1. Only oil weights xxW-30 and down are required to have friction modifiers in order to meet the current API/ILSAC specs. 2. SE and SF are indeed obsolete specifications. The motorcycle industry is pathetically clinging to these deprecated standards for a lack of anything truly better. The reason? In theory, SE and SF both allow for a higher level of EP (extreme pressure) lubricants (such as zinc/phosphorus) than do the newer specs. Notice that I didn't say that these specs "call for" or "require" higher EP levels. Only that they ALLOW for a higher level. The reality is that motorcycle manufacturers can specify this mysterious and old standard to dissuade consumers from turning to $1.20/qt automotive oil when there are $3/qt bottles of oil on dealers shelves that are being marketed as motorcycle-specific. Follow the money. The newer specs (SJ and SL) have a 1000ppm cap on zinc and phosphorus levels in order to facilitate EPA-mandated catalyst longevity requirements. I believe that phosphorus is toxic to all catalytic-convertor technologies currently in general use. 3. The current API SL and ILSAC GF-3 oil specs have given us what are unquestionably the best automotive oils yet. The bar has been raised to unprecedented levels in the areas of oxidation resistance, deposit control, reduction of oil consumption (by reducing volatility), and other good fun stuff. The reduction of EP lubricants tends to be offset by the improved shear-stability inherent to SL oils. You don't really need EP's if the oil film doesn't break down in the first place. 4. A not-very-comprehensive Japanese (JASO) oil specification known as T903 is the only motorcycle-related oil specification in existence. This spec sets guidelines for sulfated ash, evaporative loss, foaming tendency, shear stability, high-temp/high-shear, and performance in three different frictional tests. It DOES NOT deal with amounts and types of EP additives. Also, I don't believe that T903 discusses friction modifiers. It's conceivable that an oil that contains the dreaded "energy-conserving" friction modifiers could still meet all JASO T903 standards and qualify for its "MA" designation, which is a hallmark of motorcycle oils. God forbid! To date, I have found three non-motorcycle oils that claim to meet at least the frictional properties of JASO MA: FormulaShell, Texaco Havoline, and Petro-Canada's DURON oils. 5. Like EP additive levels, the "energy-conserving" requirement for friction modifiers does not apply to the heavier oil weights that we use in our bikes. 6. The term "synthetic" refers to the oil's base stock. Depending on which side of the Mobil vs Castrol lawsuit you were on, a synthetic is made with either groups 3, 4, and 5 base stocks (Castrol), or just groups 4 and 5 (Mobil). An oil's additive package is just as (if not more) important than the base stock, and a synthetic with a poor additive package can UNDERPERFORM a conventional oil with a good additive package, depending on your specific application. The best oil to use is the one that performs well in your specific application, period. This can be determined by oil analysis. 7. I've seen more than just a few spec sheets and analysis reports for popular motorcycle-specific oils that give NO INDICATION that these oils will outperform a mass-market car oil in any respect (other than retailer profitability). They do not have superior viscosity retention (one of the biggest issues facing the oil in our bikes) nor do they have unusually high amounts of EP additives. In fact, some of them even have zinc/phosphorus levels UNDER the aforementioned 1000ppm API SL limits. In a nutshell, oil selection for motorcycles is a topic that's high on rhetoric and low on solid data. The marketers of motorcycle-specific oils have holes in their arguments big enough to drive a Givi-equipped KLR through. I'm still trying to dig up trustworthy data that closes these holes and I'm not getting very far... RM
