I know! Oh No! Here's the oil study again. No really just thought I would pass on some information. I have a rocket with an aerocharger turbo. I decided to go with 20-50w amsoil oil due to the extra stress of the turbo and the mild climate I tend to operate my bike in. My exhaust headers glow red under acceleration, and they always have. Call me crazy, call me lean, but I swear I have more throttle response. And the sound of the exhaust has more of a growl to it. Similar to when I run in cold weather. The turbo loves cold air and it is noticeable. Maybe it's an illusion, but it sure feels more responsive and gear changes seem smoother with less noise.

Amsoil sent me some information when I discussed my situation with one of their rep's, Here it is if your interested:

Dear steve,

Ok, today I would like to focus on three of the most popular AMSOIL synthetic oil products for gasoline engines: the 10W-30 and 5W-30 synthetic motor oils and the 0W-30 Severe Service synthetic motor oil. I will review each without going into complicated technical descriptions so you have the correct information to know what to use in your vehicles and/or recommend for your customers.

If you would like a copy of the detailed product specification and ASTM test results please respond to this e-mail and I will send them to you right away.

Before we get started let me explain the basics of viscosity and oil nomenclature: For example a 10W-30, 5W-30 and 0W-30 oil are all 30 weight oils. The differences occur in that the 10W, 5W and 0W each is a little bit different in cold weather (W stands for weight in winter weather). The 10W-30 acts like a 10 weight oil in winter weather until it warms up and then it is a 30 weight oil. The 5W-30 oil acts like a
5 weight oil in winter weather and when it warms up is a 30 weight oil. Same theory holds true for the 0W-30 oil. The differences are ever so slight that you would not be able to differentiate which one was in your engine without the use of specialized engine testing equipment. In fact 5W, 10W and 0W are strictly empirical numbers. In order to discern the differences one needs to review the kinematic viscosity of each lubricant. Kinematic viscosity is measured in Centistokes and is essentially the amount of time, in Centistokes, it takes a lubricant to flow through a fixed orifice at both 100 deg. Celcius and 40 deg. Celcius. For example, the kinematic viscosity, at 40 deg. C or AMSOIL 5W- 30 is 59.5, AMSOIL 10W-30 is 66.1 and AMSOIL 0W-30 is 57.3.
So as you can see the values are extremely close to each other.

In respect to the 5W-30 vs. the 10W-30 there are virtually no major differences other than the 10W-30 is formulated for turbocharged engines. Therefore when you use it in a non- turbocharged engine you get that extra measure of protection. The 5W-30 is often used by those customers that go exactly by the book and will only use what their owners manual says. Even though the price is the same I always attempt to sell them on the superiority of the 10W-30.

I usually recommend the AMSOIL 5W-30, 10W-30 or 0W-30 even when the manufacturers recommendations call for a 5W-20. You see, I am a recently retired engineer from one of these automotive manufacturers here in Detroit, MI and I will let you in on a little secret: the auto manufacturers like to use lighter viscosity motor oils so that the vehicles get better CAFE (Corporate Average Fuel Economy). Vehicles and components are also engineered to have a finite life within certain durability mileage ranges and test cycles and are tested using the petroleum oil that is specificed by the manufacturer.

CAFE is mandated by the Federal Government and it is the average fuel economy of the entire vehicle line a manufacturer produces. Big trucks and SUV's are highly profitable where small cars are not nearly as profitable, so in order to get the CAFE #'s reported to the Federal Government higher and be able to sell more SUV's and trucks they use lighter viscosity oils to compensate like a 5W-30 or 5W-20 so fuel economy increases (only in controlled tests which is why you'll not notice a difference in your vehicle). If you would like a more detailed explanation of this you can refer to my website and click on the "Ford and Honda's 5W-20" link. I have provided a link to my website at the end of this note. If you still just have to use 5W-20, then AMSOIL does manufacture an excellent 5W-20 which far exceeds any OEM manufacturers specifications as well as outperforms them all in the 4-ball wear test, it is a 7,500 mile/6-month oil or longer if your vehicle has an oil life monitoring system. Note that AMSOIL's 0W-30 is a 35,000 mile/1-year oil and the AMSOIL 5W-30 (ASL product code) and 10W-30 (ATM product code) are both 25,000 mile/1-year oils.

In addition, when these CAFE tests are run they are run under strictly controlled conditions on a closed course test track and with specially tested lubricants and fuels which are all within specifications. In fact, they don't even use standard pump grade fuel like is sold at retail gas stations. They use Indoline, a reference test fuel. That could possibly be one reason why your vehicle may not achieve the fuel economy numbers stated on the window sticker.

