Arco Gas - Top Tier?

I hear Arco gas commercials on the radio stating that their gas is Top Tier. Anyone know how it stacks up to other Top Tier gasoline like Shell, Chevron or 76?

i like non-ethanol gas myself although i do run some corn juice through when i have to.

only non-ethanol i can get in my little burg is CITGO and it's 'spensive.

I always avoided CITGO as it provided dear leader Chavez a source of cash. Have not been back since he went to judgement.

Tough to find non ethanol gas in the land of fruits and nuts. 10% here unless its AVGAS. Costco gas is now advertised as top tier. New signage at the pumps.

I use the non alky gas as well especially on my lawn equipment and the motorcycles both of which don't get much use. The S gets it occasionally but I go thru it fast enough that most times I just use premium.

i know about ol' hugo being the CEO of CITGO but the guy that runs the station and the guy that sells the fuel to him both live in my county. i would rather give them my money than some of the other gas station operators here.

i use non-ethanol in my tractor, chain saws, weed eater and lawn mower. just makes life easier.

I heard that too, I guess its time to stop discriminating against ARCO and Costco gas, assuming you ever bought into the "top tier" thing in the first place.

As long as ARCO keeps only taking debit and charging a fee to use my card I will probably keep avoiding it though, on principal.

Go to the light, my son!

I have the AMEX business card through Costco (in addition to the AMEX cash rebate card). Both are free of fees but the business card gets me 5% back on all gas. Helps fight back against the tax and spend folks in our home town. (Funny how they want to raise the gas tax again to pay for road repair when they have been spending the gas tax $ on entitlement programs /education instead of infrastructure the way it was supposed to be done)

I'm sure someone out there has done a test. I've heard about Arco being Top Tier and I've being using Arco for about a year and so far the engine hasn't blown up or pistons stopped moving. I kinda draw the line at Safeway (a California supermarket chain) or Costco. I've read somewhere that gas being delivered to different gas stations comes from the same supplier/truck, just the additive package is different from chain to chain. Not sure how true this is...

Safeway is like Denny's: you only go there if you absolutely have too.
Don't know why you lump Costco in with them. Great business plan, high quality inexpensive merchandise, and the CEO is a super liberal who contributes tons to that agenda.

Especially here on the west coast, we can only refine our gas as no one else wants to follow our goofy and inefficient government imposed method of refining (so called environmental ) gasoline. All the gas comes from a few key refineries. Each brand has its requirements. As each "batch" is created, they simply add each brands requested mix of additives. Away it goes. Techron, dilithium crystals, whatever.

For straight gas, one truck can make several stops if needed. Its all the same.

I lump Costco under the supermarket chain category. At .20 to .25 cents/ gallon cheaper than most, I wonder what additives they're using if any.......plus.... Kirkland gas???

This is what Costco says:

Kirkland Signature™ Gasoline contains five times the EPA detergent requirement in both regular unleaded and premium grades. Kirkland Signature™ Gasoline helps remove any existing deposits and keeps your engine clean.


This is what Top Tier Says:



TOP TIER Detergent Gasoline Retailers

Gasoline retailers must meet the high TOP TIER standards with all grades of gasoline to be approved by the automakers as providing TOP TIER Detergent Gasoline.

In addition, all gasoline outlets carrying the brand of the approved retailer must meet the TOP TIER standards.

Additional gasoline retailers are added to the TOP TIER list as they meet the standards. The retailers known to be on the TOP TIER list are shown below.

TOP TIER Gasoline Retailers:
USA Canada Puerto Rico
76 Stations Chevron Canada Puma Energy Caribe, LLC
Aloha Petroleum CO-OP Shell
ARCO Esso
BP Petro-Canada
Chevron Shell Canada
Conoco Tempo
Costco Wholesale
CountryMark
Entec Stations
Express Convenience Centers
Exxon
Hawaii Fueling Network (HFN)
Holiday Stationstores
Kwik Trip / Kwik Star
MFA Oil Co.
Mobil
Ohana Fuels
Phillips 66
Quik Trip
Road Ranger
Scheirl Oil
Shell
SuperAmerica
Texaco
Tri-Par Oil Co.



op Tier Detergent Gasoline

TOP TIER Detergent Gasoline is the premier standard for gasoline performance. Seven of the world's top automakers, BMW, General Motors, Honda, Toyota, Volkswagen, Mercedes-Benz and Audi recognize that the current EPA minimum detergent requirements do not go far enough to ensure optimal engine performance.

Since the minimum additive performance standards were first established by EPA in 1995, most gasoline marketers have actually reduced the concentration level of detergent additive in their gasoline by up to 50%. As a result, the ability of a vehicle to maintain stringent Tier 2 emission standards have been hampered, leading to engine deposits which can have a big impact on in-use emissions and driver satisfaction.

These automakers have raised the bar. TOP TIER Detergent Gasoline help drivers avoid lower quality gasoline which can leave deposits on critical engine parts, which reduces engine performance. That's something both drivers and automakers want to avoid.

Deposit Control Standards

This technical document describes the deposit control performance of unleaded gasoline at the retail level that minimizes deposits on fuel injectors, intake valves, and combustion chambers. These standards comprise the requirements for TOP TIER Detergent Gasoline.

Standards

1.1 Retail Gasoline Performance Standards. The deposit control performance of unleaded gasoline conforming to section 1 of this document shall be met at the retail level in all grades of gasoline sold by a fuel company in all marketing areas of a selected nation. In addition, conformance to the standards shall mean gasoline sold in the selected nation shall not contain metallic additives, including methylcyclopentadienyl manganese tricarbonyl (MMT).

