I'll be happy to use 0W-20 year-round as its the same price at my local Canadian Tire for Pennzoil Ultra Platinum. Is 5W20 just a relic of the past then?
I checked some of the threads but none are conclusive on the topics. Closest was one person arguing the reverse.
All year round? Wow. There are no disadvantages to running 0W-20 then? I fear the warmer weather of the summer would be counterintuitive, no? I see multiple threads on this forum...
Hiya gents,
I have a 2012 Mustang with the 3.7L that is specced for using 5w20 with Ford WSS-M2C945-A.
I live in Canada and its getting quite cold here. I know that the 5w20 is certified for down to -30C/-22F, but already at -20C/-4F I am seeing much more laboured cranking and even brief oil...
