Default FAS/EOC with auto CVT?

My main reason for joining this forum was to get an answer to this question. I've browsed through some of the older threads in this subforum and seen that some hypermilers have used engine-off coasting (EOC) with their Insights. I've even seen some Youtube videos. I'm not sure if these drivers had auto or standard transmissions ... does the dashboard display look different for standards? If so, the cars in the youtube videos were automatics.

I had been led to believe that this technique was detrimental to automatic transmissions. I've seen advice that says not to use EOC if the car cannot be flat-towed. I looked for this in the manual but saw nothing about flat-towing, only that the car should not be shifted to neutral above 35 mph, so I assume that flat-towing is not recommended?

Is that advice to be taken with a grain of salt? What harm will be done to the transmission?

Was this thread meant for the 1st or 2nd generation Insight?

The 2nd generation is only available in a CVT.

Oh. :forehead slap:
I didn't realize that.

My question still stands. Is EOC bad for the CVT? If so, in what way is it bad? What will happen to it?

Hi Eli! If I have a GI Insight with CVT,can I use the EOC or LAS above 40 MPH?
Why would I need two joy sticks? Thnks! Rich

You seem to be implying that my question is stupid. OK, I confess I'm somewhat ignorant when it comes to cars. Please stop taking the piss and explain why my question is stupid. Especially when I seem to be getting contradictory advice from this place and others.

Whatever happened to "the only stupid questions are the ones that aren't asked"?

PS. If I misinterpreted the "joysticks" comment, I do apologize.

I don't know about the 2nGen CVT, you are on your own there. With the Gen1 CVT coasting is not the problem. Stuffing it back into DRIVE at speeds over about 4MPH will destroy/wear out the start-up clutch in short order. The start-up clutch simply is not robust enough to take that kind of abuse. You may want to keep abusing your CVT. If so, please report back with your experiences so we may all profit from them.

Oh, I'm not using this technique - I'm trying to figure out if this is something that should even be tried with the I2. I've been reading about pulse-and-glide with eoc for several weeks now and had come to the conclusion that the technique was not applicable to the I2 - it seemed to be a technique more suited to cars with standard transmissions.

Then I came across posts in this thread where the people said they had used FAS while gliding, in addition to seeing the videos where people had demonstrated shifting to neutral and switching off the engine while coasting. So now I'm wondering if I had come to the correct conclusion. You seem to be confirming my original conclusion - thanks for your input.

Again, I'm a really good SQL Server dba and programmer, but when it comes to cars I'm clueless compared to most of you people.

That's not what he meant.. he cross posted. He was talking about MIMA for the 1st gen.

I wish I could answer your question, but I've never even driven a CVT Insight so I am not sure.

Darn! Sorry Rich. Joysticks, eh? Now I'm intrigued - guess I need to go investigate that MIMA thing.

Well, I'm still getting the impression that it's not good for the CVT so that's where I guess I will leave it until hearing otherwise.

The reason its bad is that the engine turns the oil pump and if you flat tow it you will run out of lubrication.

Even if you leave the engine running, pulse and glide does help mpg.

Ive shifted from nutral and drive countless times with no noises, motion, etc.
