This filter is off a 2015 Honda Civic 1.8L. It was in use for 6878 miles and 1 year. The anti-drain back valve was still pliable and holding oil. The media looked good without any tears. A TG7317 when back on in its place.
Fram TG7317 C&P
- Thread starter OneLonelyBurrito
- Start date
Half super tech and half Castrol gtx full synthetic. Both 0w-20
The date code was A31421
Made the 142nd day of 2023.
Is this an economic move, or just what you had kicking around, or an out there idea, a frankenblend expected to get additional benefits from each brand?
It was just what I had laying around in the garage at the time and wanted to clear out.
does the seam have a metal crimp?
Yes it does.
I do this all the time. I pour in the last of the open jug, then fill the rest of the way with the new jug. Usually it is the same brand, but occasionally it is different brands.
Looks good. If those are short trip miles I would move to a late Fall / Early Spring OCI schedule for PA. FRAM TG high efficiency media won't take kindly to loading up leading to long bypass events.
Now, to counter or moderate my own suggestion a tad, I see this OC is near Winter so that's a good plan.
Thanks for the C&P.

How do you know what the dP vs flow is? If you don't know that, then making a statement like that is a shot in the dark with nothing to prove it's true. We have seen actual proof here that a high efficiency oil filter can also have a relatively low dP vs flow. The amount of media area plays a large roll in the dP vs flow and holding capacity performance factor.

Not shot in the dark.
Given the "non premium" cellulose media spec and the small filter area it will most certainly be in bypass often at low ambient warmup.
This is not multi-layer, screened back, thick synthetic fiber media construction.
But I have yet to see cold-flow filter testing with a real use, gummed up unit where I could present data to make my point.
Below is Cold flow graph (from J.P.'s Brand Ranks) on the Fram series of filters. A viscous test fluid** simulating a +3 deg C. sump

If the oil is cold enough, and if you revved the engine high enough before tbe oil warms up, pretty much every filter is going to have a high dP compared to when the oil is warm or hot. Lots of factors involved effecting how it may bypass in very cold start-up conditions.
This is why it's always a good idea to get the oil pretty warm before hammering the throttle. At 2-2.5 GPM all those filters are relatively close in dP. When the oil is hot, the dP difference even at much higher flow rates is only a few PSI.
