For "true" accurate mileage distance readings, travel an interstate highway for 10 miles while setting the trip meter at the start
I like your idea. How were you able to test the "true" mileage vs the odometer? Did you use a GPS, Mile markers...?
For what it is worth, I just filled my second tank almost all city driving (170 miles city, 10 miles of highway), and I averaged 29.9...the computer estimated 30.1. The gallons used on the computer was exactly what I put in the tank...so I guess the rest is just rounding.
Happy Thanksgiving to All in the Forum!

That's a huge variance for an odometer..... are you riding on the stock size tires? Speedometer variances are common, but odometers are usually within 1%..
I'd be really ticked if my car read 51,500 miles, when I'd only driven 50,000.

I use mile markers not GPS, don't have one at this time.
On my many trips to Colorado from GA, I often check the odometer for a 100 mile run.

Forgot to mention that a Computer Trip indicated 30.1 vs an actual 29.9 is what I'd call "accurate, enough anyway.

I do run stock diameter tires, yet take into consideration that the true dia when new vs nearly worn out may be substantial especially with large SUV/Pu tires.
In the past dealers offered speedometer "pinion gears" of different sizes to correct speedo/odometer errors.
Even in the days of the 700R4 with the electronic speedo, the gear sets were available, as in the case of my "91 Caprice.
As I understand it, some vehicles must be "calibrated" via a plug-in laptop module to correct speedo errors, as in pickup trucks with non-standard tires. These can cause in addition to ECM confusion, Braking Problems, besides speedo errors

Yeah... old Ford Econlines had a plastic odometer gear.... if you were running off, you just changed from 16 grooves to 17.... (or something like that)..
Most odometers I've had have been dead on.... mile markers, gps, whatever..... The speedometers and on-board mileage computers are another matter...
#86 of 136 speedo gears / cruze control steering wheel

(new edmunds forum idea: name a random car part and i'll have a specific story about it.)
there were two speedo gears on the pre-electronic-dashboard cars and they had to be matched. one gear at speedo head and one in/on transmission.
in an ongoing zeries of Z28s, my 89 iroc (5 manual gears, 2 catalytic converters) arrived from factory with mismatched gears such that speedo registered nearly 1.7x actual speed.
it took months to fix. GM shop tried 3 times and randomized the speedo ratio each time.
they couldn't get it right - kept ordering/installing the wrong gear.
in the end, the GM shop sent the car to local speedshop which certified cop car speedos with custom speedo gears, which they did for my 'z' . Also GM extended the warranty by 2k odometer miles.
along the way i learned to know my speed via rpm/gear/SOTP as well as learning to divide by 1.7 all the more more quickly. a state police officer helped provide incentive for such education and also provided a genuine belly-laugh and a citation for 70 in a 55 when i told him of the broken factory speedo and pointed at the stack of GM paperwork about it.
the chevy cruze surely has no speedo gears whatsoever. :|
but apparently does have a steering wheel & electric steering mechanism, also with way fewer gears than a 1980s steering wheel/rack.
previously someone had mentioned/theorized that one could swap an LTZ/whatever steering wheel onto an LS to provide CRUISE-CONTROL with no other mods required. anyone tried this or got any more info on it?

What model has dual pipes, I can't find it on here?

i don't think any cruze has dual pipes - nor speedo gears.
(previous post went on about speedo gears from a 1989 GM car with dual cats, so probably didn't belong in a cruze forum at all!)

i think the cruze LTZ model might have dual pipes,not sure though.