It is my opinion that the auto manufacturers are looking out for their best interests, profits and repeat business when vehicles need to be replaced. It is my opinion that they figure if you get a decent average service life out of your engine and powertrain without any major problems then you will be satisfied and will trade it in or sell it and buy another one soon. If they manufactured a vehicle that was so durable that you didn't need to buy a new one very often new vehicle sales would decrease significantly. AMSOIL has been proven to reduce wear. With AMSOIL you will exceed normal mileage values and your vehicle(s) will be better protected, last longer and provide superior performance and you will realize improved fuel economy and save time and money in the process.

I have both new model diesel and gas engine vehicles as well as older vehicles. My older trucks are 1987's and still in immaculate mechanical condition which I attribute to AMSOIL Synthetic Oil in the engine, transmission, transfer cases and differentials as well as AMSOIL Dual-Remote By-Pass Oil Filtration Systems and AMSOIL Absolute Efficiency Oil Filters.

Also, I will explain that any Series 2000 or Series 3000 product AMSOIL manufactures is the best of the best. It is AMSOIL's super premium product, usually rated for extreme Severe Service and/or racing applications, but can be used in any application such as everyday driving, racing, severe service or other demanding applications.

AMSOIL's Series 2000 0W-30 Synthetic motor oil is based off the chemestry from AMSOIL's racing oil. The product code is
TSO-O1 for a case of quarts or TSO-QT for individual quarts.
It outperforms every other synthetic and petroleum oil on the market, including Castrol and Mobil1 5W-50 weight oils!
The 0W-30 Series 2000 is a 35,000 mile/1-year motor oil.
That means you can leave it in your enigne for 35,000 miles or 1-year, whichever comes first. If you haven't put 35,000 miles on in 1-year then I recommend performing oil analysis testing prior to continued use, or just change your oil once a year. Pretty simple and easy to remember. The AMSOIL Absolute Efficiency Oil Filters are specified as 25,000 mile/1-year change interval. With this oil you will notice improved fuel economy due to reduced friction and increased performance and smoother operation. Although I do not like to quote mileage improvements because they vary for each vehicle, recently my Dad changed to the 0W-30 in his 2000 Ford Econoline with the 4.6L Triton engine and gained approximately 1.5 miles per gallon improvement. These kind of figures are very common with the 0W-30. I have several other customers that report similar improvements. I always recommend the Series 2000 0W-30. If the customer is extremely conservative and cost conscious or has a higher mileage vehicle then I sell them the standard AMSOIL 10W-30 or 5W-30.

The 10W-30 product code is ATM-01 for a case of 12 and ATM- QT for individual quarts. The 10W-30 synthetic oil is a 25,000 mile/1-year motor oil. The 10W-30 is a very good oil for all gasoline engines. You should also notice a fuel economy and performance improvement with the AMSOIL 10W-30 as well.

The performance and fuel economy improvements usually do not happen instantly. You need to drive the vehicle to allow the detergents in the AMSOIL to clean the petroleum oil deposits from the microscopic valleys in the steel and aluminum of your internal engine components. As it cleans the deposits out, AMSOIL molecules which are uniform in size and shape, and do not change size or shape with extreme heat or cold, will fill those valleys which will provide for a uniform layer of AMSOIL synthetic oil molecular chemistry on the surface layers of your engines internal components. That is why you will notice smoother, more responsive operation and a fuel economy improvement. If you have an engine with more than about 20-30,000 miles I recommend you use a can of AMSOIL engine flush prior to changing over to AMSOIL in order to clean out the increased amount of petroleum depostis which are present in higher mileage engines.

I hope this brief explanation helped you understand what is happening in your engine with AMSOIL. I tried to explain a highly complex chemical and mechanical process in a way that everyone can understand.

That's all for this e-mail. In future e-mails I will cover many more important aspects of the various AMSOIL products and their applications as well as other lubrication, filtration and business information.

I would like end this e-mail by letting you know what a truly wonderful company AMSOIL is. I cannot say enough positive things about the company and the products and also the business opportunity offered to each and every Dealer.
In my next e-mail I will share a note from Al Amatuzio, President and CEO of AMSOIL. After reading the note you will know exactly why AMSOIL makes the best lubricants in the world, right from the man that started it all back in 1972.
I am very proud to be associated with such a quality company and am confident you would be also, should you choose to become a Dealer.

Best regards, steve,
