Since the last 5 fill ups with Shell 87 fuel, I have used so far
1 can of Seafoam in the fuel
2 Penzoil Injector cleaner
1 Penzoil Fuel system ....
Will these adatives cause a problem with the oil analysis?
So far the engine has received 2 stage treament of Auto-RX w/ Castrol GTX 10w40.
Now it's on its first AMO Amsoil 10W40 synthetic oil change
