  Thank you everyone for your comments.  A number of people have asked for a data as a backup - but you have to remember that when it comes to predicting the durability of engines, the best way to do that is to take the engine apart.  You will then clearly see the residue of the oil, condition of the inner components etc, and often times the condition of the engine itself does not correlate with the condition of the engine oil. So it is very deceiving - and dangerous - to assume that the engine is in good condition due to the good condition of the oil (through data and analysis).  People like AMD from Car Care Nut, myself as an automotive engineer, and Mr. Takumi Kurosawa (Nissan GT-R engine leader) have all taken hundreds of engines apart and correlated the condition to the frequency and type of engine oil used.  That's the best type of "data" and most accurate way to predict the engine condition (you can see it).  Because I have taken apart hundreds and hundreds of automotive components apart, I know exactly what needs to be done to take care of automobile components and parts (not just engine), and my recommendations are based on these experiences.  My two good friends AMD and Mr. Kurosawa will back me and support me as they have the same insights and ideas as in this video.  I hope this helps you understand how I came up with my recommendations.  At the end of the day, you are free to decide what to do based on your own experience and knowledge.  I am simply sharing my insights based on 35 years of working with cars inside and out.

  Great advice on how to make an engine last. Personally I don't care if I'm planning on keeping my vehicles basically forever or if I'm going to get rid of them every 50,000 miles. I'm going to treat every vehicle the same. I want to know when someone purchases something I bought new, broke in, and maintained, that they're going to buy something that could last another quarter million miles. I don't care if that person is a grandkid or some stranger I'll never meet. It's just the right thing to do.

  2007 4Runner. Oil and filter change every 5k and transmission flush every 60k. Currently 343k miles. Runs and drives as good as the day I got it. Burns no oil, no leaks, transmission is milky smooth. Wouldn’t hesitate to jump in and drive it from Georgia to California and back. Just a great vehicle made in a place where they value work ethic.

  In a previous job I got to visit the lab where a very well known brand of oil was formulated and tested. The chief engineer told me that if I wanted to have virtually zero engine wear I should take the recommended service interval and halve it. So 12k miles becomes 6k and so on. I followed his advice and my last car was 19 years old when it had to be scrapped due to rust. But the engine still ran like a sewing machine.

  I have a friend that recently traded his ford f250 diesel for a new one because he had about 225000 miles on it. He never once changed his oil. Added some oil from time to time. I have a 2023 Lexus GX 460. I only have 25,000 miles on it and have changed oil three times. Still trying to decide if I will change it every 10,000 miles or 5,000 miles.

  You know the Car Care Nut is a reputable Toyota master mechanic when a 35 yr experienced auto engineer mentions you in his video as a reference.

  Own two Lexus, 17yrs old and 13yrs old.  Change oil and filter every 6mths or 5000miles, with mobile 1 full synthetic.  No engine problems at all, to include no oil burning.  I use the same interval for my son’s Prius Prime.  Other than 1 hr of time, the cost for oil change is about $40 (I do my cars oil change. Can’t trust jr. Mechanics). That’s cheap for worry free engine.

  First thing: manufacturers recommendation on severe service schedule is my baseline. I typically do a 5k mile OCF using whatever synthetic OEM spec oil I can get on sale, a high quality filter, and the occasional lab analysis. I also do other fluids at 60k for trans, 90k for coolant, and brake fluid every three years. Service on 4wd transfer case and differential is approximately every 30k - 50k depending on the component. I’m not afraid to go longer on the OCF if on a long over the road trip and have done an 8800 mile change with lab analysis showing the oil still held additives and no degrading wear byproducts. Excellent summary sir. Grease is cheaper than steel.

  Urban vs freeway driving also makes a difference to how often I'd change the oil.

  Number one debated topic on any motorized vehicle forum.<br>1. Brand of oil.<br>2. Frequencies of oil and filter changes.

  Run full synthetic. &nbsp;Change ever 5,000 miles. You can&apos;t go wrong.
