0w-20 or 5w-20 oil?

[VOLTundra]

Okay I know are numerous threads on oil changes, but I have not found this answer. I thought I saw a post somewhere some time ago about someone buying the 0w-20 at Wal-Mart for around $20 for a 5 quart jug. Does anybody know the sku? My Wal-Mart does not carry the 0w-20 except by the quart and it is $2 more than by the jug. We won't mention that the first one only carried 7 quarts. They only have 12 max in stock.

My other main question, have any of you found the 0w-20 Advanced Fuel Economy worth the extra money? Do you find it to really increase your mpg? I did notice the second Wal-Mart carry the 5w-20 Full Syn. in the 5 quart jugs for $20, so this would be about $15 savings per change.

Any Suggestions are helpful.

Either is fine in your truck.

0W20 will not increase your mpg vs 5W20. They are both 20 at normal operating temp. The 0W will flow a little quicker than 5W to engine parts when the engine is started at less than normal operating temp.
