Hi
Boss I have Santro GV Club 2004 in well maintained shape (water throwing soundless engine) for last 1 and a half year.
Since then;
1- I got denso original LLC coolant in my radiator and cooling system.
2- Using Liqui Moly 10W40 Mos-2 with Leppon oil filter and change oil every 5000 Km.
3- Use mixed fuel super and hi octane on 50-50 basis.
4- Iridium Spark plugs.
5- On every 2500 km, I add Liqui Moly injector cleaner and Octane booster.
And after all this ****, still can't get 14-15/km per liter average. Can advice me how to get it there.
