Cruise Control or Right Foot Control??

Wondering if any of you MPG guys know which is better to ride on the highway (that has hills) on an auto tranny with a tune?
Thanks,
Kevin

Re: Cruise Control or Right Foot Control??

The only problem I have is the CC can't predict the hills, so it will downshift on a steep hill but keep going down a big one and be 10-12 over before it lets off. I have only hand calculated CC cause a 4 hr drive on the right foot is rough to me.

Re: Cruise Control or Right Foot Control??

i have drove from michigan, to n.dakota, to new york and my truck has never down shifted.. our trucks are actually working harder to maintain a set speed going up and down the hills so if you can let your truck gain a few mph goin down hill and slowly back off the pedal rite befor it wants to downshift goin up hill it will save the fuel..unless its a steep hill. when on cruise control when you go up it probably sarts slowing down way to fast for the truck to compinsate for it then it has to mash it to the floor to catch back up thus using more fuel to get back up to speed... try that ive been doing that since i first started to drive.... you just driveing or you pulling something too? that might change the downshifting on cruise control but do what i said even while hauling and it will make a big diff.

Re: Cruise Control or Right Foot Control??

When pulling something my mpg will be out the window anyways . I'm mostly talking about DD, but I do live in the hill country of Texas so the hills are pretty drastic.

Yep, proper driving techniques will beat CC,
however, CC will beat poor driving.
give it a test.

Thats what I thought. But I could never get a solid answer. I don't drive like a jack ass, I'm burning liquid gold, and its about the same price as it too at $3 a gallon.

CC will work good on flat roads, on hilly roads you'd be better off with the right foot. Accelerating on downhills, accelerating slowly before you start on an incline etc etc.

One of them truckless bastards.

Re: Cruise Control or Right Foot Control??

Some of the difference may also be in the vehicle.
I had a rental car last weekend for a business trip (nissan sentra), and it wouldn't cruise worth a darn, and didn't have cruise. It seemed like it didn't want to drive the speed I wanted. Even when I was watching the speedo like a hawk, I couldn't maintain any semblence of a steady speed. This was on fairly flat roads where I can keep my truck within 1mph pretty easily.

Go ARMY!
