Is yours the Sporty ST? Great car, great engine too. Fords eco boost technology is far more efficient than people realise. I've heard a case where someone averaged 75 MPG (UK) on a 300 mile trip which for a sports hatch is remarkable!
It has to be both. Stick will basically always outperform an automatic in terms of fuel economy, but it takes a driver who is skilled to do it against some of the slick modern automatics out there. Nice numbers! Congratulations!
It's the standard, not eco boost. I'm not really a conservative driver, I'm usually around 80 mph on the freeway. Although I like to think I'm really good at predicting when other cars will have to slow and I'm quick to take it out of gear
