Now in all my other bikes I use nothing but Amsoil motorcycle oil. I had an issue with the starter clutch not catching with the Amsoil, switched back to Castrol and problems went away.
I have seen no wear issues with this oil either after being into the motor at various times doing upgrades and other parts swapping. I have seen wear tests done among various motorcycle oils and GN4 was on the lower end of acceptable for wear range. On the third oil change I switched to Amsoil and immediately found that the transmission shifted smoother and the oil stayed cleaner longer. I no longer use GN4 in anything but this was my personal experience. Very cool, thanks. Another forum had a bunch of praise for Shell Rotella..
Either way, just about everything is cheaper than GN4, and no one seems to give it praise on any other forum.. It seems Honda didn't give as much care to their oil as they do to there bikes, which is a shame.
Amsoil is fairly expensive but from what I have seen and felt how it performs I think it may be the best oil on the market. Last edited: Mar 29, Click to expand You have to really watch the single weight oils now days. Many of them are not made with the best stock and additives that the multis are I was going to say just this. I've used Castrol on most of my bikes over the years. If your like me who keeps your oil changes regular, then really any good grade would suffice.
Greebo Guest. I use Motul 10w40 semi synth' or Silcolene 10w40 semi synth engine oil;. I was also going to try Motul 15w50 semi.. The next time I tried to start that bike, the clutch slipped every time I kicked it over, and the crank wouldn't pass the compression stroke.
Motor oils be they "car" or "motorcycle" specific that have a second number 40 and above Example: 10w, 15w, 20w will almost never be marked energy conserving.
I have never found one that was, but they may exist. As far as synthetic goes, the same rules apply. Make sure that it is the right weight 10w Pour it in your bike and enjoy synthetic bliss.
Synthetics are better than conventional oils. They have a higher temperature tolerance and develop much less sludge when used longer than the interval service is specified, which, for our bikes, is about miles per oil change.
They shift smoother when cold and have less false neutrals when hot - this is my experience. Results may vary. But you may not even notice the difference in synthetic other than by the weight of your wallet I use it for the peace of mind when I'm in rush our traffic on a degree day - stop and go, stop and go.
If you love your bike and want only the best, buy a synthetic. To save money, buy a "car" synthetic off the shelf. If you wan't to save money, even the cheapest 10w oil will do. There is nothing wrong with SuperTech oil - Used Oil Analysis proves that it is just as good or better than most name brand oils when used in cars.
And it is dirt cheap. I have yet to come accross a better deal than that for a motorcycle specific synthetic oil. You can pretty much bet that Walmart prices are better than anyone else's for motor oil, unless someone's having a sale. Flame on haters As for me, I use car oils. I buy Mobil 1 synthetic 10w "car" oil. It works great in my '75 CB When I'm running low on cash, I buy Shell Rotella 15w I only run this in the summer as it is thicker at startup than 10w, which causes it to take a few milliseconds longer to start lubricating the top end.
Rotella is one of the few "car" oils that is actually recommended by the manufacturer to be used in motorcycles. That's what sold me on it. Shell doesn't even sell a motorcycle specific oil, IIRC. Change the oil, use 3 quarts. Have an extra quart around to top it off before a ride. The choice is yours. I appreciate the feedback I realize it was a remedial question here After work I am doing a lube and filter change. Not the synthetic.. Just about any diesel oil still has ZDDP in it.
Main reason to remove it is catalytic converters, it 'poisons' them so automakers want it removed. Wolfie Live to Ride, an all dat stuff! I have used Castrol for over 40 years in all my bikes.
And I am a Amsoil dealer, and still use Castrol Crazypj, do you notice any issues with clutch slippage using Rotella T Triple? I'm doing an oil change this weekend and think I might switch over.
Is adding ZDDP necessary or more of a precaution? Thanks guys! I've had some clutch slip on motors, but, I think they would slip even with conventional oil. I haven't noticed on the bored out from to ish but I did replace the friction disks and alloys with Barrnett parts. Barnett are pretty 'grabby' and slightly thicker than stock so will have slightly more spring pressure.
I use stock plates and heavy duty springs. In my experience, ALL 70's Honda clutches slip at high rpm. Wolfie said:. Click to expand NOT synthetic I don't use any sort of additional additives. Viscosity to suit your climate. Take enough engines apart that have familiar oil history and you will be a believer.
