This is a discussion that serves two purposes... Both have something to do with mileage.
1) How many miles on your EJ22, and how has it held op to the test of time?
2) What kind of mileage (MPG) do you get with the EJ22?
I have 154K miles on my car, soon to be 155K. Since I bought the car at 138K I've replaced the spark plug wires, spark plugs, battery, battery cables, accessory belt, transmission fluid and filter, muffler (Twice), air filter (3" cone), some vacuum hoses, CV Shaft, rear struts, rear strut mount, radio, brakes, a fender, speakers, and other minor stuff. I also got an alignment a while ago. The car needs a lot of body work and new inner tie rod ends. Soon, I hope to get rebuilt fuel injectors, a catalytic convertor, MSD ignition swap, and O2 sensors.
As far as mileage, the car supposably got 18/22 from the factory, but I'd say it's more like 20-25 on average. I'd say if I drove like a grandma all the time I'd probably get 25, but that's never going to happen.
