Well, I went on a quest for the Mobil1 5w40 Full Synthetic Diesel Oil (thats a mouthful!) and I went to autozone...no go, Napa, no go, Napa referred me, and a guy with a brand new Duramax truck (was there looking for the same oil!

) to a Oil Distributor about 6 miles away, so I went there, and got a Case of it, four 1 gallon bottles for $133!!!!

I figured it'd be "ok" since I am going to run it about 4500-5000miles per change, but whoa! Expensive! Dealership OEM oil filter too, that was $17. SO I am broke now, but am also going outside to do my oil change with this nifty stuff, I want to see if it runs any differently.
