Is this normal?: I put 6 oz. of VSOT in my oil (6qt. capacity) right before I filled up my gas tank (31 gallon) a week or so ago. Now I've already got about 20 miles more on this tank and its not empty yet. I will get gas tonight or tomorrow morning and do the math but I know I'm getting better MPG already. That's the only change I've made on this tank of gas. Three weeks ago I put 5psi more in the tires and noticed no difference and about 6 weeks ago I put new O2 sensors in and didn't notice too much of a change. I know one tank is not enough of a test but my mileage per tank never goes this high unless I'm on the highway 100% of the time and I wasn't.
I will report back the actual improvement, but has anyone else seen this?
Mileage increase with VSOT?

I have noticed a difference in engine tone and power, but nothing around fuel economy yet. I added the whole bottle to 7.5 quarts of oil.
By the way, what are you driving that has a relatively small sump and huge gas tank?
Where do you find VSOT? I have looked at all the auto stores around (AZ, Napa, AA, PB) and never seen it.
I have gotten 3 bottles so far at Pep Boys here in NC. You say you have been to Napa. Did you ask if they could order it?
I've been to Napa, and Lee, and about 4 others. Lee called Valvoline and they said its discontinued and that the additives are in their Maxlife oil products and their "Engine Treatment". I finally found some VSOT at Pep Boys. Someone said Advanced Auto has it but the store near me doesn't. If you find it the price is around $4-5 for 15 oz. The engine treatment is $15 for 32 oz but I dont know what's in it.
I don't understand these "got better mileage" threads. There are 1500 uncontrolled variables (in a scientific sense) and a mileage variation is attributed to ONE. Air temp, humidity, gas temp, speed driven, gas vendor, gas formulation etc etc etc.
I wouldn't attribute anything less than 10% mileage change to any "one" thing. My car has a >10% difference in mileage which can easily been seen when
1) I drive 75mph instead of 50.
2) Outside temperature is < 32F

simple_gifts, I understand your point, however, I check my mileage every single time I fill up and the only time in the past couple of years that I've gone past ~400 miles on a tank is when I travel 100% highway. I finally refilled my tank this morning and am getting .5 MPG better than my previous 5-6 tanks after I put the new O2's on. Previous to that I was getting a little worse mileage. I realize that one tank-full is not a test but if I can maintain this improvement, I'll be sold on VSOT and I'll go get several more bottles.
