We mainly use synthetic oil nowadays which is included in the price, but specialist oils may incur an extra charge (i.e. Castrol and Shell Ultra). Also, spark plugs are generally included in the price but some long-life plugs have a higher life expectancy and so are more expensive (can be a lot more) and could also incur an extra cost.
We are also able to provide AdBlue, one of the latest techniques used to clean up diesel emissions, as a part of your service at an additional cost.
