And built engines dont always have as tight of tolerances so you lose oil via blowby and such. Coming from high mileage or built engines has me wary of high miles between changes. Just the tuner side of me. Id rathe be safe than sorry I guess. On the other hand dont you void your warranty if you cant prove youve been following manufacturers directions?
As far as how many L or qts an engine needs does matter. less oil means faster breakdown so the galant you have which takes double the amount of oil should get twice the amount of oil life. On the other hand your 4 cylinder in the heavy galant probably has to work much harder to achieve the same results reducing oil life as well.
Basically what Im saying is the manufacturers of the oils say 20k on an average size engine which is about 5 qts of oil. If you have, say, 2.5 then essentially that 20k should be cut in half.
Not true, Mirage's 3 cyl, that is why it needs less oil. You cannot double the amount of oil to put in your car. Makes the car works much harder.
And it really said on Mitsubishi's service manual to refresh the oil in Galant and Mirage once every 20k
