Post Subject: api CF rated oilHi Tony, I have a Nanni 3 cylinder engine in our 2007 canal boat. The engine has covered 1300 hours ..... mostly canal cruising use. The engine only idles when used in a lock. Seldom run to charge batteries. I have used the 15W40 api Cd rated oil from new but have a chance to buy 20 litres of Mannol api CF 15W40. Is this likely to be too higher a spec for a 1300 hour engine ? (The boat has summer use only ). Many thanks, Mark.
