I’ve got HPS in my 21, HPL in my 18 and while I was looking for torco for my wife’s 24 I found 5qts of maxlife synthetic. I thought I used it all, apparently not! I did end up using Schaeffers since I couldn’t find the torco until after I had changed it. We’re building a separate pole barn to replace a shed, so everything is jammed somewhere it doesn’t belong right now. The maxlife is sn plus so perfect for my 2018.
