I've always heard that the worse thing you can do to an engine is to start it. I'm wondering if that includes engines that were designed to stop and start automatically at lights and stop signs.

Another related issue is whether constantly starting the engine will shorten the life of the starter.

Any opinions?

I think what you may be concerned about is that the engine oil will drain into the pan after the engine has sat for a long period of time. I don’t think this would be a concern with a short rest period.

I’m not concerned.

Thanks, that makes sense.

What do you think about the starter being overused?

Both my Passport and my new F-150 have this feature. When I let off of the brake pedal, the engine immediately starts. It doesn’t ‘crank’ like a cold start. I would like to think that Honda beefed up the starter to accommodate this feature.

I’ve been going to a specialized Honda & Acura shop that is father son owned with my 1996 Civiic & 2006 CRV and they both told me the auto start/stop is awful for your engine and starter. They haven’t needed to do even an oil change on it yet, but I hope someone finds a hack to turn it off completely very soon. Other than my parking garage situation, it is the most annoying thing about my Passport. I still keep forgetting to turn it off before driving. Only at 2200 miles and that includes three round trip road trips.

Also, they have always told me to do a 1-2 minutes cold start warm up on my engine before driving.

Some food for thought.... Modern vehicles equipped with Start/Stop technology utilize reinforced starters coupled with High Capacity AGM batteries that aid in making sure the vehicles electrical system is essentially stress free. In addition, when the engine shuts off, the engine management system keeps track of the exact position of each piston. It can then restart the engine by spraying fuel directly into a cylinder (Direct Injection) that is just at the start of its power stroke and firing the spark plug to ignite the mixture. This will eliminate the need for the starter every time the vehicle starts from a stop (this does mean that the engine must be 'warm' as higher cranking amps are required to start a cold engine). Hope this helps....

Thanks, that helps a lot! I do need clarification on one point though; you say "this will eliminate the need for a starter every time the vehicle starts from a stop...". Can you go into more detail about this? Does this mean that the engine can restart without the use of the starter?

Yup! Thats correct.... At any given time there is at least one cylinder ready to start the power stroke (4 stroke cycle- suck - squeeze - bang - blow ?) and all that cylinder needs is a rich A/F mixture coupled with the ignition from the spark plug to get the rest of the engine fired right up.

Thanks again. I wasn't aware of this advanced technology till now. ?

I've never seen the Honda description of their system, but here is a good explanation from Mazda;

Thanks for the link. I'm sure Honda's system is very similar to this one.

I found this entire discussion of the start-stop engine restart fascinating! Automotive technology has come a long way since I started driving in 1962. I'm assuming the big jump is when the internal combustion engines were coupled with computers that managed engine functions combined with computer-aided engine design made all these advances possible.

I hate the auto stop “feature?” I always turn it off. Was told it did not do much for mpg either. Btw I do like the feel of eco mode around town driving

I am fairly certain auto-stop vehicles have an electric oil and water pump so fluids continue to circulate (at least in two other cars I have had this is true, you can hear the pumps operating).

One of the (operator options -engine?) settings override the auto stop feature, regardless of the dash panel selection. As I recall my salesman asked how I preferred it and then set it up, along with how the doors lock, unlock, etc. As I found this unobtrusive on my wifes new Ody I asked him to allow auto stop on my PP.

Later on I discovered using one of my key fobs engine auto off was enabled (and then controlled by the dash mounted switch) but using the other key fob auto off/ restart was always disabled. So obviously the key fob is also involved and could be toggled on (or off) again.

I'd like to find out how to enable auto stop to be "off" all the time. It's not covered in any Honda owner manual.

If you don't want to poke around the numerous selectable settings then revisit your salesman and ask him to change it for you.
