New car break-in period

Hiya folks. been watching a while, prob getting my Insight within the first week; still nailing down details. Question about break-in... I can't find anything in the manuals or online that details a break-in period. Any info available? Might buy one out of town but don't want to drive 100+ miles at 75 if that's not going to be good for the new engine...

Thanks.

The only thing I’ve ever found is this from page 454 of the full manual.

“During the first 600 miles (1,000 km) of operation, avoid sudden acceleration or full throttle operation so as not to damage the power system or powertrain.
Avoid hard braking for the first 200 miles (300 km). You should also follow this when the brake pads are replaced.”

I have many goals in life, but I'm abandoning my goal of having read more of the manual than Mr. Natural.

Wish they'd explain what "full throttle operation" is. Is that 75-80 MPH, or is that flooring it? Any chance that's an industry term?

Lol! I’m retired and live in Minnesota, so I have a lot of idle time this time of year. And the phone book isn’t quite the read it once was. 😛

I'd feel confident in saying they mean don't floor it!

I seem to be averaging 40 mpg and I've put 500 miles on my touring model so far.mostly highway driving. I drive it like a baby, which is irritating. I took it back to the dealer and they said it does need to " break-in". How many fillups should I go before I see an improvement? Or return the car for a "normal" one that I can drive normally and get about the same mileage with a bigger has tank so I'm not filling it up twice a week. Btw I drive under 70mph

Hybrids are more fuel efficient mainly because of the ability to run electric only at low speeds, or regen when braking.
So they get the most benefit in those driving conditions.
Driving on the highway, there is no regen, and the gas engine needs to run constantly.

On top of that if you have colder weather, you also lose the benefit, as the heat for your car needs to come from electric if the engine is not running.

So hybrids are not the be all and end all for all people.
Someone in stop and go traffic in warmer climate can save considerably.

Short trips in cold weather do kill the mpg as much as highway fast driving. Mine was getting right at the advertised mpg right out of the lot, but that was in the summer. I averaged around 44 on a 3000 mile trip in mid October with daytime temps in the 50’s. That was on mostly Interstates between Minnesota and Maine.

I don't buy this reduced mpg due to "break-in" idea. Here's why. In November I did a test drive in an EX. The car had 5 miles on the odometer at the start. I drove it over a very familiar road in the 40mph area, and returned the car with something like 21 miles on it and 60+mpg. To be fair, on my best days I can get similar numbers with my Civic Hybrid on the same road.. Also, I wasn't getting the best mpg the car is capable-of, because I spent most of the trip figuring out all the various controls, rather than seeking top mpg (a long time hobby of mine).

My Civic Hybrid's EPA mpg is in the low 40's. Yet for over 30k I'm getting in the low 50's mpg. I drive with and sometimes faster than the mass of traffic, in town; 60 mph on two lane highways (speed limit 55), 70 mph on the freeway (speed limit 65). Why the 10 mpg difference? After trying some things and playing with the numbers, the explanation I came up with is; 40% mpg benefit from extra air in the tires (4 psi), 40% benefit from basic high mpg driving style practices (avoiding frequent hard acceleration / hard breaking), 20% from specialized hybrid driving skills aka "hyper miler" or "ultra miler").

For those unhappy with mpg in the low 40's, please keep in mind that the EPA highway figure is 49 for the EX and 45 for the Touring. Put some extra air in the tires, and check / adjust the pressure frequently ( I got my own air pump and pressure gauge and check them once a month.). Finally enjoy the Insight's great handling, it's acceleration capability seems similar to "normal" cars of similar size and price, and it has the option of great mpg, IF ya make the effort to adjust your driving style to get it. (Many good ideas above)

I was also getting about 37MPG average for the first 800 miles or so (touring model, eco mode), but that number improved so I'm guessing there is some kind of break-in period with these cars. I'm now at 9k miles and my lifetime average mileage is about 43MPG (80% highway miles). I do see some rural driving trips as high as 70MPG, but my frequent highway miles, especially in mountainous areas really drag down my average.

33 mpg at best...

My Insight has 2500 miles on it now and I have never got more than 33 mpg. I live in Michigan and the weather has varied from 30's to -10. In the best weather I have averaged 32-33 mpg and last week when it was awful weather I averaged 29 mpg. I only use premium gasoline. I have had the car into the dealership and they keep telling me that it just doesn't have enough miles on it yet. I have tried driving so slow that people become very annoyed with me on the road, but even that hasn't helped. This is the 4th Honda I have owned and to be honest I am seriously regretting this purchase. I got way better gas mileage in my 2011 Chevrolet Cruze ECO. Beyond frustrated & disappointed. Does anyone have this problem or heard of it?

