Newer VW's (last 20 years), it doesn't really matter. Cheaper, low octane gas can cause knocking (early detonation), but the knock sensor will retard the car's ignition timing preventing knocking, but this will cause slightly poorer gas mileage. Thing is, the extra cost of the poor gas mileage isn't more expensive than the cost of higher octane gas, so it's pretty much a wash.
Older VW's without knock sensors can have poorer gas mileage with cheap gasoline. This knocking will happen under hard acceleration. The knocking will be worse with higher compression (over 1: 8.5) engines like in the GTi, Cabriolet and Scirocco.

No, most were liquid cooled. The (original) Beetle and possibly the Type 2 (not sure on the latter) were the air-cooled Volkswagens.
