this engine came from mid 80s to early 2000. And performance of this engine is really outstanding.
but this engine came with 2~3 different types of fuel supplies.
one is called "Piston wala Carruburator".
one is called "Without piston Carruburator"
i don't know what we call to 3rd one.
i had lancer with Piston wala carruburator. This is perhaps most notorious for drinking fuel. But after putting the fan in auto mode and installation of PCV, and replacing the breather pipes, and using delo gold 15w-40 diesel engine oil (in petrol engine) it was giving me 10 km/L within city with & without AC.
At long route, no one will believe but it gave me 15~17 km/l average.
i still remember the goods time i spend with my 91 lancer with 4G13 engine. I drove it almost everywhere in punjab including Chakwal and Kallar Kahaar, and once in Murree+muzzaffarabad with family.
