My second UOA on the Focus. This was with a Pure One filter. I replaced the oil with PP 5W20 and a K&N filter (from March's AAP deal). I plan to run that to 8k OCI as well so to have a direct comparison. If PP's TBN is higher after 8k, I suspect I'd run SynBlend to 8k and synthetic to 10k for the life of the car.
Silicone may still be high because I changed the MC air filter a few months ago?
So what do you think, should I have stretched this oil to Ford's 10k OCI recommendation?
Code:
If silicon improves by just 6 ppm every time, it'll take a while to get silicon down to
average, but hey, as long as it's going the right direction we can't complain too much.
Other metals are pretty steady. Aluminum and iron each went up by a few ppm, but neither
increase was so large that we think a problem is at hand. The longer oil run might account
for at least some of the increases. The TBN is a little lower, though that's no surprise on
a longer run. It should drop more slowly from here on out, but it's still good at 1.9.
Overall, not bad at all.
