ONCE you need to know about your new vehicle, this is the hard way of learning we people go through, but it teaches more...
IF you don't have manual, There is one way to check.
While adding engine oil, take the stick out (oil check dip stick) and clean it.
after adding 3.25 Ltrs, insert it and check if the upper whole is covered, if not add .25 more and check. Lower whole mark is dangerous level (minimum) and upper is safe. You can fill 5 Ltrs may be and it will fill whole engine above cylinders BUT dip stick is made according to level...There is not much difference in 3.5 and 3.6. for Mehran it's 3 and Khyber it's 3.5.
For gear oil, again without manual, it's try, add 2.5 and check level.
Memorizing, for one time when Pakistani mechanic had bet with Turkish foreman M-1 project. after making engine of bulldozer our mechanic had a bet that it will start on 1st self and he WON.
