If you wanna use 15w40 dino in a small passenger engine at 0*F/-20*C, go ahead. Make sure you don't drive off right way, and watch those seals.
To quote a mechanic friend of mine:
"And I really wish people would stop bringing their diesel pickup/tractor/tugboat/roadgrader/genset/submarine/locomotive comparisons to these threads."
LOL - that was funny
Yeah But Taxi and mixed fleet vehicle examples were also quoted. There are no Taxis running diesel in Australia, only Petrol or LP Gas.
At 0 to -20 would you drive off straight away with a 0w20 oil in it ? I dont think so. There are 25w60 oils that will still flow adequately during warm up at -20^c.
Yes, normal procedure (per the manual and also what myself and many people do) is to start up, wait for the idle to smooth out (at most 10 seconds), then drive off. This is with 0w30, 5w30, 0w40, 5w40. This applies to diesel and petrol engines.
-20C to 0C is not really cold, just normal average winter temps, many places see colder.
