Wassuo Gs

So I had a question. I notice when I drive (Ds) that if I don't press on any gas but moving still, my MPG says its at 15-20. I understand we use gas when the car is on, but is it usually this low or am I leaking? Doubt in leaking as I don't see any.

I'm just wondering cause it's lowering my MPG (not that it matters) but if it lowers my MPG, Am I actually wasting that much gas?

Note this isn't happening 24/7, just on occasions. It usually says Im at full capability of the highest MPG (60 on screen).

I'm working off the dash screen in between speedometer and tach , as well as the one of the touch screen.

I noticed it cause I left my car on and I was moving going 5-7 mph in a parking lot and my mpg started at 16.7 (recently reseted) and I didn't price on the accelerator at all and it dropped down to 14.5 mpg. Just weird

 

Bump anyone

 

Calculate your mpg the traditional way. Do this over several fuels up of at least 10-15 gallons. This should provide better info than what the display is showing.
