Hello, i change my engine oil today at a valvoline instant oil change center. I have a manual transmission and 46000 miles. I was told that the transmission oil must be changed every 30k miles. i thought manual cars would go a lot longer. They also said I have to change the differential oil every 15k miles. Are this numbers correct? would it be ok to change the differential and transmission oil at a valvoline instant oil change or should I go to the subaru dealership for this? Any one with high miles has experence with this?
