Frequently Asked Questions (FAQ)

BRAVOIL does not recommend doing this. Using a heavier grade than recommended may cause decrease in fuel economy, higher engine loads and eventually shortened engine life. Using a lighter grade than recommended may result in excessive mechanical wear and reduced engine life. For maximum engine performance, follow the recommended motor oil viscosity and maintenance schedule provided in your vehicle's owner's manual.


In some circumstances, thicker oil can be used to compensate for increased bearing clearances (gaps between bearing and rotating shaft) that have developed over the years. A large change in bearing clearances can result in poorer lubrication. For best performance always follow the recommendations for motor oil viscosity in your vehicle's owner's manual.

The "w" in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature

Straight weight oil is never recommended for use in a system that requires a multi-viscosity oil. Straight weight oils are generally recommended for smaller engines or older vehicles that were made before multi-viscosity oils were produced.

Conventional, synthetic blend, synthetic and high mileage motor oils are compatible and will not harm your vehicle's engine. For maximum engine performance, follow the motor oil type recommendation provided in your vehicle’s owner’s manual.

BRAVOIL motor oils do not have documented expiration dates. When stored under optimal conditions, the product remains stable for an extended period of time. It can be used as long as the American Petroleum Institute (API) rating on the label continues to meet or exceed the requirements listed in your car’s owner's manual. If the rating is still current, we advise you shake the container before use to blend any additives that may have settled.

Yes, motor oil does break down. Oil additives are consumed and combustion byproducts build up in the oil. Changing your motor oil on a consistent basis removes combustion byproducts and replenishes the additives.

BRAVOIL recommends you replace the oil filter with every oil change, as this will eliminate any risk of contaminants trapped in the oil filter (e.g., dirt) from re-entering the new oil. Always be sure to follow the oil change frequency recommendations in your vehicle’s owner’s manual and to use an oil filter meeting automotive manufacturers’ guidelines.

All BRAVOIL motor oils with the starburst symbol help to reduce fuel consumption.

Yes. BRAVOIL lubricants are fully compatible with mineral or synthetic oils. No special procedures are necessary when switching to BRAVOIL.

However we do recommend doing a complete drain and fill as opposed to doing a partial top off on top of some other companies oil. We recommend against mixing different product lines or brands of oils from different companies, as it is not considered a best practice. Additive conflicts can occur in some cases when dealing with large quantities of mixed dissimilar engine oils.
