Thanks for video, I have hydro gear zt-4400 transmission book reads "Fill the transaxle with new 20W50 motor oil
through the expansion tank" port / fill port. " Should it be regular motor oil or hydraulic oil?

We recommend buying Scag 20w50 hydraulic oil from your local Scag dealer. The part number for a quart is 486255 and for a gallon is 486254.
Your owner's manual (if your machine is a little older) may say to use 20w50 motor oil. That can also be used too. However we recommend Scag branded hydro filters and lubricants at least while the unit is under warranty. Thanks for your question!

I have a Yamaha golf cart which suggests using conventional engine oil due to the splash lubrication system. Will synthetic small engine oil work just as well or not.

Thanks for your question! First, we should say that we do not distribute or sell Yamaha Golf Carts. Really, your best bet is your place of purchase for this question.
That being said, our tech team passed along that synthetic oil should be fine as long as you keep it the same weight.
