Gasoline

Is it true that the gasoline in the wintertime has a a differnt mixture than in the summertime and hinders gas milage? I heard this and dont know if its true or just a myth...I dont remember my car getitng such milage in the summer (maybe because I didnt track)
Thanks

It certainly is true, if the companies mix it differently in the summer and wintertime.

So this really CAN cause a drop in gas milage? As significant as 5+ MPG?

ok, he said that if the companies change how they mix it, it might be diff mixtures, u will not get different gas milage b/c it stays the same octane lvl, the octane dosent just dissapear and make your engine suddenly run worse

I hope to god it lowers gas mileage. I'm averaging 14 mpg shifting at 2000 rpm.

Yes, but some mechanics have told me that my car gets around 18 in the wintertime but with SUMMER GAS it should hit up to 25MPG...I just heard this a few times nad wanted to know if its really true or not

I'm averaging around 15 all highway miles, not floored much at all but maybe twice or so a tank, although I am having problems going through emissions os once I get it back hopefully mroe around 20 or so, also I am checking the compression ratio in it as that may have a hand in it as well as the 02 sensors and the other emissions shit.

Yeah emissions are a bitch. I never got the problem fixed, but I did spend $300 so I was able to get a 2 year waiver. Sad thing is, I have 200 compression on all cylinders. However I think the stock FPR in my car cant handle what the Walbro is putting out and my plugs and wires are of unknown age. But my little 152ci engine shouldnt be getting this bad of gas mileage, and I use 93 octane!

I got a 3-speed auto with no overdrive that can explain my problem maybe...im still hoping that its winter gas screwing me like this.

I use 87, once I bump up my timming I will use 93 octane. As for a tune up i have done this for 390$... New Plugs Wires Fueld Filter PCV Valve, throttle body cleaned and injectors flushed and cleaned. Ford Racing wires and some nice Autolites. I smell gas when I start the car up though and it is mostly bone-stock so I figure 400$ mroe into emissions things and I should bump up the gas mielage and not have to worry about emissions next time. Why I don't want a waiver is how will that help my 14-15mpg mileage? It won't I need to fix the problem now, especially if I plan to go from 2.73 gears to around 3.55. I'll get like 11 then and really be ****ed so yeah. Of course like I said possibly boring or a whole new block (306) eventually but eventually is far away so yeah.

All I can say is what? I can outrun you no problem my friend Gas mileage doesn't always go hadn in hand with performance, trust me I have screwed around with some Talons, Civics, and of course Neons, and your sport isn't worth shit against my car, even if it is 17 years old and stock. :-p btw yes I have raced a sport.

there is no differenc in the gas, its all about conditions in which you drive. Did you think that maybe manufacturers are making cruder and cruder gas as well, seeing as how with the problems with the pipelines durin katrina, they moved to a cheaper process of producing more gas, so it is cruder and cruder.

i dont know how much sense that makes, but they dont change it for summer or winter, i know that for a fact, cost them way to much. but rember, we are in the middle of friggen gas crisis
