I'm going to do a fluid change in my ZT-3100s before mowing season. I had planned on Mobil 1 15W-50 for $30/5qt, but I noticed Castrol GTX Classic 20W-50 on clearance for $13/5qt. VR1 20W50 has a stout add pack for about $35/5qt. I just used plain old SuperTech 20W50 last time before I put much thought into it.
Which would you go with? I don't mow terribly much but want this zero turn to last.
A couple recent VOAs on the Mobil and VR1 below. I couldn't find anything on the GTX Classic.
