I was at our local WM the other day and noticed a difference in the bottles on the shelves. I'm sure it's been posted before so if someone has a link to a previous thread it would be much appreciated. Anyway 5w20 listed as full syn and 5w30 as a blend. Just curious as to why the difference in listing with the different weights. Looking at using the 5w20 in our 2011 Honda Pilot. TIA!

Mite be due to 5w-20 being a much harder viscosity to produce, From what I have read.
I think the 10w30 and 5w30 semi syn hold viscosity better w a blend. Gonna run 5w30 in my lexusrx350 with a 1/3 qt castrol edge 5w30 as it takes 6,3qts
