How to reset AVG MPG computer?
Hello there Club Lexus community, I am the proud owner of my first Lexus, a 2008 RX350 Brandywine Pearl on black leather no navi and I so love it so far, but while trying to figure out how thirsty this vehicle is, I found out I cannot reset the AVG MPG display unless I refuel.
Is there any other way I can calculate partial trip AVG MPG rather than averaging the entire tank?
It is the first car (in about 12 other brands so far) to have such limitation.
Please let me know if I am doing something wrong or the trip computer is that retarded

Nope, it is that stupid. You have to put fuel in the vehicle to reset that display value. Besides, the calculation is not all that accurate anyway. Many here find it to be off by a couple MPG.

Agree, as mpg geek as I am, I guess I will just have to readjust to doing the math myself
This is one elementary engineering flaw/limitation. Why do they (the engineers) have to decide for me as to when I want or HAVE TO reset the trip computer??

Particularly since the old RX300 did not have that problem, and you could re-set it at will....

I believe all of the prior vehicles I have driven with such capabilities could be reset on demand. I think a good question for Lexus would be to ask what they thought they were accomplishing by taking this ability away. Serves no purpose.

But is it worth the hassle? and how accurate would the new reading(s) be?

Intermediate
Gauge Calculation: 12.2L / 100km = ~ 3G/62.5mi = 20.8 MPG
My Calc: @ $16.73/L cost me ~$1000 to (~60L) fill got 510km off it. 60L/510km = 20G/318.75 = 16.9 MPG
WTF?
Most of this is Highway!!

1 Hong Kong dollar = 0.1290 US dollars

Also, if they use Imperial gallons, the conversion is approx. 4.55 litres to one Imperial gallons, vs. the 3.8 litres of one US gallon.....

Price of Shell V-Power, for example, is approx. HK$17.49 per L there in Hong Kong. The price RuninRoach gave is less than that, perhaps a different brand or octane rating, but it confirms we are talking about the same units of measure. The price includes about HK$6.06/L in government excise duty taxes. Prices are also highly regulated and do not fluctuate like it does here in the US.
That is about US$2.26/L or about US$8.54/US Gallon.
A typical fill for me at the station is 15 US gallons. If I had to fill up in HK it would cost me around US$128 (HK$992) plus or minus some change.
15 US Gallons = 56.78L
510KM = 316.9 US miles
So,...
316.9 US Miles / 15 US Gallons = 21.13 US Miles per US Gallon
510KM / 56.78L = 8.98 KM per L
Believe these calculations should be correct for all the questions or comments posted above.

You can go to Google and simply type in something like the following and when you press return it will give you the result.
convert 510km to miles
Try it, it does work and is accurate.
You can even try more complex computations such as:
convert 8.98 KM per L to miles per gallon
