Hello,i recently bought 1979 Ford Mustang with 302 Windsor engine and C4 automatic transmission and i want to change engine and transimission oil but i dont know which oil is recommended,so i am asking your for help with this...thanks
thanks for reply,about the engine oil - 10w30 is ok but what about api classification?and tranny oil - i was thinking about dextron III - are you 100% sure about this oil (i dont meant it bad its just question because rebuild of transmission is quite expensive here in czech republic so i wanna be 100% sure that im using right oil to prevent damage of transmission
i was googling and i found out that dextron and mercon is the same oil ,but one thing is little worrying me - i remembered that on the tranny dipstick is written something like use ESW-M2C33-F TYPE F OIL - so is type f oil some old oil which is not used today ?and i've got one more question about engine - sometimes the ENGINE warning lamp lights up during the ride but everything seems to be normal . engine runs great,it has good temperature and there is a enough oil in the engine - what can cause this lamp lights up?
