hey all! it seems like 0w has become the gold standard now a days but ive read and heard some conflicting info,
one side of the story says to get a 0w as it will flow faster at startup, however a diff story says that at hot ambient temps (meaning cold startup at the lowest of outside temp of 60f), 0w and 10w startup flow would be the same and that the 0w would only be better at temps colder then example 32f etc etc
ive seen some conflicting graphs for both so not sure what the correct info is
the reason i ask, is im at a hot temp so if hot ambient temp cold startup flow is the same or very close between 0w 5w 10w then its a no brainer to get a 10w since it will have less vii etc and less shear etc, however if the cold flow even at hot temps (60f) is better with the 0w then i guess better to go with the 0w since the shear probability is probably low
i was also hoping that maybe a 10w would have a larger film strength / 'stickiness' compared to a 0w which would mean the oil would stick to the parts more vs all draining to the pan as a 0w would but maybe that is just assumption
i know i am def overthinking but this is what the forum is for ahha! so looking to make a choice on the miniscule difference
