Fuel dilution - 1.9 mile commute. Let idle before leaving?

Change the oil more often, problem solved.

Not really, the wear on the motor is greatly increase running it only cold...he has an EV he could drive instead...boggles my mind!

It’s a machine meant to serve.

The Miata is a fun high performing car

As a fellow MX-5 owner, I determined this is a lie

I quite enjoyed driving my slow Miata as a commuter before I ultimately built it up to be a monster weekend warrior and track toy. People can drive what they want, when they want, how they want.

Even if that is true, have you ever seen an engine "wear out" within the first 200k?

I have an NB2 Miata. My commute is 2 miles each way.. My oil reports (blackstone) are coming back with somewhat high (correction, low, 375f and 420f on two samples) flashpoints. I understand that there is debate about the reliability of blackstone's flashpoint for fuel dilution, but my question is more, what is best practice for starting the car in the morning? Typically with any car I let it idle 30-45 seconds, drive easy until oil is warm (about 5 minutes after coolant is up to temp).

But, with such a short commute, there is no way my oil is getting to temp. Should I let it idle longer in the mornings? Take a longer route to work?

Your vehicle was designed to start up and Go.

In my case (Hyundai Kona N-Line 1.6 GTDI), my kid's school is a 5 km return trip when school is in session. I'm acutely aware of fuel dilution under these circumstances. Although a waste of time (and gas), I do drive an extra 10 km (15 km total) after drop off to at least get the engine to operating temps. Not foolproof, but I think it's a reason why my last oil analysis came back with no fuel dilution whatsoever.

Yes, many motors have worn out before 200k miles, for bad maintenance.
