General Questions |
|
Q. Is the new Series 2000 2-Cycle Racing Oil designed for pre-mix or injector use?
A. It has been formulated for both pre-mix and injector use. |
|
|
Q. What is the mix ratio?
A. AMSOIL has run extensive tests both in-house and with outside laboratories and has determined that the optimum pre-mix ratio is 50:1. If you use any other mix ratio, whether richer or leaner, you will not achieve maximum performance. The 50:1 mix ratio provided lower running temperatures and more power than at 100:1. |

|
Q. Why is the ATC Synthetic 2-Cycle Oil pre-mixed at 100:1 and the Series 2000 is 50:1?
A. One reason is because racing motors are modified from their standard configuration. They are designed to run at higher RPMs, hotter temperatures and more severe conditions. A mix ratio of 50:1 gives that extra added protection needed for racing. |
|
Q. What are the recommended applications for the Series 2000 2-Cycle Racing Oil?
A. Series 2000 Racing Oil is recommended for use in boats, snowmobiles, ATVs, motorcycles and all other applications that demand high performance. It is a top quality product designed for racing and severe service applications, as well as recreational use. |
|
Q. How does the Series 2000 2-Cycle Racing Oil compare with the other AMSOIL 2-cycle oils?
A. AMSOIL Series 2000 2-Cycle Racing Oil is our top performing two-cycle lubricant. It is race-ready and provides more power and cooler operating temperatures than our other two-cycle oils. Basically, these oils’ applications are different. Our 100:1 2-Cycle Oil (ATC) provides top quality, economical performance in pre-mix systems. For customers using ATC at richer mix ratios in racing applications, the Series 2000 Oil is the recommended oil. AMSOIL Injector Oil (AIO) is a performance oil designed for those who want synthetic performance in injector systems, but do not want the price tag or need the all-out race performance designed in the Series 2000 Racing Oil. AIO has earned a reputation for durability and protection and continues to be recommended for recreational and performance injector applications. |

Q. Why is the AMSOIL TCR so clean-burning?
A. It’s clean-burning because of the type of synthetic esters and additives used. The synthetic esters are pure, with inherent solvency characteristics. This means that rather than leave deposits, they have a self-cleaning action to keep the system deposit-free. The other reason it is so clean is that AMSOIL chooses to use ashless technology as opposed to a lot of other companies that use ash-containing formulations. Ash-containing products are dirtier than ashless. This may seem rather obvious, but most companies use ash-containing additives because they are about one-third the cost of ash-less additives. This is true even with competitors’ super premium synthetic products as well as the expensive castor oil two-cycle products. AMSOIL INC. has a lot of history with ashless additive packages. AMSOIL has been using this advanced class of chemistry for many years and has demonstrated excellent performance over time. |
|
Q. What are the specific advantages of using a clean-burning two-cycle oil?
A. The three primary advantages are reduced spark plug fouling, no ring sticking and reduced deposit formation. A fouled spark plug will cause backfires and prevent the motor from running smoothly. Ring sticking from carbon deposits decreases performance and can lead to motor seizure caused from hot gases escaping past the rings and down the side of the piston. Deposits that form in the combustion chamber can cause predetonation because if they get thick enough they can glow red hot which will ignite the gas mixture before the spark plug fires. This creates excessive heat and can burn holes in the piston. Deposits can also clog the exhaust port and limit the action of exhaust power valves found on high performance two-strokes. |
Lubricity |
|
|
Q. What is lubricity and how does it affect a two-cycle engine?
A. The function of lubricity is to reduce friction, increase power and prevent piston scuffing. Piston scuffing increases friction, which reduces power and can result in engine seizure. |
|
Q. What gives the AMSOIL Series 2000 2-Cycle Racing Oil its lubricity?
A. AMSOIL Series 2000 2-Cycle Racing Oil has super lubricity due to its synthetic ester chemistry. The oil has a high molecular weight, which prevents metal-to-metal contact. Generally, high molecular weight petroleum oils burn dirty, but with AMSOIL Synthetic 2-Cycle Oils you get the best of both worlds – great lubricity and clean burning. |
ASTM D-4863 Two-Cycle Lubricity Test |
|
Q. What is the ASTM D-4863 Two-Cycle Lubricity Test displayed on the back of the bottle of AMSOIL Series 2000 2-Cycle Racing Oil'?
