Arco gas? (2025 Update)

Jul 22, 2007 Last reply: 8 months ago 85 Replies

Shell 93 doesn't have any more DETERGENTS than any other grade. Its just a higher octane. And as far as detergent effectiveness, Shell is (at best) second or third in rank. Chevron is definitely better.

I know this much for certain.There is an Exxon gas station near me.More than more than a few years ago, I used to buy gas there for my 1978 Dodge van.It got to where my van was running lousey.I looked inside of the carburetor.There was some blush greenish mossy looking stuff inside of the carburetor.Every since then, I stay far away from Exxon (Chevron too) gas and I have no more problems concerning gasoline.I won't even buy those brand names of gas for my little walk behind lawn mower. cuhulin

No, Shell's 93 does in fact have more detergents than their other grades.

It isn't about the miles per gallon; it's all about the cents per mile.

You have to normalize using that method, because of fluctuations in gas prices among brands. One brand may be more expensive to buy, but it may or may not be more expensive to run.

Why buy Arco and give Hugo Chavez more profit?

Don't buy Exxon and, or, Chevron gas, and you should be OK. cuhulin

Maybe because you're confusing Citgo with Arco?

:-)

No, premium means higher octane, meaning more of the components that slow down the burn and avoid pinging. Some engines run better on higher octane, and some get higher mileage. Some don't. I was trying to figure out if mine did.

It's your mind, fool.

Here's an idea: have someone else fill up the car, but don't tell you what's in it.

You have fooled yourself into believing that "premium gas" equals "better" and so you THINK the car "feels slightly better".

You, sir, are a fuel marketer's dream customer.

You, sir, are a monumental asshole. I'd much prefer it if regular felt better, because I do indeed run the car on regular.

Can you quote me somewhere that says that?

How about this:

Quote:

"Shell regular and mid-grade gasolines contain more than twice the amount of detergents required by the EPA. This level of protection helps prevent the future build-up of carbon deposits on your vehicle's intake valves or fuel injectors. However, if you use discount gasolines, you may already have intake valve or fuel injector deposits, which may need to be cleaned up. That is where Shell V-Power(R) comes in...."

"On today's tough, demanding roads, performance is what counts. At Shell, we believe all great performances begin with a clean engine. Shell V-Power(R) premium gasoline can clean up deposits on intake valves and fuel injectors left behind by low detergent gasolines. That's because it contains more than five times the amount of cleaning agents required by government standards...."

So Shell's Top Tier fuels contain "more than twice the amount of detergents" required by law while their V-Power--which, unfortunately, comes only in 90-93 octane depending on where you live--contains "more than five times the amount of cleaning agents" required by law.

So the fact is, you can't provide a link or ANYTHING from Shell that says, "same great cleaning in all gasoline grades".

I can top that!

A few months ago when fuel prices were very high I was filling up and an acquaintence pulls into the station. We exchanged comments about the prices and he says that it's especially bad because he had to fill with premium this time. I asked why and he said that he had a smog test scheduled in a few days and the premium would help ensure passing the test! I just turned back to my task without saying a word.

knock sensors are generaly there to retard ignition in the event that a premium tuned car is filled with regular. protection the other way around is not required, so what you're experiencing is probably ignition that's /too/ retarded relative to the gasoline combustion rates, hence smoother [lower yield] power strokes. and lower gas mileage.

Oops! My bad

The signs on the pumps in Shell stations frequently said that up until their most recent ad campaign. I think some marketeer decided to insinuate a difference between premium and regular/mid-grade with the latest campaign.

Nor can you find anything that QUANTIFIES any difference between Shell regular and premium detergent percentages. In case you didn't notice "more than twice" and "more than five times" are hardly quantitative, and since "more than five times" is actually a subset of "more than twice," it doesn't even prove that there's a difference other than marketing!!!

I've used Shell gas for some time now, and every collateral on top of every pump has extolled the difference in detergents with their 'v-power'.

I've never seen anything from Shell indicating "all grades, same cleaners!".

Sure. More than 2x what the law specifies for their non-v-power stuff, and more than 5x what the law specifies for v-power.

It starts with what the law says. The law quantifies it for you.

Well, if you read it in context, it's plain what they're saying.

A divorced woman who works for AT&T used to live next door to me.She sold that house (next door to me) to her very skinny twin sister.Skinny twin sister works on an off shore Shell (Ram Powell off shore oil rig) oil rig about eighty miles South of Mobile,Alabama.Two weeks on, two weeks off.She is due to show up next door to me sometime or aother this coming Friday, or whenever.That gal is soooo skinnyyyyy, if she turned sideways, she would disappear. cuhulin

er, why don't /you/ do some homework for a change? all you're doing here is pissing and moaning, but i don't see you contributing a damned thing. go figure out what the detergents are and the legal minimum. then report back with your findings.

The law quantifies only the minimum. "More than " is NOT quantitative.

And I'm not sure I even believe that the law PLACES a minimum on detergent content, come to think of it!

Its plain what you are BELIEVING, not what they are saying.

If both grades contain 6x the "minium required", then BOTH statements ("regular contains more than twice," "premium contains more than 5x") are QUITE true. And also QUITE irrelevant.
