Change piston rings.
Beshak ALLAH he sy hy sub waqt sy pehly nahin zarorat sy zada nahin.
petrol and CNG
total quartz cng oil
engine sound good and when i buy the car engine was good no smoke !
service intervals sargodha to lahore in months 3 times and form shop to home in city sargodha in months km 2800
Rpm 4 to 5
Yep I think mr Osama is correct. Piston rings are weak. Is there any other problem, I mean heating up or sounds? Just fill up the radiator to full n check If there's any oil film formed over water. Check for knocks (sound) when u rev up.
RPM seems high and we will attempt to reduce, but first lets get the basics in order.
Can u pls post a daytime photo of the engine ?
Q1. Do check the hose pipe going from the crank-case vent to the top of the combustion chamber... DOES IT HAVE any oil on it (it can be very clean oil and not necessarily black color oil) ?
And just take a close look on the engine, is there any oil spot any where at all ?
note: it is possible that oil drips, then covered with dirt (b/c you are frequently driving on highway/motorway).
Q2. With your driving conditions do you clean the air filter every week or 1000 kms ?
Q3a. What color is the smoke ? Does the color change when going from low to high RPM ?
Q3b. Is there any smoke when in the morning (when engine is cold) and no accelerator pressed ?
Q4a. As @Flyhigh1 asked, is there any knocking, is the car heating up, is radiator functioning OK ?
Q4b. And is the coolant getting consumed (are you adding coolant, when and how much quantity) ?

A2. i clean the air filter every 5th day and after 500 km
A3a. smoke white color and on low rpm no smoke
A3b. in the morning no smoke comes water only
A4a. no knocking sound and not heating up only come bubbles from radiator !
A4b. not add coolant yet
First of all re tighten the cylinder head bolts,if your problem solves,then it means every thing is o.k,otherwise valve guides or valve seals need to be replaced.
Never loose hope in life,every step gives u something.
use stp oil additive it thickens engine oil and stops it from burning. if using this stops the reduction of oil then your problem is obviously weak rings
haters gonna hate, potatoes gonna potate
please proceed to a workshop or mechanic who owns a compression tester - after that you will certainly know whats wrong.
If you used to drive your car with the needle on C and never ever serviced the PCV - for sure the oil scraper rings must be jammed with sludge

please do this ASAP. As you said it is White colored smoke, it is possible there is accumulated moisture in the engine that is putting stress on the engine. But much of this "amoke" is most likely an engine oil burning issue and need to do compression testing by a good mechanic.
I would also recommend using a better engine oil to maximize sealing of the Piston Rings Cylinder clearances.
If possible use the "LX fuel supplement" together with petrol over a period of few months, OR for alteast 1700 kms approx., preferably for 5000 kms or so. (Call at 0314-222-111-4 or 0314-222-111-2 for LX only).
This will help clean out the combustion chamber deposits (surely you will have a lot of such desposits).
In addition, it will also improve the Power to RPM ratio, that is, lower the RPMs requried for gear shifting.
You can do this even when using 50% times CNG and 50% times petrol. Only total time duration will increase.
Do let us know the mechanics comments after the compression testing.
The problem was valve valve guides and valve seals
ring piston and all thing is good !
thank you guy's
