Crosland Filters

[mikenda - delete]

When I came to purchase a replacement oil filter for my Thornycroft T 80 I was offered a Crosland 672 in place of the original 368. This filter is considerably smaller in outside diameter than the 368. Thornycroft say that the 672 is the same spec but will have to be changed more frequently. Has anyone experienced a similar situation?

"Thornycroft say that the 672 is the same spec but will have to be changed more frequently" Its obviously not.If it was the same "spec" it would have the same flow rates, same cross sectional surface area, etc etc. If it was the same spec it would need changing as per the other one.

Crosslands are ok, but I've been using Purelators for a few years now. They're physically bigger which gives a larger filtration surface but with a finer filtration medium. In short they filter out all the smaller crap but still have the same flow rate. Results are pretty good. Rebuilt my engine a couple of years ago and the thing has very little in the way of sludge deposits. The oil is not thick and black more of a golden colour to it. I do change the oil 3 times a year though.

And to be fair, the 368 isn't listed by Crosland any more.

There is a local shop in Portsmouth that sells them. You can also get the Racor filters from ASAP.

hihi re filters.........

three questions u have to ask....

one.....is the thread the same size...
two.....does it have a valve inside
three....does it have an anti. valve inside..

and lastly ......does it fit ....physically.....

indeed a crosslands 368 is 79mm by 91mm m20x1.5 thread..rel valve no ant valve
.............crosslands 672 is 80.5mm by78.5 m20x1.5 thread..rel valve no ant valve

now we could sit here all day and swap the numbers in coopers, fram,alco.champion,tj......etc etc etc .....but if it fits dont worry about it.

the most important thing that u should do is change it ...and change it often....as with the oil too........ you do pay more in a marina etc for filters....for example both the above filters should retail in a car spares shop for £4-£5....don t use halfords they dont have the quality in their own brand. but any of the above makes do.

theres alot of confussion out there but suffice to say its not like coffee.....there's one manufacture that makes an awful lot filters in Wales for other people to stamp their own name on.

best advice is min twice a year change oil n filter....use a 10-40 semi synthetic oil...total cost of both about £20-£25.....less acid in engine = less wear= more compression=less breakdowns.


good luck
