Oil change time on the Farmall 806 Diesel. That tractor is used to pump thousands of gallons of water for our race track prep. I used some @Lucas Oil synthetic universal hydraulic & transmission oil, I also changed both oil filters with some much needed new SAE 15W-40 Lucas Oil engine oil, and to finish with changed both fuel filters. Can you guess the year of this International tractor? #oilchange #tractor #lucasoil #lucasalliance #maintenance
