Ive searched and searched on this site but found no answer or similar question asked, maybe cuz its such a newbie question but ...

ive only had my evo for about 3 weeks (completely stock) and i just noticed that when im on the freeway , the rpms stay above 3000 when im 65 mph and up , (stays at 3,500 rpm when staying at 85 mph to be exact). This seems too high for prolonged periods and makes me think im wasting so much damn gas or hurting the engine in the long run, but am i wrong?

What are the typical rpms for different speeds? (im a aily driver by the way)

maybe the evo is built to be like this because i know for any other car, 3000 rpms for a while is not too good for the engine and wastes too much gas...

thanks for all input

 

If it's an SE that seems to be about right for highway cruising speed. That's why I like my MR (gotta love 6th gear ) lol But don't worry about cruising at RPM's like that. The engine will deffinately handle it.

 

p.s. I tried my first set of energy pills just because I wonderded if they really worked ( if you wonderded why i am posting at 2a.m.) lol .... God it's going to be a long day

 

yea an MR would have been sweet but yea i got the ix with no regrets though. so when do you shift to 6th? does it go back down to like 2000 rpms at highway type speeds when you do?

and those pills dont work for me, i drove 4 hrs straight one time after midnight and i was still falling asleep after chugging those damn rock sized pills

 

Haha no the final drive ratio is quite similar to the 5spd at about 80mph im at 3300-3500 in 6th gear

 

That gear speed is normal, and the mpg is not bad either. If you keep you heavy foot out of it you will be in the low to mid 20mpg area...

 

just remember, its a 2.0L working under a little load... nothing to worry about

 

The MR even with its 6th gear doesnt drop the rpms like ud think at highway speed.

 

Yeah those revs will be perfectly fine. My first road trip in the Evo to North GA had me worried about overreving the car for a couple hours straight. On the way back, I didn't even notice the tach anymore. I've done a trip to TN constantly between 3500-4000 RPMs for 200 miles each way. I was in a hurry, but if I wanted better gas mileage, 60-65 MPH right at 3000 RPMs is nice and comfy.

 

My MR is 3000rpm at 70mph in 6th.

Welcome to the world of 4 bangers.

These engines don't produce alot of power off boost. Keeping the rpm's up there actally helps by getting the rpm's closer to the peak torque area.


Notice the MR has a lower rated highway mpg, same engine and a little more weight. But the lower rpm's do have an effect.

 

My 9 is 3000rpm at 67-68mph in 5th

 

im at 30K miles and the majority of it is highway 75+ with no ill effects. drove from southern Arizona to South Carolina 26 hours straight no stops but for gas, and I was at a average of 25-26 MPG

 

Im doing 70MPH in 6th GEAR 3K rpm.
