Hello all,
Everytime I fill up the gas from Shell Station that I got a better mpg. It's about 16-17 and other Gas Station is just 14-15 (all city driving).
Is this true to give me a better mpg if i alway use the "brand name" gas station? I used Premium 93 most of the time.
thanks |

I usually get better MPG right after a can of octane booster or fuel injector cleaner, but that usually corresponds with an oil change. I get 93 at RaceTrac or Cowboys. I did notice on my trip this weekend, 1K miles roundtrip birmingham,al to blacksburg, va, that on BP 93 I got 24 MPG, which is pretty good considering the mountains of Tennessee and Virginia we drove through.
The worst mileage I got was 13.5 driving from my house in birmingham to my job, a huge hill to climb, for about 2 miles, on Chevron 89. |

If Shell (or anything single company) has some magic ingredient in their fuel that would raise MPG by a whopping 10%+ you can BE SURE that it would be HUGE NEWS.
I don't doubt that in your casual "fill-up & check the MPG" routine you may have seen a few higher MPG readings, but I suspect that it may have also corresponded with some other event that IS known to give better MPG.
Maybe it related to getting an oil change/ checking tire pressure. Maybe that tank you idled a bit less than on other fuel. Maybe it was a bit cooler and the A/C didn't run as much. Maybe it was less windy that week. Maybe the freeway was less crowded. Maybe you coasted a bit more that tank.
You can be sure it is NOT the fuel... |

| Perhaps it didn't have ethanol. I have run across ethanol-free gas at various stations. Sometimes it's the 87 and sometimes 93. But I always get better mileage when it's running 'pure'. |

In our '04 Touring, we get 23.5 to 24 mpg between Birmingham and Blacksburg on 87 octane, driving 70 plus mph with a/c on. We make the trip two or three times a year, and the results are always the same. |

There have been many, many threads on this subject.
I recommend you check them out.
I agree: If shell gives you 10% more mileage, there would be a waiting line miles long to get their product!
I think the consensus on this board is that the cheapest miles per gallon is the cheapest gas! With very minor variations, all gas is fungible. So there is very little reason to pay a premium for any particular gas.

It's all a matter of physics. You will get better fuel mileage on lower octane gasoline. An 87 octane fuel has more BTU's per gallon than a 93 octane fuel. The fewer the BTU's the less energy per gallon. The less energy results in poorer fuel mileage.

I thought the MDX required premium (91+ octane)? Is this not true? |

Dear emdeeX
I see you are new member. WELCOME.
There are many, many many threads on premium vs. regular gas. Recommend them to you.
FYI, I use regular in all my cars. (2004 Audi 8L, 2003 Boxster and 2003 MDX)

I used both Premium93 and regular 87. I did not feel the different for performance. But for the engine, Do you guys think this is bad for long future?
thanks |

Acura words it in a strange way, and even gives somewhat conflicting information, but my manual says 91 octane "recommended" but 87 is minimum "required".

There are many threads on Premium vs Regular. Many members run regular. In the rare cases where engine knocking due to incomplete fuel detonation may occur, the engine computer will retard the timing resulting in slight HP/mpg loss. However, in normal driving it is unlikely to occur (unless your normal driving consists of racing and towing all the time :D ). |

and was wondering if its worth putting in the expensive stuff just for the level of detergents alone??:8:
No it is not. Choose octane level by your owner's manual's recommendation, not promos.
Today's fuels have sufficient detergents to do the job at any octane level.
'Sufficient' is the operative word. You can always dump in a bottle Techron every few months if you are a little OC.
Shell is very creative with their words. They would not want you not to buy Shell because you choose regular or mid-grade.
Look up Top-Tier and you find major gas companies (including Shell) support the use of the best detergents, regards of octane. |

| I suppose I could click that link and make sure, but I'm too lazy so I'll just shoot from the hip and say that I remember that only Shell's premium grade (V-Power) was the only one that got the Top Tier certification and the regular and plus grades did not. |

Not according to the standards set by Top Tier, not to say some grades may well exceed the requirement.

Well well. Not sure where I heard it from that it was the V-Power only that got the stamp of approval, but this says all grades are good...

| Yep, part of the Top Tier certification requires that all grades be certified, not just premium. |
