what? i call bs on this one. there is nothing about synthetic oil that would even cause paper to break down. it isn't like it's more acidic or anything.
I agree with you on this one!
Ran an Evo for 95k with a wal-mart, fram or AC filter.
2nd Evo S&S 113 has 65k....Both bikes on Syn oils.
Interesting discussions and good information sharing. I have used Amsoil exclusively in my bike ('99 FXDWG) and all of my vehicles for several years. Different weights and amounts depending on the vehicle of course. Have never seen or experienced an issue of any type...When I've changed the oil (always do it myself) in my vehicles and bike, the oil is only slightly discolored and viscosity seems unchanged from that of new oil.
I live in Daytona Beach Fl and ride in high heat conditions all summer long with Amsoil and have never experienced any kind of oil breakdown or unusual noise at all,I seriously doubt that 90 degree heat caused synthetic oil to break down
60K miles with Syn3. HD wrench recently said "don't run that **** if you want your motor to last". So Last oil change I went with Amsoil 20/50 and never heard so much top end noise. Just over 1k miles since change but it's got to go. What a waste of $. I guess its back to Syn 3.
I'm not gonna brag up Amsoil for selling purposes. I use it in my SG, 4wheeler, pickup and even my Peterbilt. No problems. The one thing I noticed in ALL the posts is that people don't do regular sampling. IMO its the only way to see how your engine is wearing. I recommend doing regular sampling no matter which oil you are using. You can stop major damage or failure.
Amsoil does say you can extend the change intervals using their filters but in some cases there are some vehicles that are prone to fuel dilution and therefore they recommend regular change intervals on those vehicles. But with regular sampling you would catch something like this anyway. Ride Safe
PS.....I sell Amsoil for cost if anyone is interested.
Just got back last Sunday from a 21 day, 7,500 mi trip out to the west coast and back. Thought I would share my experience with an oil issue I had.
Leaving Oh and heading to Sturgis is about 1,400 mi for us. I left on 7/5 and it was in the mid to high 90's all the way out. At about half way through S.D. I started hearing more engine noises, especially lifter noise. After we got to Sturgis and checked into the motel we wanted to head up to Deadwood. Went out to start the bike and the motor made so much noise I thought the motor was going to self destruct. Lifter noise was really bad with a very loud top end rattle or primary noise when when I revved it up.
Decided to head for Black hills HD to have it checked out. The head mechanic came out to hear the motor and he said, " that's the most noise he ever heard a motor make". Well, I had to have the motor taken apart to see what had happened. When he drained the motor oil, the oil was as thin as water and was black as tar. This after 1,400 mi. In order to make sure no damage was done to the motor, the motor was disassembled, removing the top end, cams and primary cover (as it sounded like it was rattling in the primary).
After taking a mic and checking everything, no damage was found and everything was normal. I felt I had to at least do this much tear down to make sure I had a motor that would finish the 7,500 mi trip.
Conclusion: The Amsoil probably lost it's vicosity in the high 90 degree heat and had literally burned up, even though I maintained oil pressure (thankfully). The engine noise's I had were from the viscosity not taking up the engine tolerances built into all motors. The motor was put back together and HD syn was put in. I completed my trip, across the desert twice and riding in temps over 110 degrees, with no more problems. Was it bad oil? You make the call, I am only giving the facts as it happened. I have since replaced all three holes with Redline and will now see how this oil runs. Sorry for the long story.
I rode up to the Sturgis rally from Chicago this summer ....used Amsoil for the Tranny SVO 75w-140 and AHR SAE 60 for the Engine....She purred like a baby kitten...real nice quiet and smooth......no problems at all....
don't kow if I did it right or wrong but I was pleased with the performance.....on to the winter modifications.....
[QUOTE=SFTL 1;7073731]While Bradd Penn V2 may be an excellent mineral based oil, it is still a mineral based oil. In the summer while riding in 90+ degree temps & high humidity, if I get stuck in a traffic jam, it's not uncommon to see my oil temp hitting 250 degrees. I don't know about you, but personally I would not want anything other than the best "all" synthetic oil in my engine at those temps...
If you dig deep enough, as synthetic oil makers like to hide this info,true synthetics many times cause more wear in an engine.Here's why-if you have ever poured synthetic oil in a funnel as you near the end of the bottle where the oil is trickling out,you may notice it kind of beads up and runs right off the funnel,it doesn't flow or stick on an object the way regular oil does.It does the same on the metal inside your engine,it doesn't cling to the metal like dino oil does,so at startup you dont have much lubricating the engine until the oil is pumped up,actually causing more wear at startup.That's why engines running synthetic generally sound like crap at startup.This problem is even exaggerated on a motorcycle that goes for longer periods of time between startups.If you think I am just giving an opinion you are wrong,I spent much time studying oil as I raced cars with high revving expensive engines,so I spent much time studying engine oils.
I didn't see any "dry" parts in mine after tearing into it. To the noise post: a little reading will show you that syn is naturally noisier than dino.
That said, it's winter and I went back to dino, Valvoline 20/50 specifically. Great stuff, and as long as she stays below 235, it stays.
60K miles with Syn3. HD wrench recently said "don't run that **** if you want your motor to last". So Last oil change I went with Amsoil 20/50 and never heard so much top end noise. Just over 1k miles since change but it's got to go. What a waste of $. I guess its back to Syn 3.
Changed over from dino to Amsoil @2K and at first the amsoil was quiet but towards the end of the duration of the oil change it sounded like a sewing machine.
Switched over to Mobil 1 and it still sounded like a sewing machine.
Now run regular BP, not the V-twin specific, as it's not necessary. Motor is much quieter too.
Next time though will run straight BP 50 weight,as opposed to 20/50 as I don't run in temps colder than 30 degrees.
Sorry if this has turned into an oil thread..on my end anyway.
