Not too mention one of the "experts" (jestal), who seems to have been very knowledgeable, has replaced most of his informative posts with the word "gone". Yeah that is incredibly useful. :rolleyes:
That's what happens sometimes when feelings get hurt. If you take the view that forum posts are either informative, amusing, or irrelevant and worth every penny you paid for them, it's way more fun IMO. ;)

BTW, Mobil 15W-50 Synth works well in my 05 FJR.

Getting back to synthetic oil (if anyone really cares), I use it and probably change my oil less frequently than some people tell me I should. Normally, I will go 5-6 thousand miles but if I am on a major trip somewhere, I don't sweat it if I am a little beyond that. Conditions have a great deal to do with the effective lifetime of any oil. A bike that gets ridden a lot; longer trips at moderate temperatures and normal highway speeds is far less hard on oil than one that gets used for a lot of short hops or under conditions with high ambient temperatures and dust. I may change my tune if I run into compression issues later on but at 60,000 miles, everything is good so far.

slick 50. love it. even added water to the crankcase just like the salesman did.

actually Amsoil... it makes me feel good (i've read all the white papers) and i really don't mind the cost because it makes me feel good.

 
I've been running full synth oil in all my vehicles since the early 90's. Multiple bikes, multiple brands, multiple models, all with wet clutches. Never a problem.

There have been times when a milestone service resulted in the shop swapping oil and me forgetting to tell them not to (or to remind them synth). Each time I knew before I got out of parking lot simply by the way the shifting felt. I can also tell when I try to extend a service interval long that I should have (by the shifting getting "more robust").

Mobile 1 15w50 and, since my scoring a pallet of their full synth moto-specific oil, that MTX stuff (or whatever they call it).

I swapped my 83 GL1100 to full synth when I bought it. It has 72,000 miles on it at the time (early 90's). It wored fine.

Synthetic oil? I've never heard of it... that must be new!!

:p sorry couldn't help that ...

I've heard that if you have a higher mileage vehicle, not to change to synthetic as it may cause those seals to leak. Something to think about.

First time I used synthetic in one of my bikes? hmmmm, more than 10 years ago...

This is my favorite part of this thread. :p

Sadly even the links they provide are all referencing discussions from 6-7 years ago. So NOTHING has changed in the Synthetic oil world in that time? Not too mention one of the "experts" (jestal), who seems to have been very knowledgeable, has replaced most of his informative posts with the word "gone". Yeah that is incredibly useful. :rolleyes:
Exactly, nothing has changed in the synthetic oil world in a lot longer than 6-7 years. Jestal's info, while quite informative for it's day, predates 6-7 years by another 20 or so. That man could tell you exactly how to adjust the valves on a '62 Valiant, but didn't have a clue about EFI or most any modern system. Every single post of his rambled off into the distant past. Though often containing some good pearls of wisdom, in with the piles of poo.

The thought wanders, how long did it take him to search and delete every one of his posts? He could have been out riding! :lol:

Oil, clean and slippery is good. Oil hardly ever "breaks down" in normal use. That's the myth, that oil somehow wears out. It just gets contaminated by combustion by-products and other particles. Some of which are caught by the filter, the smaller ones are not, thus the change in color. If you tested your oil, you'd find out that it's perfectly good for a lot longer than you thought. But every ad you see hammers in the "3 months or 3k miles" song, which generates huge income for the associated businesses.

Glad you're going with what makes you happy. :thumbsup:

You are dead wrong on this one. Jestal knew his ****. His knowledge of oil came from development of GM's oil life monitor. And before he retired, he was involved with the development of what is now the CTS-V. The current one. The one with the Corvette ZR-1 engine.

Sorry my friend, while I take nobody's advice as gospel, I learned more from that guy than I have from anyone else. Ever.

Fair enough Skooter. I never did catch what was the straw that broke his back and made him leave? He was a wordy sumbitch.

Well, let's see...

I would like to say that he was "precise" with his explanations. I was grateful for the knowledge that he imparted. Wish he was still here.

I would LOVE to own a CTS V .. but any ways, I am the 3rd owner of this bike and the first owner was nice to make notes and he used Moble 1 Syn 10/40 .. So i am sticking with Moble 1. Now after some shopping i find that auto part stores sell this stuff for about $16 a bottle, "BUT" Wally World (if you can find it) sells it for $10 a bottle. Thats my 2 cents .. Cheers All

Been using the Mobil 1 20/50 for V Twins. Tried the Rotella synthetic but the shifts seem to feel better with the 20/50 (could be my immagination). Also using Mobil 1 filters.YMMV. :huh:

 
I run Amsoil 10w 40 synthetic and Amsoil synthetic gear oil. Whether synthetic is the be all end all, well I don't know. One thing I do know is I can't afford two motorcycles, so I need to keep this one running. I hope Amsoil is what it says it is, and lives up to the claims. To each their own.

 
We've run this controversy to death in my other forums; car & powersport, and it's a good one.

Bottom line

Synthetic has slightly different lubrication properties (molecular speaking) than natural oil/petroleum based products. They both adhere and space themselves between friction a tad different. So end result by most real technical lubies (which I don't claim to be!)... use a Synth blend, you get the best of both worlds.

 
Changed my oil last week and made my own blend. I had left over Mobile-1, some Dino Rotella, and Syn Rotella from previous changes. Oil changed, and the cabinet is much neater!
