87 or 91 gas?
 

It sais to put 91 gas, but would it hurt to put 87? I know the performance will be temporarly decreased (untill i put 91) again, but not overall....right??

I think this has been discussed a couple times, but higher gas prevents knock. And my 350 knocks with anything less than 89, so I imagine the 370 is even more dependent on higher quality gas for knock prevention because o the compression ratio. Now is the question will it actually hurt your vehicle? Not in the short term, but could eventually hurt your engine.
I believe you can eventually damage your piston rings, damaging your pistons, so forth and so on.

To add to Frost's comments about possible long-term damage, if Nissan discovers that you've been putting in the cheap stuff when their manual (as well as the label on the inside of the fuel hatch) clearly states that you must use premium, kiss your warranty coverage goodbye (should you end up with a damaged piston type of problem).

But I want to take a step back and ask why you're even considering putting the cheap stuff in. Would you bring a child into the world without intending to provide for his/her nutritional needs? Or would you adopt a pet without intending to adequately feed it? Only irresponsible trailer trash does either of those things, right? So don't get a sports car if you don't intend to provide it with the fuel it needs either. Don't be the automotive equivalent of 'Octomom'!

Def put 91. Why do you want to take a chance at damaging your engine or drive with decreases HP output? I have a tendency to listen to Nissan Engineers :tup: Attachment 955

yea i used to put 91. in a g35coupe
there were those who just put in regular...and were fine.

but since i like to be "safe" a couple of extra bucks per fill wasn't that bad.

^^ ftw! Just follow the manufacturer's suggestions and you will be golden.

Right, if you can afford a $30K+ sports car, you surely have the financial stability to not concern yourself with a couple bucks more in fuel costs.

You have 2 choices...

a. 91.

b. buy a Tata Nano and use all the 87 you can find.




ps - don't forget to take your bolt size and your chips into account when choosing the fuel.

Use 91, and you won't be sorry.

:bowrofl:

Or ask your brother

Please do not skimp, when it comes to such things as cars and or its parts etc.. It's not only about looking lame or being cheap, It could also be downright dangerous.

Get only whats authorized, required and or recommended by the manufacturer.

I wouldn't put less than 91 in my tank. Also have a Maxima and ran 87 for awhile but could really tell engine was not running well and hard to start. If your goin to buy a Z figure on buying the correct gas

I say you just run water. Its cheaper.

Very well said.....I have always put nothing but 93 octane in all of my cars........it has more additives ....and is well worth the little bit of extra money !!!!
