effect of different oil filters ?

[beanpole]

What effect does it have by not using the correct oil filter? for example there is very little clearance for the correct oil filter on my RV8 so I use anything else that will fit ie longer but smaller in dia.

Will this have a detrimental effect ?

Why are coopers oil filters recomended ?

Different filters will have a different element surface area than the "standard" one.
The internal construction will differ too.
There's actually a large variation between manufacturers when comparing their filters for a single application.

There was a post on here recently, which showed some info on a range of filters. (for a Ford 5.0 I think?)

Basically a smaller filter will be able to trap less crud before it goes into bypass. Just bear that in mind when considering your oil change interval.
At 3000 miles on a decent engine there shouldn't be an issue.

I've had the same problem. After speaking to Pilgrim an old style CVH escort filter is the same thread and almost the same diameter - it's just about 1.5" shorter which is enough to fit against the chassis.

Same advice i had been given though, you'll need to change the filter more often due to the surface area / capacity.

Steve, you can still get the shorter RV8 filter made by Mann, P6 I think!? Have the part number if required. In your case Steve I don't think the extra micron filtration will ever affect you or come to your notice, they are all a bit of a muchness. Worked for Crossland filters for a time which is a Lucas CAV company (not a lot of difference between the lot!) despite what it says on the packet! Eric
