Yes friends its 1500 CC ,Automatic. And i always keep the rpm under 2000 when accelarating ...

Dear Friends, I have Nissan Presea (1999) Refina ( R11) .I bought it last January and found that the car was having Valve oil seal leakeage. I did full engine overall with Nisssan genuine parts, ( Includes Piston rings etc). After that i did EFI cleaning ( Not ultrasonic ) and after few days I used wurth EFI fuel system cleaner . MY PROBLEM is the car does not do atleaset 6.5 - 7 km/L in colombo with minor traffic. I usually go in the morining and come back in the evening which covers abt 14 Km Up n down. Hoever i recently had a repair in the alternator ( replaces the coil) and the mechanic said that the original IC has burnt so the previous owner has put a 12V stabilizer from out side to subsitute the original IC in the alternator . Does thiis can have an impact on fuel milaage? or what is wrong with my car....! plase help...! (The fuel millage was same even after the alternator repair)
