Morbid MPG During Break-In??? (1 Viewer)

Holy gas guzzling cruisers Batman!

I am hoping that the 10 mpg combined that I just calculated is due to me still being under 800 miles and there being more - um friction?

I did put K02's on. Even still - near single digits seems crazy low no?

You should get around 17-19 highway...around 13 around town. If you are doing a lot of stop and go only? 10 is not unheard of...

Question for you:
-What are you doing as your version of "break-in?"

What was your break-in process? You didn't run the highway at a constant speed did you?

I was getting just over 18 mpg highway during my first 2k or so miles. When I put the roof rack on it dropped to around 17. Most of my miles are highway, but I'm averaging around 16.5 mpg. Just under 5k miles on the vehicle now. I attribute the good mileage to the Jowett @bjowett oil cap!

Nothing in particular. Just been driving it around my area. Stop lights. Varying speed limits. Why? Should I be flooring it more often or something?

No you're doing the right thing, varying speeds, stop and go driving is the absolute best for break in.

I mentioned the highway thing because highway driving at constant low RPMs makes it harder for the rings to wear into the cylinder walls and could lead to glazing. It's harder for that to happen much these days, I'm an old engine builder so I pops in my head.

Keep doing your thing, I'd do an oils change at 1,000 miles, be amazed at the amount of metal shavings loaded in the filter and oil.

Keep doing your thing, gas motors are never efficient till they get a few thousand miles on them. Now if you are at 3,000 miles and getting 10 mpg, let us know. Something isn't right.

On second thought, please check the oil level when the motor is dead cold.

How did you calculate your mileage? If your KO2's are not stock circumfrence, your odometer is incorrect. You should be correcting your odo then dividing that by gas pump volume. Anything else could be wildly inaccurate.

My driving route/times for my 2017 LC has been pretty consistent over the 3K miles it has accumulated so far. All stock I started out averaging about 12.5MPG that slowly climbed to about 15.4. I yanked the back seats and installed an ARB drawer system, then put on a set of Trail Tailor step sliders. In my case that's like driving around with an extra two wives in the truck (excepting the drawers/sliders don't complain about how I negotiate traffic). Since the parts additions I've seen a loss of about 0.2MPG (still on OEM tires). But not scientific at all and the mileage loss could be just as easily attributed to more frequent stop and go due to summer tourists out on Highway A1A.

FWIW: I'm at about 13-14mpg hwy, gps calculated, 7200# of armored, 35'ed, camping gear filled, Land Cruiser.

My experience with my 09 LX as well. IF you are doing a lot of stop and go (ie. city driving with stop signs every few hundred feet or daily heavy stop/go rush hour city traffic), I wouldn't be surprised at 10mpg. These things are a pig on gas in the city

Does your mileage go up if it's not driven right after the Huracan?

 

[jomelo]

I had/have the same issue. I bought a 2014 new and did not really recall any poor MPG during the break-in. However, my 2017 was getting considerably worse mileage than the 2014. This is driving same places and with the same KO2 setup. The 2017 is completely stock - with exception of the KO2's - and I'm lucky to get 16 on the highway and this is driving 75. The 2014 was around 18 in similar circumstances. Same difference for in town driving.

K02s definitely knocked a couple mpg off my average. I'm getting 14 mpg overall:

The best I got on the highway was 19.9 mpg, but that was before the K02s. My most recent highway trip was 17 mpg.

I have a 2017 that I bought new with 5 miles on odometer; now have just over 6000 miles. Overall average has been 15.7 mpg which has been a good mix of city/hwy. Only mod is rims with 275/55/20 Nitto Terra Grappler tires. Initial mpg and mileage range was lower but has been steadily climbing, but never saw 10 mpg, even in city driving. Typical around town was 13-14 mpg. Best I've seen on hwy was ~18 mpg at 70-75mph on a beach run loaded with 4 people, an overweight black lab and a cargo hitch carrier. I will also say that going from a 2007 to a 2017 has been a night and day experience. It feels like this 200 was built right out of a solid piece of granite. Don't get me wrong, I liked my 07, but damn this 200 is a freakin beast.

50 miles on my wife's so far, 8.8 mpg on dash display, all city. I will hand calc next tank and see what I get

When I was buying my 200, I test drove a number of brand, brand new 200s with 1 mile on the odo. They were guzzling gas in the 7-10mpg range. I wonder if dealer resets the air fuel ratio after certain amount of mileage. When they are shipped from Japan they have the minimum amount of gas put in that barely got us few blocks to nearest gas station. The car was covered with plastic wraps everywhere and felt extra, extra dry in the heat.

My truck is at 65k.

My low point was 6.5 mpg in the city during the winter. That's real city - I live on the edge of Chicago, so you can't drive 500' without hitting a stop sign or a traffic light, lots of short trips (i.e. the grocery store is <3 blocks from my house), and some idling while waiting for the kids. Most winter city driving is in the 7.5-8.5 range though.

Normal city driving during the summer is 9-10 for me. I might see 11 if we make some trips to nearby suburbs. All highway in the summer was 17mpg (that's resetting at a rest area then doing nothing but highway) on Bridgestone Duelers though I'm getting closer to 15-16 with larger, heavier Nitto AT tires (computer says 15 but speedo is about 5% off).

FWIW I've gotten right around 12 mpg (adjusted) on this tank, which was 1/2 highway and again with bigger A/T tires.

To add to the data- hand calculated, from mile 207 to 12k miles is average of 15.62 - a graph of the data shows flat trend. Best tank was 19.4 and worst tank was 12.17

I do lots of less then interstate road trips and live in the mountains.

This rig has yet to hit the trail.
