Y33 FELLAS - DON'T BE GREEDY - USE QUALITY FUEL!

[FarFetched]

Remember I had "stumble" at idle in "R" or "D" ?It's gone when I switched form "any" PREMIUM fuel to only one brand CHEVRON SUPREME! Chevron gasoline has given me not only smooth running engine, yet a more responsive car that I relly like/enjoy to drive.I only wish my Old Lady had stiffer suspension (she's getting a bit saggy) Quote »I am being a picky because I drove a Jeep with hard "as a rock" suspension for a long time[/quote]Love your Q and she will return favor! Cheers!

I go no where but BP's. I believe they have Amoco fuel which is by far the best premium fuel. I get more power and MUCH better gas mileage with it.

All fuel is generic. It comes to every gas station the same. The difference is what type of additives the gas station puts into it. So your BP fuel might be great quality, but a station near me could be crap.

not entirely true. There are different qualities. Some places, like BP, Chevron, pick and choose for best quality (cleanliness, energy) and others, like Maverick, take whatever is cheaper.

Add to that the additives used by better stations, who also choose the better gas, and you see a definite difference between good stations and bad ones. It's to the point where Maverick midgrade will ping in my car, while Chevron regular will not.

[PalmerWMD]

Also regional variances play a big role.. in one town they will all be the same except for additives in another they will actually get their stuff from different sources.Its best to check out what works best in your local area.

Up Brand gas stations, are more likely to have better stuff but sometimes its just the same gas (almost)

Fred..

[Q45tech]

Almost none of the marketeers [Brands on the Stations] own refineries any longer! The Feds forced them to divest years ago!

Gasoline produced from the few remaining combinations almost never ends up in their branded stations............the stations are far away UP the pipelines.

[PalmerWMD]

Dont forget the diference in cleanliness of gas storage tanks for different stations..

Yes, very importatnt as well as how often the filter on each pump is changed.

[5seryan]

Q45tch is correct. there hasnt been a refinery built in this country since the 70's. what happens is that oil companies all put their oil into the same oil pipeline. this pipeline is run idependantly from the companies. when a company like Exxon puts in oil and they dont want to wait (which is always the case) they just take out whatever they put in on the other end even though it may have been oil BP put in. There is no way really to choose for best quality, which is the main reason for the addatives in the first place. The others are correct that regional varancies do play a role as well as cleanliness of the storage tanks and the fuel filters.

[Q_SHIP]

I dont have any chevrons in my area.

[Radioaktiv]

so is Shell V-Power not good enough?

I can buy Chevron just as easily...just wondering

[PalmerWMD]

Shell V Power is just fine, likely the same gas in your area as Chevron except for additives

[zinkie13]

I really didn't like V-power when I tried it. I used it for about 2 tanks under normal driving conditions and was really excited to try it. I wasn't satified and actually noticed quite a difference in gas mileage from BP and V-pwr

[MinisterofDOOM]

It's funny hearing this talk about no marketeers owning their own refineries anymore. I drive past at least 5 refineries on the way to and from work every morning. Chevron, Flying J, Foreland, Summit, Silver Eagle, and a few others. Everything here is owned, shipped, and controlled entirely by the companies. Chevron (I use this example so often because A: it's the prominent big-name here, and B: I have family who works in the refinery) does everything in northern Salt Lake, Flying J has their own stuff, does their own refining, and their own shipping. Same with all the others. Nothing is shared, no "pipeline." All independent.

I didn't realize how different that is than most places...

[Q45tech]

New York and rest of NorthEast have no refiners, neither does Florida, South/North Carolina, Maryland and 6 other states. Georgia has 2 small specialty product refineries not for gasoline. Many states have refiners but not for gasoline production........Asphalt, specialty chemicals, etc.

With 18 major and 9 minor specialty gasoline blends to comply with local EPA mandates [individual pollution problems - profiles], the US is a real mess.

