btx5mg Posted March 9, 2011 Report Share Posted March 9, 2011 (edited) Hi Guy's drove my 3.6 CTS today from Bristol to London about 120 miles my first long run it, kept it to about 65 MPH on the M4 motoway, and got 28.8 MPG now thats not to bad at all. But with Fuel in the UK at £6 a gallon or $9 in US terms, it is getting silly money now. Edited March 9, 2011 by btx5mg pete Quote Link to comment Share on other sites More sharing options...
cdgrinci Posted March 9, 2011 Report Share Posted March 9, 2011 Is that an Imperial gallon or U.S. gallon; still 28.8 is pretty good either way. (converted to U.S. gallon equal 24 mph; typical) Quote Chuck '19 CT6, '04 Bravada........but still lusting for that '69 Z-28 Link to comment Share on other sites More sharing options...
btx5mg Posted March 9, 2011 Author Report Share Posted March 9, 2011 As it is a UK spec Caddy i think it is a imperial gallon. I think for a 3.6 255 bhp car that's good. As i said it needs to be the cost of fuel in Britain is mad most of it is all Tax. This is my first American car for 18 years my last was Z28 now she did like a drink.
