High RPMs necessary to ensure engine longevity?
 

I've seen some posts over on Edmunds claiming that it's necessary to drive a rotary at high RPMs in order to preserve engine life. For example:

Can our resident rotary experts speak to this? I drive an AT, so if this is true I will have to make a point to drive in manual mode more frequently, as the auto mode shifts very early except when being driven fairly agressively.

its built to spin up. i make a point to try and redline at least once each drive, just to keep and gunk off the plugs and out of their little burrows :P

Great excuse to USE that wonderful motor. Just do it to be on the safe side. hehe

interesting...good to know.

BTY -- salesman told me its best to rev the engine up after you've stopped right before turning engine off so that it "clears" built up gas, etc. from the engine. anyone heard of this and would this be beneficial to longer life?

In regards to reving the engine before shutting it off, this is primarily used during short drives when the engine has not had enough time to warm up. Reving the cold engine before shutting it off will help against flooding.

I've heard the same thing about the engine liking to be revved high. I make a point of redlining it at least once a day. There's a nice spot after I turn onto the road I live on where I can usually run it to redline. My favorite part of my daily commute! :D

Honestly, officer. I was just trying to ensure engine longevity.

Probably not one they have heard before:cool:

I have a tendency to bounce off the rev limiter when the stereo is too loud. Unless you're watching the tach, you have no indication you've reached 10K, the engine is so smooth.

The dealer told me to baby it for the first 600 miles and then to "drive it like you stole it".

Just got past 600 and this weekend is the first decent weather in weeks!

I just broke 600 myself this week. I can't wait for the weather tomorrow and Sunday :)

a redline a day keeps the mechanics away.

all this talk of redlining!!!!

Each km i'm almost at redline given a break in the traffic!

seeyas, all this talk has got me in the mood for a squirt.

BS or not, rotaries love to rev. Aside from fuel economy, I see no reason to keep the revs down when the motor is warm.

baller.

Do you understand why we use mineral based oils? or why the oil is burnt leaving carbon deposits in the housings and on the plugs/rotors ?

There is only 1 way out, hard driving.

not to sound dick, but i'd like to hear an arguement for not redlining...the fact it burns the gunk out is enough for me to floor it, but i'd like to hear the other side...if there is one.

I drive the car sanely during the week for fuel economy. But then i make sure to redline it on the weekends to keep the stuff out, is that often enough. I normally don't take it above 4k rpms on the week days. I am practicing my self restraint :)

"We" don't use mineral based oils, perhaps you do.

Rotarian, you have much more self restraint than I. The weather's been nice lately and my last two tanks less than 14 mpg. Damn third gear is great at highway speeds.

I normally get over 20mi/gal

I believe that i will get like 325mi or so on this current tank if the milage keeps going the way it has

how the hell do you get 325 per tank?!

shit i cant beat 200 on the highway!

wow, you need to get your thermo sensor checked out bad (one person had a non-CEL problem of the temp sensor failing and never sending a "warm" signal to the engine, thus running in cold-start mode constantly... sub 10mpg no matter how easy on the gas).

maybe a reflash would help.

i dont know my build date, but i bought my car in early febuary. shouldn't i have the flashed ECU?

I need to figure out a way to get mine flashed out here in germany..... Mazda dealers keep tellin me they cant :(
