hmmm, i've never heard of this. I doubt it would be using excess oil after only 100,000k's.. If you really are that worried, ask a few different mechanics..

I'm sure someone else will be able to give you a good answer here anyhow.

in DK it's a big problem..

People that drive short distances. or cold start a lot. have this problem

A few 3zz-fe and almost all 1zz-fe 2000-2005 toyotas have this problem.

The problem is the lower piston rings. "oil-rings" Normally the piston have aprox 12 small holes in the pistonring gab.

Toyota forgot about them and made 4 small holes. when the oilring needs to scrabe oil off the cylinder. passes the 2 upper rings and u get oil Consumption. starts with a littel but ends out ind wery sticky pistonrings..

Toyota made a new block with 8 bigger holes in the pistons. Starting from 2005
