Does fuel Matter

hi I'm new Got a Outlander XLs fully loaded. I full it up with Plus since i got it. i was wondering if it matter if i put reguler in the tank.

I don't think it makes a lick of difference, aside from the price. I have actually heard that it can be harmful to put any other type of gas than recommended, even if premium is supposed to be better. I can't say for sure, because I have no knowledge in the area, but you are pretty much just wasting your money.

Regular is all the Outlander needs.  You're wasting your money.

If the manual recomends regular, then do that. If it recomends premium, then put that in.

Do a quick search, its been asked a few times already. Just use regular. I have never found anything good about using fuel with higher octane than what is suppose to be used.

Yup, always use the reccommended octane.  Deviations either way will cause performance and fuel economy loss.  And more $$ out of your pocket.  Remember cars are computer controlled, and programmed from the factory expecting a certain octane rating.  Changing this means the ECM has to adjust for it.  And where one adjustment is made, another must be made to compensate for the first, and so on.

regular. i tried it with plus and prem. no difference in mpg or performance. just wasting greens.
 
 

really? I usually fill up with Premium, but sometimes I fill up regular and it almost feels that there is difference in rapid acceleration. I like to floor it sometimes ;)
 
Anyone done real tests?

Hello, I just bought the car, they givin me to mee tomorrow, I had the I4 cyl, quick question
 
here in Panama we have Premium 95 oct and Plus 91 oct, Just want to know in the US, what is
Regular, Plus and Premium
 
because some of you say the car runs with regular

87, 89, 92

Some gas stations have prem at 93oct.

I just fill up the thank with Plus 91 Oct, the manual said any gas just it has to be 90 or higher
 
great, just to come from a 95 oct with the Evo..
here are just like 10 cents the difference from one to another

I had TSX prior to Outlander and it explicitelly stated "Premium only" in the dashboard and near gas tank.
 
I didn't look in the Outlander's manual, but I read before and heard from a dealer that it runs on a regular. If your manual says using 90 or higher that basically means Premium gas which I don't think is true...

I just bought a 2008 XLS and the manual states 87 or higher, so regular is just fine... any other grade is just a waste of money.

I think it's more important to pic a brand name gas (one that does more than the minimum detergent standard) and that gets alot of traffic (fresh gas)

What brand do you use? last few times i used Gulf and Lukoil. i might start to use Shell sinces its at least in the list

I've always used shell, forgot why I started using it, I probably read somewere it was one of the few companies that used good qualitty additives. I'm kind of happy it was in that list, I knew shell was agood company since I've had 2 cars both make it past 150,000 miles on shell, but this is conqrete evidence I guess.

BTW, who maintains that list? Strange that BP is not on the list.

There aren't that many suppliers, maybe 3-4 in a given area, even the no-name gas station get there gas from a major supplier, I've never heard of a no-name refinery.  Certainly the argument of using a high traffic gas station is a good idea.  If for what ever reason the gas is being contaminated, at least the contamination is diluted and you get less of it per tank.
As far as additives, Shell had to change or remove their additive a few years ago, after realizing that it cause some major issue with some fuel injection system.  I would rather not have any additives at all since MMC says to not use any and if it does cause problem, you 'ed be stuck paying for the bill or suing the gas company (this is what happened in the case of Shell).

In short:

Regular is the "minimum" recommended octane for the outlander.

You can use higher grades with no detrimental effects, and possibly no beneficial effects either.
