A Toyota Master Diagnostic Techncian discusses Why do Toyota engines consume oil or burn it. And ways you can prevent it from happening to your Toyota

In this video I go over a very hot topic, Toyota engines burning oil? Not only the 2AZ-FE engine that was part of a customer support program and was fixed because of a problem. But the newer engines are also using oil like the 2.5L 2AR-FE , 2.7 1AR-FE and the 2ZR-FXE 1.8 engine in the toyota prius.

I will go over what is causing all this mess and you guessed it. Low tention piston rings. This is a change that took place in modern engines that makes them very tempermantal to oil maintenace.

The No.1 cause of oil burning problems in modern engines not just with Toyota but with everyone is low tension piston rings sticking or seizing because of bad maintenance habits.

Toyota's 10,000 mile oil change or 1 year is great to reduce the costs of ownership. However you must adhere to the strict guidelines for this oil change. There are many condtions which would change your car to Special operating conditinos which would then call for a 5,000 mile oil change or 6 months whichever comes first.

I wish all my viewers and everyone who watches this video to know about this and understand that going into the grey area of special operating conditions is not worth it. Toyota overall maintenance costs are very low even with the 5,000 mile or 6 month oil changes. Why push your engine to the edge or keep wondering if you operated your car in special conditions, Just do your oil change every 5000 mile or 6 month and wonder no more.
