Not the best at math. Therefore I only use Castrol 20-50wt automobile oil all four seasons of the year. 56,000 plus miles on my 650 and not one repair ever to the engine. Not one! In fact my header pipe is as shiny chrome today as it was the day I bought it new off the show room floor. No oil leaks and runs like a clock. I don't need no Rotella or ZDDP! I did change the cam chain at 30,000 because I thought it was required. After it was apart I realized it is still in great shape and might reuse it again someday. I don't ride hard but I do ride pretty fast. I just checked the tensioner and it is still within limits. I probably will do the Versy this winter tho just to be safe. Am I the only one here that uses auto oil and 20-50?

Dave, you will need to replace the table in the tech section.
If your research confirms that PPM numbers over 1400 are more and more counterproductive, then you should truncate the table as Boule's old 1800 PPM top end is a very old racing oil spec.
I think Redline goes up that high in their tables, but they are dealing with drag racers and stuff like that.

Rotella is auto oil
and diesel oil
and moto oil
and genny oil
on the Honda Rebel forum a lot of folks use Castrol from 10-40 to 20-50 (castrol above 10-30 is not 'energy conserving') and are happy as larks with it
one fella has over 100k on his rebel with Castrol
We choose Rotella for the ZDDP, which experience of some members suggests out engines need
This brings up a question someone else has mentioned before: What if the damaged engines weren't because of a lack of ZDDP? what if the real culprit was something else? (low idle speed comes immediately to mind)
what if Castrol has something in it that does the same thing?
Hmmmmm

Art:
The failure caused by low idle speed, and lack of ZDDP appear to cause 2 seperate modes of failure.
The low idle speed kills the cam bearings and doesn't seem to do much damage to the cam or rockers. I guess the low speed doesn't overstress the cam lobes or rockers.
The lack of ZDDP doesn't do anything to the cam bearings and they stay smooth and shiny - but it causes the cam lobes and rocker to wear too fast.
If someone had a low idle speed and oil without enough ZDDP - I suppose they could damage the bearings and wear out the cam lobes and rocker simultaneously.

I dunno....most folks formulate 20W-50 with high doses of ZDDP as it is not an oil approved or listed for use in modern fuel injected engines.....you won't ever see the "Energy Saving Star" on a bottle of 20W-50. Most stuff that uses 20W-50 is vintage or race oriented. Somebody needs to find out if the Castrol 20W-50 has friction modifiers and how much ZDDP is in it.

Checked at Advance Auto Parts, they didn't have any redline stuff, they did have this from Lucas, is that the same stuff, or at least OK?

NO Lucas.
Not approved for wet clutch use at all by the mgf. Contains TONS of friction modifiers and the Lucas base oil contains bad polymers as well.
We've checked Lucas before and found only bad news, and we have also had newbies come on board after using the stuff and contaminating their clutches VERY BADLY.

The only good supplements we have found require internet ordering. Try Amazon, they have the approved stuff.

If someone want to say Castrol oil is good stuff, please refine your statement down to WHICH CASTROL product you are talking about.
Castrol is like Kendal now-a-days, just a brand name that is currently owned by British Petroleum (BP) who trots it out occasionally to try to sell something to the American big engine muscle car owners.
Castrol oil built by Castrol Inc. back in the day was a high ZDDP oil, like many others of the era. It was refined from Pennsylvanian crude and it was a good oil back then.
This is NOT what you are getting today -- it is a BP standard formulated oil in a Castrol jug.
Castrol Edge seems to have somewhat better specs that most of the Castrols lately, but it isn't consistent year to year and it gets weaker every time the general car specs change.
Pick which one you want to contest, and let's be about it -- been a year at least since we did a Castrol lookie-see.

Thanks Oldfeller. But just to make sure I am ordering the right stuff, this is it, right?

NO, what? You use 20-50?

Is the new chart settled?
Also, what date/lot# did the ZDDP level drop from 1200 to 1100?
