Types of Bulk Motor Oil

As a wholesale motor oil distributor, Motor Supply Co. offers all motor oil types for all engine types.

Motor oils fall into one of five categories: full synthetic, synthetic blend, high mileage, conventional, and heavy duty. Each type has its own unique characteristics that benefit certain engines and applications.

Full synthetic motor oil is chemically engineered to provide uniformly shaped oil molecules and performance-enhancing additives. Synthetic motor oil performs better under extreme high and low temperatures and is ideal for modern and high-performance engines.

Synthetic blend motor oils rely on a mixture of synthetic and conventional base oils. These oils provide more oxidation resistance than conventional oil while maintaining excellent low-temperature performance. Synthetic blend motor oils may also include detergents to help reduce sludge formation and extend engine life.

Vehicles with a few zeroes on the odometer (or those with over 75,000 miles) can benefit from high-mileage oil. This motor oil has additives that can reduce oil consumption and even prevent leaks that are common in older engines.

Conventional motor oils are derived from crude oil and come in a broad range of viscosity grades. These oils are designed for simple engines and moderate driving styles.

Diesel engines can be prone to deposit build-up and oil thickening. Heavy duty motor oil helps keep diesel engines cleaner, extending engine life and protecting against viscosity loss.
