Suppose brand bias begets neglect, ..which begets bad experience, ..which begets brand bashing. I'll take all comments with a
block of salt if need be. My 2 cars & both trucks are GM, hardly a reason to bash Ford in
any way, since 'YMMV' is a fact of life, and the quality of either is subjective. I won't disparage anything I can take proper care of and repair as needed, so my 'bash' list remains an empty page.

Now If I dare mention oil:
Oil doesn't wear out. Dino oils' varied-length molecular chains sacrifice the shortest as they combine with contaminants, ending up as sludge or filtered swarf but leaving the better, longer chains more or less intact and o'all perhaps a better lube than when new. If this sounds too rosey to be real there's a reason: Ph! As oils turn acidic galvanic action will eat at the 'less noble' and more reactive metals such as bearing linings (babbit). It's kind of like reverse plating, and it seems 'change' sensors monitor Ph to warn us. (The zinc 'sacrificial anodes' on our boats are to spare the aluminum of our props when immersed ....)
Reclaimed oil may smell funky, but having sacrificed its shorter molecular chains to contamination what's left is the good part. Filter and adjust Ph to get serious stuff. Synthetics are made all long-chain from the start. From that they resist contamination and maintain stable Ph longer. Better is better, tho' we all may be changing more often than need be. Ok, no prob, call it
cheap insurance .... you know, that stuff we pay for not because we expect disaster but because it covers our butts if and when.
Hey, remember the old guy who said he always changed filters but never his oil? Well, he changed 1/2 qt or so every time by topping up afterwards, though I doubt anybody's pulled that one off successfully post-WWII ....
