Oil In My Engine?

Using the wrong oil can harm your engine. It may reduce performance, increase wear, or void warranties. Always check your owner’s manual or ask a professional to ensure you use the right oil.

Do Diesel Engines Require A Different Type Of Oil?

Yes, diesel engines need oil with specific additives. These handle higher mechanical forces and soot levels. Look for oil labeled for diesel engines to protect your engine and improve efficiency.

What Makes Motor Oil Go Bad?

Motor oil degrades over time due to several factors, including environmental conditions, engine operations, and contamination. The most common factors include:

  • Contaminants like dirt, grit, and debris
  • Thermal breakdown from heat and engine load
  • Age – oil tends to lose its additives and viscosity as it gets older
  • Sludge formation due to contaminants and prolonged use

Can I Mix Different Types Of Engine Oil?

It’s not recommended to mix different types of oils. While it won’t cause immediate damage, different oils may have incompatible additives or types of viscosity. This can reduce performance and protection.

How Much Does Motor Oil Cost?

The cost of oil varies by its type and additives but typically falls in the following ranges:

  • Traditional oil: $3-$6 per quart.
  • Synthetic oil: $7-$15 per quart.
  • Blended oil: $5-$10 per quart.
