Just curious, I noted with a Mann Filter that the Oil pressure light would always take 1-2 seconds to disappear.
Since fitting a Bosch Filter the light doesn't even flicker..
Odd maybe, its the design of the filter?
What do filters do you all prefer?
Internal Non return valve fitted, maybe.
I usr what ever is cheapest at the time of Bosch, Mann, fram etc. No cheapies though
I've been mostly using Mahle filters and not noticed any significant delay in oil pressure light going out. OK I don't watch it like a hawk but a couple of seconds between starting and light going out I would notice.
I guess the difference between Mann and Bosch is down to the bypass valve pressure setting. Assuming both are standard 40 micron filters of same size with, presumably, similar filtration areas a lower pressure setting on the bypass valve would mean it opens more with cold, thicker, oil so you get a bit more flow early on before the pump has come up to speed.

Mahle, nothing but. When I bought my Classic it would take a good 20 seconds at idle after standing overnight for the oil pressure light to go out. Previous owner told me that he'd changed the oil and filter regularly and always used a good quality Britpart filter. Put a Mahle in and the light went out immediately and, upon investigation found that the Britpart didn't have any sort of non-return valve so the filter was having to be filled from empty every time it was started.
I've tend to use Bosch on pretty much everything. Only once has that been a problem as the filter would not fit, and that was on a Vauxhall Astravan. Mostly as it looked like the best option at ECP brand wise.
Good quality Britpart is that even a thing?
There are some utter crap ones out there - if you haven't seen it, this is worth a watch when you have some minutes to kill.

Given the Fram is the second cheapest out of the options on ECP, it makes you wonder how bad the Crosland ones might be.

Fuckin hell that's bad
Luckily mine uses a separate element so you can see the 'quality'.
I had seen that video, thanks for posting it here though. I love his true indignation about the low quality of the Fram.
Used to use only Fram on my cars as they had the correct hype, and that is what dear 'ol dad used! (Turns out, crap product to go with it!)
Having always used Wix for any marine diesels I have been in charge of, I gravitated to Wix for my trucks and diesel vans as well.
A good friend, and great engine guy told me to use "The best filter you can buy and, a good Dinosaur based oil" a long time ago. so that's what I have been doing.
He uses only the Napa Gold or Bosch filters.
For the last 25 years, I have been running Delo 400 15w-40 in the Cats (On the boat) as well as all my vehicles and generators, petrol and diesel
with no problems.
I have not switched over to full synthetic oils on the Rangies as I have had issues with it sneaking past main seals on a goodly number of
stationary power plant diesels. Any issues found by others?

He thought it was so insisted on using nothing but. When I bought the Classic it did need a few bits and pieces doing to it and half of them involved replacing Britpart bits with real ones.......
I've never found a difference in the rate that engines use mineral or synthetic oil. I use semi in the P38 as she leaks a fair amount and full synth in the XJ as it's reasonably oil-tight.
I tend to use Mahle or K and N, although I've never needed the nut on the end of the K and N because I don't gorilla them tight in the first place.

At least Britpart don't make engine oil
Just ordered 4 pollen filters for the rangy for £8.50 delivered.
CROSLAND item number 507670038 on eurocarparts
Nice one, just ordered 4 as well.
any name brand filter with a NRV. if you don't know the name or it has two names one in chinese , put it back on the shelf
The old Bus is reasonably Oil tight..
Weirdly..
I seem to recall seeing Britpart branded Oil, might be wrong though..
Used 5w40 Mobil 1 Fully syn.
Mahle or LR genuine (the latter's not expensive and the white cannister marked Genuine Parts makes me feel good when I'm in the engine bay - bit like buying Chanel for the wife)

Did you get yours? I got an email saying they were currently out of stock but would send them as soon as they were back in stock. Arrived today and even though their website shows that 507670038 is the correct part number for a P38 pollen filter, they aren't. Nothing like.
PM'd you Gilbert, then I accidentally sent it to trash, then restored. Just saying because I don't know if the restore worked properly.
Yes, got it and replied.
On the pollen filters, been on to Euro. The 507670038 is correct which cross references to a Crosland C40235P but the ones they sent were Crosland C40353P with the 507670038 number hand written on the boxes. The C40353P are for a Lexus. My local branch don't have any in stock so they've given me a returns number and DHL will be picking them up tomorrow. The correct ones will arrive sometime.......
There seems some confusion with the pollen filters generally, the guy with the p38 which we did the gearbox filter and oil on a couple of weeks ago ordered some through the factors he likes to use, and when he tried to fit them realised he had been given ones for a Hyundai which were completely wrong as well.
