Age old question ........ "what can I get CHEAPER than what Kubota puts in ? "
Well - several people using HST's HAVE used other oils............ and some had terrible results and some had good results........ some keep saving a few bucks and some have gotten their asses twisted in repairs.
the question really boils down to this ............ $100 now ....... or $52 (I am making this number up) ....... and by saving $48 bucks ........... I may need a $7,000 new HST unit down the road?
I went to the Kubota dealer the other day ........... $24 a gallon for the good stuff S-UDT2
Not sure what cheap stuff really goes for !
And as someone said on another post here today ............. why NOT just put in what Kubota used from the factory....... AND I agree with that ........... But remember this - Kubota does NOT make oils ..... they buy them from an OIL manufacturer. Pennzoil I understand.
YOU cannot go to the store and by Pennzoil HYDRAULIC oil that goes in a Kubota HST - But you can buy oils that SAY THEY MEET THE SPECS of Kubota's oil............ good luck with that! I have some crisco that I can write on the back of the container that says it meet certain specs.
ENGINE oil is a completely different set of specs. A diesel oil is made for DIESEL engines ...... other than a DPF and turbos - all diesels engines are pretty much the same - you need an oil that will keep on working as the particulates dirty up the engine oil - and Kubota's engine oil is simply a re labeled diesel engine oil.
Rotella - Mobil 1 - Valvoline - Pennzoil all make great engine oils ...... pick one of them and go with it !!!!
A gallon of Kubota engine oil ......... $22 for 10w-30 ............ Rotella T-6 $22 for 5w-40 ...... and that is full synthetic too!!!!
Buy whatever you wish ....... your money , your machine !
