buy MC specific oil and you are good. The zinc is there to protect the trans primarily,

Don't you just love oil threads.

No, just the opposite.  Apparently, back in the day, oil had zinc in it, but no longer. Some choose to add zinc....

Adding zinc is fine to newer oils, the level is lower now because of catalytic converters even Rotella, but too much is harmful also. Have to do a little math when you know your formula.

I just went to Autozone to buy some oil. I asked for Castrol 20W-50 Motorcycle Oil. Their website said they had some. The clerk got me 4 quarts and I bot it and left. Later I looked and the bottle did not say Motorcycle Oil, so I took it back. Two clerks looked for MC oil on the shelf and it wasn't there. A youngster (seemed to have authority) said "I know we've got some" and had to go in the "back room", to get the real stuff. We had a nice conversation about my project. He said he learned how to ride on a K6. His bro put a dirt bike tire on it and they all rode it around in the field. Then parked it for 16 years, now his bro is restoring it.

Anyway, ask for and use MC oil.

It would be wonderful with ONE sticky oil thread were all fantastic information about the oil our CB's need or not can be gathered.
It must be a huge container with NOS motor oil from the 70-80's somewhere....

Ekpent, I am changing to the Valvolline 4 stroke dino 20w-50 motorcycle oil that Hondaman says has a higher zinc content than normal. I have been using ZDDPLUS for a few years. 4oz/ 4 qt. oil. Is this now too much zinc? Dan

about oil... I got a delivery from Germany (levoil.de) this afternoon delivered direct inside my door.. 24L synthetic oil :) Aral Super Tronic 0W-40 to my car with small 1.8L engine, only 4L oil each change.
Similar oil cost 4 times more here at local shops.

Typically, if it says Energy Conserving or the new Resource Conserving on the API label, it is harmful to wet clutches.
The Shell Rotella T-6 synthetic diesel oil is even rated for use in motorcycles with wet clutches (Note the JASO ratings)...

Shell is an Anglo-Dutch company and it's funny to read that in the US Rotella is sold so cheap in warehouses. I believe in Holland Rotella goes under the name of Rimula and it's bloody, bloody expensive where Valvoline or Halvoline is the cheap brand sold in all kinds of warehouses. What I would like to know, is if Shell in the US also markets a line of socalled "Motorcycle oils" as Shell does in Europe.
My point is this: if a company like Castrol has a line of socalled "Motorcycle oils" I can understand that Castrol will not name the JASO spec on their other oils even if these oils meet the JASO requirements easily. If you market some oils as specific ("Motorcycle") you can ask more money. Shell puts this JASO on their diesel jerrycans and some of you seem impressed by this. Now, you may call me suspicious but... somehow I have the feeling Shell has NO specific "Motorcycle oils" on the US market and so, by putting JASO on their Rotella, can catch consumers that would otherwise go for a specific "Motorcycle oil" offered by their competitioners.

And I thought that German prices were outlandish. When I get my cars serviced here in Germany, I always bring my own oil, which I buy in the PX. That is pretty much what all the Americans stationed in Germany do. I take it then that oil in Sweden isn't transported in tank trucks  but in armored vehicles, heavily guarded.

How about:
    Follow the recommendations in your owner's manual.
    Use motorcycle-rated oil.
    Use synthetic if you want to.
    Add (a little) zinc if you want to, but be sure not to add too much.

It's so funny every time the popcorn jokers take the effort to present their "jokes" over and over again. Why? What are they doing here in this thread?  To use Synthetic oil or not to use Synthetic Oil is the question? - one would thnk that clearly warns them there's nothing in it for them. Or... is it?  ;D

You've never read anything in these threads that you didn't know? I find that hard to believe.
Another thing. Does any of you have experience with these tissues where you can put some oil on to check if the oil is still good? It's used a lot in the professional transport world but that's all diesel ofcourse.

Same electrical problem however, can be asked and answered over and over and over again....

An oil thread is really needed, the solution is a sticky one at top with fresh information and new can be asked in this only thread about motor oil for our old CB's.
