1. Our gas gauge isn't marked off in equal increments. There is one little mark between F and a big 3/4 (?) mark, 2 between 3/4 and 1/2 and between 1/2 and 1/4, and then 1 between 1/4 and E. (Assuming the big marks are the "quarter" marks.)

So, if the needle is right square between F and 1/2, is it down one-fourth tank? Or is it down a fourth when it is on the large mark between the smaller marks? This may seem inconsequential, but it is making me crazy. Anyone know the answer?

2. I often run with the compass on the Nav screen in "heading up" mode. I've noticed lately that the little compass loses its red (North) end a lot. In fact, it often goes all white when I'm going East, then when I turn toward the North or South, the tip of the pointer goes red again.

What the hell is that about? Does everyone's do that?

well, don't have an exact answers to your questions, but

1) i only care about the cruising range

 

I can’t answer your question either, but “forever” as far as I know, all
car’s gages show that the “first half goes farther than the last half.”

That always disgusted me, because it can’t really be rocket science to
coordinate the actual tank volume to the gage.

Your gage question is interesting, tho. Does anyone know if in most of
the newer cars gages they are more accurate now from full to empty?

jimm, i can see what you mean, but i can tell you that has something to do with marketing and psychology. i read this true story (forgot if it was ford or GM). long ago they had this linear guage, and they got a lot of complaint from people that the fuel goes too fast, etc.... for whatever read, they came up with this "brilliant" idea of doing it non-linear. the first half goes "faster", but the 2nd half seems to stay "longer". NOTHING else was changed. guess what? complaints on the fuel consumption dropped tremendously. there you go customer feedback

but either way, i don't know about other ls460l, my gauge has been super darn accurate. i usually avg around 460 to 480 a tank. right when it's at the middle, i usually see the cruising range to be around 230-240, and on my trip computer i see about the same number (meaning the miles i traveled). so it's pretty dead 50/50 for me when it says half tank

 

That fuel gauge story is true, and it actually went farther than that.

Dealers got a lot of concerned questions about oil pressure back when cars had oil pressure gauges, so they stopped showing numbers (started just showing "low" and "high", with a space in between), then later actually made the gauges show closer to "high" so people would stop complaining about low pressure.

Ditto for coolant temperature gauges - they made them where the needle stays a little below the middle when at normal operating temperature so people would quit worrying about overheating.

Seems a little information is sometimes dangerous in the hands of the "ordinary citizen", and the car companies manipulate the info to make the customer happy.

Well there ya go! Nothing like a happy customer!

Do u mean in KM or Miles ?? Because mine goes for 750KM for one Full tank ,,, which is about 466 Miles ..

 

miles. i am in the US
