I've got a 4.0 V6 in my '07 Tacoma.

My rpms only touched 3,000 once during the 1,000 mile break-in. :-)

I've been doing the hill in first gear at around 2,500, which is pretty slow. But as long as nobody's behind me (it's a state road), that's what I do.

Thanks again

 

wow, I never really imagined that increased RPMs wouldn't really wear the engine that much...I always looked at motorcycles and formula one cars (which both have very high RPM rates) and you usually see the motorcycles run for about 90K and formula 1 engines are replaced after every race, usually...

thanks for feedback guys i'm starting to feel a little better about running at higher rpms although it still makes me a little uncomfortable....

 

It's all about what it's designed to do.

Using rdharper's logic, in order to decrease wear we should use overbuilt engines/electric motors and run them at less than half capacity. Unfortunately at such low load percentages they become quite energy inefficient.

Also consider that the rotational energy between 2500rpm and 3000rpm is NOT very much. Your rings and bearings don't really care. I think most of the engine wear comes from varying RPMs and lugging the motor, in which case high combustion pressure + low oil pressure = wear. This make sense to anyone?

 

Yah I see what your saying....so technically keeping the RPMs low on an up hill or anywhere is else actually causing more wear than going into higher ones?

 

How do you know if your oil pump and all your other pumps are in prestine condition...is there any test you can perfom

 

Fortunately, Toyota sees fit to provide a pressure gauge. (my Volvo uses an idiot light) The advantage of that gauge is it gives you a feel for how the pressure works from the getgo. As a new car owner you can make note of how the pressure is... under lots of conditions. That experience will be your best protection. If you pay attention, you will "know" when it goes bad, or starts to go bad, long before the pump quits on you.

 

You should use past tense. My '07 Taco has no oil pressure guage. All I get is a little red light. Thankfully, it stays unglowed.

 

Thanks for the info. I've never seen a Toyota without one... but then again all I've ever driven were SR5s.

As I said, my Volvo does not have one... I definitely miss it.

My Rx7 has one.

As you probably know... lots of people add aftermarket versions. I just can't seem to find a good place to mount one on the Volvo. So I make sure the oil is in good shape... and I check that the oil pressure light and oil level light are working at startup... the temp gauge will be another indicator of a problem... but maybe too late... maybe not.

Oil pump failure is rare... but it happens.

 

I don't see a pressure gauge on mine....

 

Interesting.. I have no idea, in that case, how one ends up with an oil pressure gauge. I do think most have them... but you've got me wondering. I only bought one SR5 new, in 1984.. long bed PU. I do not remember if there was an option package. Just assumed all of them had it.

Silly me.

Maybe we need a poll... (oh no Harper... not another poll!)

 

Please dont pansy your vehical, Its sickening.
Theres no difference in engine life if you drove it 2.5krpm or 4.5krpm, Only possibly gas milage and how many people you piss off getting onto the freeway to slow.
As long as you maintain maintinence on it there should be no way to blow it up, Unless you miss a gear and really redline it.

 

Wow, well that goes against everything that I ever thought...I always assumed that the higher the RPM was that the engine's rings (and whatever else there is to wear) wear off faster...thus, again the example with motorcycles and F1 cars....so why do they replace the engine in Formula one cars after every race...i read that the engine wears away with those high RPMs....

hmmm well if this is true than I will certainly be no "pansy" with my car....but i'm sure you can put yourself and my place...with no money...one car....and you can't afford it to die anytime soon. (has to make it through college) So under these circumstances I think my worrying is ok...but i don't want to worry so thats why I am asking....

 

Formula 1 engines are in an extremely high state of tune, and they're designed just strong enough to last through qualifying and the race (hopefully).

They aren't designed for longevity.

I've seen a few 5vzfe engines with well over 300,000 miles, and just regular maintenance. They still ran like new.

Maintain your 4Runner, don't lug the engine, don't run it at redline all the time, and it will be fine.

 

my engine doesn't really start to purr until about 2700 RPM. And at 3K in fifth gear I only do... about 60mph with my 22RE

 

my yamaha R6 hangs out between 12-16k all day, and LOVES IT.

 

Well Man, When I get on the highway, or go to leave town.. I take my rpm's to 4.5k on every shift and run at about 2500 on the highway, and have taken my truck to 110 mph and topped it out, jumped railroad tracks, slid around corners, and done more burnouts than I can remember.. And my engine runs fine. In fact my mechanic said my engine runs better than most toyotas hes seen, he guesses its because I drive it hard, broke it in hard, and it likes it.

 

my 82 and 86 and 97 tacoma dont have oil press. gauge my 86 sr5 did

 

Yeah, 3000 RPM gets me at about 65mph.

22R + CA Smog Equipment = ........... lag


But they can last beyond 350k miles if you change the oil enough.

 

That's perfectly fine and normal. It's actually quite good. It's really good to be honest with you. Your truck will last for millions of miles, (literally) that way.

It all depends on torque, gearing, and tire size.

 

My '93 does 70 at 3k in fifth.
