This seems to be a common problem for those with Toyota 2AZ-FE (4 cylinder, 2.4L) engines. At higher mileages, oil burn suddenly increases. I first noticed this about a year ago when I checked the dipstick and found the oil barely discernible on the low end of the stick. This never happened previously in such a short period.
Ever since I've kept careful notes. All fills listed below were with Mobil 1 HM 5W-30.
05-17-2012 -- 96987 miles -- drained 2.9 qts -- replaced Purolator filter, filled with 4.0 qts
09-02-2012 -- 99219 miles -- dipstick low, added 0.5 quarts
11-25-2012 -- 101550 miles -- dipstick low, added 0.3 quarts
06-04-2013 -- 105970 miles -- drained 3.2 qts -- replaced Purolator filter, filled with 4.0 qts
How much oil are we supposed to get with a drain and filter change, the full 4.0 quarts?
If yes this means it burned 1.6 quarts over the previous 8983 miles...roughly .178 quarts per 1000 miles.
