The prime objective of this study is to check the friction reduction by reducing the tangential load of the piston ring. To examine this experimental study has been carried out under motored engine condition from 500 to 4000 engine speed at the step of 500 rpm at different oil temperatures ranging from 40 °C to 120 °C. 15 W40 oil was used for this study. Standard Strip down approach was followed in accessing the Friction. The whole friction measurement was split in crank train and piston group friction and was measured with base and modified piston ring pack. The modified piston ring pack was having 24% less ring tension as compared to base ring pack. The study was carried out using block, crankshaft & Piston of 100 hp, 1.5 litre, 3 cylinder engine with 92 mm stroke and 83 mm bore. In each test ring pack was tested as a part of complete piston assembly.
