Has anyone put 87 in there max? My car is jerky, shakes, and has lower rpm (650 ish) at idle and doesnt want to move. Not sure if this is a fuel issue or a something else.

 

If you look at your gas tank door where the gas cap is, it says for better performance use premium gasoline. Maxima engine is designed for higher grade gas, not the cheap gas(87).... you should use 91-93 ocatne gas. Your engine is probably knocking and pinging at this point. You can hear it from out side.

 

93+ is IDEAL(maybe a bit low) for 10.5:1 compression.

 

if you like your car just go premium its really not that much more if i can afford it. Does it make a diffrence? it is suppose to prevent predetination. Just use Premium if it helps you sleep at night i do.

 

Just use premium, idk why people think its so much more. At most it's 10 Cents more per gallon (here anyways) I usuallly put in about 8-10 gallons when I go to the gas station. So it's less then a dollar to have you car run how its supposed to.

Considering I have pay $160 a MONTH for insurance, $1 more for gas isnt alot.

 

A properly tuned Maxima shouldn't experience these problems on 87 octane gas. There are other issues at play here.

Are you throwing a CEL?

 

I know it goes against the manual but up here in Canada, 91 octane is 10 cents more a litre = 40 cents a gallon = $5.00+ a tank. Since my driving is mainly hiway, I dont see a real advantage or requirement for the hi octane fuel, my car runs great on the lo test, no pinging or hesitation and it is at 171,000 km, 99 gle.

 

When I first got my max, I used 87 and would always get a CEL for 02 sensors. When I started using 93 all the time I never got the 02 CEL anymore.

 

87 octane gas is FINE for our cars. 95% of maxima owners use it with ZERO problems. The problems everyone on this board has with 87 is one of the two:

1) they're **** and will think any problem they have is related to 87.
2) the get a bad batch of gas (excess water) and blame it on the octane.

Run a can of dry gas through your tank and I bet you your problems will be solved even still running 87.

 

I bought the car a few moths ago and i've always used 91+ octane, i just started it and got the roughness like it was de-tuned or retarded in timing. When the car acyed like this i just assumed it was a low octane issue, possibly tanks were mixed up @ Sam's club here..not sure. Today the check engine light did come on. Just did a tune up 4k miles ago as well as changing all fluids. Still trouble shooting.

 

seems to be a bigger issue than fuel..still lokking into it

 

I would never use 87, but if you are trying to save a buck on everyday driving, at least use some injector cleaner regularly with that 87 cause the octane is not strong enough to keep your injectors from clogging. Stick to 93+ though...the extra change per fill-up is more than worth it.

 

mm..i use 89...is that better or still sux? The 91 around here costs 2.27/gallon

 

The more expensive gas gets, the less significant $0.10/gallon is. There's not that much of a difference between paying $1.80 and $1.90 per gallon.

If you get better mileage out of the better gas, it's partly paying for itself.

Good Luck!

 

again, I really wish everyone would read the following article before shooting BS out their cracks:

Read it from top to bottom and THEN you can post about what you think our engines should run on.
