Engine Carbon Clean. Worth it?

[Aerial Andy944]

I've always put a bottle of BG244 or Archoil6400 additive in my Golf every year and felt this was sufficient for the miles I do which is about 4k - 5k a year. Is a carbon engine clean that much better and how so? Just curious as going to be giving the old girl a pamper after 14 years and 66k miles on the clock.

Andy I use a measured dose of additive every fill as a preventative measure in both of my cars so I would say yours will need the shock treatment dose.

The BG stuff will keep the worst of the carbon at bay. Use a borascope down a spark plug inlet to see the condition of the engine. Injectors fouling up after many miles are a bigger issue than carbon IMO if you are regularly using a good engine cleaner and good fuel.
