Sean,
Are you syaing get the filters collected free of charge ?i have used OSS for 15 years. Only last year i got free oil collections becasue i am a member of R.M.I.F.and read it in one of the member magazines.If i had'nt seen it i do'nt think they would have told me. I pay about £150
every time they take a wheelie bin full of them.
On top of that i pay for Brake Fluid & Anti-freeze collections in 209 ltr barrels
