1NZ-FE engine spinning away on a long trip #4685858

Just drove from Carlsbad, CA to Phoenix and back for just under 800 miles in my new to me 2006 Scion xB with now 135K miles. For a large part of the trip out in the desert, the speeds were between 70 and 80 mph and that meant up to 4K rpm for a driving time of just over 12 hours round trip.

I'm still getting used to spinning that 1.5L engine that fast but evidently it's doing okay connected to a 5-speed manual transmission. I'm using Red Line 0w-30 engine oil and Red Line MT-90 in the transmission. The oil level was checked several times and the level dropped less than the width of the Full line on the dipstick, maybe 1/32".

The previous owner has service records for 3K OCI's with Castrol GTX conventional 5w-30.

I hope this xB will last as long as my 84 Honda wagon. I'm thinking of putting a piece of tape over the tach lol.

Don't worry about it - small engines rev hard, they're designed to do it smile

In development, engines are run at full load and max rpm for hundreds of hours continuously.
Your trip was nothing but gentle exercise and your engine hardly broke sweat.


Cable ties should hold it

Right, everything sounds fine in your description however, the tranny in these cars are limited but, 4K RPM is nothing! If Toyota used a 6 spd manual, you may have been downshifting more often just to make any power in these little engines...anyway!

There’s one way to reduce the RPM and that is to slow down, LOL


If you want the job done right......do it yourself.

NO NO NO NO NO and NO!
You got it all wrong.

You now have an engine that just "open herself" (is XBOX/BOX masculine or feminine?)

Enjoy a more responsive hamster wheelie.

My Yaris, open pretty good after going up and down the Smokies last fall.

And the tach problem it's easy: just look at the road ? :-P (Pictures or it didn't happen)

Motorcycle engines of almost the same displacement run much higher at highway speeds. 4K is fine.

I use my ECHO for commuting to work and back, and for a large portion of the trip I'm traveling at the speeds you mention or more. My 1NZ-FE hasn't died yet so I doubt yours will either any time soon.

You have a tachometer? Nice, my ECHO does not (but I do also have the 5-speed).

I'd proactively replace the engine--you can never be too careful with these sorts of things. I mean, that's a lot of rpm. Ships cross the Atlantic all the time with a max rpm of what, 100rpm? You've overstressed that engine, and I doubt it'll make it down the block now.

I used to run my 1.05 liter Vauxhall up and down UK main roads back in the 1970's. This might mean a steady 70mph for several hours, which was around 5000 rpm.I used 20w50 of whatever brand was on sale for 3k oci's. It ran up around 1o0k miles without complaint or developing and appetite for oil, and carried on for a few more years more gentle use when I gave it to my sister. Terminal rust ended its life at about 12 years old, not a bad lifespan for a British car built in 1963.

The math says 3100 RPM at 60, 3617 @ 70 MPH, 3875 @ 75 MPH, and 4133 @ 80 MPH. Engine torque peak is 101 ft/lbs at 4200. HP is 103 at 6000. Seems about right for the vehicle and typical driver who doesn't like to downshift when they really should.

Before circa 1975 or so, it was typical for engines of small furrin cars to spin near 4000 RPM at 60 mph, even with push-rod engines. My 1267cc Subaru, for example.

The Yaris 5spd is supposed to lower the rpms a bit. You could also go to a taller tire for a 3-4-5% difference, the only real issue is how tall 1st is. My winter tire set results in 4.5% taller gearing vs my summer tires, and 1st in the Focus is fairly tall to begin with so it results in a bit more clutch slip starting on hills for sure.

My point was this approaching the cars maximum speed, it was probably over 5000 rpm at 70mph.

No need to worry about high RPM by itself, however proper oil level is more critical.
