Little note about Range devices. There was a thread awhile ago (don't recall the poster) that said something about if leaving the Range in all the time it might affect the gizmos that operate the cylinder deactivation, which could lead to lifter issues. IIRC it was suggested to pull the Range every once in awhile to let the system do its thing so that parts get properly used/lubed or whatever it does. I pull mine around every 3K miles for a short hour cruise then plug it back in when I get home.
I don't honestly know if the lifters would actually be harmed by not doing that but I figure it's a good preventative measure if there's something to it.

I have read most of the threads and like always several point out issues or potential issues. An equal number enthusiastically endorse w/no problems. I have had 1 for little over a year and really liked it. Couple days ago drove 15 miles and noticed check engine light on. Everything seemed OK. Drove about another 30 miles making a few stops. When I got home I took out the unit. Next day made 2 trips equaling about 40 miles and the check engine light was off whole time. Next trip I will put device in and drive, see what happens. Was the device causing the light ? Have no idea.

I haven't seen any comments about the "no name" range devices on Amazon. $89.00 and has good reviews. Anyone have one????? I might kick it... Can always send it back.

Good info.... I would probably NOT use the device while driving long distance as I'm happy driving 75mph in 4 cylinder mode. 28ish mpg. I also believe not enabling the system could cause issues. But removing the Range device a couple times a year, is probably good advice.

I remember that I had read that if you use the Range and it stays in V4 mode a long time, like on the highway, that the Range would revert to V8 mode for a while to lube the components of the engine on the deactivated cylinders..
In the same article it stated that same condition would result if you did not have a Range and the car was in V4 mode too long, highway trip, the ECM would turn the V8 mode on for a while to once again lube things up.
Can't remember what article it was in.
