Thread: The Best Oil Filter I Could Find

I don't know what vehicle you have but if it's a 300Tdi then be careful with the Z9 as it is longer than the spec filter.

Way way back the previous owner of my ex Disco fitted a Z9 and I found out the hard way. On full front suspension compression driving through a dip on a country road the differential had punched a hole in the filter...I was very lucky to get away without major damage to the engine.

Im not sure how he did it maby he was trying harder then i ever have. Did he lose the sump at the same time the filter does not seem to hang very low to do it maby i am wrong

You are wrong if it is a V8 3.9 with an oil cooler. OK in a 3.5.

Well I was the bunny who found out and no it wasn't as a result of over exuberance. The top of pumpkin on the diff is exactly lined up with the bottom of the filter and with (soft)standard suspension every mm counts.

and ill have to measure it on the weekend some time, you can never be too careful after all that is why there are shorter versions of a lot of filters. my car is raised 50mm also

FYI another common filter that shares the same thread and seal size as the Z9 and Z89 is the compact-sized Z418. It is common in Toyotas including the later 6 & V8 Cruisers, Hiluxes and Prados. It is about 10mm shorter and 15mm smaller in diameter than the Z89.

There are other baldwin and the like that will be shorter. Just be careful of the seal size. I have a variety of options for the D2 from 100um to 2um but some weep as while the dimensions and thread are ok the seals are slightly different.

Yep, a Z9 size filter on a 300Tdi hits the top of the diff.

Judicious grinding of the top of the lift out centre can alleviate the problem but doesn't entirely fix it. (well, it mostly does, I can go twelve months now without a mark on the filter but it can kiss it under extreme bump stop compression. Takes about 22mm of bump stop compression to do it, but it can still happen)

BTW, Beta2 and Beta75 numbers only tell part of the story in regards to a filter.
While the HPG filter is very good, (and one of the best) Donaldson's P169071 and Fleetgaurds equivalent Stratapore filter beat it in flow and capacity hands down while having the same Beta2 numbers. (beta2=6, beta75=22)

I've listed specs for a stack of oil filters in the past but can't seem to find them ATM.
