I used to drive a Toyota Corrola & there was a big difference in both grade & brand. I just got a Chevy S 10 so I'm wondering if that will true for it also. I know in general larger motors aren't as sensetive since they have more power anyway.

I also noticed that my truck is getting around 3 miles better per gallon since I first got w/ the higher octance Shell & BP gas and synthetic oil.

The octane rating is what matters. The octane rating determines how much energy the gasoline can give your engine. The higher the Octane rating, the higher the power.

Yes... sometimes it does. I had a Subaru WRX. The manual said premium. When gas prices went up I tried the next lower grade, and it didn't work out well. It knocked and made noise and my mileage dropped way down. That car was an exception though... it had a turbo and 4 cylinder engine mounted horizontally. You really had to go by what the manual said.
The car I had before that was a Chevy Blazer and I always put mid grade in it. It didn't require it, but it just seemed to run better and get better mileage with the mid-grade over regular.
The way prices are now... I'd say go with regular, then once a month or so when your tank is completely empty fill up with a higher grade and see if there is a difference in mileage and if the engine just runs smoother.

It's always been my understanding that larger engines need a higher octane. My 5.0 V8 in my mustang runs like crap unless I use mid-grade -- I also use mid-grade in my V6 Escape just because it's "supposed" to be a little better. I've had 4 cylinders in the past that ran the same no matter what grade I used.
My advice would be try the cheap stuff, and see how the vehicle runs, upgrade if you get sluggishness and pings. Most cars nowadays are designed to run on the low grade.

Your S-10 will run better on premium gas, but as a rule don't use premium unless your manufacturer calls for it. Otherwise you're throwing money away. I imagine the synthetic oil and maybe unwittingly, your improved driving habits have a lot to answer for with your better mileage. Poor vs. good habits will realize the numbers that you got more than oil or gas itself would.
Synthetic oil is fine, I have to use it in my car as added insurance against sludging. But I've seen more than a few cars and trucks use plain engine oil and go for 200,000 to 300,000 miles. Frequency is the key.

It does not matter much which brand gas you use. They all pool their supply, so it comes out the same no matter where you purchase it. The only exception may be Chevron/Texaco that add a cleaner that seems to be more effective then others (IMO).
The grade of gas you choose depends on your vehicle, but for cost reasons, you should choose the lowest grade gas that your car can run without knocking. For most, that's the 87 octane grade.

once you assert "grade", you recommend customary or accurate fee, yet once you communicate of the emblem of gas, then there is little distinction contained in the call style gas and the Costco gas. Costco buys its' gas from an same refinery that call style gas co's get gas from. in reality, mainly, the Costco gas is Chevron or Shell/Texaco and so on., in basic terms that Costco agreed to purchase a bulk quantity at a bulk/low cost value. This gas is in a lot of circumstances the surplus gas from the numerous style companies. What you want to concentrate of is: a)do not fill-up even as the tanker truck is refilling the floor tanks at a station(the sediment stirred up and is going to the pump, and some stations do not substitute their pump filters in many circumstances). b)keep away from stations that do not have quite some site visitors/customer volume, as gas instruments longer of their tanks and may want to nicely be degraded. c)come across a style that does nicely on your motorized vehicle and follow it. This avoids the variables once you've complications.

I live in the reformulated gas belt of Milwaukee county, and i feel that i would be cheaping out on maintinence if i use regular, so i stick with using mid grade. I agree with what this elderly lady i know said about buying gas. Her late husband told her to always buy the same brand of gas with the same octane rating. I think i agree with her because of the problems people had here with using Citgo gas that clogged fuel injectors.

Of course it matters!!! Higher octane seems to work better in my blazer. It doesn't take as long to accelerate and the gas seems to last longer. I never go to gas stations that are not as popular. The gas sits longer and has more "trash" that will clog up your filters. My uncle got gas that had to much water which ruined his truck. Shell has the best gas. It is made to clean your engine and improve performance. Also, keeping all of your filters changed including the air filter will improve gas mileage!!

Yes.
Especially if your car is supposed to have a higher octane in it.
If your car is knocking or pinging, you need a higher octane fuel, otherwise you will continue to do damage to your engine.
Also, higher octane fuels burn more efficiently and therefore produce more power and therefore and you get more miles to the gallon.

Brand of gas doesn't matter. Grade of gas is recommended by the car maker - read your owners manual.