Based on these observations I would have to conclude there is something wrong with the car. It was "broken in" by around 1,000 miles, and that should only make a slight difference. Premium gas is unnecessary but should not hurt. Do you typically drive up lots of steep hills? If not, something truly wrong.

Help us help you by giving us more info on your driving. Short or long trips? Highway or city? ECO or Sport mode? Using paddles for braking? Hilly terrain? Also, I think that premium gas is just a waste of money on this car.

Tiffburg, can you please provide us some details such as:

- Your Trim level (LX, EX, Touring)
- How long are your commutes, and what percentage of them are city driving?
- What is the average speed of your commutes (25, 35, 45, 55 mph)?
- What mode do you drive in (Normal Mode, Econ Mode, Sport Mode, combination)
- Do you ever use the regen paddles, and if so, what level do you set them at (1, 2, or 3)?
- Do you have the stock tires on your Insight, or have you replaced them (and if so, with what type of tires)?
- Do you have any excess weight in your car/trunk?
- What is the average temperate outside when you drive?
- What was your last MPG rating, and how many mile did you drive before filling up your tank?
- Do you ever see your battery charge indicator level get above 50% charged, and if so, how often? If not, how high has it gotten?

I agree, the car is designed to run on regular gas. I do pay more for regular top tier gas(https://www.toptiergas.com/licensed-brands/) when I'm not near a BJs/Costco gas station.

@tiffburge I have almost similar temperature ranges as you and my average is around 42mpg. Check to make sure you have proper tire pressure. You lose 1 psi for every 10F drop.

Tiffburg, can you please provide us some details such as:

- Your Trim level (LX, EX, - Touring
- How long are your commutes, and what percentage of them are city driving? It varies. I average 65% expressway, 25% rural blacktop roads, and 10% city because I live in a very small town - one end to the other is only a couple miles at most.
- What is the average speed of your commutes (25, 35, 45, 55 mph)? expressway is 65 to 75, rural roads are 55, and city is average 25 mph.
- What mode do you drive in (Normal Mode, Econ Mode, Sport Mode, combination) Rarely use sport, only for super short on-ramps with a semi coming or something like that (less than 1%), combination of normal & econ otherwise.
- Do you ever use the regen paddles, and if so, what level do you set them at (1, 2, or 3)? No, should I?
- Do you have the stock tires on your Insight, or have you replaced them (and if so, with what type of tires)? stock
- Do you have any excess weight in your car/trunk? no, I have 2 car seats in the back seat that are very light - I'm only 129 lbs & most of the time it is just me. Kids are about 25% of the time. Combined with 3 boys, we add up to ~370 lbs. Once in awhile I get groceries... otherwise nothing beyond a laptop bag, few backpacks & yoga mat.
- What is the average temperate outside when you drive? MI varies,... alot! Made it to 50 yesterday & last week was -12. Regardless of temp, the average is always 29-33 mpg.
- What was your last MPG rating, and how many mile did you drive before filling up your tank? I'm not tracking how many miles/tank as my dealer is tracking every 1000 miles & car is set for his data... Could do it old fashioned way, but didn't see the point. You think I should?
- Do you ever see your battery charge indicator level get above 50% charged, and if so, how often? If not, how high has it gotten?
I have rarely seen it about 50%. I would say maybe 20% of the time it gets above that, but never has it been more than 3/4. I coast as much as possible, have tried to drive like a grandma to the point people get road rage, super slow acceleration or tried driving different routes. Read the entire manual cover to cover. Nothing changes that 29-33 mpg. :(

Yes! @tiffburge I'm equally frustrated.

This is my sixth Honda of my life and the first one I have regretted buying. My Insight gets 12 mpg LESS than advertised in all categories. Mileage was THE reason I bought it.

My dealer gives the same excuse. "Just drive it a little more."
This is not the car that was advertised.

Have you try giving Honda corporate a call? https://owners.honda.com/help/customer-relations
Maybe they can set up an arrangement with a local dealership to test your car's hybrid battery.


What's the manufacture date on your Insight? (Just curious if it was before the Mexican factory flood or after....)
