I have a 2002 Nissan Altima which has over 150,000 miles on it. I noticed a lot of knocking and pinging when I hit the accelerator. This happens after the car has been on the road for maybe 15 minutes. When the car is in stop, it runs fine, only when I put my foot on the gas is when I hear those noises. Per the manual, I only put 87 octane in, should I maybe be putting a higher octane in or is there something else I can do besides taking it to a dealer. Thanks
