Thanks for your persistence.  Lets hold off for two

Diagnosis: a damned air filter. Mileage climbed from low 25's to 28

Absolutely stupid. Sorry for all the "storm". When I actually did
oil changes myself, I'd replace the stupid thing every other oil
change. But if it is not a schedule published by GM, it does not get
done. Depending on the dealer.
