Engineering guidelines for maintenance are established over all kinds of weather, conditions of use by owner, ambient temperature, and go by extremes we may run into. The best case scenario is to take what they advise and follow that because none of us has the money to test every extreme that is out there. I may fudge on hours or miles at times because I am lazy, but I try to follow approved guidelines.
I recall about 50 years ago I was comparing notes with an older friend on how long should be the limit for oil changes. This was when engines and every thing seemed dirtier, but at that time he went about 10k miles when the standard was 2k miles generally. He said his family station wagon car never was greased and had 140,000 miles on it and still runs like a top. He may have gotten lucky, but I don't think anyone would say he had the right attitude about maintenance even though he had many miles on his car.
Someone mentioned a toilet paper filter. I had an older friend at the time that was really pushing the idea and was fairly convincing but I told him many engineers and manufacturers had their business on the line so why take a chance with some untested by theories.
