E isn't even close to an empty tank on our cars. There's still almost three gallons left when I hit E.

As for the not using gas in the bottom of your tank argument, I suppose it has some merit, but what about when your gas gets shaken around by taking some turns/hills/etc quickly, braking quickly, etc? Personally I think if it really matters it makes more sense to run your car down close to empty (remember, empty != E) fairly often and avoid building up tons of crap in the first place between that & shaking the tank up.

 

I'm just telling you things that have learned from fuel handlers course I took in the military. Instructor had been working with fuel for about 30 years so I trusted his knowledge.

You say it makes sense to run your car to E to keep from building up that crap in the first place? Well where do you think that so called crap is going to be going if it's not settling in your tank? It's going into your engine.

 

Yes, but not huge amounts of it at once as it would if you only ran your car all the way down to empty once or twice in its life, assuming that significant amounts of sediment really do build up in gas tanks over the years.

Btw, I do not run my car down to empty, that's just what I would do *if* I worried about sediment buildup. I run it down to E on the fuel gauge, which as I've said is very different. I find that running it down to E is a good balance between not getting too close to running out of gas while not having to fill up too often.

 

well iv filled my work truck with the cheap gas and have had fuel problems fuel filter cloged, broke down on the highway, so with my own indevers with this you see where im coming from and if you want to get back at the oil company's next time you need gas TAKE YOUR BIKE OR WALK!

 

anything besides 87 is worthless in our car without Force induction or seriouse HP. Anything higher is not only wasiting money because its worthless but almost bad for your motor because...High compression=higher end gas... we simpley dont need it, 93 will give u 1 HP more MAX, but you will loose it in the motor to wheels processe anyway

 

I use 91 octane Super-clean gas from Petro Canada. Although it might not have any benefit, it's *supposed* to contain the most tactrol which may benefit my engine if you believe the marketing hype. Plus it gives double points every once in a while.

 

93 all the way with me

 

THANK YOU! finally somebody agrees with me

 

Sunoco GT 100 octane, all day, everyday.

 

Chevron 91 octane.

 

i'm not agree with peolple say the 87 oct is OK...Each time i put gold gaz(91), and sometimes because i'm in canadian tire station, I don't waste my money and put 87 octane...EVERY TIME AFTER i say, never again i will fill up with cheap fuel(87)...For me I see a difference...the throttle response is better, and the sound is increse...

Before i had a dodge neon and have make the test with 2 octane....and the Higher octane was the better was performance...

It's my opinion....3$ for 1 week =12$ for a month...and 144$ by year...less than one coffee per day!!!!

FranK

 

sunoco 94 octane. around here its 2.27 per gallon hopefully it'll drop more and more

 

I never see anything over 91 here in AZ. I've heard there's a station with 93 somewhere around here but I've never seen it.

 

Look at this link, they prove my point exactly,

http://www.ftc.gov/bcp/conline/pubs/autos/octane.htm

" using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner's manual."

That is straight from the federal trade commission

 

says peace to your cats that is if you are runing cats

i run moble 87 every time i fill up i have a moble like two block away from my house so why not just fill up there plus i have one of those speedpass thingys. plus runing a super high octane fuel will take a way all of your upper lubrication form the engine that is why most NASCAR and other racer drivers use a mixture of regular gas and race fuel
