What oil filter for my engine code

Hi all,

I keep been sent wrong filter from
Euro car parts, engine isn't the factory fitted and they won't listen.

Engine code is : EV018187


Also should I go 10/50 oil on a high miler as I'm struggling with oil pressure, oil pump already been changed and head gasket checked.

Once hot if revs drop anything lower than 1k I get a flashy light and oil pressure drops below 2 bar

 Cheers

Any links to decent ones much appreciated

Much love

not like euro to send the the wrong
parts lol

registration may be able to
help you out mate

may be a number of the old filter
if visable

Didn't really wanna go off reg due to diff engine, I think it's this
