Self Tunning - Khyber G-10 (Plugs, valve clearance, spark gap etc)

ZIC X5 isn't recommended. (ZIC X3 15W-40 can be used it's API SJ)
I think it has API SM rating which has low ZDDP quantity and will destroy the engine. For Suzuki G series engines API SJ or older should be used.

Summer is coming guys, and we will not feel less than 30 °C for next 6-7 months. As per my knowledge SAE 10W40 is recommended grade for cold weather as it quickly flows through engine when crank. On the other hand when engine is at operating temperature SAE 40 might hurt in summer.

Why SAE 20W50 is not in recommendation list?

[hassantahir2]

Suzuki doesn't recommends using 20W-50 oil in their engine because of some reasons.
10W-40 oil is a all rounder/season oil. You can check the viscosity and temperature charts for that.

Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. If an automotive owner's manual calls for an API SJ or SL oil, an API SM oil will provide full protection.

It's all about ZDDP the G10 engine requires higher ZDDP oil the newer oil's have lesser ZDDP in order to regulate with the latest emission standards. Using the oil with lesser ZDDP will cause the cam lobes and rockers to wear out prematurely on such engines.
I don't want to start a war on this topic again as you can search Pakwheels there are many debates on this topic already.

10W40 is suitable for summer.
Pak Suzuki uses SGO Premium and SGO Ultimate (both 10W40) in all its fleet in all weather.
Honda uses 5W30 in all weather.

Oil change done, looking for some good place for tuning in Karachi who have all necessary tools like timing gun etc. Car is now running smoothly (MashaAllah) objective is to make it fuel efficient on petrol.

Any suggestions...?

Currently giving me 8 - 9 km/L without AC in city. No black smoke, plugs are Tan in color.

[shaidbokhari]

came up to a v strange issue.
car is starting..but not idling niether on cng nor on petrol.not even taking race...it shuts down as soon as i leave ignition switch. battery is strong. fuel is sufficient. but couldnt get it.

Quick replies required.

[shaidbokhari]

if it happened on petrol, i may b thinking of faulty fuel pump, clogged jet, or slow jet issue..but in cng...no idea.

Did you check ignition system. For me it seems to be current drops somewhere.

Check plugs, plug wires and ignition system thoroughly.

Quick tip: Put fuel pipe coming from tank to carburetor inlet directly (make sure petrol is coming) it will bypass petrol solenoid (if using mechanical type fuel pump), then try to start. Some times CNG switch is the culprit, it won't allow car to start on petrol or CNG

[shaidbokhari]

already checked plugs nd wires. didt felt any problem. fuel nd cng both solenoids cant stop working at a time. 1/10000th chance. direct fuel is also checked. same result. trying to start. starts for 1-2 second only. exactly 1-2 seconds nd off. no idling..not taking race.....

[car.need.care]

No its the controller switch in you dash which failed to operate these solenoids.

But well you already did the home work, lets wait for experts openion.

[shaidbokhari]

experts???? subha barish hai

@hassantahir2, @shaidbokhari, @speedster_101, @tucknoloji

Anybody know correct engine oil capacity of our beloved Khyber, I just recently pour 3.5l oil in it and dipstick shows 2-3mm above the full mark. Did I pour access oil in it? Because according to @smijaz, over filling is more dangerous than under filling.

If this is the case, how can I get access oil out, is there any way other than drain bolt?

[hassantahir2]

It's 3.5 liter with oil filter change.
But if mechanic haven't drained the previous oil completely then this happens.
Some service stations have the facility to suck the oil from top of the engine by some method.....

[shaidbokhari]

3.5 ltr always.

[car.need.care]

Oil was completely drained by mechanic in front of me. Oil filter also change...

May be it was because I checked oil when car was sitting from 3 - 4 days and all oil was in its pan. I will also check after starting engine for 2 - 3 min. Also need to check ground level.

[hassantahir2]

The method you used is correct to check the oil level i guess so...
Ground level plays a good role in this.

[speedster_101]

My Khyber gets filled in 3.25L engine oil with new oil filter.
At workshop, I ask the mechanic to fill 3L oil, I pour the remaining oil at home after checking the level because if the level is a bit low, it can be raised by adding oil but if the level is high, there is no solution other than draining the whole oil.

Today went to a mechanic for tuning. I ask him did you have timing gun? He replyed,

"Kon si gari hai"

Me: Khyber

"Bhai is gari main nahi lagti timing light"

Me: Bhai timing set karwani hai wo timing light.

"Yar wo to automatic gari main hoti hai, is main nahi hoti"

Me: Without wasting any time said, Ok Allah Hafiz.
