Too Hot

Power vs longevity.
We used to valve grind @ 60 - 80k mi.
Re-ring ~100 - 120k mi.
Leaded gas, ~180* thermostat.

Now we often get 200k with oil changes only.
Unleaded fuel, ~ 200* thermostat.

No question motor oil and metallurgy has come a long way .

EFI is most of the longevity mostly because most people were tuning their stuff like they change oil.

Not often enough.

As for wear if you use a good oil and tune up your induction wear is no different.

If you aren’t doing it you don’t know.

So I guess the question is have you seen this wear?
