And congratulations for being (one of) the first owner of a Velite to post here!I've got a Chinese Version of VOLT 2016 Buick Velite 5 .
GM designed this car to take care of itself. There are TWO modes used to do this
MY 2017 just went through the FMM this past June when it forced me to burn off all the gas the dealer put it when my Volt was delivered in Aug 2016. For me it was a waste of 6 gallons of gas.
Also suggest down loading the Owners Manual PDF from Chevrolet's web page.
Good luck and welcome aboard. BTW where are you located.
The car keeps track. There's no need to do it yourself.Thank you for your suggestion .
I plan to run the engine twice a month , I'm in Shanghai CHina, where are pretty humid .
