1st filter + oil change 100% synthetic for Volt #2 this last Saturday after 37,500 km (1.5 year). That is roughly 7,500 km on ICE range extender use for long distance trip.
So, over 80% were e-km (30,000 km) without any ICE involved... I forget to check exact % of remaining oil life (below 40% I guess) which is a computed mix between 24 months & ICE usage.
My wife and I test drove a 2017 Volt and were very impressed with it. She wants her next car to be fully electric, however I convinced her that Volt would be a better option and she test drove so far Focus electric, CMax plug in and Ioniq and the only one she liked was the Hyundai and now she really likes the Volt. Are they reliable? How much did your electric bill gone up in this time?
mum Chaos had a 2013 and just last week traded for a 2017. Her electricity bills barely budged she says, and she only had one glitch in the infotainment that was fixed at the dealer in 10 mins. Her overall fuel average was well under 1l/100km. Maintenance is minimal. She loves her 2017 even more. Chev really did a good job building the Volt.
It is just about the only alternative to the Tesla 3 I am considering for my commuter. Strongly considering.
So far, so good either with 1st generation, the Volt is a no compromise EV + range extender (or bi-energy car): either you have time & place to recharge and if not, fill up with gas to still going.
2012 Volt #1 (55K kms) from 2012 to 2014, then 2013 Volt #2 (38K) from 2016 to present. Feel solid, no rattle or battery degradation, my Volt #2 is 127,000 km by now.
Volt #1 bought new, items replaced under warranty: one rear door handle and one front strut shock absorber, 2 oil change on my arm.
Volt #2 bought used, driver side front wheel bearing replaced under warranty, 1 oil change was on me.
Sparkie is a 2012 Volt, to day it has 416,106 mi (still counting)

About electric usage, anywhere from 15kWh/100 km to 30 kWh/100 km worst of winter I guess, it depends of your cabin heating & driving habits too.
nb: ICE would run intermittently under -10C (when set very low temp parameter).
