Cat. I have seen how they perform in earthmoving equipment for 40 years. Best parts network on earth.
I will be honest. The crap that happened to the 3116 has soured me from small 6 cylinder Cats. I am sure the 3126 is a fine engine. The 6LY is an excellent engine as well. I have had nothing but great experiences with Yanmar so that is why I lean that way.
Not intending to hijack this thread but I am curious about what oil you cat 3116 owners use. I understand the straight 30 weight requirement, but some say only cat Saeo and others say rotella t1 is fine.
Rotella 30wt works well in my 3126s.
