Hey guys! New to chevy and the cruze world, pretty familiar with diesels in general though. I've had a couple mechanical injection vw's and most recently rebuilt a vw 1.9l mechanical injection engine and swapped it into my samurai. This is my first computer controlled direct injection engine and I'm pretty happy with it so far. Its not the exact car I wanted (white, hatch, diesel with mt with brown leather) but its one of the 3 manual diesels available in the province. On Friday I grabbed a 2017 cruze diesel lt with the 6 speed manual. Its the silver ice metallic with black leather interior. Until about month ago I had no idea chevy had a diesel sedan and went with it over vw mainly because of the 0% financing and that vw doesn't have any new tdi's.

So far I love the car, the electronic throttle takes a bit of getting used to and the clutch has a bit of a different feel to it but the power and economy it makes are amazing for what it is. It has way more power and is way quieter then the old mechanical vw's. The one I just built for my samurai has a 4bt turbo and a performance injection pump and its probably making around the same power but its nowhere near as refined. Its loud and shakes like crazy. I'm not too impressed with the transmission, it rides alright but I feel the gearing (mainly 6th) is off and feel like the shift light is constantly blinking at me. I've got just under 1000km on it and I filled up for the first time the other day. I got 850km to 44l which puts it just under 5.2l/100km and means the dash display was right on with its estimate. 5.2l is about 45mpg which is pretty good as I had a decent mix of city and highway driving. I'm just curious what kind of mpg everyone is seeing per tank in the real world? I'm also curious how many km's it takes for the engine to break in and if there would be any noticeable economy increase at that point?

Anyways here's my cruze the first night I got it

and here is a pic from the dealer

No real plans to modify it much. Maybe upgrade the headlights to HID's, get the dealer to install some fogs, and when the warranty runs out I'll delete all the emissions crap and throw a tune on it. Would love it if someone brings a plug in piggyback ecu to market that wouldn't effect the warranty!

I'm averaging better than 55 MPG overall. I raised my best 25-mile average to 72.5 when the weather got cool earlier this month. Very happy with the fuel economy.

Just got mine on Saturday. It's a '17 premier hatch RS. So far I'm averaging 31-32mpg, with 400ish miles on it. I have a 100 mile daily commute (round trip), almost all of which is highway.

I am around 17-18 mpg in my 2013 Cruze. That Corn life. E85 kills your gas mileage, but I also pay less than $2/Gallon typically.

That's crazy John. No way mine can get anywhere near that right now unless its on perfectly flat ground. Im 7/8 through my 2nd tank but it seems my mileage has really taken a dump in the last 100km or so. Went from 5.2l/100km to 6l/100km average with not much change in driving style or conditions. How many miles are on your car?

My 2013 gasoline cruze that I bought new has +/- 21k on it now with a lifetime average of 37.7mpg so far. I might add this is mostly a highway driven car so to speak and I don't have a lead foot.

14 eco 6spd manual 1.4t averaging 50+mpg on my normal commute. Freeway driving at 70 mph comes in at about 45mpg(with ac on wife in car). I never take freeway if I don't have to. Best tank 59.1. Worst 37.8 I think( several snow storms) goal is to break 60 mpg.

I have 16,000 miles on mine now. My commute is about 52 miles each way and mostly follows a river, so it's relatively the same altitude, but I do have to summit a good-sized hill on both ends. Speed limits are 55-60 MPH for the majority of the trip, which helps. I almost always see 60-something on my 25-mile average each way during my commute.

I think I could average 70MPG on a whole tank if I had enough flat ground. I'm hoping to see 800 miles on a single tank at some point. My last 60+ MPG tank was teasing 800 miles (trip odometer + range to empty) the whole way, but circumstances didn't align to let me test it.

My lifetime average is 43.9 over 40300 miles. This past six months have been 1/2 of those miles and I average about 46 mpg. I don't drive like grandma hardly ever, normal on freeway is at least 75. So far couldn't really be happier with the car and its efficiency. Ready for diesel prices to moderate but may not happen for awhile.

Did it take a while for your engine to brake in before reaching those numbers? My mileage isn't bad by any means but its not really close to what you guys are getting. Sure with cruze control on flat ground I can get them but there's no way I can average that for an entire tank yet. I doubt I'm going to even hit 800km (500 miles) this tank, 800 miles just sounds impossible. Definitely have more stop and go traffic and more spirited driving this tank vs my first but its going to be interesting to see if it gets much better.

Mine was good from the start. I think fuel economy is improving as the engine breaks in more, but my first 60MPG tank was at 4000 miles and I've never had a tank lower than 52MPG, which is the EPA highway estimate.

My driving style varies a lot. Some tanks I intentionally drive for economy, but after driving so conscientiously and carefully for a whole week and 700 miles, it gets old and I just set the cruise or do some more spirited driving. The cool thing is that even when pushing for a high mileage number, it's pretty forgiving of a few heavy-footed moments.

One thing I have noticed this month is that it really likes temperatures in the 50s and 60s. I got to 60MPG on my 50-mile average this morning and wasn't even trying. It's in the low 60s this morning.

Yeah that's insane. Do you do mostly highway driving on flat land? Just filled my 2nd tank only got 734km and the dash showed 40mpg. The app I use to track fuel shows it as 37.5mpg but part of that reading is I don't think I fully filled it the first time. Didn't really think about how much diesel foams up when filling. This time I started squeezing the handle really slowly for the last few litres. Is yours manual or automatic? Mines manual and I struggle to hit the shift light as it seems like it's too little rpm for the engine especially if there is any hills involved. The light comes on at like 1700rpm.

my 2015 1.4l 6 speed 1LT from just over 1000 miles trip is at 36.8MPG, put a k&n intake kit on around 300-500 miles ago and it seems to just keep going up as long as im not using the lead foot

how are these guys getting 50+ MPG???

advanced eco tune?

my car is bone stock except for the k&n

EDIT: Whoops clicked on this from one of the main pages didnt notice till now this was in the diesel subsection LOL

Most of my commute is 55-60 MPH on rural highway. Because of where I live, that's most of my driving no matter where I go. It's mostly gently rolling terrain, but there are two or three grades that are uphill for a mile or more.

My experience with the fuel computer is that it's pessimistic. My calculated MPG is usually higher by anything from a little to a lot.

I do take time to fill it to the top of the neck. Part of my reason for going with this diesel is that I only have to fill it once a week to drive the 600-700 miles I cover ever week. I'm OK standing at the pump an extra 3 or 4 minutes to get it good and full.

If I follow the shift indicator, it drops my RPMs to around 1500. I don't pay much attention to the shift indicator, but I've noted that the computer doesn't think it's lugging the engine too much at 1200-1500 RPM. It is a diesel.

Yeah I try and ignore it but for some reason whenever it pops up and I catch it out of the bottom of my eye I have a thought "oh crap better shift!". I just find it funny they made all the gears so small. 5th should be as big as 6th and 6th should be like 1500 or 1600rpm at 60mph. Cruzing on the highway at 60 already puts you above the computers shift point.

Must be the fact you're driving all highway. I do roughly 70% highway driving but some of that is in high traffic. I guess my mileage is in line with epa esitmates.

I did the same thing due to the fact that several other gassers already chimed in. I'm 50+ without a tune anyways. Just stay off the freeway. Rural highways(55mph) are how I manage 50s that and using torque app. I keep it out of boost and under 75% load. Seems to work well since I lost somewhere between 3-5 mpg going with non LRR replacement tires. 50$ used set of tires 3/4 tread can't go wrong.
