The manual states that the oil gauge percentage will decrease based on the engine revolutions. So, it may be very accurate actually. I cant know if its a linear on exponential function there by observing just a little part of the graph. Will see. I wont change the oil at 5k, unless its getting the gauge at 15% (as the manual say) Yes, there will be a 15% there... then it's time to plan an oil change.

Now... my next question is to get my own 0w20 and go with it at the dealer or just let them put their oil? I will ask them if they use the 0w20 but they could be ignorant and say.. "sure... of course its 0w20", then use the 15w40 they use on any civic....

I'm not a freak, I'm just wondering what path to approach in order to make things right...
