Cruising regularly at 4000 rpm

Save a couple bucks on gas, put a lighter load on your engine, you'll only arrive at your destination a few minutes later than you would if you were speeding. It's not the end of the world to hang out in the slow lane doing just the speed limit once in awhile. Enjoy some music or a podcast.

Where did you come from ...... old man ..... just go back to reading your book .......



PS - the Buick forum is on the next channel over

Its because new 4.3 FD. With early model cars you would be at 3.2k or 3.5k rpm

Dude, shoulda bought an automatic!

Been doing that lately actually. I want this engine to last. Especially on shorter drives. On longer drives it's best to go as quickly as possible cause the longer you take, the more the traffic builds. It's a case of getting out while the getting's good

If it was an issues, they wouldn't put 4000 on the tach. It would jump from 3 to 5k.

Yes 401/407 I cruise along at 3500-4000 some days.
Idle most days.
I'm not understanding your question though. You don't have another gear. How did you plan on lowering your rpms?

That's exactly what I'm worried about

I usually try to shift gears at or just before 3k, unless there's a car up my ass then I let it ride out to 4k-4.5k to get more distance. I try to already be in 2nd gear by the time the car in front of me starts getting distance from a stop. But this often requires stopping an additional car length behind them beforehand.

Think of it less about the specific RPM and more about what % of the engine's max speed you're at.

4000rpm is roughly halfway between the range on our cars. That's the equivalent of 2700rpm on something that redlines at 5400 (like a v8 or something). No big deal.

Should I limit my engine speed and slow down? Really dislike this part about the MY17 final drive. Sometimes it really feels like a car better left to the track, not too perfect for daily driving. At green lights, I get left so far behind by normal econoboxes with their CVTs. To keep up I have to shift fast and rev and make all kinds of racket, meanwhile they just whoosh away. Anyway I'm ranting, back to my original question... so is it safe?

dude bro, I have no problem dusting smart cars at green lights. Prius' though, those things are damn fast. Shoulda just got the AT, then you could drag race those nerds.

4k rpm in 6th is a pretty good ticket I think, I'm usually at 3.7k.

I don't think that's the concern of OP. He's thinking total accumulated wear over time. And yes, cruising around at 4000 rpm WILL wear your motor out faster than at 2000 or whatever. It's simply piston feet travelled/vehicle distance.
