This is the most recent UOA from my 98 Chevrolet S10 ZR2. I dont put a lot of miles on the truck, and it gets starts only a few times a month at best. It sits outside sometimes, in a garage other times. Schaeffer's 7000 5w-30 Hopefully the thing displays OK.

Silicon looks a tad high. Is it an additive package component? You wouldn't be running a K&N "rock-catcher" by chance would you. All and all wear looks pretty good for a 4.3 V6 and you don't have a coolant leak...YAY!!!

Nope, I actually changed from an AC Delco to an Amsoil EAA though. Consistent Si at least... two different oils, so Im not sure. The intake system is tight, though I open it now and again.
