longest oci with a pure one

In most cases when the oil is hot, the added restriction still may not make any difference unless the oil pump is in pressure relief most of the time.

Under the same operating conditions (oil temp, engine RPM), the only time the engine's oil pressure will drop (what you see on the oil pressure gauge) is when the oil pump is in pressure relief mode, and there is more restriction in the filter due to A) a more restrictive filter design and/or B) use of a higher oil viscosity.

Whenever the oil pump is not in pressure relief mode, all the oil coming out of the pump is forced through the filter/engine oiling circuit. The only exception to this is if the oil pump is so worn out that it has massive internal leakage and can't force the same volume through a more restrictive path.


Good stuff. That actually makes perfect sense.

I'd say for non-sludge state engines, a P1 is capable of hitting 10k without filtering to capacity. I may not use a very fine filtration filter when using a high detergent oil, though, like a High Mileage...if I'm leaving it in for more than 7k. You may filter to capacity too fast. IMO, if you are using a HM oil, you should really keep it to 5k or less to make use of the oil for it's intended purpose and get the gunk out that it 'cleaned'.


im not so sure a hm oil has more detergents. at least nothing has stood out on the uoas that i have seen. as far as cleaning goes id put PU and PP at the top, but thats my opinion...
before i run an extended oci i will make sure the engine is as clean as the day it was built! hence the PU and kreen

That's pretty funny, actually.

Hmm, well that's what I thought was the case. Maybe that's just their marketing gimmick? I agree on long OCI, anyway.

About 9K on a 92 Honda.
I cut it open and found absolutely nothing out of the ordinary. The filter media was structurally sound and showed no signs of being clogged. (Needless to say I didn't perform any formal flow tests, etc.)

Oh, oh!!! Have you ever used the Wix 51334(or Napa Gold 1334)?

I'm considering using the Pure1 for my 92 Civic, but haven't yet.

I'm thinking you probably had a leaky ADBV on the PureOne.

OK, but 4+ separate leaky ADBVs?

Where did he say it's happened to him 4+ times?

Why not? I use them on an 01 Civic with ~150k on the clock. Also, a 3.0L Accord, last time 1 year Honda max, 7200 miles. Never had any issues, great bang for the buck filter, imo. Here's some filter pics from the last 3.0L 1 year OCI.

Well, it's because I've been using NG/Wix 1334 which is a bigger filter and comparable product. I believe I can get the PureONE cheaper, though, but I like long OCI and I'm still cleaning up the engine from a previous owner. If it were clean already I'd got for it, though I'm sure it could probably still make it the distance. Just a psychological roadblock really.

My goal is eventually 10k+ mile intervals. This is my first OCI using Amsoil SSO, after first getting the car and catching it up on all of it's mechanical issues(a good $2000+) over the course of the last year, this is after we put MaxLife in it for 3 OCs, with 1 or 2 SeaFoam to the crankcase treatments that I would rather had not done in hindsight and used something like MMO for 500 miles instead. Anyway, the previous fill was Mobil1 AFE just before going to Amsoil. I added Amsoil's enginge/transmission flush product just before dropping that oil out. I know it's cleaner now but haven't pulled the valve cover to see how clean.

Per crazyoildude:

1. "my northstar"
2. "my dodge 3.3"
3. "my old Cadillacs"

I've also seen an anecdotal report of someone with a car similar to mine (a Sonata) who reported more valvetrain noise with a P1.
