My friend has a 2001 Honda Accord LE, I4 engine. He has been using 10W-30, I guess because that's what most people use...I don't know.
Anyway, recently, he (actually, I discovered for him) found out that his car, according to the car manual, suppose to take 10W-20.
The car was bought new, and currently has about 58,000 miles on it.
What are the possible bad effects for this? According to him, the car runs smoothly.
