I was going to suggest changing out the filter but too late for that. I see this a lot where someone purchases a used vehicle with unknown service history especially when going to a synthetic oil that it cleans a lot of the crud out of there and it all has to end up somewhere and luckily for you it was the oil filter and caught it in time before it could really do any damage.
Typically when I purchase a used vehicle and don't know the history I'll check the oil to see if it's been changed recently or not but when I do change it I mostly use Chevron Delo xle 10w30 which is a great oil and cheap too but if needs 0w20 or 5w20 then I'd use a good quality synthetic blend and monitor the oil consumption and change it out between 3k-5k miles. I'm usually not picky about filters but do tend to stay away from those orange cans but will use their other ones but I usually go with the oem filters such as AC Delco, Motorcraft, & Honda but also use Napa/Wix & Purolator.
Yeah. I checked the oil when I bought it but it was fresh. Bought it from a dealership; and they had changed the oil as part of their “pre sale service”. (I’m reasonably sure that’s the only thing they did, it was due for a lot of other stuff which I took care of when I got it home. Trans fluid, diffs, transfer case, brake fluid, etc.)
If I’m not mistaken, these had synthetic from the factory. If it was serviced at a dealer, it would’ve been serviced with an ACDelco branded synthetic. According to my brother in law who is a GM dealership tech.
AMSOIL said that they see this and it’s usually carbon, not sludge, that clogs up the filter. These engines just apparently produce a lot, according to them.
