Simple poll...Do you get better economy using cruise control or modulating the throttle with your foot?

My answer is OFF. Drove 160 miles to family at the other end of the state, cruise control off most of the way, averaging 75mph for half the trip and 80+ for the other half, (with other miscellaneous speeds including triple digits, lol.) Saw 25.2mpg from this. Coming back, I had cruise set to 74-75 for 95% of the drive and I got 24.1mpg. It was me and a couple bags in the car, and the way down yesterday was pretty windy. Tonight on the way back, not so much.

I don't think I've used mine a dozen times in sixteen years. Even on the interstate, down here with snowbirds and other idiots it's difficult to set a speed and keep it for more than a few minutes. Not worth the aggravation.

For me it depends. If I want to, I can get better economy than the cruise control by allowing the car to slow down going up hills. But I don't really notice a big difference either way, it's more about making my life easier on the interstate so I don't have to watch my speed all the time.

I usually let the car cruise up hills, it's down that I usually turn it off. I don't like the way the AX4N brakes to slow the car. This is usually on a pretty good downstretch that I'll turn it off.

I got my 30.5 MPG figure cruising at 65 most of the way.

I don't see an appreciable difference but that may have to do with a lack of level terrain in our highway driving. I use the cruise more as an anti-citation device than as an economy feature

I think with a maxmileage foot there would be negligible difference. On a non congested highway with consistent postings its quiet convenient, But if your tapping your pedal and hitting resume every 1-3 miles your mileage may actually suffer.

same here, although i do get better gas mileage running the speed limit running 5 or less mph over the posted speed limit.

I would say that I do get better fuel economy with using cruise control, however my 5 spd 3.8 mustang gets way better gas mileage even if i drive it like i stole it.

I am a staunch believer in CC. This little device can control the throttle better than my lead foot and is more sensitive to terrain and different road conditions. Went on a 3,000 mile trip in April and averaged 30+ mph with my highest being 35. This is on a '97 Taurus with the DOHC engine and close to 160,000 miles. I even use it around town.

I always use CC on the highways and country roads. Today I was on a country road doing 90KPH. Long straight stretch, flat and very little wind... Fluctuated between 40-41 MPG.

Straight stretch on the 401 at 107KPH, around 36-37 MPG.
