Hi. My 1275 Marina engine has done about 57,000 miles on Halfords 15W50 mineral oil and then latterly their 20W50 Classic mineral oil with out any problems (so far!!).

20W 50 is the oil to use. Nothing fancy required for these engines. While the semi 15W40 would be ok in winter - it's a bit on the thin side for summer use......and far too expensive for a Marina engine!
