Shell V-Power

[skiiirt]

Has anyone seen this before? It supposidly "actively cleans your injectors and intake valves"

 

I only use shell gasoline in my car as it is. I hope they arent bullshitting us

Shell V-Power

 

which leads me to my next question. where do you get your gasoline?

I only fill up at shell

[93CutlassSupreme]

heard about it

 

all the shells around here are advertising it

 

i use BP/Amoco, and Mobil.

 

won't ever use Speedway, every car i've ever driven that has had speedway gas has sparked knocked like a mo fo.

 

speedway gas even plugged up one of my fuel injectors 6 or 7 years ago, before i owned the car

[GutlessSupreme]

I haven't looked into it but from what it seems like, it's just regular old 93 octane with a fancy name and advertising to try and make it sell better.

 

I hate Shell. Too damn expensive. I've been going to my local middle eastern operated Getty station.. 5 cents off all grades on Monday. $1.86 for regular (on Monday)

[excelsior]

my cars have always done well on shell....and having a car that must take premium 93 octane helps....although i usually just go to whatever is the closest when i need gas.

[Guest TurboSedan]

Exxon 85 for my Cutlass, and Exxon 91 for my GTS.

[sl3196]

I use shell 91 (v power) or exxon 91. No differance between the too. Even used conoco before and no differance. Only place I really won't go is maverick after rumors of them watering down the gas.

Funny thing about gasoline - you can't add water to it, it'll sepperate the addatives very quickly.

 

did you know that government regulations require that all gasoline contain basically the same amount of additives to clean the injectors, valves and combustion chambers?

 

anyhow, of all the gasoline you buy, nearly all of it is about 30% addatives to bring up the antiknock quality (higher octane rating) and detergents for that cleaning and such ... enough of my babbeling - here's a good little article on how horrable modern engines/gasoline additives are.

 

Tetraethyl lead additives in fuel weren't regarded as a public health issue for over forty years since their widespread introduction. Following Harry Ricardo's pioneering work, this additive was shown to greatly reduce engine wear as well as functioning effectively as an anti-knock compound. There was a controversy, at first, but the major companies carefully deleted the term 'lead' from the additive's name, and called it 'ethyl' instead. The use of this additive allowed higher compression ratios, improved power and efficiency. After a while with nothing going obviously wrong, the fuss died down.

 

It came as a surprise to the motoring public to find that their (our?) exhaust emissions were being linked to lead poisoning in city populations. Unleaded fuel, together with catalytic converters, was presented as a 'pure', clean, simple way to solve the problem.

 

Unleaded fuel is not pure petrol. Additives are used in order to make sure that the fuel will not detonate prematurely in modern high-compression poppet-valve engines. The octane rating of a fuel does not measure the power of that fuel. It only measures how far a fuel-air mixture can be compressed in a hot, running engine, before detonation begins. As discussed in the site, the exhaust poppet valve glows red-hot while in use, making it difficult to squash a fuel-air mixture against it without uncontrolled ignition.

 

It is widely known that catalytic converters will not work until they are warmed up, i.e., for the first ten minutes of a car trip, the converter will not be cleaning the exhaust. The converter will 'wear out' with age and need replacement. What is less widely known is that the reactions inside a catalytic converter are not fully understood, particularly as the converter ages with the car. What comes out of the converter is not fully known either, and there is speculation that small amounts of hydrogen sulphide gas are generated. Hydrogen sulphide is a heavy gas, originally used as a nerve gas in World War I.

 

The additives in unleaded petrol themselves are the subjects of debate, since one of the principle additives is usually benzene. This is a chemical that has been known to be carcinogenic for over forty years. It is accompanied by a number of other chemicals, some of which carry similar risks. The proportions of the additives are high: approximately twenty percent, by volume.

 

A portion of the benzene (plus toluene and others) escapes combustion and is released to the air via the exhaust pipe. The catalytic converter will not trap this, or render it safe by converting it into another chemical compound such as water.

 

I accept that this is vague. Ask yourself this: When the unleaded fuel was being introduced and the very expensive public opinion advertising campaigns were mounted, were the oil companies at pains to list the additives and to point out that these were safe? Or did they not mention the word 'additives' at all?

 

I'm not qualified to enter the leaded vs unleaded debate more fully, but I think that the better solution is to have an engine that does not require any kind of additives in its fuel. Such an engine is presented here on this site - the Aspin engine was noted for its immunity to knock. Unfortunately, poppet-valve piston engines are restricted to a compression ratio of only 4 or 5 with pure petrol running, so using existing and accepted technology would require huge increases in fuel consumption and thus increased amounts of exhaust gas. Introducing a new engine type globally requires convincing roughly 2 billion consumers that it is an idea in their best interests, especially difficult when most consumers have been taught from birth to be conservative.

 

anyhow, I fill up at any gas station with the lowest price - my car loves all of 'em... altho my mustang hates anything other then 110 octane leaded gasoline - $3.99 per gallon - I'm not really offended by the near $2.00 gallon cost right now it's still half of what I pay for my 'stang.

I'll use pretty much anything in my car. The only stuff I avoid is Speedway gas since it contains 10% ethanol in our area which leads to noticably worse gas mileage.

yeah, Speedway is crap.

 

it fucks up fuel injectors too.

[PeNZ]

We have that 10% ethanol bullshit in all our gas here in S.E. Wisconsin, damn emissions laws.

Casey's or Breaktime(MFA OIL) here. Super unleaded (89) is the same price as 87 octane. I feed my beast the cheap stuff and it seems to like it. I like to run a bottle of Lucas injection cleaner thru it every other fill up.
