Pennzoil Conventional Motor Oil uses a traditional oil base fortified with Active Cleansing Agents to continuously prevent dirt and contaminants from turning into performance-robbing deposits. This advanced formulation helps keep engines clean and responsive by cleaning out sludge with the first oil change and maintaining cleanliness all the way to the next oil change. It is specially designed to provide extra protection against the harmful effects of stop-and-go driving as well as high and low-temperature engine operation. This motor oil can be mixed with other synthetic and mineral oils and is for use in all vehicle applications under all driving conditions.