A. This ASTM test is a requirement for all TC-W3 and API TC two-cycle oils. This test utilizes a TC-W3 reference oil which all candidate oils are run against. The reference TC-W3 oil is run through a Yamaha CE50S 50cc engine at wide open throttle. The cooling fan is then shut off, allowing the temperature to go up to 350°C. The heat causes the piston to expand inside the cylinder, resulting in an increase in friction and a decrease in torque. The lab then measures the torque value of the reference oil at the elevated temperature (350°C). Then they run the candidate oil through the same procedure and measure its torque value at the same elevated temperature and compare the two results. AMSOIL Series 2000 2-Cycle Racing Oil retained 17.6% more power at 350ºC than the reference TC-W3 oil. The test results are displayed on the back of the TCR bottles. There are two competing oils listed as well. The competitor’s synthetic oil retained only 4.6% as much power and a petroleum oil retained 5.0% power compared to AMSOIL Series 2000 2-Cycle Racing Oil. This test proves that AMSOIL TCR has excellent friction-reducing properties at high temperatures. |
Compatability |
|
Q. Is the AMSOIL Series 2000 2-Cycle Racing Oil compatible with other synthetic and petroleum two-cycle oils?
A. AMSOIL Series 2000 2-Cycle Racing Oil has been tested and found to be compatible with synthetic and petroleum TC-W3 injector oils. Most other oils are also compatible. However, if the oil does not claim TC-W3 performance, there could be compatibility issues. |
Engine Testing |
|
Q. What other engine tests have been performed using AMSOIL Series 2000 2-Cycle Racing Oil?
A. AMSOIL has run inside laboratory tests using a Husqvarna 266 XP chainsaw engine measuring temperature differences with all other top-rated synthetic and petroleum two-cycle racing oils. There were two gasoline-oil mixture lines running to the engine with a simple diverter valve to switch between AMSOIL TCR and each competitor oil. The different oils were then compared while the engine was running so that the exact operating conditions were equal. In almost all cases, as soon as the switch was thrown to supply a competitor’s oil, the temperature would start to rise. AMSOIL Series 2000 2-Cycling racing Oil was found to reduce temperature up to 28ºF compared to competing oils. Some oils experienced a phenomenon called "thermal runaway," which means the temperature was rising to the point of failure if the test had not been halted. The second series of testing was with a Yamaha 338 twin cylinder, twin carburetor snowmobile engine. Each carburetor is fed with a different gasoline oil mixture. This allows you to run one test with two oils under the same conditions. The tests were run under severe conditions of 2 1/2 hours at wide open throttle. This procedure was conducted to measure carbon deposits. AMSOIL Series 2000 2-Cycle Racing Oil produced less deposits than all oils tested. Some oils couldn’t even complete the test due to engine seizure. The test procedure wasn’t even designed to cause this, but rather to see how AMSOIL Series 2000 2-Cycle Racing Oil measured against top synthetic oils in regard to carbon deposits on the cylinder heads, pistons and rings. AMSOIL tested more than 100 different oils. This included different in-house AMSOIL formulations as well as competing oils. Q. Were these tests conducted at independent laboratories as well? A. After the above tests were run in-house at AMSOIL’s laboratory, the testing procedure was repeated at an independent lab to confirm the results. The data obtained for the graph used on the TCR bottle is from the independent lab. Q. Has the AMSOIL Series 2000 2-Cycle Racing Oil been used in actual field trials? A. The development and testing of AMSOIL Series 2000 2-Cycle Racing Oil took 18 months. Variations of the new oil while it was being developed have been run in outboard boat engines and snow-mobiles for field testing as well. The TCR oil is now being used by the AMSOIL Scheuring Speed Sports Race Team during this year’s Snocross Series. In five events so far, the team has captured three first-place finishes, one third-place finish and one fourth-place finish. All events are television on ESPN and ESPN2. |
The Series 2000 Product Line |
|
Q. What qualifies an AMSOIL lubricant to become part of the Series 2000 product line?
A. The Series 2000 line is the next generation of oils resulting from new synthetic technology that has come out in recent years. To put it simply, AMSOIL Series 2000 products are exotic. AMSOIL chooses to stay on the cutting edge of innovation. AMSOIL offers this technology to consumers who want the exotic, best of the best oil. Synthetics have become more popular in the last decade. Every major manufacturer offers some version of synthetic products now. There are also many smaller companies vying for this niche market. AMSOIL wants to be separate from the other synthetic competition and always stay on top. If other companies turn up the level of their oils, AMSOIL will keep staying ahead and always be the best. AMSOIL has selected specific oils that could be justified to be taken to a higher level of technology such as racing applications. These are the Series 2000 products. There are many applications that do not require the ultimate in synthetic technology and not everyone needs the most expensive products that AMSOIL makes, but we have them for those who want the best. There are also selected viscosity levels that meet the requirements to be in the Series 2000 product line so that they would appeal to high-end consumers in those markets. Do not expect to see Series 2000 expand across the board. There is little or no market for a high-performance oil in 10W-40 viscosity weight. |
