Synthetic oil change every 10k?

We're not exactly dealing with a high performance engine thats got a turbo or supercharger that needs those extra high quality synthetics. Any of the general 0w20 synthetics are adequate in our 3.5's. I swear some always think if some is good, than lots more is better.

 

The oil is just that. It is refined and has additives put in it, it does not come out of the ground and get poured into the crank case that is where the science comes in. Zero viscosity is intended for winter start up only. The refiners have their own ideal as to what else to put in it. 78% is the basic oil the rest are various additives.

 

This guy “oil is oil”

 

I do the Mobil1 0W20 or 0w30 at 5k for Toyota. For Ford and GM, I use 0w40, they seem to like it better. 250K miles with no issues or even oil burning.

This guy has several vids on Toyota engines alone.
Some more stuff to ponder.

"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"

 

Toyota god has spoken.....how many videos did this guy make? Does he even have time to work on Toyota's anymore?

 

He has is own shop in IL and employs two mechanics. Yes, he still gets his hands dirty.
