I guess having such a tiny little engine engine probably makes it pretty easy to start even with molasses in the crankcase.Well, just for fun I checked out the Temperature and Viscosity chart in the owner's manual of my late great 1979 Mazda GLC.
It shows 20W-50 being good down to -10°C (14°F), and good up to 50°C (122°F).
You do know the temp range this covers correct? And what the " W " denotes in "20W50" ?I guess having such a tiny little engine engine probably makes it pretty easy to start even with molasses in the crankcase.
I appreciate the conversion effort but it's a little off. 5W20 is only acceptable to 78*F? Man, my F150 is screwed.Here's viscosity chart I converted from °C to °F

76 Seville I had said 20 F. In manual.You do know the temp range this covers correct? And what the " W " denotes in "20W50" ?
I don't remember, but I had the original for quite some time which showed °C and about 2-3 months ago I cut out the °C and replaced it with °F using Google Sheet and took screenshot of it with IrfanView. I also thought that the upper range for 0W-20 and 5W-20 was kind of low.I appreciate the conversion effort but it's a little off. 5W20 is only acceptable to 78*F? Man, my F150 is screwed.
Where did you get the original chart?
That car started amazingly in the cold. One night I had to do a cold start at -38 C to help out a friend. I had not planned on driving the car, and it wasn't plugged in. It started fine - the secret was the manual choke.I guess having such a tiny little engine engine probably makes it pretty easy to start even with molasses in the crankcase.
