Correct, 87 is what is recommended, so it's penny wise, dollar wise to use 87. I agree that if your engine requires premium, then you should use premium, but this is not the case with the Altima. You should probably know this by now if you have an Altima, or at least have looked it up before making all those comments. I've had high compression engines and turbos that needed the higher octane, and on those all your responses are correct. I got better milage and avoided pinging by using the premium fuel on those engines. On cars needing regular, I see no no advantage at all. I had a boss that insisted on premium for the company car, so that's what we used for years. Later when gas prices went up, we switched to 87, no difference at all. I've actually seen a much bigger difference between brands of fuel. On a very poorly maintained company car, it ran fine on Shell or Chevron, but when we filled up at a Valero, the engine died every time we came to a stop and sputtered when trying to take off. Granted the spark plugs, cap, and rotor had about 100k on them and they were 30k plugs. I saw the plugs when they came out, amazing the car ran at all. With new plugs, it ran fine on the same tank of cheap gas, but I'd bet the MPG suffered some. We didn't buy any more gas there to find out.
