driving at 4000 rpm: what is considering driving this car hard?

[hedron]

I have Subaru Impreza 2011 2.5l Premium Manual transmission. Third generation. EJ25 engine? Pretty certain that's the one.

So, tradition says to keep it under 3000 rpms. But tradition isn't always correct in all circumstances. Cars have evolved since this rule of thumb was devised. I'm pretty diligent with toping off the oil, as it does burn a quart every 500-1000 miles or so. Which is kind of annoying, but w/e.

1st gear 0-15mph, 2nd gear 15-25/30 mph, 3rd gear 25/30 - 35/40 mph, 4th gear 40 - 45/60 mph, 5th gear 45/60 - 75/95 mph.

All my EJ22 cars cruise the highway in the 3000-3500 range depending on whether I want to take the 4.10 car or one of the 3.90 cars and whether I wanna go 70 or 90. None of them are under 200k miles so it can't be that bad for anything.

That said, force on the rotating assembly goes up with the square of RPM. There are two ways of looking at this. The first is that 4k is way worse than 3k. The other is that if the engine can rev beyond 6k occasionally then nothing you do under 5k matters.

Driving at 4000 rpm by default I find it quite dangerous. So if you can consider it I think you should run 3000 as usual.

Never heard of 3000 rpm tradition. Around 4000 rpm is where the torque dip happens, which is probably why it feels natural to shift, and no it's not driving it hard.

If you are driving and attempting to get the best fuel economy you shift early and attempt to keep RPMs lower. I am not sure if that is what you mean by "tradition says to keep it under 3000 rpms."?

IDK, I remember people saying they baby their cars by making sure it never revs above 3k.

Those people are morons and should be taken out to the street and shot.

My typical highway cruising speed has it spinning faster than 3000RPM in 5th (5MT).
Would I recommend using 4th for the same cruising speed? Nope, upshift to 5th.
