I got a K&N oil filter from Amazon.com
uhh....so its perfectly OK to use it?..that one kinda went over my head:banghead
Doesn't even need to be " motorcycle specific. " As long as it meets grade, quantity and jaso cerifications. Motor oil, is motor oil. Don't buy into all the hype, marketing and he says.
...unless it's car oil with "performance enhancing" or "economy" additives, THAT can very well destroy the clutch.
So they say, my brother in-law has a 98 Cbr 600. Seen nothing but standard Valvoline automotive oil since day one and has 55k. Original clutch, never the slightest issue. That's not the only time I've seen it either. People can believe what they wish. But, I believe as long as the clutch is receiving the proper amount of oil. As far as the additives. That's why I mentioned Jaso.
Standard Valvoline doesn't have those additives either :idea A car oil can be JASO certified and still have such additives. They are there to make the oil more slippery, to decrease friction between engine parts. That's not an issue in a car engine since the engine oil doesn't get to the clutch in that, might actually be beneficial.
All you say, is true. It does not state in 1 single motorcycle manual that I have ever seen. To only use motorcycle specific motor oil. The manuals only state to use suggested additives and to stay away from others. People use Shell Rotella diesel oil with much success for long periods of miles. I don't use car oil in my bikes. I am simply stating that automotive oil is fine to use as long as those ingredients are present or not and using only motorcycle specific oil is a load of crap.Standard Valvoline doesn't have those additives either :idea A car oil can be JASO certified and still have such additives. They are there to make the oil more slippery, to decrease friction between engine parts. That's not an issue in a car engine since the engine oil doesn't get to the clutch in that, might actually be beneficial.
But in most motorcycle engines (and certainly all current Japanese bikes), the clutch is lubed by the same system as the engine and gearbox - if you then add additives like PTFE (Teflon) to the mix you may very well get clutch slip and the clutch will stay slippery even after an oil change. That has nothing to do with belief, that is simple fact and even common sense.
But again, standard Valvoline doesn't have it - so READ on the bottle before pouring just anything into your engine
Dude, we're saying the same thing :lmao
If my memory serves me correct. Motorcycle specific oil has only been around for 10 to 15 years. Just something to think about. That may be stretching it. It may be less.
Yes, JASO MA/2! No mention has been of the suffix yet, only JASO :idea
Energy conserving oil(s) were introduced ~10y.ago. or so. The amount of friction modifiers being used in such oil affects the clutch and makes it slip under high load. Existed API classification/existed standards didn't address that issue so japanese had to introduce new standard (JASO T904-MA/MB). It takes care about those additives (friction modifiers mostly) and divides oils in safe for wet clutch/not safe.
Um... No... :dunno
