I was too lazy to change out the 180 thermostat for the stock 195 this past winter so I decided to try a 5-20. This oil saw cold temps(-5F to +10F mornings)and sat a lot due to high gas prices,I used a Sentra for commuting.Oil was in service from January 12th to May 7th of 2007.It also saw a bottle of RL S1 fuel system cleaner and an intake manifold spray cleaning. Air filter was changed near end of interval with same Wix paper #46077,17,418 miles on old air filter. Baldwin B2-HPG over sized oil filter,1 quart,giving me a total sump cap of 6.5 quarts.1/2 quart make up oil added.PP 10-30 went back in with Amsoil EAO42 stock sized(.5 quart)oil filter. Also replaced 180 stat with stock 195.Used Blackstone Labs this time.

First column Amsoil ATM 10-30 9987 miles(17874 total), Second S2k 0-30 6122 miles(23996 total), third column S2K 0-30 8758 miles(51184 total),fourth column GC 0-30 10,323 miles(61507 total).Fifth column PP 5-20,Blackstone Labs, 4,647 miles(86,822 total).

Not bad at all for the wrong application. Meaning not recommended by Dodge.

I agree! I just figured that at a lower temp stat the 5-20 would be like the 10-30 I have in there now with the 195 stat. During winter it STAYS at 180.Even with the 180 stat in summer it still creeps up to 210,especially when I tow uphill, then the 5-20 would really give Dodge a headache!

Thank you for sharing this. I'm planning to move to Fairbanks Alaska next month and have been thinking about using Amsoil 0W-20 for the extreme winter months in my 04 Dakota with the 4.7 eng.
They specify 5W-30 for this engine for 04 but for the last couple of years they specify 5W-20 for the same engine.
I called Dodge to see if they back-spec'd the 5W-20 and they couldn't come up with an answer so finally just said "go by your owners manual". I would follow this advice and be done with it but with temparatures dipping below -40 and not being able to plug in the truck everytime I shut it down, it could prove to be very advantatious to be able to use the Amsoil 0W-20.
It appears from your single run of PP 0W-20 that it might be a better bet for a Fairbanks winter.

Thanks Again!
