Which Engine oil?
The word "better" is not specific enough to be used in this context. API CF oil has a higher performance specification. The way ordinary mineral oil is caused to perform to higher standards is by adding a load of chemicals known as an additive pack. In some cases the additives have been linked to bore glazing in lightly loaded engines. Now, once the engine is run in, Beta seem relaxed about the API specification used where as other marinisers are less so. In the case of Beta I doubt using API CF oil will do any harm but I can not advise that you use this oil. My Bukh engine has a similar specification but I have been running it on API CF for some years because it is easier to get hold of at a decent price. As they say, the choice is yours.
