Regular Oil only goes 3,000 Miles. 100% Synthetic AMSOIL goes 25,000 miles on the same oil and filter as well as giving you a 6% savings in fuel.

For your 2005 TOYOTA RAV4 2.4L 4-cyl Engine Code 2AZ-FE You would need:

4 Quarts of SAE 5W-30 Signature Series 100% Synthetic Motor Oil (ASLQT)

1 Absolute Efficiency Oil Filter (EA15K09)

Most of today's oils will be good till 7000 miles. But I'm old and stubborn so I still do 3000 mile changes so split the difference and you'll be fine

3000 miles. Gasoline vapors break down the oil.

4 to 5k miles is fine, in normal driving conditions. 3k miles is simply overkill.

Hi. I have a Toyota Rav 4. Last time I got an oil change it was with regular nonsynthetic 5w-30 oil. Do I have to get an oil change at 3000k or can I wait 5000k even though I'm using regular oil? Thanks!
