Fuel Power vs. V Power

[MolaKule]

I had purchased some V-Power gas in Kansas City area and on the way home I seriously thought my fuel filter was clogging up, especially with the lack of power on hills.

That stuff sucks!

So now I carry FP so if I am forced to get gas from Shell, then in goes FP.

I've been using Shell's V power gas for a few months. My car [lightly modified Ford ZX2] seems to be a little more sluggish with this fuel, and will get occasional spark knock that is not there with other name brand premiums. On paper it looks great, though!
After reading good reports of Fuel Power additive in this forum, I ordered a gallon. Only 100 miles later, the engine smoothed out enough to notice [shifter knob occilates 1/3 as before, seat of the pants is smoother, too]. V power's cleaning ability is light.
I've just read Fuel Tanker Man's excellent post, and will now buy Amoco BP premium, and use fuel power. Haven't checked MPG yet.
F P rocks the house!

I noticed the same thing throughout my tank of VPower. Car runs great on Shell 87 (which its had basically all its life), or on Mobil 87 that it's had in the last few tanks.

I just buy whatever 87 is cheapest, typically Murphy, and throw the FP in with it...

Weird, I tried V-Power from shell fill up my '96 Cherokee Jeep 4x4. It seems smooth and little lost power. When my tank goes to near empty and I fill up shell 87 octane. It improved MPG from 270 to 340miles.

I'm 100% sure your increase in MPG were not related to using Shell V versus Shell 87 oct.

You must of did something, drove differently, changed the oil and filters, maybe a tune-up.
That's approx a 26% improvement over the previous tank. Something your not saying caused this much difference!

Steel Blue Wind Rider, I have not change tune-up or change oil whatoever. It's same what my jeep have. I tried test with Acro, cheap gas station and it usually give me 270miles (gas indicator reach E). After I used Shell gas and it gave me 340 even 2nd time yesterday i drove to oxnard near ventura from Riverside about 150 miles and total over 300 miles the gas indicator showing 1/4 left gas in tank. mmmm

my habit driving always same as usual using cruise control even in city road.

I will test with Acro gas again tomorrow and test how it goes.

Judging your MPG by the fuel gauge alone is not very accurate, you need to know how many miles you drove and how many gallons you used to do it.
My own Cherokee will often still have 2 or 3 gallons in the tank when the gauge says E.

Fill that baby up to the brim, drive it. When you refill it, divide the number of gallons into the number of miles you drive.

My mileage doesn't vary much by whether I use Chevron or Shell, usually 19-21 mpg in mixed highway/city driving.

today i drove and got 360 miles and i filled gas 17 gallon. few days ago 340 miles same 17 gallon from shell gas station.

I noticed similar issues with V-Power 95 in Poland and Holland, but not with V-Power 99+ called also Optimax (Germany) or Racing (Poland and Czech Republic). Looks like V-Power 95 is just an ordinary 95 from nearest refinery boosted by Shell additives. May be 99+ has chemically different formulation, but I never had a problem with it, just this 99+ has one peculiarity: being perfect at high RPM (over 5.000), Honda engine feels certain weakness (in comparison with 95 gas) at low RPM (2-3.500) on direct gear.

BTW, symptoms described here by number of users remind me the issues Castrol TBE additive:
