Need x 2 for Volvo Penta D41B
Usually use Fleetguard LF 3464 but bit expensive this time round, the Mann W1140/2 looks to be the best option.
The cheapest online supplier appears to be AUTODOC with Muller or Baldwin filters.

Comments welcome .
 
Call in at Earnest Doe at Dartford or Ashford. Get a commercial equivalent. That is what I do for all my filters.
Does have a lot of branches in the SE that one can call in to. Lots of other bits that would suit the boat owner for spares as well

Back in the days we had a Volvo engine I once (and only once) attempted to buy a 'genuine' Volvo oil filter. The local marine-volvo dealer offered me a Mann Filter, with an official Volvo label stuck onto the box for about 5x the price of the same filter in my local autoparts store; so I suspect that Volvo themselves have no concerns about using Mann filters.

MANN are one manufacture who produce filters for some OEM's. However (and I know this as I worked for the manufacturer at the time), it does not mean that the filters they produce under their own brand meet the same spec.

The filters we had made by our filter manufacturer (who also sold filter sunder their own brand - not MANN) were a different, proprietary specification that they were not permitted to reproduce under the supply agreement we had with them.

I'm not saying that pattern parts are necessarily a bad thing, I just don't like it when people jump on the anti-OEM band wagon without full knowledge.

Opie Oils often seem to be a fair price inc P&P when I order a batch of oil and filters.
Eurocarparts are often pretty good, with the advantage I used to drive past their shop most days.

Worked for a major filter manufacturer in another life and exactly my experience. Replacement market is cutthroat and not very discriminating. Heavy users tend to stick with genuine and in my view light users like typical yachts should also use OEM. We treat our engines appallingly. short runs followed by long periods of inactivity - 50-100 hours a year similar to 1-2000 miles of school runs. Extra cost of a genuine filter is roughly £5 . Why are some people such cheapskates?

Mann WII40/2 £ 12.10.
VP 471034 £21.00. in local chandlery £ 23.50

But only one of those is a genuine part.

The other may fit, but is not genuine so this compares apples to oranges. The only direct comparison is the VP price to the chandlery price, less than £5.
 
The fuel filter for our Yanmar works out at almost 60 quid with VAT at Yanmar dealer price.

I use - just had another lot delivered from Inline Filters - Baldwin Filters.

3 lube filters for main engine and genset - they are the same - and two engine fuel filters, 67 quid delivered.

I worked for Lucas service years ago. Crossland filters was a Lucas company. I visited the factory more than once and have a good idea of what makes an excellent filter.

AFAIK, no engine manufacturer make their filters, they are made by filter companies and supplied as OE fit in factory assembly and as spare parts for use in service.

If a filter from a reputable source matches the OE spec there is no reason not to use it.

40-50 years ago there were dodgy filters on the market. Honda motorcycles suffered parts pirating and took legal - successful - against, IIRC - Britax who were supplying inferior stuff.

Bad filter quality seems to be a thing of the past now.

This may be true, but I know first hand of two engine manufacturers that have proprietary specs on their filter protected by IP agreements for 99 years. Pattern parts for those filters may look the same and may fit, but even if they are made by the same filter company there is no way they can meet the correct specs.

Your second part is a very good point, and it is knowing if it does match the OE spec that can be difficult. Just because it spins on and seals does not automatically mean it offers the same protection.

Volvo or whoever may have specified a slightly different area of filter paper with a slightly different pore size.
Is it really going to keep the oil cleaner than a filter spec'd by every other engine manufacturer?
Who can say whether a slightly different filter might give better protection?
The optimum will probably depend on many things.

Parts suppliers make a lot of money out of OE branded spares. Sometimes they supply parts at a loss in order to be the spares supplier.
 
I've just insalled a new engine in the boat (the cost is fresh in my mind!!!) so it's going to get looked after with the recommended stuff. As they say in the motorcycle world -" if you've got a £10 head get a £10 helmet."
 
But we have heard of the Mann filter, in a Volvo box and with a Volvo label stuck on, showing the same Mann part number, being sold at many times the Mann price.

You are correct, Volvo MAY have specified a different filter paper and pore size. But pretty unlikely. ICE engine lube and filtration is hardly a new science, we have been at it for over 75 years. One could say the filter makers are ahead of the manufacturers in filtration requirements. Certainly the guys at Crossland gave advice to the motor industry on oil and fuel filtration.

I am currently talking to Baldwin Filters USA to asertain the micron size of the fuel filters I use on my Yanmar.

As they list it as an equivalent, they would be on a sticky wicket in litigation prone America should they be deficient in any meaningful way. Plus they meet all the relevant ISO Standards in spades.
