I've looked around the site and have done a little research as to why my car eats a quart of oil in 3000 miles. Some say its a common thing and some have larger issues such as valve seals or something along those lines.

So how much oil is your celica running through and how long have you gone now with it?

my oil gets close to empty after 1500. i heard if you use thicker oil it wouldnt be such a problem
