I got my 2003 Honda Accord about a month ago and have put about 1000km on it so far. Eventually when I reach the 8000 km first oil change, I want to put a 10w-40 synthetic oil instead of the 5w-20 recommended in the manual. Does anyone know if I will notice any differences as far as the car performance goes or if there will be any problems that can happen if I do this?
Thanks!
