Pre-filling your Oil filter at Oil change time....

[Mr Cerbera]

I inheited most of my motoring habits from my Dad and I've realised, over time, how many of us continue in that way until new information changes our habits.
The problem with new information is knowing whether it is correct.
Recently, while trolling the Web, I discovered that there were 'several' comments on the benefit, or otherwise, of pre-filling one's Oil Filter at Oil change time.
Dad had always told me to pre-fill them and I took it to be gospel, despite some engines being damn difficult to do this on.
The Cerb is a cinch, of course, so never a reason not to pre-fill.

However it was interesting to see this Vid to have my Dad's methods confirmed.

Hope you enjoy....

Excellent stuff!

I’ve always pre filled the oil filter as ‘best practice’

Notably as my fleet are oil changed on age not miles (minimal yearly miles) I don’t change the filter every time…as serviceable filter, filters better than a new one..

I think I heard that before somewhere, but never been able to find anything to back it up

So I regularly change the filter on my Smart between oil changes, so perhaps three times a year or more

The tiny cartridge filter takes no more than five minutes to change, only costs £2.50 each, and is probably undersized anyway

You've made me wonder whether that's a bad strategy

I'm doing the opposite with the Cerb, because I've nearly run out of the synthetic media V8F 8990 filters, and I change the oil very frequently

If anyone has any V8F 8990 for sale I will pay good money for them

Technology must have passed me by; this is the first I’ve heard of synthetic media filters. Do you use them on / are they available for the Porsche too?

What kind of price difference ar they to std?

A guy called David Brown got a batch made by Cummins, they were only ever available from him

He suffered health issues a few years ago, and is no longer repling to emails, or snail mail, which doesn't bode well

I asked on Rennlist whether there would be any interest in something custom made for the 928, and there was a very negative response, so I dropped that idea pretty quickly

No idea what the minimum run would be but it would clearly need a 4 or possibly even a 5 figure investment

I spoke with Dave back in 2018 about filters and he emailed me that he had something similar to a stroke, poor guy, and lost a lot of short term memory and his doctor had recommended to him to cease trading

I have a couple from him and I might have a spare (*will have a look tonight) and I remember reading around the same time on the Chimera forums that they were switching to Royal Purple 20-253 ones instead as the V8F ones were no longer available

and just for reference for everyone, and because I have a V8 one here, these are the dimensions of that one vs. the purple one that you can still get

20-253 (specs from website above)

Filter Type: Canister
Filter Thread Size: 3/4"-16
Outside Diameter: 3.690"
Height: 3.750"

V8

Filter Type: Canister
Filter Thread Size: 3/4"-16
Outside Diameter: 3.7"
Height: 5.125"

so the 20-253 is shorter which I guess is good for the Chimera guys as they talk about the Rover engine being tight with space

This is what the V8 one looks like for reference
