Hi Brian

Just a thought look into Teraclean, lots of members have been saying great things about this, cleans the inside of the engine, improves your emissions as well as improving your mpg.

I am going to be booking my In sometime over the next few weeks. L'll let you know once I've had done if you like.

I had my S Type Terracleaned about 18 months ago and noticed a vast difference in performance and mpg.  The Mobile Service I used advised that every 15k miles would do the engine very good.

 

A week after having it done I had to drive the 90 miles to Sheffield and the outward journey on a restricted speed due to road works on the M1 the car returned 53 mpg.  The return journey on a different route returned a little less, and the round trip was 46.2 mpg.

 

I would recommend it.
