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

  I worked for a car manufacturer for almost 3 decades. Every engineer from power train group I ever worked with was not favorable to long drain intervals. The environmental impact of waste oil and competitive pressures for low maintenance costs pushed their managers to do it. The reduced water jacket height in block and oil spray jets allowed oil to get to evaporating temp for fuel and moisture and better oil all got them to the best result. THEN reduced friction was the goal and ring width and spring force were one the first and easiest things to do to reduce effort needed to turn engine over. High output demands then got us turbochargers. The ring heat and more plastic like particle formation got the ring groove sludge build that sticks rings. The basic indisputable fact is that ANY oil gains contaminants with engine use hours. Dirt particles smaller than air filter capture size and fuel that is not combusted that is on cylinder walls and is scraped down by rings will accrue in the oil. Synthetic oil is better at tolerating this but it is still oil and still accrues the same stuff. Superfine bypass flow oil filtering can get the particles but still you have the other dilutes building up. As stated, ONLY MORE FREQUENT OIL SERVICE fixes this. So you buy a prepaid maintenance plan and it only covers the standard schedule? Find a trusted quick lube and get the base service oil change. If you keep the car it will pay it back. Even without ring concerns the overwhelming bulk of vehicles have timing chains and variable cam timing. Those c omponents suffer from the dilutes in oil causing wear not seen in 150K mile engines with more oil changes done. Camshaft in hemis, tappets in GM V8s, and cam phasers in some Fords? Not seen much at all when the oil changes were done at 5K interval. Listen to Car Care Nut

  As Scotty Kilmer says, "oil is cheap, motors are expensive".

  I have been an auto technician for 47 years. I have been telling people for years to change their oil and filters more often than the factory recommends. All the engine work I have done( like rings and bearings) were because of not changing the oil enough. Can't stress this enough.

  I've always changed organic oil at 3000 miles, 5000 on synthetic oil. I have never had an oil consumption problem or any major engine failures. I do not drive anything easy. I believe it's better to "beat on them" a little cause it's good for the engines. My son was using Amsoil and went by their recommendation of change oil at 12000 miles, change the filter again at 6000 miles and add a quart. He had 3 cars that had crankshaft failures. These were engines that never had crankshaft problems. I kept telling him that's way too long on an oil change, he finally gave up on Amsoil and changes his oil at the same intervals that I do, so far no problems. I've been a mechanic for a long time, I've seen it all.  Good video.

  One can tell that this guy is a great mechanic and it's telling the truth by how frustrated he is.

  I’m a mechanic and this guy speaks 100% truth

  In the 1960-70’s mechanic Smokey Yunick wrote a column in Popular Science magazine.  I’ll always remember what he wrote;  “He who spends the most money on lubrication goes the furthest the cheapest.”

  Too many people take advantage of Toyota’s reliability and ignore maintenance and expect them not to have a problem.

  I've had my car for 12 years from new.  I'd always changed the oil and filter every 5000 miles with mobil 3000 and OEM filter.  The car now has 100000 miles on it, I just inspected the cylinders with an endoscope.  Still has the cross hatching and very few faint vertical scoring.  Listen to the guy, he knows what he's talking about.

  My Toyota dealer refused to change the oil at the first 3000 miles. Now I get cards in the mail saying- WE Miss You.
