Yup, I guess it is.

Update.

Ok switched off the JB3, stuck the car in auto shift and used the cruise control to maintain 75mph where possible depending on traffic on the M6 in the morning. The journey is 70 miles each way, 60 of which is motorway. Guessing I am about 80% of time on cruise control on the motorway section with the traffic congestion.

Results on 2 days worth are an average of 34MPG with me a 12 stone person in the drivers seat only.

Not too bad, but not brilliant.

Can you not drop it down to sub 70?

i expect sub 70 would feel plain odd though

Hardly makes any difference and becomes annoying with below average flow of traffic at the times I travel. Constantly having to adjust the cruise which dangerous trying to control car acceleration like this prolong, we have all tried it

Either that or having to constantly brake and accelerate to keep out of the way of slightly faster traffic.

75 seems to be the average comfortable speed and decent gains in MPG and length of journey

Convert it to gas ?

The gas kit probably won't cope with the full power of the car and will switch to petrol when booting it, I'm not 100% sure on this though because mine is only 220bhp and it doesn't switch on mine.
but if you are motorway cruising the gas kit will be more than fine.

I converted my ST220 at a cost of £2100 (included some stupidly expensive spark plugs) and since the start of April i have done 8300 miles and saved £814 so far.
