we got the truck used; a hand me down from her mother with 100k
the last 50k were pennz so i ran pp in it because it advertised to be very clean and i figured it would be less likely to gunk up because its the same maker.
pennz has had a bad rep all my life and the engines i have been in that the owner swore by pennz or QS were very ugly to say the least. maybe its because they were wore out pos or maybe the oil is diff now idk
one thing i do know is everytime i change the oil on her truck it is black as night at 3k
and every time i change the oil on mine it is cleaner but mine has varnish build up from what i can see in the oil hole
idk what the previous owner used or the oci was i got it with 125k on the meter
needless to say i will be runnin a few ocis with PYB and MMO in my truck and then switching it to PP!!
im not saying the engine was dirty and 3 ocis with PP made it sparkle(thats far fetched) what i am saying is i KNOW FOR A FACT pennz products and 3k ocis will give you a clean engine at 110k. no guess work, no claims, i saw it in that engine.
it seems to be if your used oil is dark but not gritty and still smooth feeling the oil is doing its job dissolving and holding the contaminates. just a theory
