It's long been known that many successful Amsoil dealers started out as Preferred Customers. People start out as PC's because they want to use superior products and save money doing it. Once they see how awesome the products are, and see what a great company Amsoil is, and see that an Amsoil dealership can be a real business that costs almost nothing to get started, they're hooked. One such Preferred Customer is Marty Gregor of St. Petersburg, Florida. Marty recently contacted me and told me he wanted to upgrade his PC membership to a full dealership. I'm really looking forward to helping Marty get started with his business.

If you are thinking about getting started with a home-based business, there are few opportunities better than Amsoil. If you already use and believe in the products, you're halfway there.

New low-emission engine models with high rates of exhaust gas recirculation have inherent lubricant challenges. These engines dump excessive amounts of soot and acids into an oil, accelerating wear on the cylinder walls. Additionally, new engine oils meeting CJ-4 requirements will have lower sulfated ash content, which controls TBN levels. The new mandate only allows enough sulfated ash content to reach a maximum TBN of eight, making TBN retention even more important. New AMSOIL Diesel Concentrate controls these issues by neutralizing acids during combustion. This minimizes acidic cylinder wear and reduces the rate of engine oil TBN depletion, maintaining engine oil quality longer for better protection.

1. Question:
Why did AMSOIL separate the cold flow properties from the Diesel Concentrate (ADF)?
Answer : Combining AMSOIL Diesel Concentrate with a Cold Flow Improver is not cost effective in the summer months, or to AMSOIL customers who live in the south. To keep costs down for customers, AMSOIL Diesel Concentrate no longer includes a cold flow improver. AMSOIL Diesel Concentrate has been reformulated with additional lubricity properties. The new AMSOIL Diesel Concentrate (ADF) is a total system cleaner and lubricity improver for all types of diesel engines.

2. Question:
Does the new AMSOIL Diesel Concentrate meet the federal regulations for ultra low sulfur for diesel fuel?
Answer: Yes, and the packaging label states so as regulated by law.

3. Question:
The old Diesel Concentrate worked well. Why did AMSOIL come out with a new Diesel Concentrate?
Answer: The federal government mandated the use of ultra low sulfur diesel (ULSD) by June 2006 for the year 2007. ULSD contains <15 parts per million (ppm) sulfur where the previous content was <500 ppm sulfur. Sulfur acts as a lubricity agent that helps protect pumps and injectors from wear. As the sulfur content is lowered, so is the lubricity of the fuel. As a result of lower sulfur content, refiners or fuel distribution depots have been forced to add back some lubricity with the use of additives. This additive is expensive and is only blended in the fuel at the lowest additive concentration (LAC). The fuel manufacturers have no incentive to add extra additive, which increases costs, so there is inherent risk of unnecessary wear on injectors and pumps. The new AMSOIL Diesel Concentrate Additive adds back all the lubricity and then some to properly protect diesel fuel components.
ULSD fuel has also shown to create more deposits within combustion chambers than previous diesel fuels. Deposits are detrimental to fuel economy, throttle response, and horsepower. AMSOIL Diesel Concentrate is a powerful detergent that cleans fuel system deposits and keeps the system clean with regular use. By cleaning deposits, AMSOIL Diesel Concentrate has shown to increase fuel mileage up to 5%. Consider that at $3.00 per gallon for diesel fuel, even a modest three percent improvement in fuel economy equals a savings of $0.09 per gallon. With a treat rate of one oz. of AMSOIL Diesel Concentrate to five gallons of fuel, at U.S. Dealer prices, the net treat cost of AMSOIL ADF is $0.06 per gallon, bringing the total savings to $0.03 per gallon and negating the cost of AMSOIL Diesel Concentrate altogether.
AMSOIL Diesel Concentrate is an alcohol-free product that also protects fuel systems against water contamination. It helps prevent fuel/water emulsions and it protects metal against rust. Water can be drained easier and fuel filters are less likely to plug, ensuring drivability. In addition, fuel degradation can cause gums, which increase deposits and the chance of filter plugging. AMSOIL Diesel Concentrate significantly improves the oxidation and thermal stability of diesel fuel. These are some key advantages of the new Diesel Concentrate among others identified on the data sheet (G-2236). Diesel equipment is expensive and owner/operators prefer to control the quality of the diesel fuel going into their engines rather than rely on the fuel producers. AMSOIL Diesel Concentrate provides outstanding performance in today’s ULSD fuel as well as the former 500 ppm version fuel and biodiesel.

4. Question:
The claims state that the new Diesel Concentrate helps engine oil maintain TBN. How does it do this?
Answer: TBN depletion is the result of combustion acids. AMSOIL Diesel Concentrate is designed to neutralize acids during combustion to prevent the acids from attacking the TBN reserve in the engine oil. Additionally, acids from combustion cause acidic cylinder wear. By neutralizing acids during combustion, AMSOIL Diesel Concentrate helps control acidic cylinder wear.
These features are particularly important on exhaust gas recirculation (EGR) equipped engines (2002 and newer). By recirculating the exhaust back into the combustion chamber, more acids are introduced, wear increases, and TBN is rapidly depleted. For model year 2007 vehicles, the amount of EGR is being further increased compounding the problem.

5. Question:
Will using ADF void engine warranties?
Answer: No.

Last month I told you all about my 1994 Mazda Miata. This time I'll tell you a little about my 2000 Corvette. It's got right at 100,000 miles on it and runs and looks like new. For the first few years of its life it was fed a steady diet of Mobil 1, because that's what it says to use right on the oil filler cap. Never one to just blindly follow directions, after I discovered Amsoil, I immediately wanted to use it in the Vette. The reality of the Vette is that you DON'T have to use Mobil 1. What you DO have to use is a synthetic oil that meets the GM 4718M standard. This standard was developed by GM to ensure that the Corvette's LS-1 engine (and later variants) received an oil that met its unique requirements. It just so turns out that AMSOIL ASL 5W-30, ATM 10W-30, and Series 2000 0W-30 are certified to meet the GM 4718M standard. No non- synthetic oils meet this standard and a LOT of synthetic oils don't meet it either. In fact not all Mobil 1 oils meet the standard. Their extended- mileage oil doesn't! So rather than blindly follow orders, I use ASL in my Vette. It costs about the same as regular Mobil 1, but beats it in performance tests. Anyway, we love the Vette and will probably upgrade to a C6 model within the next couple years.
