Society of Automotive Engineers grades One grade for cold weather and one grade for hot weather The grade for cold weather appears before the letter W The 1st grade represents dynamic viscosity in cold weather namely the ability to start the engine and to prime the oil pump and therefore to lubricate the various components quickly The lower the number the more fluid the oil The 2nd grade represents the kinematic viscosity in hot weather The higher the number the thicker the film of oil when hot which aids protection and sealing The lower the number the less friction there will be in hot weather it helps to save fuel In order to ensure immediate protection when starting the engine the choice of viscosity grade when cold is essential More fluid oil is quicker to flow when oil begins to circulate through the engine It should be selected according to the ambient temperature See the table below og A m of 40 104 35 95 30 85 g 20 z Ial Is 68 z a 3 10 a e B g 50 7 yg lg Es 5 z 23 10 14 15 5 20 4 25 13 24 240 Characteristics of GENLUB TDX 15W40 oil Performance GENLUB TDX oil is a 15W40 multigrade mineral oil which meets the following specifications ACEA E3 and API CG 4 ACEA E3 oil with superior viscosity stability suited to extended oil change intervals and severe conditions of use API CG 4 oil particularly effectiv
