Anyone else notice this, or it might be psychological ? I could swear that the last time I got gas (was just about on the 'E') the car has felt stronger/more responsive. Now the problem is I dont remember where i got it from I'm thinking that since they now have these government required mixtures going on, and what not, it is more likely than ever that the 91 or 93 we get for the CL-S is gonna vary in quality from place to place. I know some replies will say it's the weather (temp.) but I don't think so at this time of year in New York.

 

I know my car runs better in the cold, and at this time of year we get mad temp changes throughout the day. 60 during the day and hi 20's/low 30's at night. It gets cold real quick when the sun goes down.

I've never run anything other then 93 in my car, but since the CLS is equipted with knock sensors, the computer will retard the timing if you're running low octane gas, which will result in a slower car.

I've heard stuff about "winter blend" gas, so maybe the stations are switching over to the summer blend

 

Seek help now....

 

I've felt a great difference when I switched from Shell to Amoco. Engine feels stronger and smoother.

 

maybe it was because your car was ~ 100# lighter from being out of gas.

 

i laways feel a differnce when i use sunoco or amoco compared to hess or exxon...

 

Thanks, Vin, see Eggplant it's not all in my head ....hhaahhaahhaa.

 

Now if I could only remember where I got that gas.....

 

Well, how about a group rate on therapy then!!

 

Funny you should say this cuz i just filled up about 20 minutes ago and on the way home the car felt faster. Guess i must be

BTW i got 17.2 MPG.

 

car feels good on Sunoco 94

 

We Octane challenged Californians ( 91 ) hate you

 

This must be it!

 

my car feels stronger when I fill up at Mobil One. Shell, Texaco, Exxon doesn't feel the same.

 

i dunno, so far ive only used shell, mobil, and chevron and it feels the same to me?? Maybe im retarded and can't tell the difference.

Oh and If i'm driving like 70% city and 30% high way and getting 20-21 mpg, is that good?

 

there is a differnce in gas...

 

Good to see you are enjoying the Mods! I can never get my car much over 20mpg either. Don't want to let those vtec cam lobes go to waste.

 

All gas is the same. Only difference is the additive packages each of the brands use. Independent brands use cheaper and lower dose of additives.

The additives are put into the tanker when it loads. Until then all
gasoline is basically generic. There is not that much difference in
the additive packages.

I work for one of the major oil companies.

 

i always use amoco 93, once in a while i will use sunoco 94

 

Hellz yeah.

However with the way the price of gas has been going up I really need to start driving more conservatively.

 

^ werd my gas tank was 35 bucks

 

25-30 bucks to fill up these days here too dammit... 1.75 is the cheapest i can find 93 gas.. and ive seen it at 1.89 in some of the neighborhoods. they must think we live in cali instead of texas!

 

cheapest here is about 2.35 for 91 octane. dont complain at the rate you pay.
