Oil capacity on most 4020 diesels increased from 8 to 12 quarts starting with the 1969 model year, tractor serial number 201,000. High-crop diesel tractors retained the 8-quart capacity throughout the production run. Tractors fitted with after-market turbochargers, and early tractors with replacement oil pans, may also have the higher oil capacity.
