on the freeway? im a little concerned about what stress the engine is having by 60 mph on california roads. or is it having any stress? what speed are you guys "crusing" at? what rpm's?

 

I so 65 most of the time and between 75 and 80 on the interstate everyday to and from work. RPMs are right at 4000 doing 80 MPH. I worry a little too but it is a Toyota engine so I think it will be alright.

 

moved...

 

Toyota engines seem to be built to spin, so I don't have any problem with running them at reasonable freeway speeds.

Remember, Briggs and Stratton industrial engines run 3600RPM, day in and day out, and they are hardly as well-engineered and built as a Toyota car engine.

I flow with traffic, cruising anywhere from 65 to 80.

If the revs on your Scion seems high at freeway speeds, then I'm guessing you're used to driving big American iron.

 

well put my old car was like 70 mph at around 3K rpm i think if i remember correctly i do know at 63mph it was at 2300 rpm

 

I drive 70-80 mph in Reno, NV very mountaness (Sierra Nevadas). Heading up a mountain I get up to 5k rpm, but not for any extended period.

 

somewhere just under 80, seems to be comfortable, and still real easy to slow down if coppers in rear view...

 

By the time I get done going through the gears, I'm going at least 65-70. I have to TRY to keep mine under the speed limit...

 

It's the cops in front of me on the side of the road with the laser guns that worry me the most.

 

i normally try and drive around 70-75 on freeways and i'm not worried at all. only time to worry if if u were to run at like 6k for a long period of time.

 

70-85mph for about 1/2 my driving..then stop and go for the rest

 

On the freeway I cruise at anywhere between 75 and 107 mph depending on traffic...I use the rule of thumb of go as fast as you can.

 

I don't like to take mine much above4k although I have taken it up to 110(don't argue or debate it because that is not the purpose of this thread)

70-80 here on the Interstate,If I dont I'll get run over :?

 

75-85 on our interstate

 

70 - 80 on the freeways... usually can keep between 3k and 3200 rpms

with my exhaust it sounds nice...

 

Whatever speed I need. Seriously, they planned this stuff out, don't worry about it...

 

Yeah, what he said. Just keep the oil clean, and maybe change over to synthetic to get a better viscosity, and no crap floating through the engine at such high RPMs.

 

I usually drive 75-85 mph on the freeway, but sometimes I drive as fast as 90-100+.

I wouldn't worry so much about it. Any new car engine in good working order should be able to run at 80-90% all day long in normal temeperatures day in day out without failure. The run the engines at WOT for extended periods right off the assembly line to help seat the valves and weed out any manufacturing errors.

I've driven to Sedona from Phoenix (a mountainous highway drive, lots of hills) in the summer when it was 90-100 degrees and I was able to maintain 70-90 mph all the way up, with the A/C on and 2 passengers along for the ride.

The engine can be heard loud and clear at 4-6000 RPM, but it's nothing to be concerned about, I promise. That is what the redline is for. Let the engine warm for 30 sec - 1 min, stay out of the red area and you are all set.

No worries.
