Skoot,
yer brilliant. Thanks for the input. Think I'll grab some STP next time I'm out. I'be been thinking about the changes they made to Rotella awhile back in limiting the Zink, and was wondering if there was an inexpensive way to supplement my oil a little. Ima 'suming that you chose that 6 oz amount for a reason? I know there's always a reason behind your rantings.

You must be talking about somebody else Gary. I don't put any additives in my oil during changes. The only time I'll add ZDDP (GM EOS) is if I need to extend my normal 5,000 mile oil change interval due to travel. Personally, I am not a big believer in additives. The major oil companies spend big bucks to figure out correct formulation of oils and I don't believe these smaller 'snake oil' additive companies have outsmarted the original manufacturers. And nor can we. (But I read it on a forum! :blink: ) From what I understand, just about every oil manufacturer discourages oil additives since in could upset their own oil package.
I have been using Rotella 15W-40 conventional for a long time and hundreds of thousands of miles. But price has gone up from $8.50/gallon years ago to $13-$14/gallon currently. At that price, I'll spring for the synthetic Mobil 1 which is similar or even cheaper than the Rotella 5W-40 at Walmart. I don't think the FJR benefits from synthetic oil in any regard but I am after the higher ZDDP concentrations. I too had in the back of my mind that Rotella had reduced ZDDP a while back and read that the Mobil 1 15W-50 was high in ZDDP.
Gary, as I understand it, the Rotella oil continues to have over 1200 ppm ZDDP additives. That's pretty good compared to most other oil. Mobil 1 Racing has 1600, and Mobile V-Twin has about 1400 (going from recall). All of those are acceptable for the FJR. The problem is, the ZDDP package on nearly every car oil is in the 600 to 800 range and falling. It's not a bad idea to supplement it a bit, but based on Blackstone oil analyses I've seen the Rotella T6 looks good out of the bottle. I was a little concerned with technical analysis of the Valvolene 4 Stroke Motorcycle which is a bit lower than I'd like, so I would definitely consider adding a package to that.
Most oil has published technical data or you can get Blackstone reports. All the hearsay in the world is worth exactly what you pay for it..
It had been a while so you made me go do some research again. You are close, but a bit off on some numbers. Below info comes from these two Mobil 1 charts, if you are to believe the manufacturer. Sure would like to see independent testing.
Mobile 1 Zinc Leve Bar Graph and
Mobil 1 Product Guide.
My Mobil 1 15W-50 has 1300 ppm ZDDP. Higher than most but not as good as......
Mobil 1 V-Twin 20W-50 and Mobil 1 Racing 4T 10W-40 has
1800 ppm ZDDP!
Wow! That's almost enough to get me to pay the ridiculous prices for those oils. Except..... I've got hundreds of thousands of miles on the FJR with conventional Rotella oil with no issues, and I can be doing 5,000 mile oil changes every 3-5 weeks. And I am one cheap *******!!!
In general, I believe everybody worries about oil WAY too much and we pay big $$$ for these absolutely superb freaking oils that we really dont' need and that don't give us any advantage whatsoever. And how many of these folks who buy these high dollar boutique oils actually put more than 30,000 or 40,000 miles on their bike before they sell it for something else? WAY before any engine life considerations come into effect. But hey, if it gives somebody a warm fuzzy to throw their money away on oil that is the dog's danglies, well, who am I to give a ****.
As for Rotella, I could not find any specific info about ZDDP levels. All kinds of here-say on the net in the 1000-1200 ppm range. I also couldn't find any distinguishable difference between the Rotella 15W-40 conventional and the 5W-40 synthetic. So who freaking knows? If anybody can find
recent manufacturer claims or better yet independent testing that would be great.
So, the million dollar question is how much ZDDP concentration is desired? Or enough? And after a certain level, is MORE any BETTER?
Sticking with my relatively inexpensive Mobil 1 15W-50 for now.
Now, as for this crap ethanol fuel we have to use.......... You don't want to know about the $$$ I spend putting snake oil additives into every tank!
Who is to deny me my warm fuzzy?!?!?! :lol:
