There are many types of mtor oil out there to choose from, but how do you know which one is right for your car? Of course you can take a look under the hood and see if there is a sticker or label somewhere to tell you, or you could read your owner’s manual and see what the manufacturer suggests. But what about those of us that want to learn more about the oil that we put in our car’s engine? We here at GIC Car Clinic feel the same way you do so we decided to put together this brief tutorial to teach you something about motor oil.


  • Oil viscosity is basically, the thickness of oil. It is very important to choose the right viscosity of oil for your car. If it is too thick or even too thin, it could do severe damage to your engine. The older your car gets, the more viscosity it will need in its oil. This is mainly due to the wear of parts over time and an increase in friction.

Oil Grade

  • The oil’s grade is the set of numbers you see on the container. The higher the number is, the higher the viscosity of the oil will be. You may see an oil labeled, 5W30. The 30 denotes the oil’s viscosity while the W shows that the oil meets a specific low temperature requirement.
  • On the shelf you will see three basic types of oil: conventional, synthetic and synthetic blend. Any of the three are good choices for your engine. Conventional oil is an organic oil and is highly reactive to temperatures whereas synthetics are not. Synthetic oil is designed to give you better performance and cooler operation.
  • Synthetic blends are a mixture of both conventional and synthetic giving you the best of both worlds. There is also oil specially formulated for higher mileage vehicles which contains special additives to help keep your car on the road longer.

If you are still unsure about which type of oil to buy, call us up here at GIC Car Clinic and one of us can help you choose the right oil for your car.
