I've got is250 awd and I use to ride on snow mode, even if there isn't snow because I can make more miles per galon... and here is my question - Everything gonna be ok with my is (gear box, etc.) if I ride on this mode ?

 

Sure, all snow mode does is limit the throttle and RPM. Though IMO getting that extra 1MPG per tank isn't worth driving a Lexus thats been reduced to a luxury Yugo with 80hp. But hey, to each their own.

 

i do the same thing because it's smoother around town.

the 1 mpg i save is only a bonus.

and no. you won't hurt ur car with this on

 

1MPG isn't much but I guess on the long run it will. I say just stay on normal.

 

No it wont hurt anything... although you might be telling your ECU that you like to drive like an 80 year old grannie

 

That's what PWR mode is for

 

I don't think you can save that much "miles" on Snow Mode.

The prius still get more gas mileages & drive faster than your IS on Snow Mode

But you can save more "miles" by reducing uneccessary weights.

 

I wonder if because of f-sport intake (insted of stock one) I'll make less miles per galon.... hmm
In my is awd computer shows that I make round 16 MPG... what about yours ?

 

Do it yourself. Calculate how many miles you drove next time you fill up. The computer is never right for me. It also says my average speed is like 30mph which is so damn false.

 

Don't rely too much on the computer mileages reading. I trust the computer when i'm on the freeway.

But the combine over mileages vary depend on how long you idles your car(traffic) gas peddle. Going down hill vs up hills. etc.

 

Given that it makes close to 0 difference in actual performance, I'm gonna go with no :P

 

Same here.

 

a 350 in snow mode does really well in the snow...
I used it the other day when we had some so-so snow fall here in NY
about 2-3 inches...but had some ice also..
snow mode actually did well in limiting the throttle in a way that the rear drive rarely slipped around ....mine is on a set of goodyear F1 allseasons...and it did pretty well in snow mode...

I normal mode I was ok also but it took more of me adjusting my throttle input to prevent the slipping and trac cont. kickin in...in snow mode I just pressed the pedal and went...
but yeah it takes a lot outta the 350 as far as that "get up and go" hit the gas and be gone feeling out of it big time...

 

Similar experience, as I also have the same tires on my car. The car behaves nicely in the light snow/ice we've had thus far, and also rain. I typically have to be trying to get it to break the rear end loose, otherwise it just doesn't slide.

With regard to gas mileage, though, I just leave it in normal where my right foot dictates the mpg.

 

slow mode?
