i use castoral edge sport 10-60. not cheep at £55 for 4l but it is what i was told 2 use or millers.
funny how evary1 recomends silkoline as its so good. it is allso £45 for 5l. might just be that its cheeper and may be ok but who says its the best?
think a mag needs 2 do a test on this subject soon.
