At my last service (December 2013) I specifically instructed the garage to use Castrol Edge 5W 30 as it is the recommended grade for my engine, however they decided to ignore my request and used 10W 60 instead. When I questioned their decision they told me this grade would be better due to the high milage (was around 118,000 miles).
Can anyone tell me if I should stick with the Edge 10W 60 or change back to 5W 30, although the engine sounds and runs great I am a bit concerned the 10W 60 isn't suitable for the engine or turbo.
Any advice would be appreciated, thanks. steve
