Vedin kyllä synteettisellä nythahaa...

sanoi:But before you go rushing to buy these products, it should be noted that these are racing oils, and, despite manufacturer claims of viscosity retention performance identical to standard viscosity oils, are made to be changed on a much more frequent basis. You should take a close look at the Tapered Roller Shear Test that demonstrates an oil's ability to maintain viscosity over time.
Looking at the motorcycle-specific oils, it's notable that the Motul 5W-40 version does not hold up nearly as well as the 10W-40 version (in fact, slightly worse than the auto oil). Motul and Maxima both claim that their ultra-lightweight-viscosity oils would last as long as normal 10W oils. Because we only tested the Motul version, we cannot say for sure that the Maxima Maxum Ultra would suffer the same loss. Yet our dyno test shows that both these oils post a horsepower gain. We consider ultra-lightweight racing oils such as 0W and 5W a special category of race products that should be changed on a strict regimen. Before you decide to run them, you need to weigh the risk of viscosity loss versus horsepower gains and make your own decision. Until more data convinces us otherwise, we would stick to something more practical for the street.
Kääntäen sama asia: tuo 1,3% teho-ero voi olla vaikea kuroa kiinni muin keinoin viritetyissä racing koneissa. Tehoja on usein vaikea lisätä tiettyä määrää enempää, ja koneet ovat kohtuullisen tasatehoisia, joten miksi hukata arvokkaita heposvoimia Delvacin tms käyttöön.nonnih, nythän se on todistettu ettei ne racing-öljyt tehoja tuo, tuommonen ~2hp eroa 150hp pyörässä voi tulla jo kuun asennosta....
