[David in San Antonio]

I always turn off the fuel about three blocks from home. There is just enough fuel left to pause in the driveway, open the garage door, and pull in. The engine idles for about 30 seconds before quitting. If I don’t run it dry the garage smells strongly of fuel.
I also use Valvoline VR1 20W-50 Racing Motor Oil. You can go down a deep rabbit hole researching oils. “The Motor Oil Geek” is a scientist on YouTube. He has a good explanation of why you should never use an oil additive.
The discussion about oil filter system add-on (full flow vs partial flow) is also a deep rabbit hole. I even had an engine builder refuse to add an oil filter system to my engine because he’d “seen engines blow up” because of it!
