I work for a railroad and we have thousands of fleet vehicles on the road every day. Basically, their oil gets changed at approx 5k mi with whatever type of oil that shop uses (Midas, Jiffy, Stealerships). How many of our vehicles ever fail due to oil related problems? Not many, and many sit and...

I use this one from Menards on our well water. It does great with the included carbon wrapped filter: https://www.menards.com/main/plumbing/wa...154&ipos=30 I get about 6 months between changes but the filters look rusty real quick!

Let me call my service advisor to find out But seriously, I'll check when I get home.

Well update 18....service advisor told me it was 5w-30 but after he searched the records, it was indeed 0w-20! Thanks guys.

Just got 6 quarts of M1 5w-20 for the Grand Cherokee on Amazon prime for $27! Not shabby.

My GM dealer used 5w-30 in mine and since GM has their own full synthetic as of the beginning of this year I opted to try it out (hard to beat at $60 for an 8 quart oil change plus tire rotation!) I got my Blackstone oil analysis back (after 5,000mi) on the Ecotec3 6.2 L. Posted last night...

I forgot to mention that I have a Tracy Lewis catch can installed on my truck as well. Perhaps that is keeping some moisture and contaminants out of the oil.

Yes this is the 5w-30 GM used in my Ecotec3 6.2L.

I wanted to see how GM's new AcDelco 5w-30 Full Synthetic is doing in my 6.2L. My service advisor said they are pretty sure it is made by Mobil 1 but who knows. Hey, I'm pretty happy with the analysis after 5,000mi especially when I can get an 8qt oil/filter change get & tire rotation for $60...
