Roger...Confirmed! HPOP oil change neccesary

[drumdawg]

If anyone is still thinkin it's silly to change the HPOP oil when the crankcase oil is changed......saw it with my own two eyes. Bought a '97 with a 70,000mi motor and decided to examine the oil in the HPOP. I mean it's right there, just a couple little hex turns away. First I put some oil off my dipstick on a clean paper towel, then sucked out approx 20oz from the HPOP. The crank oil was gold with 2,000mi of soot in it, kinda dark lookin' when a bunch is stuck to the dipstick. Looked decent on the papertowel. The stuff from the HPOP on the papertowel was at least 3 shades darker...... All I can say is I absolutely do not want to run my injectors on that night black 'oil' left in the HPOP and will always change it with the main oil.

....wait is that someone kickin back about how its the same oil recirc from the main crank. That didn't take long.

Drain, drain away Just know that no matter how much you pull out, you will NOT Be getting the oil out of the oil rails or the injectors. So as hard as you try, you are still circulating old, used oil. This has been on here many times and you'll get a bunch of different opinions, mine being leave it alone, it's not hurting anything.

The oil will just be pumped out as soon as you fire the truck anyways. You'd have to do a full rebuild and wash to get all the oil out, the amount of old oil remaining from a regular change is quite small.
