But that's not what you said. You actually said:

Turn of stop/start firstly.

You made no reference whatsoever to your vehicle, therefore it can only be taken as suggested advice for everyone. It was only when you were challenged on this that you started backpedalling.

So there is NO amount of time sitting still, that Stop/start will be more efficient, in your vast experience of your own car. Do you stop and start manually?

No back pedalling here, I stand by what I said.

Is there not? Ok ill take your word for it. And nope, never did. Can't imagine that'd be good for an engine.

8 seconds seems reasonable for the saving over idling, and lets face it most stops are more than 8 seconds.


If you're stopped less than 8 seconds each time (because you're driving forward a couple of feet and stopping again, or dipping the clutch to bring the engine back on), then you'll use microscopically more fuel with it on than off. But you'd need to be doing very low mileage, very slowly, to see any measured drop in efficiency.


So the only times stop-start is worse on fuel is the edge case where the road conditions don't allow it, or through unsuitable driving. It's taken me a while to get used to the stop-start and waiting for a gap to appear instead of perpetually crawling forward.

For sure you backpedalled ... post #2 in this thread (the very first reply, and by you) made no qualification at all that your statement would only suit people with your driving environment, therefore it can ONLY be presumed that you were making a definitive statement that stop/start should be turned off by everyone. As you now claim to not have meant this then you have backpedalled from that position.

Again, what's the euro regs got to do with anything?

Sorry... Can I just clarify your question here...?


Are you really asking what the Euro emission limits on unburnt hydrocarbons (applicable to any car built over roughly the last decade) have to do with the unburnt hydrocarbons being measured by your friend over three minutes versus a hot start...?

And, yes 8 seconds does loosely tie in with 10seconds. No it doesn't tie in with the 3 minutes refrenced above, but neither does any thing I've stated.

Great. So let's all agree that this three minute figure is a self-evident pile of steaming equine manure... and that nobody with a vaguest hint of clue could ever believe it's anything else. Right?

I've back peddalled but you've presumed? Intersting logic there.no back pedalling from me.

Coming across a bit hard of thinking there.
Slowly this time: why. Quote. The . Euro. Regs? They don't relate to stop start.
And the 3 minutes thing? Couldn't disagree more. The info is up there (all be it 2.75 mins -but what's 15 seconds between friends?)

More fool you then.

Why tell the OP to turn it off though when, even by your own admission, it’s not always the case that turning it off gives greater fuel economy?
