Bringing up an old post here, but I have not been here for on these forums for a while...
Gas like oil is a touchy subject for sure isn't it. We all have our bias, likes and dislikes.
Here is what I know. 87 Shell vs 91 Shell here in the Imperial Valley, CA. Price difference is about .40 cents a gallon. I choose Shell over Chevron for price. Where I live, Chevron is on average .20 cents a gallon more than Shell. Crazy.
I was always under the impression that V-Power had more detergents than the 87. Not only does it have more detergents, but has other stuff in it that helps lubricate things and keeps the fuel tank itself cleaner. So maybe its all hype, but that is what I believed.
Now this is from the Butt Dyno and not proven, but my VW GTI requires 91 or higher fuel per the manual. My GTI is an MK6 that does require premium fuel vs the MK7 that does not.
When I put in ARCO 91 as a test, which is also a "Top Tier" fuel, and I did so for one month, on average about 4-5 fill ups, going back and forth to work I would get on average 25mpg.
Shell VPower, on average, same route to work, and all nothing really different, netted me 27mpg on average. Not to mention on the Butt dyno, the car just felt more responsive and eager to go.
So, lets step out of the more modern DI, Turbo car for a moment and step into my 2000 Dodge Grand Caravan with 155k miles on it 3.3L V6.
Same Test, Shell Got on average 1=2 MPG's better.
So I said, ok, will put Shell 87 in the Grand Caravan and give it a go. Mileage was the same as the ARCO 91 fuel.
So, what does this tell me? I am not sure, as far as I know the Dodge does not have Variable Valve Timing or anything. It does have a knock sensor so I am sure it can retard and advance timing to some degree, but on the Butt Dyno again, the Van even seemed more "eager".
So the question is? Is the peppier car, truck or van worth .40 cents a gallon more? For my VW the anser is easy. YES because it needs 91 anyway. For the Van? I cant say. I am not sure if the 91 is actually cleaning up 17 yrs of carbon in there or its doing nothing. I do know it is peppier, and I do know it got better mileage. But worth $4-$5 dollars more per fill?
For me? I am a performance guy. I me heck, there are people that put on $400 intake systems and net ZERO HP gains, or a $1000 exhaust system and net what 5-10 hp? So if you can yield more MPG's then it on paper anyway is performing better. So it would be worth the money. Right?
We all can go back and forth on this for ages huh? We can throw in winter blend vs summer blend and wow this can go on forever.
In the end its all what your willing to pay, and what you can afford. Ultimately, that is how you will choose.