1.2 Deposit Control Additive Requirements. The deposit control additive used to meet the performance Standards described in 1.3 shall meet the substantially similar definition under Section 211(f) of the Clean Air Act. Also, the additive shall be certified to have met the minimum deposit control requirements established by the U.S. Environmental Protection Agency (EPA) in 40 CFR Part 80. Lastly, the additive shall be registered with the EPA in accordance with 40 CFR Part 79.

1.3 Deposit Control Initial Performance Standards. Initial deposit control performance shall be demonstrated using the tests shown below.

1.3.1 Intake Valve Keep Clean Performance Standard.

1.3.1.1 Test Method. Intake valve deposit (IVD) keep clean performance shall be demonstrated using ASTM D 6201, Standard Test Method for Dynamometer Evaluation of Unleaded Spark-lgnition Engine Fuel for Intake Valve Deposit Formation. Tests demonstrating base fuel minimum deposit level (1.3.1.2) and additive performance (1.3.1.3) shall be conducted using the same engine block and cylinder head. All results shall be derived from operationally valid tests in accordance with the test validation criteria of ASTM D 6201. IVD results shall be reported for individual valves and as an average of all valves.

1.3.1.2 Base Fuel. The base fuel shall conform to ASTM D 4814 and shall contain commercial fuel grade ethanol conforming to ASTM D 4806. All gasoline blend stocks used to formulate the base fuel shall be representative of normal U.S. refinery operations and shall be derived from conversion units downstream of distillation. Butanes and pentanes are allowed for vapor pressure adjustment. The use of chemical streams is prohibited. The base fuel shall have the following specific properties after the addition of ethanol:

Contain enough denatured ethanol such that the actual ethanol content is no less than 8.0 and no more than 10.0 volume percent.
Contain no less than 8 volume percent olefins. At least 75% of the olefins shall be derived from FCC gasoline as defined by CARB (advisory letter, April 19, 2001).
Contain no less than 28 volume percent aromatics as measured by ASTM D 1319 or D 5580.
Contain no less than 24 mg/kg sulfur as measured by ASTM D 2622 or D 5453. At least 60% of the sulfur shall be derived from FCC blend stock.
Produce a 90% evaporation distillation temperature no less than 290F. as measured by ASTM D 86.
Produce IVD no less than 500 mg averaged over all intake valves.
1.3.1.3 Demonstration of Performance. The base fuel from 1.3.1.2 shall contain enough deposit control additive such the IVD is no more than 50 mg averaged over all intake valves. Results for individual valves and an average shall be reported. The unwashed gum level of the fuel containing deposit control additive shall be determined according to ASTM D 381 and reported.

1.3.2 Combustion Chamber Deposit Performance Standard.


1.3.2.3 Demonstration of Performance. The base fuel from 1.3.1.2 treated with additive at the concentration meeting the standard found in 1.3.1.3 shall not result in more than 140% of the average CCD weight for the base fuel without additive.

1.3.3 Fuel Injector Fouling Performance Standard.

1.3.3.1 Test Method. Fuel injector fouling shall be measured using the TOP TIER fuel injector fouling vehicle test available from GM. GM will run the test on a first-come-first-served basis and shall make the method available to those who wish to run the test on their own.

1.3.3.2 Base Fuel. Two options for base fuel are available:

1.3.3.2.1 Option 1. A full boiling range hydrocarbon gasoline or gasoline blending component, without oxygenates and without deposit control additives, that results in at least five inoperative injectors when tested by the method in 1.3.3.1.

1.3.3.2.2 Option 2. Federal emissions test gasoline specified in DFR 86.113-04, into which 4-methylbenzenethiol (WARNING: Flammable solid; irritant) has been blended at a concentration of 56 mg/L. The blended fuel must result in at least four inoperative injectors when tested by the method in 1.3.3.1. the Federal emissions gasoline, without deposit control additives, available from
Haltermann Solutions
15635 Jacintoport Blvd.
Stolt Building, Second Floor
Houston, TX 77015
800-696-2542
www.haltermannsolutions.com
1.3.3.3 Demonstration of Performance. A demonstration of injector fouling shall be done first. At least five out of six injectors (with Option 1) or at least four out of six injectors (with Option 2) shall be inoperative for the test to be valid. A demonstration of additive performance shall be done after the fouling tendency demonstration; no other test shall be conducted on the vehicle in the interim. A demonstration of additive performance shall be conducted using the same vehicle (including the fuel drain and flush procedures and installing new injectors) with the same batch of base fuel, but now containing the same amount of deposit control additive as in 1.3.1.3. A pass is defined as no more than one inoperative injector.

1.3.4 Determination of Deposit Control Additive Performance Concentration.

1.3.4.1 Methodology. The concentration of deposit control additive needed to meet the standards in 1.3.1.3 and 1.3.3.3 should be equivalent. However, if the concentration of deposit control additive in 1.3.3.3 is grater than in 1.3.1.3m the higher value shall be regarded as meeting both standards. Also, if the difference between the two concentrations is grater than 15%, 1.3.2.3 shall be repeated using the higher concentration.

1.3.5 Intake Valve Sticking Performance Standard.

1.3.5.1 Test Method. Intake valve sticking tendency shall be determined using either the 1.9 L Volkswagen engine (Wasserboxer according to CEC F-16-T-96) or the 5.0 L 1990-95 General Motors V-8 engine (SWRI IVS test). Two options are available for demonstrating intake valve sticking tendency.

I had to chop out a bit to make it fit in the post.


Yep, Kirkland. That is why I have always made $ on Costco stock!
