40 Friction Modifiers In Motorcycle Oil

People have been using car oil in motorcycles with no problems for years. These oils are suitable for use in motorcycles that have catalytic converters in the exhaust system.

The motorcycle oil also has more phosphoruszinc for enhanced wear protection at high engine speeds and high loads.

40 friction modifiers in motorcycle oil. They can also be additives that change the properties of the lubricant itself in order to modify its fluid film to reduce friction. Is a higher standard specification for modern motorcycles. Most modern engine oils will have friction modifiers.

Posted August 7 2007. My issue is that it sounds like it happened to one bike yearmakemodel and so weve been told and preached at to only use engine oils which are free of Friction Modifiers or we will be sorry. For those that dont know SG was teh last of the oil ratings that had high anti scuff additives which is good for older technology engines without roller cams roller cam followers.

Oils that are not friction modified will be rated MA. Though they do share a number of similarities. Behavior mostly depends on the friction modifiers FMs and Anti wear AW additives and therefore has a decisive role to play in reducing friction and wear of moving mechanical components1.

So unlike Mobil 1 for cars Mobil 1 Racing 4T 10W40 motor oil has no friction modifiers which could lead to clutch slippage. Extreme-pressure additives commonly used in gear lubes to protect against shock loads and intense pressures can cause excessive clutch slippage and related damage. Adding friction modifiers to motor oil drwebb Automotive 6 Jun 08 1042 Friction modifiers which can formally reduce _or_ increase friction in terms of engine oil are usually reducers and added for the purpose of improving fuel efficiency as romke points out principally by reducing friction- but not necessarily wear- in the valvetrain at low engine speeds.

So long as you are using an oil made specifically for motorcycles with a JASO certification or even JASO recommendation ie Rotella some other motorcycle specific oils or pretty much any oil without friction modifiers any HDOE or most 10w-40 oil like Mobil 1 10w-40. Truth is as long as it is non energy conserving oil those special friction modifiers in which you spoke of moly btw is not there. The motorcycle oil also has more phosphoruszinc for enhanced wear protection at high engine speeds and high loads.

One of the important class of FMs that are key additives for engine oil performance optimization is organic friction modifiers OFMs2. Because motorcycles normally have a wet clutch system inside the crankcase and such engine oils can decrease the clutch capacity. These oils dont contain any friction modifiers.

Torco oils have a reputation for having HUGE amounts of moly friction modifier in them. All 5w40 5w50 10w40 15w40 15w50 and 20w50 oils which I have found are not energy-conserving and can be recommended for general motorcycle use. I stay away from anything with higher than an SG rating for my bike and I often use that in my car as well.

However engine oils containing friction modifiers can not be applied to 4-stroke motorcycles. Friction modifiers added to some passenger carlight truck motor oils to maximize fuel economy can decrease the coefficient of friction within the clutch pack and result in excessive slippage. It wouldnt hurt out engines i use valvoline duralube 10w40 mostly a blend oil.

However friction modifiers and anti-wear additives are two separate classes of additives. 1979 Honda CB750K 1983 Kawasaki 440LTD and a 1993 Kawasaki Voyager XII 2006 to Present all were modern automotive oils SM or. It is commonly mis-stated that SJ and SL oils have friction modifiers which will cause wet clutch slippage In reality all oils have friction modifiers thats how they work.

Low viscosity oils have poorer film forming properties and so in passenger cars friction modifiers are used to reduce metal-on-metal friction and wear. Friction modifiers for manual transmission motorcycles. That stp is recommended for flat tappet engines and air cooled engines.

In addition Mobil 1 Racing 4T 10W40 has a high performance dispersantdetergent technology for. The motorcycle oil also has more phosphoruszinc for enhanced wear protection at high engine speeds and high loads. In passenger cars low viscosity engine oils are used to provide low drag to improve fuel economy and reduce emissions.

In fact if you would search around you would see that mobil 1 15w50 gold cap and shell rotella T are two of the most popular oils around. There are a few different mechanisms for friction modifiers and anti-wear additives to function. The JASO MAMB system is intended to clear up issues like this.

So unlike Mobil 1 for cars Mobil 1 Racing 4T 10W-40 has no friction modifiers which could lead to clutch slippage. The Influence of Friction Modifiers in Fully Formulated Motorcycle Engine Oils 2018-32-0024 Globally emissions legislation placed on motorcycles is becoming ever more stringent 1. 1 2 Therefore it is important for motorcycle engines to investigate additives which can increase friction.

So unlike Mobil 1 for cars Mobil 1 Racing 4T 10W40 motor oil has no friction modifiers which could lead to clutch slippage. They can be surface active chemicals that bond to react with or form a tribofilm on a surface. OFMs are amphiphilic surfactants.

Ive run the dreaded Friction Modifier oils in three different bikes. Motorcycle oil has more zinc and phosphorus for wear protection and high heat but not the slipperiest friction modifiers. Is a lower standard specification for motorcycles that require different oils for the engine gearbox and clutch.

One way of meeting these new regulations is to use friction modifiers FMs in the engine oil to reduce frictional losses in the engine.
