fuel type

[versa071979]

just wondering what type of fuel is truely the best to run in my 07 versa i also have an 09 altima with the 4 cyl in it i would like to know which fuel really works best with these engines nissan recomends a grade no lower then 87 obvously but their manuel does not recomend what would be the best type to run

[robj80]

a car company usually doesn't endorse one paticular brand of fuel. They build the cars to work on all 87octane or higher unleaded fuel.

Try different stations and see what works best for you. Usually top tier gas companies are the best IMHO. If you have Chevron in your area give them a shot. They seem to be the most preferred.

87 is all you need - anything higher is wasting money in your engine.

http://www.toptiergas.com- look there for what the industry considers to be the best fuels.

Here we go again You will find as many opinions as there are forum members. Since I work for ExxonMobil, I strongly recommend their gas but any major brand gas is going to be just fine. I just avoid really old stations that might have old tanks with who knows what in them. For that matter, I know many people that fill up at the grocery store pumps and they are just fine. Chevron gas may come from and Exxon refinery and vica versa depending upon your location. The only difference may be the additive package. You will likely hear many opinions on those additive packages, but bottom line is they are all good; otherwise you would hear of issues.

PS: look for the Tiger or the Pegasus!

I was driving 40k miles per year. I calculated gas mileage every single fill up. I drove the same route every week. Only variables being weather. My findings were the best gas mileage came from Sunoco / shell, then the next group would be citgo/gulf followed by mobil (exxon) / BP and lastly stop&shop / cumberland farms. These were so consistent that I could guess my cars mpgs +/-1gallon everytime.

These were my findings and in no way am I saying one is better then the other. I'm just posting my results. You should test the gas yourself. If you looking for greatest mpgs just calculate everytank. It's kind of hard if you don't have a set route like I had. Because once other things come into play it throws your numbers all off.

I get the worst mileage in my cars with Shell gas...do your local Sunoco/Shell stations use an Ethanol blend? Mine do, which kills power (according to my butt dyno) and mileage is noticeably lower despite similar driving routes/conditions. Have I mentioned how asinine it is to turn food into fuel? Sorry, I'll suspend my Ethanol rant for now.

The fact that you have the same route does offer some consistency to your findings. I very rarely fill up with anything besides Exxon or Mobil just because I get a 10% discount before tax and have for the 29 years I have worked for them (the exception being our 7 years overseas). That more than equalizes any differences between gasolines. So hard though to apply your findings to other parts of the country due to different refineries etc.

+1 for Wagner. Us southern guys don't have Sunoco (as far as I know) and I've spent the majority of my life (14/19) years in the south. I always rock ExxonMobil in my Pathfinder and my girlfriend's Versa. Been the best brand for me. And obviously, always use 87 in the V.

I always see that you all mention numbers such as 87 octanes... Does someone knows why we have 91-95 octanes in Panama? Funny thing is that my Tiida has a sticker stating "95 Octanes ONLY", so I always spend more than others in gas (people mostly use 91)... I know I can use 91 if I want to, but it might lower the performance...

Oh, and by the way, Shell would be my first choice...

Certain countries use different types of octane ratings.

Using food for fuel is dumb to being with. It raises the cost of food because some of it isn't used for ingesting. More of it needs to be converted to ethanol and there is less of it for livestock.

The energy content in ethanol requires you to burn more fuel, therefore you get worse mileage. That's why you can't run E85 in normal engines. With the added demand in fuel, you need bigger injectors and a stronger fuel pump to get that extra fuel flowing.

Ethanol isn't the answer IMO. Hydrogen fuel is a stopgap that should be implimented until we can get a viable electric vehicle that goes 300 miles on a charge and doesn't cost over $50,000.

There are two calculation methods for Octane and you must go by what your manual says as Panama uses the other method. Fred

Yeah my finding would be totally different I'm sure if I lived somewhere else. I even use the same stations so who I'm getting gas from stays consistent. Meaning I don't use every shell or sunoco in the state. I just use the same one over and over. Because gas is different everywhere threads like this are almost impossible. Especially on a nation board. Some of my local boards the information is more useful as we are going to the exact same stations.

As far as ethonal goes we are mandated to have 10% in all of our gas. This is very dissappointing because it hurts my mpg's way too much. I am just about at 39mpgs now and if we didn't have ethanol I'm sure 45 would be no problem. I remember before all this crap was in the gas. My cars all got phenominal gas mileage. I think corn is to blame for all these gas issues we have ie shortages and price hikes. Bottom line is if there wasn't corn in the gas I would be using alot less of it.

Y Bottom line is if there wasn't corn in the gas I would be using alot less of it.

what happens when the feds mandate that we put food in our gas tanks. There is also an issue in getting ethanol to market on the east coast due to lack of adequate rail transportation from the corn belt. So in all their wisdom, we have imposed a tariff on imported ethanol which increases the gas price on the east coast. I just love government intervention.
