Is generic oil as good as name brand?
Many lesser-known brands offer products at a fraction of the cost of name brands with little to no impact on the quality of the product. Is there actually a physical difference between generic and name brand motor oils? The answer is YES!
A premium synthetic will protect against wear and be more resistant to heat degradation so again, if you’re racing, towing or have a high performance engine, it’s worth using. Regular people with regular engines won’t really benefit.
Does it matter what oil you buy?
There is no objectively “best” viscosity, or weight, for your motor oil. You should use the motor oil viscosity your car’s owner’s manual recommends. If you have gone through the expense and trouble of buying a high-performance vehicle, you should utilize fully synthetic oil and oil additives.
Is there really a difference in oil brands?
As long as the oil weight and certifications match what your car needs, there is no point in paying extra for a brand name. The answer is… they’re all interchangeable so long as they meet the oil weight and certifications for your vehicle.
Does motor oil brand really matter?
No. Switching brands is not harmful to your engine as long as you choose an oil marked with the API donut of the same level, e.g., API SN. You may give up enhanced performance if you switch from synthetic or high mileage to conventional oil. MYTH: When motor oil becomes dark, that means it’s time to change it.

Is there any difference between brands of synthetic oil?
