What is the Difference Between Conventional, Semi-Synthetic and Synthetic Oil?

If you've taken your car, SUV, or truck to an auto repair shop for an oil change or to an auto supply store, you may have to pick between conventional, synthetic, or semi-synthetic oil. Depending on your vehicle’s engine and the manufacturer’s recommendation, your vehicle may have a preference for one. These types of motor oil have different chemical compositions and offer various benefits:

Conventional Motor Oil

Conventional motor oil is the most traditional type of engine oil. It has been around for ages. Nowadays, they are best for later-model, light-duty vehicles with simplistic engine designs. Conventional oil has the cheapest price point, and it will do the job right every time. You can expect to change this oil more frequently.

Full Synthetic Motor Oil

Fully synthetic motor oil is a newer type of engine oil with additives that is more resistant to oxidation and higher temperatures. As a result, it will lubricate your engine components for longer periods. If you have a newer vehicle with a modern engine design, synthetic oil is probably recommended for you. Though fully synthetic oil is more expensive than a traditional oil, the benefits are justifiable. In some cases, this oil can last you up to 10K miles.

Synthetic Blend or Semi-Synthetic Oil

Partial synthetic oil is exactly what it sounds like. You get the best of both worlds – the cheaper price of conventional oil and some of the additives and longevity of fully synthetic oil. It is priced in between conventional oil and synthetic oil.
