How often should I have the oil changed in a 2017 Toyota RAV4?

If you're using regular motor oil every 3,000 miles. If using synthetic oil every 5,000 miles. Make sure you check the oil level on the dipstick every 1,000 miles between oil changes and keep the oil topped up to the upper dipstick mark.

Toyota has a "maintenance schedule for idiots" in the warranty and maintenance addendum to your car owner's manual.  Go to the Toyota website and look at this addendum.  Click on "Owners", then "Manuals and Warranties".  Good luck.

FIRAST realize that NOT ALLOILS ARE THE SAME or lst as long as other oils do! NEVER EVER EVER use B VAL:VOP:IONE an oil GUARANTEED to make SLDDUGE< ASH, WAX< and even COKE dpsotis inyour ENGIEN RINGG! It is refinced the ODL FASHIONED WAY and x comes from ASH and WAX! USING PENNZOIL ULTRSPLATINUM OIL< a FULL synthetic nade fro NATURALGAS qwill get you a warranty to 500,000 mieswith on ly ONE CHANGE pere YEAR! If you EVER USED VALVOLLINE you may NOW need a llight SLUDGE REMOVAL treatment!  IT is LOUSY LOUSY OIL AND I SUED them and WON Long ago! I SUED CASTROL as well! PENNZOIL protects the ENGIEN< the BEARINGS< the SENSORS fro ACIDIC VAOPR rotting! VALVOLINE ROTS rubber brether hoses with ACIDS and also cause the RINGS to gather BAKED IN SLUDGE and COKE! it isUSELESS in TURBO CARS! And SHOLD BE OUT OF BUSINESS! If the dealer you go to carries VALVOLINE (ASK THEM) walk RIGHT OUT AGAIN. They get DEALS to lubriacte the POWER LIFTS! I got a BIONUS for teliing my boss at a SAAB dealershhip that VALVOLINE was DESTROYNG TURBO CHARGERS.>>>BACK to your QUESTION! The use of PENNZOI LULTRA PLATIUM will extednt eh OIL CHANGE interval to ONE FULL YEAR! AMSOIL synthetic says 25,000 miles with ONE FILTER CHANGE midway! I used ONLY PENNZOI LONG LIFE in my two AUI TURBOS and NEVER had a LICK of trouble! PENNZOIL is THE oil  of FERRARI aas well! IT handles HEAT without making TAR and WAX or ash The WARRANTy is UNREAL! it priotecgts engien rings frmo SLUDGING UP and TARRY over! tehy will remain as CLEAN as the DAY the vehicle was MADE! ALSO ther is TOTAL ENERGY OIL and LIQUI MOLY< but only PENNZOIL gives tha WARRANTY length! ASK THE  TOYOTA  DEALER which OIL they ae USING! Say NO to valvoline! This is NO JOKE! it an ROT GASKETS and SEALS and it WILL dissolve PENNZOIL protects to 35 BELOW ZERO! THIS is a NO BRAINER! THE FIRST itm eyouuse PENNZOI LULTRA, check the dipstick in a few WEEKS! If it is VERY VERY dark brwon , there a was a LOT of BAD USED! Wait anothe rMONTH and then CHANGE IT AGAIN! It is only $20 for FIVE QTS at WALMART!    

When in doubt, follow the recommended service intervals as outlined in the owner's manual.

3 to 5 thousand is now recommended, depending on vehicle, driving, and oil used and such. Currently with driving limited due to shutdowns, go by opposite seasons. Fall and spring or winter and summer. As opposed to mileage.
