why does my 2005 civic ex rev so high on the highway? Are the lx and dx like that also? It's 4K at 80 mph. 3500 at 75

sounds normal

lx/dx are going to have lower RPMs for a given speed because they have a different transmission gear ratio. Longer gears in the lx/dx, shorter gears in the ex because it's sportier.

not sure where you live....but there is nowhere in North America where you should be driving that fast to begin with,

If traffic is moving that fast, you better keep up.
Slowpokes cause accidents. And road rage.


In my area, 10 over the posted speed limit is the expressway/interstate norm just about anywhere it's reasonably safe to do so. That means running 80 MPH here in my state, you'll see groups of cars all running at that speed all jockeying for position to pass the law abiding citizens in the slow lane.....and I tend to look for the packs running 5 more than that.

It's nice to be able to click off a 150 mile trip in under 2 hours.
My gas mileage is absolute crap at that speed though.

Fast lane is going 75-80 mph slow lane is 65. Or like on the I-5 near Bakersfield people drive 90 mph haha

And I'm going on a long road trip across the US and I will be on long stretches of desert highways.

Same here in Florida...cops usually don't ticket at 80 mph unless they set speed traps.

I once went through a good portion of Kansas (an eternity in hell) on I-70 at about 90-95 MPH.....It started raining, that's when I discovered the wipers didn't even touch the glass at that speed. They literally floated above the glass and couldn't wipe water. (1984 Mazda 626)

Slowed down to 70 and the wipers worked fine again LOL

I can neither confirm nor deny that there are nice, LOOOOOOOONNNNGGG stretches in Colorado where you can see for miles, and, when I drove through, wasn't patrolled... at all... lol
