JWLubeQuiz Tractors6112018

And the Winners Are…

JobbersWorld ran a LubeQuiz two weeks ago about two old tractors we recently had the pleasure of seeing in action at a working farm. About these tractors, we asked JobbersWorld readers, how do you check the oil in the tractor shown at the right, and what type of oil is used in that tractor and the one at the below it that is cranked to start?

We received a number of interesting responses. Some right, some not so right, and some that were quite humorous. The winners of the quiz, the ones who got it right are shown below:

Name Company
Erik Dober Jerry Willkomm, Inc./ JWI Transportation
Frank Daul Halron Lubricants
Curtis Grove
Tim Svoboda PetroChoice
Brad VandeBunte J & H Oil Co.
Wayne Hughes TOTAL Specialties USA
Terence Dyson DysonAnalysis

Whereas all the winners said the two petcocks on the oil pan are used to check the oil level, one answer in particular sounded like it came right from the farmer’s mouth that we visited. This answer was from Tim Svoboda with PetroChoice. Tim said, “The tractor has two petcocks to check oil. It is always best to check oil after the tractor idled for a few minutes. The upper petcock would drain until it dribbled, close it, then the tractor has enough oil in it. When adding 30W to this age of tractor, most farmers had to use a glass-quart-Mason jar with a screw on metal funnel.”


With regards to both how to check the oil and the viscosity grade used, Erik Dober from Jerry Willkomm/JWI Transportation summed it up by saying, “Check oil level on the side of the oil pan. Two petcocks on side, lower is your low oil level, upper is full. Oil used should be: Above 80°F use SAE 30, 32°F to 80°F use SAE 20, and below 32°F use an SAE 10.”

For those unfamiliar with this tractor, it’s an International Harvester Farmall Tractor. Other than saying it was from the “40s,” the farmer did not know the age, but he sure knows how to keep this one and all the other tractors on the farm running.

Congratulations to the winners!