I bet sometimes there is not enough of one or more of the 27 possible blends to go amount on any one day.........the tank farms are allowed to substitute for a short period.........within limits.

Distillation Temperatures and Driveability (Distillation) IndexDriveability (or Distillation) Index (DI) is a function of distillation temperatures of gasoline and the oxygen content contributed by alcohols (e.g. ethanol). It is expressed by the formula:

DI = (1.5*T10) + (3.0*T50) + (T90) + (11*OxyA)

where T10, T50 and T90 (in degrees Celsius) are the distillation temperatures where 10%, 50% and 90% of the gasoline is evaporated. OxyA equals the weight percent of oxygen in the fuel contributed by alcohol (ethanol). A factor for MTBE-based oxygen has not been identified, and for the present a factor of 0 is being applied to OxyA for MTBE. 10 volume-percent MTBE equates to 1.8 weight-percent oxygen. 10 volume-percent ethanol equates to 3.7 weight-percent oxygen. It is expected that a factor between 0 and 11 will be developed for the oxygenate MTBE in the future.

Note that Ethanol [%] is multiplied by 11 so it is the major contributer to problems. 105% worse than MTBE of the same percetage by volume.

What amazes me is, that here in California we have the most expensive gas in the nation-don't know about Hawaii and Alaska-and the Worst quality wise.

Can't figure that one out.

[CJQ45]

Dont ask any questions - JUST DO IT.....

Put non-ethanol gas into the car - fill up.Put one can of BG-44k.Put 5oz of pure (high quailty) acetone.

The gas milage on your FY33 will average 26-28 MPG....

Like I said - just do it. DO this for 3-4 tanks. Add BG-44k to the initial tank only. And keep track of your milage.

CJ

[zinkie13]

I am about to do this but I wanted to ask if the acetone can be added past the initial 3-4 tanks. Also, how did you discover this?

[CJQ45]

Once you stop the acetone, the milage will begin to decrease. It needs to be present to get the high milage.

Just today - the gas needle is on 3/4 tank(remaining) line and I have driven the car 168.3 miles!!!! The milage is unbelievable. Its much higher than the stated 18-24 range given by infiniti on the initial car sticker.

[CJQ45]

I just hope the acetone doesn't damage anything like oxygen sensors or injectors....

Q45 tech - any input on this... the milage is great but is it harmful to anything? I know that extended use of methanol could be harmful to oxygen sensors - but IPA will not damage anything. I have not read anything on acetone.

Maybe I should start alternating the acetone to every other gas tank.

[zinkie13]

I did a small amount of research and many people were using it with their gas for hundreds of thousands of miles. Most reported at least a 20% increase in fuel economy. One guy said he got his neon to average 73 mpg on the highway! Thats insane! I think you have to work with your acetone to gas ratio a lot. The suggested range is around 1-4 ounces of acetone per 10 gallons of fuel.

[doc7592]

what is bg-44k

[elwesso]

Hmm i may have to give the acetone trick a try.....

[maxnix]

what is bg-44k

Do a search and see http://www.bgprod.com .

[elwesso]

Tech.... Coudl you chime in on this acetone trick?

[rn240sx]

BP Amoco Ultimate (crystal clear) 93 is my primary choice and Mobil is the secondary choice if BP is not around...

[Yardie_bwoy]

Indeed, I only use Chevron 91 to keep my "Check Engine" light from coming on.

I'm not convinced that Acetone is safe. Can we come to a conclusion on the stuff? Everybody from my egghead friend to those Cartalk guys are saying it's silly.

[Jesda]

Mythbusters did an Acetone test. Failed.

I fill up with BP-Amoco because the nearest BP station is ethanol-free. Qs hate ethanol. Heck, all older Nissans do. I just got done replacing injectors in the Maxima. The Q seems easy by comparison.

there's a really good link. explains A LOT.

edit: i think there's an article about acetone and toulene additives in sport compact car from a while ago, one of the project sr20de sentra ones.
