Torch is right on this one. Think about it, if the Manny has you over a barrel for specific product then they have you over a barrel for pricing too. It was the main reason for the law. Once in awhile the gov gets it sorta right.
Back to the OP - don't know if this makes any difference but when my tractor was delivered the dealer told me that Kubota oil was just Valvoline oil in a different jug with a markup.
No. SUDT-2 is not available in Canada. From the MSDS, the "Premium UDT" sold by Kubota Canada is made for them by Shell Canada. The MSDS shows it is a petroleum based product, albeit a winter grade formulated with a very low pour point. It looks somewhat similar to John Deere Hyguard Low Viscosity but closest of all to a Shell automatic transmission fluid.I also asked for a pail of SUDT-2 but when I got home I noticed the pail said Premium SUDT. Is it the same?
