2006 Nissan Maxima - Fuel Type?

Post by gatorgirl »

We have a customer with a '06 Maxima with a 3.5 engine who was told by the dealer to use only premium fuel in her vehicle. Is this truely recommended & if so, does anyone know why?

Mine says premium unleaded on the gauge and fuel door.

Yes, 91 octane for that engine.

Higher octane fuels are more resistant to igniting by compression rather than the spark, which allows manufacturers to increase the compression of their engines. A fuel mixture ignited by compression is called knock. Knock is bad. :cry: What occurs is the flame front of the compression induced explosion runs into the flame front of the spark induced explosion. Bang! This can cause internal damage to the engine. Sometimes it's barely audible outside the engine but inside...woo-boy!

If it says 91, use 91.

Yeah, I know...sorry about that. :oops:

When I was young I always thought that high octane fuel burned hotter and easier. I was shocked to learn that the opposite was true when I became a technician. Consequently, it really stuck in my head. :wink:

One of the guys just made the comment that they were under the impression vehicles were trying to become more fuel efficient. :?:
