Or you can use Block/Oil pan heaters to preheat the ICE like I do in the morning before going to work and some times at work before going home. With 105k ICE miles my BlackStone Oil Analyses is better than when it was new, I'm going 13k ICE miles between oil changes. :smile2:  I really don't see this as a real problem using 0-20W synthetic oil anyways. :smile2:  The car is going to wear out before the ICE does.

I agree.  I mean, sure, if it's -5F outside, you're keeping it in EV mode without heat in the car, and then you hit the freeway ramp, kick it into EV Later and just hold it to the floor I would agree that's definitely less than preferable.

 

But if you can control your right foot a little bit and keep it somewhere in the middle and/or just fire up the ice for a minute before you get to the highway I really don't see a problem...

^^^ Agreed, but the reason to stay slow or light on the gas until the ICE can take the load is to not discharge the HVB hybrid portion deeply and have to recharge it all the way back up.  That is less efficient than keeping it more charged.  Discharge/recharge is less efficient than keeping the ice running at highway speeds with the hybrid battery full.

 

-=>Raja.

The strategy I use typically is to set is to EV Later a little bit before the onramp and then switch to Auto once the engine is running.  It will mix the EV and ICE until the ICE is warmed up.  When the car switches off the ICE after warm up and tries to go back to EV, switch back to EV Later and the car won't try to recover the lost capacity from the warm-up period.  

I believe it gives you the best of both worlds; using the battery to allow for a gentle ICE warm-up but not having to burn excess gas for battery recovery as Raja is pointing out.

This is exactly what I described in my post #15  :wink:

Don't fret about warming it up.  The CMAX is fuel injected and uses 0-W20 Synthetic.  There is no real reason to worry about "warming it up".  My guess is that the ICE would last for hundreds of thousands of miles or more.  In my opinion, the ICE is the last thing you will have problems with over the years.

 

More likely you will have problems with the CVT or some other computer controlled functions before you have problems with the ICE.
