Anyone using regular gas instead of the Premium thats recommended

Is it worth the extra $$ 03 GLE

Post by **AcMav** » Sat May 03, 2008 1:41 pm

Ive used regular in my I30t for years, i just recently switched to premium because my knock sensor went bad so its worth it for me to use premium instead. I've had no problems on regular fuel.

89+ seems to work best for me. Anything lower just makes my car sluggish and is bad for the knock sensor. I want to try 93, but I can only get 91 here in Cali.

I've been using regular 87 octane fuel since I've bought my 1997 Maxima and I haven't had any lack of power or problems of any kind.

Premium will make a bit more power, but regular is perfectly fine in your '03 (and really any Max without a VG under the hood).

When I first bought my 99 max in 2003, I used 87, then had 2 o2 sensors go bad on me and the mechanic told me not to use 87 anymore. I've been using 93 ever since with no problems. But now that the gas prices are about $4/gallon for 93, I'm gonna be putting in 89 every once in a while to save some dough!!!

Premium gas is roughly 20 cents more per gallon than regular unleaded. Even if we had 20 gallon tanks, putting in premium over regular unleaded would only be $4 more. Because we don't have 20 gallon tanks, it would be less than $4.

Lately though, I've decided against premium. it burns so much faster than regular, which means you get less mpg.

Weve owned an 87 Maxima, a 95 Maxima, and the 99 we have now. All 3 with regular gas. 87 got 270,xxx miles and then dad wrecked it. 95 got 180,xxx miles and dad wrecked it. The 99 has 111,xxx and still is going strong

There is a pump at the gas station by my house with 100 octane. Lord knows I've been tempted....

I ran 87 for about a year, then ran 93 for about 6 months, noticed no difference, and went back to 87.

Why do you exclude the VG?

Post by **MinisterofDOOM** » Mon May 05, 2008 8:32 pm

VG just isn't as advanced so it can't make up for crappy gas as well as other Nissan V6s. You may well still be fine running lower octanes in your VG. But in hot or humid climates during the summer it might cause knocking. That's why I don't run it here: in the summers it gets really hot and when you combine that with crappy gas you can end up with a car that feels below par.

Makes sense.

I just wish I could figure out why my VG idles weird. It didn't change no matter WHAT gas I used

In 2 1/2 years and 61k miles on my 2006 G35 Sedan, all I use is regular with no problems

20cents extra/gallon is worth it. we're paying so much at the pumps anymore that your wallet won't even notice a $3 diference, but your car will.

I guess I'll just copy my post on the same subject from 2 weeks ago.

maxhopper97 wrote:The fuel maps are designed to run most efficiently on premium. Using lower grade fuel will result in the knock sensor retarding timing and therefore decreasing performance. By decreasing performance, you get worse mileage per gallon.

For example: Say your standard fill is 15 gallons. Using regular grade fuel saves you $3 (saving $.20/gallon). Using permium you get 28mpg. Using regular grade you get 26mpg. Computing that out to miles per fill equates to 420 miles per tank with premium .vs 390 miles per tank with regular. That is a 30 mile difference which is over 1 gallon's worth of fuel, which at $4/gallon: you just lost over $4 to save $3.

This is just an example, since I only run premium, I have no idea what kind of mileage my Max would get on regular. This is just to point out that saving money on the front end could wind up costing you more in the long run.

to all you thinking regular is just as fine as premium...YOU'RE WRONG!!! look what i found: http://www.dynospotracing.com/octane.htm

and the dyno test is mid vs premium so what do you think it would look like with reg 85 oct? it's not about the power alone but also about your knock sensor.

I running 116 daily lol. No problems here.

i bet how much is a gallon though? bout $20?

Post by **kzoosho** » Sat Jul 05, 2008 1:05 pm

5.99 a gallon here. Not that much more than premium imho

Post by **allensteiner** » Sat Jul 05, 2008 1:18 pm

not too bad. i thought about getting a barrel of toluene and mixing it in with gas. you should look into that - a lot cheaper and can give you more octane than your car can handle

What about E85 I have heard that ethanol is like 110 octane is this true? I know all the indy cars use it so it must produce some decent power. In places like Brasil they use pure ethanol and its half the price of regular gas...only if it worked in the cold

Post by **lowblocks** » Mon Jul 07, 2008 1:03 am

my friend put 89 in his 01 Cali spec max and the car ran like **** the car kept shutting off. so now we put 93 with a octane booster

E85 only works correctly in cars that are designed to run on it. It's octane rating is higher than normal pump gasoline, but it's closer to 100 than 110. Ethanol CAN produce good power, but motors must be designed specifically for it. Flex fuel (dual-fuel gas and/or E85) engines found in commercial consumer automobiles run less efficiently on E85 than on gasoline.

And the reason Ethanol is so cheap in Brazil is because their economy and infrastructure support it. That is not the case in North America.

Post by **D-Maxima** » Mon Jul 07, 2008 8:15 pm

It would cost so much to put in place the infrastructure to do that...

the 00 Max pings on 87, so we run middle grade or prem only

Unless you're running with some boost, don't do it. You'll blow a ton of money for absolutely no gain.

There is a lot of talk about blowing the knock sensor using low octane fuel... your knock sensor isn't going to blow because you use low octane fuel. The heat cycling of the engine is far worse on the knock sensor than the sensor hearing extra noises. Your engine is constantly making different noises that the knock sensor constantly "hears", what it does is listens for a certain frequency that the engine makes when pinging and retards timing to prevent it from pinging anymore. The knock sensor can even pick up "pings" from something hitting the exhaust or engine and trigger the ignition retard in the ecu. If you knock sensor happens to die when you put in low octane fuel it was either its time or was already dead.

My step mom had an Infiniti i30t for years and she never ran her on anything but premium... Right before I bought the car from her, my dad was driving the car and running it on like 83 (reg. gas) & told me that nothing would happen to her. "its no big deal". Once I buy the car I cant quite afford premium, so I still with the special/mid-grade gas... Next thing you know she's running rough, starting up ****ty, and just not handling to her fullest. That day i switched to premium & havent had any problems since

Oh... DOES ANYONE KNOW HOW TO MAKE THE LINING RIGHT ABOVE THE BACK SEAT STOP RATTLING FROM MY SYSTEM??? its not bad but it could sound better
