oil consumption

[anne marie]

hi i'm new to this forum, i have a corolla 2003, do they suffer from excessive oil consumption after 100,000 km. i've heard through a mechanic friend that the 1.8 corolla engine has a oil control ring that isn,t up to the job. does anypne know of this problem. i'am a bit worried as my car has done near that

My mum's 1zz has 130k on it without any issues. CAn't say I have heard of this problem myself, but I don't look into 1zz stuff with much detail.

I've never heard of this either...

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.

My 1ZZ Corolla is over 100,000kms and it does not use excessive amounts of oil :) usually have the oil and filter changed every 10,000kms and it hardly burns any at all.

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
