2.5 quarters
yes all the dx lx and es proteges have the same engine. atleast that year does
the haynes book says take it to a mechanic
10w30
3.5 0r 3.7 qts i would start with 3.5
5w20
Cost for me was 120, but that is the high end. One thing to be sure of is to take it to a Mazda garage. Mazda protege's have been known to hate non-mazda belts and cause high pitched squealing after replacement.
For a 2002 Mazda Protege 5, the recommended oil is a 10w 30. 5w30 is recommended in temps below 30 degrees f.
Take it out and put in a new one.......
dextron mercron
just take it to the top it has and over fill bottel
3.5 quarts of oil
Mazda dx what? Protege, 626, B-truck?? Protege capacity would be 2.83 quarts or 2.68 liters. Mazda 626 manual trans would take 2.9 quarts or 2.7 liters.
