Cruising regularly at 4000 rpm

Anyways, this conversation is redundant at this point.

Where the hell did I say anything about driving 4500 through the neighborhood? In fact I said it isn't necessary. I understood the point was about extra wear. It has changed?
Obviously the lugging applies to MTs since the AT will always be in the right RPMs for the speed unless somebody is in manual mode.

The only reason that the conversation is redundant is because you want to change the goals. You insisted that there was extra wear. I said there is not. End of fucking story.

I never moved the posts. I’ve always maintained that cruising at high RPMs (I was originally saying 4500 at 35mph, you said 4000) when a simple upshift would take it back down is unnecessary. The auto doesn’t keep you where you need for max accelerate. It keeps it as low as possible. When you need to accelerate it then puts it where it needs to be for acceleration. My point was, the auto isn’t a dummy. It doesn’t cruise at 4500 if it can do it at 2000. It isn’t redundant because I’m moving goal posts. It’s because I’ve said the same thing, don’t cruise high if you don’t have to for like a week now. Hahaha

I stand by my statement that there is extra wear at higher RPMs. I don’t think a single engineer on this planet would disagree on that either. The only thing debatable is how much extra wear.

Auto won't even cruise that high in sport mode, would have to go into manual mode on it to cruise at 4k+.

That’s because the engineers didn’t know what they were doing.

Who came up with 4500 RPM at 35 MPH?

I said earlier that I "cruise" at around 3300 RPM on the Highway in 5th and in the City drive around 4K and up. There's lots of cornering in a City...I drive the same on rural roads with lots of bends.

It's not doing any harm IMO except burning a bit more fuel.

If I anticipate the need to accelerate I will run a lower gear but not if I’m cruising for 15mins at a time. A big part of why the auto guys get better MPG is because the auto isn’t a dummy cruising at 35mph turning 4500rpm.

Anyways, there is absolutely no way you can tell me there is no extra wear at all what so ever at 4K vs 2k. Regardless of extra oiling.

You know like if someone gets sick of you hogging the left hand lane and decides to try to pass you in the right lane. I mean you have to be ready for an emergency like that. You can’t let someone pass you on the right. Right? Hahaha

IMO the car sounds like ass at 4K. Resonates like it’s ready to throw a rod through the block. 4K in an S2000 sounds cool. Not on the FA20 though.

Heal and toe braking, double clutching at revs and all those other super fun things cause more extra wear than driving at 4500 rpms ever would.

True. But with a reward attached. Cruising at high RPM adds zero enjoyment to the drive.

I did. It was just an example. Not directed at you or anyone in particular.

Unless you actually like the sound of the car which many people do. Besides you are once again deviating from the wear issue into personal preference.

C'mom Ermax, that's your opinion. Can't you accept that I feel differently and that it enhances my driving experience?

I like the sound of this engine at 4k and you hate it. So what? That's why we don't have one or two cars out there to choose from.

Dude it hasn’t changed. Give it up. My point all along has been that cruising higher than necessary will add wear and eats gas. It’s a freaking fact. If you personally enjoy the sound, that is your personally preference. But it doesn’t change the fact I point out.

The numbers look like it should be different but the engine does not care if it is doing 2,000 rpms or 4,000.

Let me ask you these questions:

What wears out and engine ......??

Why do engines wear out .....??
