I have an 04 2az-fe with 209k miles
Mostly highway....I try a lot of oils depending on what I can get cheapest.
I burn about 1.5 qts in 5,000 miles with valvoline maxlife 10w30 API SN RC
I burn about 1 quart in 5k miles with Quaker State High Mileage 10w30 API SN RC
...Burn about 2 quarts in 5 k with pennzoil platinum 10w30 API SN RC
But the oils I had the LEAST consumption was...
Mobil 1 high mileage 10w30 API SN/SM
&
Quaker state UD Full Syn 5w30 API SN RC
Both of the above mentioned burned less than 1/2 a quart in 5k miles
Hope that helps...
