does anyone use Walmart gas

[Mary K]

I have never stopped at BP station for gas because it always is the most expensive gas in town. I usualy get it at the Murphy station because its the cheepest, and close to the house. But I have noticed that my mileage is not as good as it used to be here lately.

But, I think I'll not be stopping there anymore after CD's GF story.

Ill make the change to Citco, and see if my mileage improves. Might be worth the few extra pennies I spend.

I always go to Chevron becuase I like the additives and they are the only place in town that doesn't put ethanol in their gas.

Chevron and Texaco (same company) use Techron. It's a good additive.

I noticed when I went to the Palo Duro gathering that none of the gas stations had 91 octane, which is what my car calls for. In fact, all the grades were a point lower, IIRC.

BTW, don't use a higher octane gasoline than what your car manufacturer calls for. You are wasting money.

I've noticed that too when I'v traveled. I don't know why they do that but it's always been that way.

There's a ton of corn grown up here which is why everyone is putting ethanol in their gas.

Gasoline producers are using ethanol primarily as an oxygenate to lower emissions... because MTBE was poisoning ground water due to leaking gas station storage tanks.

(Don't use E85 in anything but a Flex Fuel vehicle. The National Ethanol people won't be resposible for damage done to fuel systems in non-Flex Fuel vehicles from using too-high-concentrations of ethanol in gasoline.

Automakers are designing fuel systems to handle increasing amounts of ethanol, but at this point in the game, +/- 10% ethanol is fine; there's enough of a gasoline "buffer" to protect fuel system components...)

True that. Octane is merely resistance to pre-ignition. In other words, higher-octane fuel burns slower. Using higher octane than what your engine's compression and state of tune (now in software form!) calls for will only decrease performance, albeit almost imperceptibly.

One can use higher octane to a gain engine torque only when igniton timing is advanced.

There is the rare case where a person has used, say, 89 octane in his 87-octane-spec'd machine and noticed an increase in fuel mileage... now, that increase is possibly created by several factors (true "average" fuel economy figures should be determined by more than just one fill-up), but in this case the engine in question has been known by tuners to have an "over-anxious" spark knock sensor... and it could be that the 2 pts-higher octane created a combustion environment where the knock sensor remained somwhat quiet in it's communication with the PCM and ignition timing was never pulled (retarded) allowing slightly higher torque output and the result was a slight gain in economy.

But that's a rare scenario... and if that were the case across the board w/ that particular model odfcar, then the car should be spec'd to run on 89 instead.

I can appreciate the environmental aspect of ethanol, but I don't appreciate a loss of horse power in my fiance's already anemic four cylinder.

Turbo!



There're many kits available.

[Justin & Katy]

I love where your heads at!

I'm going to get a Titan for my TV and I would love to put one on that. I've read several articles where car makers are going to be putting turbo kits on many of their new cars in order to increase fuel economy.

Spanks!


CD more than likely has his finger on the pulse of that action.



I'm out of the loop as of last year... too busy pondering then designing my teardrop. Chassis's almost ready to get welded up!

[Justin & Katy]

Cool. Be sure to start a build journal.

Also, don't forget, when the gas has 10% ethanol, that means that 10% of the fuel being consumed is coming from a renewable resource. We tend to forget that there is a limited quantity of fossil fuels in the earth for us to gobble up.

Sensitive subject right now ... but I buy my fuel from Flying J or Maverick and I have for years. The crude comes from wells in Wyoming and it's refined in Utah. Decent quality, and usually on the lower end price wise. No, foreign oil for me if I can avoid it.

The BP situation is a sad one ... if it can be proven that they were intentionally cutting corners, they should pay big time. But right now, running them out of business isn't (in my opinion) a good idea. If BP ceases to exist then the liability for all of that damage will fall right upon the taxpayer.

My opinion ...

1. Stop the flow of oil, and get busy cleaning it up.
2. Find out exactly what went wrong.
3. If the problem doesn't exist on all of the deep water drills, lift the moratorium on drilling (this was a mistake by the current administration in my opinion as it increased the economic impact of the situation.)
4. Hold those responsible accountable for their actions (not the corporation as a whole, but the people who made the bad decisions.) (BP as a corporation will have to step up and make reparations)
5. Prevent anyone else making a similar mistake (this doesn't mean putting the Gov't in charge or regulating the industry to death.)
6. Open up drilling onshore and in shallow water where problems can be dealt with.
7. Keep working on those alternatives ... we have a long ways to go yet before they will be able to replace oil.

Hopefully we can get things under control before things get much worse ...

True that. Octane is merely resistance to pre-ignition.

Ah, finally someone who understands!

Won't buy from CITGO (Hugo Chavez)

Otherwise, I buy the cheap stuff...BP,Murphy, whichever keeps my Ford under it's own power

Ethanol is not yet AS efficient as it can be.
Peanut oil in a diesel would be better!
Or, cheaper still; one of those water burning carburetors form JC Whitney.

Course, my ideal would be twenty miles from town and Horse powered!!

Fueled on and creates renewable energies....

I've noticed in Arizona I get 21 miles per gallon on the summer formulation, and 19 mpg on the winter formulation, tank after tank, in my 2007 Nissan Frontier.
