Changan OSHAN X7 Fanclub / Owners Discussion Thread

[pwuser167550015690]

Oshan as a brand was discontinued but the X7 was transferred to the main Changan brand. It's not going to receive any updates though or a new generation.

They have stopped updating X7 in china, and its in its final model year now, CS75 replaces X7.

Where did you read that?

[pwuser167550015690]

Oshan brand was discontinued in 2024 so they renamed this to Changan X7.

This year, they've renamed it once again to Changan CS75 Pro for certain export markets to align it with the CS75 lineup. CS75 Plus is the higher end, while CS75 Pro is the lower end.

It is otherwise pretty much the same car and is still being produced.

Seems like they’ll do everything apart from adding some much needed essential features to it.

Has just basic adaptive cruise, no blind spot monitor, no CarPlay and Android auto, no 3rd row AC vents.

My Oshan X7 music is set to shuffle by default......... whats the remedy

anyone here facing the bad fuel average around 11-12L/100km showing on ODO, i have oshan X7 comfort for my home car usage mostly for my kids schools drop/pickup and only driven by my driver.
Bought brand new back in 2023 at tht time fuel average were great, since last year 2024 November my driver been complaining of bad fuel average and i noticed on full tank its hardly doing 350-360km wheras it used to do 440-450km. It has been on routinely service at the Changan dealership since brand new.

i noticed on full tank its hardly doing 350-360km

Thats like 6.3 km/l! LC who??

Taking it to dealership is your best bet.

Make it your daily for a full tank and calculate fuel economy.

Year? mileage?

Gilgit and Hunza trip from Islamabad with a Pentair roof rack..... increases space alot ....5 adults and 3 kids under 10 travelled and the journey was comfortable and fuel efficient ..auto hold and HSA are very useful feature while travelling up and down babusar

[mgalaxy3]

@abdullah1913 what fuel average did you get and over how many kms ?

Plus cost of the rack ?

[salik990]

bought brand new back in November 2023 and mileage is around 19k km, i have sent to dealership multiple times and they think its fine as its mostly driven inside DHA which is like short trip of 10-15km.

[mgalaxy3]

@salik990 I think most owners vastly exaggerate their fuel average. In local driving conditions specially stop n go traffic I doubt it crosses 7.5km/L.

Yours is even more terrible.. any others in your circle what average are they getting in local?

[abdullah1913]

Well I calculated the fuel average and it's around 9.5 Km/L...traffic was bumper to bumper all the way in including on steep hilly terrains and Babusar incline.. moreover Mahindari bridge had a traffic jam for like 3/4 hrs and vehicle AC stayed ON throughout the journey due to hot weather....

i dont drive Oshan X7, its my home car driven only by driver since 2023. Since last 8 months the fuel average has dropped significantly as i got to know from my driver complaining of low fuel average. It used to do 440-460km on full tank but now its hardly doing 320-330km. i have sent to two different dealership multples time both dealers said its completely fine as they didnt find any fault in the engine. Dealership think my driver driving habit is hurting the fuel average but my driver is driving it since it was brand new from Nov 2023 till 2024 Dec the fuel average was fine, what could be the reason from last 6 months?

[mgalaxy3]

Can’t say. Could be excessive idling with engine on (that really hurts average). Or bad fuel. This much drop is usually from driving habits or something clogged in the system.

Try a fuel system cleaner additive from a good company like Regane .. I doubt it will help significantly but doesn’t hurt.

Does it travel on highway? Modern Turbo GDI engines carbon up pretty quickly if driven consistently in city over short trips. Its almost a necessity nowadays to drive them on long distances at highway speeds once in a while. Also, if it has been running on high octane for long then that’s also a culprit for bad mileage over time.

[kameetaha]

TL;DR It needs Italian tune up.

[tech_wiz]

Italian tune up is a double edged sword especially for modern T-GDI engines. In theory it can work (specially for older engines), but for new ones, not necessarily (high revs can even have an opposite effect, i.e. increase carbon deposits due to more blow by because of lower tension in piston rings of newer T-GDI cars).

The key is to get the engine hot enough on a constant load for a time long enough for carbon deposits to break down. How hot enough? Varies from engine to engine. How long enough? Jury is still out on that one. Newer ILSAC GF6 oils help in preventing carbon deposits from building up but won't break down existing deposits. Here's a complete video on the subject.
