Why is your 91 Buick Skylark blowing out cold air even when driven for 30 miles?

Thermostat stuck open or heater core plugged. CONSIDER THE POSSIBILITY YOUR HEATER VALVE IS CLOSED/CABLE RENDERED INOPERATIVE BY A BROKEN PLASTIC SLIDER HOUSING,AS IS OFTEN THE CASE ON OTHER MODELS/MAKES,SHOULD IT NEVER WARM UP.

I think it's once every two years or 15,000 miles.

Trade it in for a Vette or something... You dont. And the 89' skylark gets WAY more than 7 miles to the gallon. I get about 20-23 in the city and 32 on the highway.

Probably around 16 mpg. I had a 1969 LeSabre once and the best I got out of it was 18.6 on the freeway.

Depends entirely on how it has been driven and serviced. With careful driving and frequent oil and trans fluid changes, I would not be surprised to see 250,000 miles.
