does anyone seem to get through far too much petrol with their ST. I can't seem to get a good mpg, i've been driving slower, driving in high gears and still it gets to 29mpg. whats going on? how else can i get it to 38mpg? i can literally watch the fuel gage go down as i drive, its eating fuel like there's no tomorrow. help me please? thanks, Sam

OK - eco warrior to the rescue

First things first, don't dispare as if your car is new it will have god awfull economy until it beds in. I'm not sure how much of this is due to you getting used to it or engine beeding in, but after a few months you should see 30mpg with normal driving.

Next thing to do is fit an ecotek valve and you will see an almost immediate improvement by 8-12%. So far I think I'm the only guy to have quoted improvements but JJST should be following up and dark little poet show provide more data (hopefully they're recording data and I'll be happy to plot it).

Finally - drive smoothly; the ST will provide 32mpg sitting well above the speed limit as long as your foot stays steady. Even with my ecotek I can vary from 22.5mpg on my favorit road to 45mpg plus on a long motoway haul......

Next on my list is fuel type but got no data yet so can't comment

whats better worrying about a few mpg or worrying if u can slow down in time for that corner on contry road???

LOL - worrying about fuel consumption doesn't have to take away from the fun of driving. I have shown that you can get a 10% saving without effecting performance which for me translates into approx £200 per year saving based upon current fuel prices.

Rather £200 in my pocket than someone elses! - 5 weeks worth of fuel!

Also - and I understand that most people don't give a damn but you can do your bit for the enviroment by worrying about fuel consumption so although you'll never catch me walking to work it doesn't hurt to save 10%.

Oh, and if you're worried about if your acr is going to make it around the corner then I'd suggest maybe slowing down..... you might just get there faster and with more fuel in the tank at the end!
