Does engine oil expire?
Valvoline engine 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 API/ACEA 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 to shake the container before use to blend any additives that may have settled.
Does engine oil ever wear out or does it just get dirty?
Yes, engine oil does break down. Oil additives are consumed and combustion byproducts build up in the oil. Changing your oil on a consistent basis removes combustion byproducts and replenishes the additives.
Can engine oil improve horsepower?
Yes. Special oil formulas with friction modifiers and special additives help to improve or restore horsepower. Lower viscosity (lighter) oils can improve horsepower providing that they separate moving parts and maintain engine durability. The optimum oil viscosity for a given engine is specified by the automotive manufacturer.
Is it ok to switch engine oil, for example, from a 5W-20 to a 10W-30?
It depends. Some vehicle manufacturers provide a range of recommended engine oil viscosity grades based on the outside temperature in which the car is driven. Other manufacturers recommend the use of only one oil viscosity grade. For best engine performance, always follow the manufacturer's recommendations found in your vehicle’s owner’s manual.
Is it ok to use 5W-30 in a car if the owner's manual calls for 5W-20?
Valvoline 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 viscosity and maintenance schedule provided in your vehicle's owner's manual.
What does the "w" in a grade of engine oil stand for?
The "w" in engine oil viscosity stands for winter. The first number in the oil viscosity 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- engine oil will flow better at lower temperatures than a 15W- engine 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.
Is thicker oil better?
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 engine oil viscosity in your vehicle's owner's manual.
What are the benefits of using racing oil versus regular passenger car oil?
The Valvoline VR1 Racing and other racing oils are not intended for passenger car vehicles. They contain additional additives for increased horsepower and reduced friction on metal parts, provide extra wear protection for high compression/higher horsepower engines, and include fewer detergents than regular conventional oils.
What is engine oil with zinc?
The anti-wear additive simply referred to as zinc by most car enthusiasts is actually short for Zinc Dialkyl Dithiophosphates or ZDDP. Its primary role is to prevent metal-to-metal contact between engine parts by forming a protective film. Despite being referred to as zinc, ZDDP also contains phosphorus, which helps to perform the anti-wear function in the engine oil.
Why are zinc/phosphorus levels in engine oil lower in today’s engine oils?
With ever increasing limits on emissions, automobile manufacturers have tightened emission control systems on newer vehicles. This is one of several factors considered when automotive industry organizations like API or ACEA set standards for engine oil with zinc. Because phosphorus can poison a vehicle's emission system, the level of zinc is lower for current engine oil. Valvoline uses a new type of zinc/phosphorus that maintains the prior level of wear protection of the engine while reducing the impact on the emission system.
