You guys are so nice and responsive I feel like asking other questions haha. If you don't mind!
1) What do you guys think about the first 7,500 mi maintenance? How much was it? Can I just do an oil change at Valvoline and call it a day?
2) What if I want to do a very short trip (1mi) on EV mode only. How can I start the car making sure the ICE doesn't kick in when I press the start button?
3) Speaking of, I just tried to do a short trip and I could only do something like 0.3mi before ICE started. I had turned the heater off and the battery was about half. That seems short, is this normal?
4) Last question, is there a difference between AUTO climate control and manual in terms of how often ICE is used? I'm wondering about the heating case: Imagine I set it to 70°F (with AC off) AUTO versus manual with the fan speed turned at the lowest setting.
1. First maintenance will be due around 10K miles. It's only an oil change, so, yes.
2. You can't unless it's warm out, you have good SOC and you barely press the throttle. Otherwise, the engine will kick in and will run until it gets to operating temperature.
3. Yes. Normal. See aforementioned answer (#2).
4. No difference. A/C has no direct effect, but the heater is directly related. ICE will run while cabin is being heated regardless of auto/manual. The only exception to this is to use passive heating, but you've got to be constantly moving for it to work effectively.
A few thoughts (and thread references
) to build on comments above:
1 - The maintenance minder will let you know when/what action is needed. Oil change is the first maintenance that should come up, and will appear at 15% oil life remaining. The oil life calculation is an indirect/inferred measure, and seems to be based on time (~1 year) for lower mileage (<10k mi/yr) drivers, and distance based (~10k miles) for higher mileage drivers.

2 - In cooler temps, it takes a bit of stars/moon aligning to start and run in EV only. Some things that can help maximize chances for this:
- starting from a warm car (e.g. garaged or warmer outside temps)
- starting with climate control off (i.e. remember to turn off climate control before shutting car down and parking)
- starting with high/full HV battery level (i.e. high battery charge before parking/shut down)
- minimizing and/or easing into throttle use (i.e. baby the accelerator, stay in the lower half of the 'blue' range, etc)
- trying to engage EV mode immediately (i.e. press EV button at start; not always the right temperature/battery conditions to engage)
The basic gist is to minimize/prevent factors that would otherwise cause the gas engine (ICE) to kick in, because there's a minimum run time for it (and fuel efficiency hit) once it first engages from cold start. There are lots of good mpg/EV related threads throughout the forum, but here are a few to get you started:
- EV Mode - https://www.gen3insight.com/forum/26...d-ev-mode.html
- ICE Running - https://www.gen3insight.com/forum/15...s-ice-run.html
3 - On cold start (and in cold weather), once the ICE starts, there is a minimum run time for it. I don't know the algorithm or specifics controlling the duration, but it's noticeably longer than other times the ICE runs. If climate control was on and it was cold out, the ICE likely started and continued to run (consuming gas) for its minimum duration. Another possibility is that the throttle was engaged aggressively, which in turn engaged the ICE which then ran for its minimum duration. Eco mode dampens throttle movement, which is part of what helps with fuel efficiency.

4 - One difference is that depending on temperature difference, "AUTO" could override your fan setting and consume a little more battery energy (and require ICE sooner?) to get to the temperature set point target.
