Just pick up my new 2020 Rav4 XLE for $24000. How often do you think I need to change the Oil?
Congratulations on your new car!
Look up the service section of your owner’s manual. It should give you all the fluid change intervals.
It all depends on driving conditions you will be encountering. Mainly city? Mainly highway? Short or a long trips? Also, local conditions, … are you down south - mostly warm weather, or up north - winter snow and sleet 1/2 of the year? Your car came with an owner’s manual, … it has a recommendation for ”normal" conditions, … will you be using your car under normal conditions?
And so, adjust your oil changes for your normal! And remember: … use, exclusively, only 0W-16 oil. Only! Oil is cheap, … a sophisticated (German-like!) engine is very expensive!
F.S.
Every new car owner should read owner's manuals, and even sales advertising, to know what the manufacturer says responsibility, duties and accessory operation is.
If you want to keep your warranty, follow directions in the owner's manual. I change my oil and filter at 3000 miles max, but that's because I want my engines to last hundreds of thousands of miles and oil is cheap compared to an engine.
