AMSOIL has released a brand new synthetic oil series designed specifically for 4-stroke dirt bikes. AMSOIL Synthetic Dirt Bike Oils are now available in 10W-40, 10W-50 and 10W-60. These motorcycle oils are designed to withstand the abuse inflicted upon dirt bikes and are suitable for everyone from world-class motocross racers to casual trail riders. These oils deliver AMSOIL’s famous synthetic protection of 4-stroke engines, gears and clutches, buttery smooth shifting and maximum clutch conservation.
Frequently Asked Questions About AMSOIL Synthetic Dirt Bike Oils
Question: AMSOIL already offers their Advanced Synthetic Motorcycle Oil 10W-40. What is different about this new Dirt Bike 10W-40 Synthetic?
The new AMSOIL Dirt Bike 10W-40 formula places more emphasis on clutch preservation. Dirt Bike clutches can be subject to tremendous abuse. Many MX riders use persistent clutch slippage to moderate traction and maintain speed through corners. Hard riding through deep mud and sand can fry a clutch in mere minutes. One of the primary goals of these products is to dissipate heat in clutches and maintain its frictional properties to prevent slippage. Maximum power output and consistent clutch-lever feedback is the result.
Question: Does the introduction of AMSOIL Dirt Bike Oil imply that their current Advanced Synthetic Motorcycle Oils are insufficient for off-road use?
Not at all. As AMSOIL was adding 10W-50 and 10W-60 Dirt Bike Oils, it only made sense to include a Dirt Bike 10W-40 so that they could offer a full suite of oils for off-road motorcycles. The current AMSOIL 10W-40 Synthetic Motorcycle Oil has been used in professional motocross competition for years with outstanding results. Marcel Irnie (who happens to be one of North America’s fastest pro road racers) has told us that he can get a full season out of a set of clutch plates using the current AMSOIL Advanced Synthetic Motorcycle 10W-40. If you know anything about AMSOIL, it’s no surprise that they are always looking for a ways to raise the bar. So the release of this Dirt Bike 10W-40 is in no way an indictment of the current Advanced Synthetic Motorcycle 10W-40 Oil or its prowess in off-road applications.
Question: Can I use AMSOIL Dirt Bike Oils in my street bike?
Absolutely. AMSOIL Dirt Bike Oils can be used in any street bike, road racer, supermoto, scooter or ATV that calls for 10W-40, 10W-50 or 10W-60 4-stroke oil. These oils meet or exceed the JASO MA, API SG, SJ, SH, SL specifications.
Question: What is drain interval for AMSOIL Synthetic Dirt Bike Oils?
AMSOIL Synthetic Dirt Bike Oils should be changed at the interval suggested by the motorcycle manufacturer.
Question: Are these Dirt Bike Oils suitable for use in two-stroke motorcycle transmissions?
Yes. These oils are designed for maximum transmission and wet-clutch protection, so they are optimum for this application.
Question: Can AMSOIL Dirt Bike Oil actually improve the performance of my motorcycle?
Yes and on a number of fronts. 1. The 100% synthetic formula reduces friction in your engine, so it can operate at peak output. 2. Shifting is improved, even under heavy loads. 3. As mentioned, this oil is designed to keep clutch plates from expanding due to heat and slipping, so power is put to the ground and not compromised due to clutch slippage.
Question: Is this the same motorcycle oil used by the Geico Honda Pro Motocross team?
Yes. AMSOIL has always had a policy of providing the same oils to their sponsored professional race teams that you and I can buy. MX superstar Eli Tomac and the rest of the Geico Honda team were instrumental in the development of this Synthetic Dirt Bike Oil formula.
Question: What container sizes are offered for AMSOIL Synthetic Dirt Bike Oils?
These oils are available in single US quarts (946 ml) or in cases of 12 US quarts.
