Here is the first used oil analysis I've performed on my Fiesta. I've had her since Christmas last year and have changed the oil twice before but this time my curiosity got the best of me so I sprung for a used oil analysis. I bought it with 23k on the clock and she now has almost 44k. Most of my driving is highway driving so I think this is partially why the report came back with such low numbers. I think I am going to stick with Pennzoil Platinum 5w20 and/or 0W20, use up my stash of K&N filters that are made in the USA and then switch to WIX or Napa Platinum filters since they're on sale by me quite often. I'm seeing 12K+ OCI's in the future with this combo. What are your thoughts guys?
