While you seem to be trying to toot your own "smart" horn here in this thread, you are far from the only engineer who has a lot of experience and knowledge. While the MM algorithm may not be all-encompassing, it certainly is much more intelligent than "change your oil every 3,000 miles" or "once a year". I happen to know people who have their oil tested regularly and get 15-20K per oil change under varying conditions, so the MM is very conservative by any account.Irregardless of MM engineers etc tell you to change oil up to two times a year. Absolutely once even if only drove few miles.
In my Gen 1, I changed between 7,500 and 12,000 for the most part, and never had an issue. Nor does the 2nd owner (wehave stayed in touch).
Also, irregardless is not a word.
As am I. And so is @zroger73. Not sure what your point is?Yes I am referring to my own education and work experience. I am, well out of respect I'll say should be, as qualified as any other that wrote those papers.
Not sure who you are arguing with about gas mileage, but I regularly got over 25 mpg on my Gen 1, and easily hit 30-32 mpg on my Gen 2 on the highway. Typical in town for me is 16-18 on the Gen 2. Also, bear in mind that the computer typically shows 2 mpg higher than actual.Many said the best gas mileage with their (older?) Ridgeline was well below 20 mpg. Then I stated confirmed mpg i got was 30 with constant effort to get 30 or above and all I got was attacks. I got 2021 Ridgeline (at 3,000 mile mark and tired of it and its limitations) and on equal up down hill highway I get 30 mpg Min. Perhaps ppl are told not to expect more than 14...20... just like with the oil and MM.
Two questions for you:I know I must rub people the wrong way, however, there really is solid science to what I stated.
A) Is English your first language?
2) What is this "solid science" you claim to have to back up your claims?
Correct. Oxidation is not nearly the issue with synthetic oils that is was with dino oils. 2 years vs. 1 year with low miles for oil changes.Oxidation is NOT a limiting issue any longer in modern oils and engines.. Not sure what data “engineers” are telling you to follow but changing your oil too often is as blindly misguided as too infrequently. Guessing,hoping,reading isn’t science.
