Dude,
For oil change dont go for any of these brands,
Caltex, shell or bla bla bla bla bla... Remember there are only two synthetic oil brands in this world of Pakistan.
1. Mobil OIL (THE OLDEST)
2. Zic A+ (i personally prefer this)
WHY ZIC A+??
Between i had a cultus back in 2003. I drove it 275000 km and used only ZIC A+ which was very rare at that time. Believe me, all these other oils are **** crap.
My car when sold was
1. Not overhauled once,
2. No rings
3. No valves no fan direct not even a change in head gasket.
4. The guy who brought it was shocked when i told him the car had originally done 275,000 because the mechanic who checked it said that the car silencer was giving water (a sign of excellent fuel combustion) (car was driven by me 45000 petrol then i converted it to cng NOT FACTORY FITTED)
5. People lie about mileages since in cultus u have a xxxxx meter which resets after 99,999
6. Recently a close friend of mine changed to synthetic ZIC A+ for his city from Shell on my advice. And if you dont trust me, give me a call 03314002910. Ill make you talk to him, he will explain you how smooth his ride became
7. HONDA GENUINE (crap genuine) OIL: manufactured in Pakistan
8. Toyota GENUINE (crap genuine) OIL: manufactured in Pakistan
9. Take these oil samples to a test lab ISO certified (you can find em in Karachi, back when caltex was quiet the hot topic before its merger, you could get the oil grade tested) and all these oils are not synthetic
10. Synthetic oil will preserve your engines' life, wear and tear+ save you on the ring part preventing your engine head from being touched
LASTLY: the gas issue. My dad is a mechanical engineer so i know this stuff well God bless him.
Who told you to run your car on gas when it didnt even do 1000. DO you know, a new engine has fresh BORES (in urdu) the area where your piston moves and NEW RINGS
You need to run it at least 2500km to get your ring and bores in proper shape. and then drain and throw all the oil since metal deposits pertain within the engine after 2500 which is not good for engine. In some cases people do it after 1000. the earlier the better.
Once your car's engine grinds the bores to the appropriate RING size, then go for CNG. and then go for setting your car's CNG.
AND LASTLY: You tampered with your car's WARRANTY by installing a CNG kit
NOT A GOOD IDEA!!!!! because if there are any manufacturing defects in cars, companies pertain to the fact that warranty is void if modification has been made to your car. So you could have hold on to your car's petrol engine for at least 2000km and then planned up your gas kit.
Now i am not scaring you. I can lead you to right people to guide you righteously if you think i may be making this up and who are the only EDUCATED car mechanics of Lahore (not those hatora mechanics), but they are a bit costlier. And if you purchased a COROLLA i guess you can spare the car some good money rather than visiting these filthy crap filled disgusted TESTING CAR mechanics who make stupid mods to mess up the car.
between u were over charged for your cng kit
Aur zamana itnaa chawal hai k 99 percent of mechanics are cheaters. i just know the remaining 1 percent who don't and trust me this is not because i may be a workshop owner who promotes my workshop (because i earn and dun have a workshop) but this is because if you go visit tommorow my list of good people,
AAP mujay dua dey do gey..:P.
