Hey everybody. Just got an 02 SE with 68K miles on it. THe main question I want to address is even though I dont know what kind of oil th previous owner used but would it be safe right now to convert to synthetic oil for the rest of the time I have the car? I use synthetic for all my cars and would also want to on this maxima. If I do, would it damage the oil pump which is probably used to the regular oil (I'm assuming the previous owner used it)? Also what other things should I take a look at? I'm thinking replacing spark plugs, replace the air filter, and clean out the spark plug coils. Any inputs would be appreciated. Thank you.
