Sirs, joined the numerous Isuzu Hilander owners,mine is with me almost 15 years... Still in pretty good shape, I am just curious,recently I had my Hilander serviced for chane oil using Valvoline all fleet..used about 3.8 to almost 4 liters as indicated on the rankings of the 5 liter container... Had an oil reading and came out over maximum... Had the reading in the morning when the engine is cold,do I need to drain some oil or just leave it be... How much is the recommended oil in liters for 2.5 4JA1 engine... Thanks
