In filling the filter before you install it, you insure that the pickup tube has oil in the system quicker than if you did not fill it. It is MUCH better than not doing it and hearing tapping noises from a dry system after the change.

It's easy on this car, and it minimizes the delay getting oil through the system on the first start.

I'm just programmed over the years to fill the filter. Always was told never start a car with no oil. No oil in the filter, means no oil in the motor.

I've never worried about "priming the filter" on an oil change in any car that I've owned.
I have "primed" new engines on "first start" -- I subscribe to that as a good idea.
My "bias" is to the 3,000 mile oil change frequency regardless of what any manufacturer might say ---- never had an engine lubrication problem in close to 40 years worth of oil changes on a wide variety of vehicles.

I'd ask, why not? It certainly isn't going to hurt and only takes about 15 seconds...

I used to prime and then suddenly the light of this logic hit me about 15years ago. So I don't anymore. Haven't had a problem in the 15 years since I stopped and didn't have a problem in the 20 years before I stopped. So I don't think it makes any difference.

This effect is probably minimal though...
