JMO.
I detest the water recommended in our gas engines, but I use what is recommended.
Don't have gauges in these vehicles, as long as the idiot light doesn't come on I'll continue. Or if consumption picks up.
Again MO.
Folks try too hard to make a big deal of oils today.
Lotta gum flapping about early changes, premium oils...
Stuff posts the specs it meets, it's not rocket science to match requirements to specs.
I've seen a Duramax with 50 or 80k(foggy memory) on it with the original oil.
A snack food delivery truck, the original operator never had it changed, it's new operator brought it in. The oil was like glumpy STP. It took forever to get it out of the pan. Our guys dumped a couple gallons of diesel in it and left it sit, then drained it again. Changed the oil a few times over the next month, and it cleaned up.
The engine never showed any stress, before or after.
Was it harmed?
I'd bet there would never be any way to know.
Some engines from that batch will fail early, for a bunch of reasons, some on schedule and some will be abused and last longer than expected.
I certainly wouldn't recommend this, it was absolutely abuse.
One thing that's not opinion.
Most American folks buying new cars and spending extra on oil are wasting
their money. Good maintenance and special oils, if they payoff, payoff at end of life.
The buyers of new cars usually don't have them until end of life.
They trade by 100k.
Top tier synthetic, or Walmart oil that meets spec, will get you there with a
health engine to trade in today. Or there were issues outside of the oil.
