Agree the internal combustion engine retains the basics of design..
Materials and tolerances are better, designs in pistons etc greatly improved.
Fueling systems far more accurate reducing oil dilution issues.
Fuel cleaner as well...
Filtration quality has generally improved in oil, fuel and air filtration..
35 degrees is nothing... Dusty dirt roads are nothing... Unless you are eating someone else's dust...
While I definitely don't condone it, we had a mine Prado 150 that did 70,000km from new and never serviced (long story - remote site, no service bay for LVs and a Senior Mine guy who was in charge of the vehicle and that couldn't be bothered)..
The oil was saturated with carbon. Some new oil, a flush, some more oil and a couple of filters... and it was back in service. Its now pushing 300,000km and hasn't given a problem since.
That vehicle spent a lot of time idling, running, in temps up to in excess of 45 degrees for 10-12 hours.
It is now serviced by the book (although at the 70k service Toyota voided the drive-line warranty - I consider that justified!)
My vehicle (D4) and wifes (D90) get serviced just shy of the LR quoted distance and I take samples and have them analysed... So far I have no reason to be concerned for the longevity of either vehicle mechanically.
Our vehicles regularly run long runs above 35 degrees, and then in winter have desert temps (negative) to deal with...
Using the UK only as an example - their engines spend a lot more time in enrichment (extra fuel scrubbing bores, diluting oils) and short runs where engine tolerances are loose because they dont get up to temp as quickly.
I would take a hot climate vehicle of equivalent age over a cold climate (snow/ice type climate) with equivalent service records any day of the week.
