Yaris burning oil

[Ramon1691]

In only went down a few lines like 3 or so a little down from the full mark I have after 1800 miles with the synthetic also I don't know whether the previous owner kept up with the oil changes that well when I bought it I did a whole tune up on it I'm just going to stick to conventional as you mentioned and just going to keep an eye on the oil every month or so I had my mechanic check the pcv valve and it was good I seen this cars last many miles I also got my serpentine belt done that bastard was full of cracks :/

This stuff slowed my Land cruiser from burning oil.

I just find it hard to believe that this amount of oil burning just happened all of a sudden.

Synthetic still reduces friction wear, regardless of the weather. However, I take your point that if the car is just burning up the oil, you might as well use the cheaper stuff. Like you. I also think it's odd that the car just suddenly started burning oil, and I think that should be looked into.

That's exactly what I would recommend, once the underlying issue has been figured out.

Thank you TARKUS I will use that high Milage oil on my next oil change for now I'll just keep an eye on my oil level since I put conventional back in tho when I changed from the synthetic I noticed that it was really dirty with only 1800 miles on the oil is that normal? Maybe it was all the crap build up on the engine I'm not mechanically inclined but I don't see any leaks underneath or around the motor either

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.

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.

I'm not familiar with the European Toyota engines but as far as I know the 1nz is not an oil burner until the rings eventually wear out.

... 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.

I was told the 2.4 litre Camry would use some oil. Never happened on my wife's one. Maybe only using synthetic oil helps in some way.

No way! That's hilarious. The first green car that burns oil!

yes, synthetic oil should prevent or slow ring deposits.

not really, it burns much less gasoline compared to other oil burning toyota cars (i personally had an oil burning corolla, LOL).

now, 3rd gen prius is speced for 0W20 synthetic oil. i suspect some places cheated and used dino instead. mine doesn't burn oil.
