GL 1 tranny oil

[Ron Pilger]

I looked, make that searched, for a couple of years across western Canada to try non GL-5 gear oil. A few young parts managers didn't know there was a rating. Got the standard answer - "GL-5 will be just fine". This advice was consistent from plenty of service managers, newly trained technicians and even head offices/research departments of oil companies. Not convinced, i kept my eyes open and ultimately cleaned out a farm dealership which sells the line of Troy-Built rototillers.
