Also, consider that even though motor oils contain the same essential ingredients, they each have different additives, chemical properties, and detergents.
Mixing different types can destabilize your motor oil, reducing its efficiency and affecting your engine's performance. The smartest choice is to stick with the oil type and oil change intervals recommended by your car's manufacturer and visit your local car care experts for affordable services.
It's important to keep oil at safe and clean levels to avoid engine trouble. Many people do this by topping off their motor oil in-between oil changes. This is often how motor oil types get mixed. While the occasional oil top-off is usually okay, getting an oil change is always the best way to keep your engine running smoothly.
If you must top-off your oil, try to use the same type that's already in your vehicle to avoid losing any of its benefits. As always, double-check your manufacturer-recommended service schedule or visit a Tires Plus location to get all of the service and oil type recommendations with none of the pressure.
Are you thinking about changing to a different type of motor oil? Switching is easy! Visit your nearest Tires Plus location and ask for an oil change with the Pennzoil oil of your choice. If you're not sure what kind of oil might be best for your car, our certified technicians are ready to answer all your questions.
Blog Categories Blog Home. The short answer is…yes. It is thought to have created seal and gasket leaks on older cars, but modern technology ensures the two oils have enough similar properties to prevent this from happening.
In almost all cases synthetic oil is the best product for your vehicle. It is higher-quality and doesn't contain the impurities found in regular oil. It has a higher viscosity rating as it is much better at handling extreme temperatures, both high and low. Viscosity changes as an engine heats from cold to very hot, oil thins, and the properties alter.
High viscosity oil is thick and runs slowly, low viscosity is thin and runs faster. There are a set of quantifiable characteristics of lubricants that the industry adheres to. Viscosity is one and describes and rates a fluid's resistance to flow. Viscosity defines the force required to pass a 1-layer of fluid through another, at a given speed and temperature.
The rating is shown as 2 numbers which are achieved by testing the oil at 2 given temperatures, hot and cold, 0-degrees F. Oil with a 15W 40 viscosity rating acts as if it were 15 when cold and respond as 40 when hot. Multi-viscosity oils provide the best protection for an engine through a range of extreme temperatures.
If you choose an inexpensive oil it should protect your engine well at 'normal' temperatures. Once the temperature goes beyond these parameters the oil will not behave as you would expect, it will become decreasingly effective and cause excessive wear and tear on the engine.
Synthetic oil, unlike conventional oil, is made up of molecules of a consistent mass, size, and shape. The oil flows better in cold weather enabling reliable, cold weather starts and smoother running in winter. Conventional oil breaks down or the molecules evaporate at extremely high temperatures.
This causes metal-on-metal contact, creating friction, excessive heat resulting in damage and wear and tear. This doesn't happen with synthetic oil as it resists viscosity changes in high temperatures.
It is a slicker consistency, which ensures smoother and cooler engine operation. However, it should be noted that engines with existing leaks might mind the slickness of the oil exacerbates the leaks, resulting in burn-off and blow-by. Synthetic oil is by far the most expensive option. This can be offset by longer intervals between oil changes; often vehicles can run for double the distance expected from conventional oil.
Some industry experts suggest that a clean, modern engine run purely on synthetic oil, only requires a full drain at mile intervals. Diesel engine oil is more viscous and contains more zinc than gasoline oil.
This is due to the different types of catalytic converter a diesel engine has. It is not likely that you would form gel by mixing the two oils. However, we would not recommend mixing oils as a general practice because oils are complex mixtures of additives and base oils that can be destabilized.
