Yaris burning oil

[tmontague]

If you Yaris is burning a Liter every 1k and you have just over 100k km on it then you need to check your PCV valve. A healthy Toyota engine does not and should not burn through oil at that mileage.

If you had well over 300k km and it had a hard life (traffic, tough climate) then burning that oil would be considered expected.

When my engine gets to that point i'll be tossing in a 2zr but I have 155k km on my engine and zero oil consumption. That is with an engine driven hard but meticulously cared for and 13k km oil change intervals on 0w30 synthetic (as per a used oil analysis).

I don't expect to be seeing any oil consumption until. Well above 250k km.

Remove the PCV valve every oil change and spray it clean with some brake or throttle body cleaner so that it rattles freely when shaken.

Thanks for all your suggestions in so glad I found this forum, I changed my oil today with Mobil 1 conventional oil premium and put a new filter in as I didn't change the filter last time and I replaced the pcv valve see if that helps

Mines done 110k miles. So that's like 165k KM?

I checked the PCV valve just out of curiosity. It was removed and cleaned for the service last year. It was still clicking. I don't think it was blocked. Cleaned it out with some brake clean anyway just to make sure.

All Toyota engines burn oil. Mine has been pretty well looked after. Oil changes with the yearly 10,000 mile service. It does do a lot of motorway miles which I not sure the 1KR engine was really designed for. My sisters Yaris with the 2SZ burns oil at around 1 litre every 2000 miles. Its only done 60,000 miles. She's only put 10,000 on it in two years.

In any case I just plan to drive mine till the engine blows up or until its burning a litre every couple hundred miles. I might do an engine swap or a quick and dirty rebuild.

... All Toyota engines burn oil.

1 mile = 1.6km

I have to disagree with your statement about Toyotas burning oil. I would say no more than most other modern cars, possibly less.

My previous 2004 Echo RS (ie Yaris Mk 1) was using hardly any oil at 230k km. My wife's 2006 Camry is also at around that mileage and not needing top ups between services. Likewise, for my current 2006 Yaris with 150k km. Oil consumption is normally minuscule with these cars, so long as they've been looked after.

they do burn more then they should. corolla/celica/MR2 affected big time (98-03 in US and even later years in europe). Camry and other cars with the 2.4L engine affected till 2009. Reports of prius oil burning, especially 2010.

my theory is low tension oil rings get gummed up easy and quickly. engine flush can help when done early on.
