Yes, you can switch from Pennzoil to Valvoline. Both companies make high-quality motor oils that will protect your engine. However, there are a few things to keep in mind when switching brands.
First, make sure you check your owner’s manual to see if the oil change interval is different for each brand. For example, Pennzoil recommends changing the oil every 5,000 miles, while Valvoline recommends changing it every 7,500 miles. So if you switch brands, you may need to change your oil more often.
Second, be aware that some engines require specific types of oil. For example, many newer cars have turbocharged engines that require synthetic oil. If you switch from conventional oil to synthetic (or vice versa), be sure to consult your owner’s manual first. Using the wrong type of oil can cause engine damage.
Finally, don’t forget to recycle your used motor oil! Both Pennzoil and Valvoline have programs where you can drop off your used oil at participating locations.
