I’d recommend full synthetic. It costs more, but you can usually get at least 7,000 miles between changes and it’s
Also cleaner with less impurities that can accumulate in the engine.
Conventional oil isn’t bad, but synthetic is a better product.
Just make sure you keep track of your oil level occasionally with more time in between changes to make sure your oil level doesn’t get low.
And make sure it’s full synthetic, not synthetic blend.
