I doubt that 0w20 would make a difference (over 5w20) in Florida.
I plan on using 0w20 in my Elantra this winter when my daughter takes it up to college near Rochester NY....I figure she will do a lot of short trips and the weather is cold up there...
While I think that both are excellent oils, I would go with M1 if I had to choose....
An earlier poster asked about Synpower and Napa Syn. 0w20...does anybody have an opinion on these in comparison to M1 and PP??...I picked up a case of Napa Syn. 0w20 @ $3.49 a quart last month...it seemed like a great deal...
