This was my first UOA for my truck... was my dad's, but when he retired it just sat in his driveway for about three years (maybe 10,000mi total over that time period)... so I took it off his hands last year, bulletproofed the heck out of it (to the tune of about $5,500), and figured now a year later I'd get my first UOA. EGR is deleted, new oil cooler, new ARP head studs, various oil fittings, turbo-back 4" exhaust (cat free), rebuilt & upgraded FICM, etc etc etc. Truck is tuned... mainly running Gearhead's SRL+ for daily driving, but dialed back to his 8k Tow tune when appropriate. Truck is used for a daily driver to my work about 7mi each way... it does get up to temp along the way. I take it on the highway at least once a week to "run it through". I re-filled with the same oil and have one more OCI stashed in my garage (got it during AutoZone's $12.99/gal sale they had earlier this year). After my stash runs out I am going to give one of the 10w30's a run considering how mine got shredded down to a 30-weight anyway... and seeing RoadRunner's 10w30 UOA makes me more curious. =) Any questions, please let me know! LOVE this truck. 5,000mi UOA run... 65,000mi on the truck total Oil filter = OEM Motorcraft / Racor Fuel filter = OEM Motorcraft / Racor Air filter = OEM Motorcraft (I did change the filter mid-OCI) Fuel type = Mainly b5 w/ 10oz Diesel Kleen per 25gal... however last two fills were with commercial b20 w/o Diesel Kleen.
