After reading Suzuki ALTO's owner manual, i found the following:
According to Owner's manual 3.5 litres of Engine Oil is required but infact the capacity is 3 litres. When we add 3 litres oil, it reaches to the maximum point on dip-stick.
Suzuki recommends Engine oil 10-40 & 20-50 with SE, SF, SH and SJ grades. SE & SF grades are now obselete Now companies are making SL grade oil. this upgradation should reflect in owner's manual.
According to Owner's manual 2.7 litres of Gear Oil is required but when we try to add more than 2.3 litres, it drain out.
Picture of owner manual is as follows:
The car's picture on the manual does not tally with the latest model. Suzuki should atleast upgrade owner's manual.......if they dont have any plan to upgrade models
