07F150Lariat5.4

Hello, everyone. Did a 2nd oil analysis on my '07 F-150. I posted the last one here about a year ago. Wanted to leave it here for you guys. This interval was 2,815 miles on Motorcraft Synthetic Blend 5W-20. I keep the oil intervals on this truck really short because it gets driven such short trips and a ton of cold starts between intervals.

One thing I noticed was my iron went down, but aluminum went up 1. That's really not anything to be concerned about, is it? The lab didn't seem to consider it a problem. I overstress over things like this, but just want other opinions. Thanks!

I also use Blackstone but I go around 8k miles on oil changes per their recommendation. I use Pennzoil Platinum 5-30 synthetic.
Last change I went just under 10k miles but forgot to grab a sample to send in.

Thanks for the reply! I would go longer myself, but the truck gets driven only 10 miles here and there. Lots of stop and go city driving, etc. Still haven't had to do any timing work luckily! I wish there was a thread specifically for UOA posts. Would be cool to see everyone's analysis results.

Just post it on Bobistheoilguy.com if you want comments.

As for the anaylsis, your fuel dilution is fine and viscosity and cSt are fine. You could easily do 5000 mile/annual oil changes with what you are doing.
I would not worry about the small change in Al and Fe. You are going to have differences in each UOA. So long as your not seeing a trending increase in Al (like next time it is 5 and you start seeing Copper, Tin and other metals rising) you are fine.

Thanks for your reply! I do have a tendency to worry about things that don't even need a second thought. I'll send in another next oil change probably and see what happens then.
