It's been a while since I sampled oil in wife's truck. I have no complaints with this truck it's been a great vehicle.

Did you change air filters before the last sample?

Older formula. I put 3 quarts of the older in when I changed it.

No I did not, it has been an Amsoil one since second UOA 62,000 miles. Installed Amsoil air filter and silicon went up. I don't remember the things I tried to get silicon down but it appears that not cleaning it works pretty well. I can't remember the last time I pulled and cleaned it
