Well respected in industrial applications especially where unusual cold temps are experienced ... basically northern areas of a province in Western Canada, Yukon, NWT, Nunavit. Also well respected in agriculture, mining, forestry, road building equipment.
I've worked in Northern Saskatchewan where January and February morning temperatures range down to -45C (-52F) and occasionally lower. Yes, we work in those temps outside. Steel parts snap like plastic, plastic explodes like glass. When you do a repair, it's important the lube allows you to startup again four hours later.
Where some places a shutdown causes loss of money and time, up north you have situations where if a critical machine shuts down for 20 minutes, or you can't start the backup generator to keep the heat tape inside you water lines going, you may as well go home till spring. And no, we've never had to go home till spring, with the sound of toilets exploding behind you as you drive away.
Light-Duty Diesel vehicles are simply never shut down, idling away while the driver sleeps, but you can't do that with a gas motor and expect it to live past 60,000 miles, so it has to be able to start.
Quality does not seem to be an issue; just make sure the application is appropriate.
