I recently picked up a IH 5088 2wd from a neighbor. Tractor was setting for several years until he got motivated to sell. In the last couple of months he changed the tansmisison oil and filters erplacing the oil with Tractor Supply Transdraulic fluid. I have read several postings in the Red Tractor forums regarding oil for IH tractors and everyone says to use only Hytran in IH tractors. This tractor takes 43 gallons and manual recommends adding another 5 if working on slopes, or after changing the suction filter as there is a spot that might suck air.. The Case/IH dealer has Hytran for $115/5gal bucket. That works out to $1150 for an oil change. I don't expect to use this tractor under a full load at all and I don't believe I will be shifting up and down to use the Torque Amplifier much. It will be used on a 15ft Bat Wing mower and a 1500 gallon sprayer. I have used Mystic oils exclusively for 50 years, until Mystic's latest price increase. I have laid in a supply of Rotella T4 until things calm down with Diesel oils. I am sure there is a slight price break if i get the Hytran in a 55 gal drum, but having to take out a short term loan to change oil in a tractor is ridiculous. I would appreciate any halp here if there is a less pricy equivalent.
