What oil filter are you regularly using?

I just happened to be doing some reading on ISO 4548-12 which is a standardized test for oil filters. I haven’t found a recent chart depicting the results. But I’m still curious what’s your go-to for filters?

I’ve been using the Wix brand for a while, but then it got pricey, so I’ve been bouncing between brands. I used to buy OEM by the case but then those got expensive too. I have some Fram Extra Guard filters right now. I still change the oil (full synthetic) every 3000 mi though and I think it’s a good idea considering the age of the engines (oil burn off). Perhaps it doesn’t matter as much but still curious what you guys and gals are running.

I used to buy OEM by the case. In recent years, if I didn’t plan correctly and don’t have one on the shelf I use Mobil 1, if I have time then Amsoil.

I try to change it after each track day. The last 2 were kind of close and I ran out of time. I will send to sample to Blackstone labs and see how the oil is.

Where are you guys buying OEM? I heard eBay and Amazon were flooded with fakes.

Looks like the part number changed again: 15400-PT7-005 (Allied Signal USA)

Apparently the Honeywell A02 Part that was running for a while was crap. I think that’s what ended up making me switch from OEM a few years ago and I forgot about it.

Local Acura dealership.

Befriended a technician or two near me and was able to buy OEM through them from their work.
