Why do Toyota engines consume oil ? And how to prevent it?

easy, don't buy a toyota

 

Weird thing is, I’ve got zero consumption at 90k kms. All our previous Hondas has minor consumption; I thought that was the norm.

Per the video, I am following the Toyota Canada 3rd gen spec for oil change: 6 mo or 8k kms (5k miles). And it’s always months these days...

For 4th gen they’re in lockstep with Toyota USA.

 

If a car used absolutely no oil, I'd be concerned.

We've had a number of TOYOTAs - no oil use - might drop a little on the dipstick between changes - but never had to add oil.

Unlike some other cars we had - MITSUBISHI (had 3) was the worst, VW (2) not much better.

 

I've always changed my oil more often than called for. I've never had an oil burner.

Edit to add that I'll be changing my wife's Prius Monday, most likely. Her Maintenance Required message just started blinking. She has now had the car for almost 5,000 miles.

 

I just remembered another car which burned oil - VOLVO 244. But then, I bought it 20 years old with 350,000kms.

 

Our 2 Tesla's burned very little oil

Couldn't find a reference to "our" 2ZR engines. Did I miss it?

 

yep sometimes .... unlike safe, renewable, non-toxix, gasoline burners.

Our higher mileage gen3 engines burn oil due to a design error. As do earlier 2006 through 2011 standard engines, most commonly Camrys. Some say it was an ill conceived strategy to increase mpg through changes in the piston rings.

My 2012 v did not burn oil until well past 100,000 miles (160,000 km for Canadians) and the factory "recall" level of one quart every 1200 miles was not met until more recently, probably around 200,000 miles (320,000 km). So I place little credence on a car's resilience when they are under 150,000 miles.

In my case, it was full synthetic changed more often than specified. However our Central Texas roads are usually 70 mph two lanes, 80 mph freeways and 85 mph (legal) tollway speeds, all with ac humming.

The best thing to do is change the oil every 5k miles and keep the engine loading lower by avoiding >70 mph for extended periods.
