In 1946 my dad bought his first new tractor, a grey Ford. We had a
Pure oil distributor and dad bought it by the barrel 20w20. It figured
out to be at that time 9 cents a qt. The distributor was in business
for about 8 years and Texaco was the distributor. He did buy some Havoline
20w20,then went to Tydol,then Gulf Pride HD Select 20w20.
Never ever had a oil problem, the trouble was always air problem.
