Before, it was only octane 95 gas available, now we have two choices of course 91 is cheaper and I can save significant money. My worry is that may it can harm my engine.

What country do you live in? In the USA the altima was introduced July 1992 as a 1993 Stanza/Altima. 1991 Skyline GTS-R is that what were talking about? Detonation will burn valves and pistons. Spark Knock, Ping all the same thing. You will not save any real money use the good stuff and have your car checked over really well. Sounds like your country is going thru changes in fuel formulation that may make your older car run bad.

I get that question a lot. Your car and mine are designed for the good fuel. If you drive like grandmom. Lower octane might be fine. But it says premium fuel reccomended on the gas door doesn't it? Try this test measure the next two tanks of regular gas milage is the key. You'll see low octane does not allow the fuel system and spark control run for maxium power. So you will push just a little more on the accelerator. Premium fuel however is what the 9.0 to 1 compression engine was designed for and you might find 3 more miles to a gallon running it. Thus saving money over the twenty gallon tank. Owners manual section 9 page 2 says (91 octane) and 20 gallons 60 more miles or 8 dollars might make up the difference in price. 20 cents x 20 gallons or just four dollars more per tank And you thought you were saving big money. And costing mileage lost $4.00

You do not have to use 91 octane in this car.... That's just the reccomended.... It will run fine with 87....
