ok cool so with it in 8 it will automatically downshift?
Yes. It disables the MDS which is a waste.
A waste of what?
My fuel mileage is the same with it off as with it on.
Hmm, i never see eco come on when im in tow/haul on the highway
I noticed to day just cruising my 17 ram seemed sluggish in low RPMs and noticed the ECO was coming on more than normal. Has anyone else experienced this?
What I was trying to say is the MDS is supposed to save fuel. However, Me and at least most people here have found it to be so slight it’s not even worth it. At least what I believe is that turning it off around town seems to save gas and I don’t get that droan sound. Now if I’m on the highway I will leave it, but again any savings are very minimal. Also which I think is important is getting your fuel from a name brand station. I try to use Shell or Exxon. Maybe Costco once and awhile. I would say I also put 89 in it at least half the time I fill up. My running average is 17mpg on the lie o meter. Which is ok for me.
Only on 2500/3500 not 1500Tow/haul disables it too, correct?
Didnt realize they put a 5.7 in a 2500/3500...Only on 2500/3500 not 1500
A Nissan Frontier shouldn't need anything but 87 octane gas regardless of whether its the 4 banger or the V6. I quit buying 89 when the price shot up a few months ago myself. My truck runs just fine on Top Tier 87. Hell Top Tier 89 is $2.95 and going up.I never understood people putting the cheapest gas they can find in a $30k or $40k car. My Dad's Frontier is popping lean codes after he put in some low octane gas from Bucky's. I think it's 88 octane or something odd and literally only 8 cents cheaper. WTF?
