What is normal reduced level of oil which is considered abnormal. Should a normal engine decreases a bit oil below that mark?
yes a bit even a quarter 1/4 in lets say 3000 kms is normal. Every engine in the world consumes oil.... some more some less depending on the conditions.
My car reduces oil just below the upper mark just above the mid between lower and upper limit. Is normal? And i want to switch to zic1040w. Will it be a good choice. Currently I'm using honda SM 10w30. Thanks.
