With the oils to the 1950s engines were very prone to cold running bore and ring wear. Wear virtually ceases at full temp. Many old studies showed wear in 1st few miles exceeded a hundred or more following. Not so critical with modern oils (maybe not classic). Neverthelss modern cars with near no wear despite enormous working pressures go to great lengths to acheive fast warm up and hot operation. With Sevens condensation is esp undesirable as corrdes the roller bearings.
Starts just to move the car a few feet should be avoided. The fan belt can be removed and the radiator blanked for short stationary runs.
i suspect a thermostat would have more influence on cyl wear than all the exotic modern oils now often passed through the cars.
