Just make sure you change your oil frequently (no more than every 5000miles), change your coolant every 75k miles and you'll be fine.

Resline means pistons spinning faster, (more explosions) more heat generated, valve springs opening and closing faster, more blow by, etc. will this hurt your car, no way. Will it decrease the life of your engine if driven hard like this all the time, yes. But who cares, we are not keeping a car forever, drive it how you want and enjoy it.

If you really want to see what a redline is, have an oil seal go on a diesel turbo'd car…. Even with turning the ignition off, the engine but scream like a wailing banshee until it lunches itself. This is normally due to running out of oil, but it can shake itself to death if bits of the turbo get in to the chamber also

I wouldn't say redline is set to ensure "long" life of the car, but it is ser conservatively to make sure no damage is done to the engine therefore making the manufacturer responsible. If driven like this all the time though it sure will reduce (i would say slightly to moderately) the life of the engine.

Thanks everyone got the answers I was looking for! Just felt the need to ask since my dad helped me buy the car he says it isnt good to push it the way I do lol but Im a rebel its in my Genes

[MGT81]

You probably can. But why bother? Seems juvenile/like a waste of gas to me

[stanlalee]

You aren't hurting anything. In first and second you aren't there long enough to matter. I drive real aggressive and find this car impossible to drive in the upper rpm range. If you were really driving like Nascar constantly and steady state driving about 6000rpm sure you'd wear it out. A nano second at redline isn't hurting the engine. If it did your redline would be 1000rpm lower from BMW.

Where did I read of BMW"s engine dyno endurance testing? They test out the engine design (not every engine coming down the factory line!) by doing crazy stuff like run it to redline, hold it there, let it heat soak, then throw a bath of ice water on it to super-freeze it. Then repeat. Over and over again. Then, after thousands of miles of this they take everything apart and look for abnormal wear etc.

Modern engines can take a LOT of abuse. Now the other components (i.e. turbos, intercoolers/radiator, etc.)....

So what do they do at the home country where they sustain high RPM for MINUTES at a time?

They are no where near Red Line. Even the 6MT would have to run over 170mph in 6th to make red line & the 8AT a lot more, assuming it has enough power to pull the OD ratios to Red Line.

Wonder how many posters are engine development engineers or even race engine builders with all the free advice being given out with such certainty.

Basic physics, the faster you run an engine the faster it wears.

had a e92 328 a few months ago, I redllined the shxt out of it and at 89,000 miles it still ran perfectly and never used any oil... I did, however, miss-shift on one occasion dropping it into 2nd instead of 4th at 85 MPH... Engine exhaust valves were toast with major imprints on the pistons.. With that being said, I plan to redline the Shxt out of my 435i MT but with 1,000% more caution.

I used to really beat on my cars as a teen (88 CRX, 93 Sentra SE-R, 00 Legacy GT) and they usually saw redline multiple times a day. I put over 100K each on the sentra and Subaru driving like this and they still ran great with no abnormal oil loss or burning. CRX rusted away before it's time.

Hell, I was moving my brother from NY to El Paso and had his suzuki Reno, which is a re-banded daweoo at or around the limiter for almost a half tank of gas in New Mexico. Car ran fine for the 5 years he had it untill he traded in in for his 2006 330.

Drive it hard, just wait for the oil to warm up. You will be fine.

Leave it in third and run it to redline. You don't have to shift.

Have you tried to take a car to 120mph from 60 in 6th or 7th gear? You're not getting there without being run over unless you're willing to spend extended time near redline in some of the lower gears.

If what you say is true, no BMW in Germany that sees extended time on the unrestricted portion of the Autobahn is going to live to see the end of their warranty .

hey, don't bring logic into this.

Redline = max rev engine can go before it loses power significantly even when rev'ed higher. Most BMW's engine max power/torque comes in around 1k rpm before the redline anyways (depending on model/engine variation).

Holding the rev at the rev limit doesn't really makes sense, it doesnt make the car any faster/ engine respond better/ any benefits at all.

I quite often Redline my JDM cars (both the RX-7 and NSX) because they are build to make the most power near the redline. Will it decrease the life of the engine? Yes, i believe so. But not by an exponential amount. The engine itself and many of it's components are wear and tear items, so it is inevitable that if you push it harder, rev it faster, it will wear out sooner. But as long as you take care of the car, make sure it is adequately lubricated with fresh oil at more frequent intervals, cooling system runs nice and cool, replace components like plugs, filters, pumps, etc more frequent (as a preventative maintenance), you should be fine.

Good Luck and have fun red-lining!

Ram both my M3's at readline quite a bit.
Both had rev limiters and I'd let them bounce off the limiter.
The biggest issue is there isn't normally a lot of power at redline.

For the record, both my M3's were sold with the original motors still strong at +200K miles.
Redline didn't kill them. Always warmed up and always used Amsoil synthetic.
