Fords were most notorious for non-wipers when under load, but the 1950s series Vauxhall Velox and Wyvern even had a knob on the dash for adjusting wiper speed, of course it made no difference. This posed problems for the police who used the Velox and found the wipers stopped when they opened up to chase the baddies.
Regarding oil consumption, and returning to our aviation theme, may I recommend OMD-370 as used in the Bristol Hercules? Being as thick as tar it greatly reduces oil consumption while muffling the bearing rattles as well. This quite extensive roadgoing use may have caused an apparent increase in Hastings oil consumption, though maybe I should not say this lest the Historic Allegations Squad breaks in the door.
