using 87 octane...
#41
Bobo- forgot to use 'American' gallons. Yes, I was quoting Imperial gallons. And I also happen to drive hard in the city, and at 75mph on the freeways and still I get 400 miles in a tank. If I'm highway driving, I get 500+ miles on a tank.
Couple of points
- my tire pressure is always perfect (I'm ****)
- I use K&N airfilter (slight increase in fuel economy)
- I always use cruise when possible (it's hard to control such a powerful beast without accidentally speeding)
- I turn off my climate control or air conditioning if I can
- I always drive with my windows up
- 100% Synthetic oil Mobile 1 in the engine.
- car is always kept in top shape.
BTW - tire pressure has a huge impact on fuel economy. I think for every psi, your fuel economy is thrown a few %. For example, I had a couple of tires on my old beater that were low, fuel economy was terrible for a week (filled up 100 miles sooner). Pumped up the tires, and presto, regular fuel consumption restored.

I have never run synthetic oil, but am switching to it after my AutoRX clean and rinse. I am going to use Esso XD3, 0w30, full synthetic year round.
It is the perfect oil for your Calgary climate and is significantly cheaper than Mobil 1 and is showing better UOAs on BITOG. Do yourself a favor and deep six the Mobil 1. Read all about the XD3 on bobistheoilguy.com
No charge to join and search function works and is easy to use.
PS you neglected to add that it is as flat as a pancake in Calgary and for miles around, unless you get into the foothills west of the city.

not sure about long term effects tho............

Make sure there mapathlene or whatever ones, but i still wouldnt put em in my tank, im sure they will leave some crap behind.

(popular belief.. that I follow as well) thus the ECU will change timing....

for those of you getting 400+ to the tank. What are your driving conditions?
I mostly drive 70% highway. I go in at work very early so I can usually do about 80-90MPH
At arounf 85mph my rpms are at 3.3-3.5K rpm. Its gets hot in here like so use my A/C all the time.
I don't blame my wheels because even with my stock wheels I get the same around 320-350miles to the tank.
hate these gas prices

well guess I'm stuck with bad gas milage.
Freeways here are very new and wide. Everyone drives at those speeds so in order to flow with traffic I must go at those same speeds. These are the times when I wish the Maxima had a longer 5th gear so I could do 90 at 2-2.5K

Or a real long 6th

A common myth is when having your A/C on, on the highway, eats more gas than having your windows open. A special new cast on channel 7 did an investigation on this. Having your windows open on the highway creates alot of wind drag, wind going in the car, slowing the car down, unless of course, you have no rear window and the air just flows through. Having no wind resistance on the highway, ( windows up ), A/C on, will give you better fuel economy. Just opposite around town.

You still have wind resistance on the highway with the windows up, just much less.

It doesn't run "hotter", nor will it do any damage to the engine. The only thing running 87 will do is annoy you and give jerky acceleration when the ECU is constantly pulling timing since the ignition map is set for premium. There are people here with very high mileage that have run NOTHING but 87 octane and the engine is perfectly fine.

For example, if your Maxima gets 30mpg, you get ~500 miles on the tank (what I get). If putting in 87 octane nets you 430 miles, that's a 13% drop in fuel effiency. If premium 13% more in price, then yes, it's economical. If it's not, then you're actually wasting money buying a cheaper fuel.

There are hundreds of articles on this issue of octane misfiring.

The moment you press any button other than Premium, you can be damned sure that my bullet will take out you and your car. The armor piercing bullets will finish you first and then take out your car by hitting the gas tank. Your car will then thank me.
Nah, Im just joking dude. Hope that scared you away from low octane rating.

Having at least 3 O2 sensors fail - at costly repair costs to my wallet - I'm sure was due more to a lousy Nissan-spec'd O2 sensor.
I figure that Nissan O2 sensors must be a horribly bad design to be so easily affected by lower octane fuel, so I spend the extra 2-3 bux per fill - and keep the performance where it should be.
