What kind of gas do you guys burn through your mowers? i have an exmark with a 19 hp kawai on it. 87 octane do or would you reccommend 89? How often do you change the engine oil and what kind wieght do you use? How about Hydro fluid?
The manual says use 89 octane minimum. change the oil every 50 hrs of operation and change oil filter every 100 hrs of operation. The weight I use 10w 30, I am located in florida. Not sure on the Hydro oil. I have belt driven.
