Is safe to use 15W50 full synthetic in place of the SAE20W50 conventional oil in the Hydo Gear transaxles? Hydro Gear sales don't the answer and wasn't willing to find out.
BTW I just told Walmart go F themselves since they refuse to accept my sale tax exemption certificate. I even turn in my local card. Why buy from someone that refuses to accept my paperwork provide by the State of Tennessee. I just order 5 gallons of 15W50 full synthetic online at the same price as the Walmart's Mobile One out of Salem NH.
