okie...bought three quarts from the local dealer (i had to pay ~ $8 for shipping if i wanted to buy them online, which defies the purpose).
since i have to do an oil change (5000 miles since the last one) and check to see if there's coolant leaking in the oil (coolant getting low little by little since last year when i changed the timing belt) as well, i don't want to take my car to my usual mechanic who did the timing belt (plus water pump and all the gaskets around it)...i want another mechanic to check it, and that mechanic does not have any appointments till next week, and i'll be out of town next week...guess i have to wait for some time now
