Ive got a 95gxe and Ive noticed that when you smash the accelerator, that it knocks once, and if you gradually get up to speed, its fine. Anyone else have this? Seems to go away with higher octane gas, but Ive never heard of anyone else having this problem. I used to run 87 and it was there every time I got on it, I went 93 for a week and it almost completly disappeared, but I can afford 93 every week. Lol, any help?

 

What the hell? Me you Never use 87 Octane gasoline on a Maxima when you going to get on the gas. It's bad for the engine! Look at the fuel filler door, and read what it says. What you hearing is detonation or pre-ignition, If you have to use 87 gas then take it easy.

 

I didnt know that! I bought the car off my dad like 2 months ago! I havent put 87 in it for like 3 weeks now, I ran like 4 tanks of 87 threw it though..oh man Im so paranoid now..

 

in the future.. run premium man.. premium.

 

I will start...ty

 

pistons knocking? WTF, if your pistons were hitting anything then you wouldn't be driving the car. The compression in your cylinders would be so messed up...
