BETTER mpg in 4wd...???
I noticed something odd the other day.
I just rolled-over 8000 miles on my '12 Sahara Unlimited.
I fill up about every 5 days.
I typically average about 17.2mpg and naturally it fluxuates a little each way depending on numerous variables.
Monday, it rained. I reach down and slid her into 4-hi (cuz wet streets are pretty much my only chance to use 4wd).
I'm be-bopping around, usual driving habbits, I glance down and see 19.2mpg
What the (heck) !?!?!
The best Ive ever seen is 21.9mpg and that was all highway...all cruise..from one fueling station to another...no stops.
But to go from 17 to 19 just cuz I shifted into 4wd doesnt make much sense to me.
I thought...bad alignment...wet streets will allow the tires to slip more and reduce resistance. But no feathering on the tires means alignment issue is LESS-likely.
Threads wander aimlessly....always refer back to post #1

"Hope" is NOT a strategy
