Do you have Marvel Mystery Oil over there, its an old and tried recipe? It can be added to both the oil and fuel and keeps everything clean, I have 68,000 miles on my +8 the internals are still lovely and clean having never had to replace the injectors, etc.. You wont see any black smoke or other indicators of cleaning.
Another trick used by some Morganeers is to remove about a litre of oil and fill with ATF transmission oil run for approximately 100 miles and then change the oil. ATF oil has some great cleaning properties.
