The important thing in my choice of a 180 over a 160 is that it helps my motor reach critical
oil operating temp a teeny bit FASTER, on a cold start. This means less wear and quicker "get your motor running" factor.
Chopper, my 4 x 4 Scout II HAS a tractor motor.. (258 AMC/Jeep/originally a tractor motor design) so the study is relevant
