Amsoil.

It was part of a discussion regarding Syn3 oil on the CVOHarley site.

"It was brought up regarding that Syn3 isn't really that bad of a product but actually how pretty good a product it is."

Look what oil came in 1st. That should answer your question.

depends on the lab -- who comes in first --

I won't knock any good oil -- I have my preference -- which changed after30 plus years of using one brand

I won't run Syn 3 because it feels gritty to begin with.

The dealer where I have had them do some warranty work for me asked me what oil I used in my bike When I told them Amsoil they said that was good stuff and they also recommended RedLine oils. They told me the HD Syn3 loses to much viscosity when it gets hot and does not lubricate as well as the two oils mentioned.

Ok, so this reply has absolutely nothing to do with HD or its oils.

However, it does shed light on how important it is to use the oil spec'd for the application.

Awhile back, i had a 1973 454 Chevy big block rebuilt. At that time, the world was on fire for Mobile 1 synthetic. Doing some due diligence, I learned that the Mobile 1 Synthetic had been used exclusively in corvette motors since the late 80's I think. I figured, if its good for that chevy, it'll be good for mine.

Well, about 3,000 miles into this motors life, the cam shed most of its lobes and begun the tell tail back fire and exhaust pop associated with valves not hitting their pre machined targets.

I mic'd the cam and most of the lobs were round.

Talking to the machinist, his first question was what oil did I use to break the motor in. i said mobile 1 synthetic. Of course, he immediately blamed the failure on the synthetic...not necessarily the mobile 1. He explained to me why this was a problem and all I could hear was blah, blah, blah...not my fault.

so I began doing some research on the differences between the synthetic and organic oils.

Well, come to find out...synthetics are so good at keeping the interior metal pieces of your motor from coming in contact with each other that the motor never actually "breaks in".

Now, thats not a problem with the newer LS1, LS3 engines that chevy puts in their Corvettes because these motors are machined to a tolerance that requires very little break in.

However, old school motors built by old school machine shops are very much in need of a break in period and using synthetic prevents the pieces from machining themselves into a proper fit.

so after 3000 miles the motor was still trying to break in and the engine temps got so high on a regular basis that the hardening on the machined surfaces broke down, thus allowing the metal to begin to shed and break down.

so it is not unreasonable that the HD MOCO wants you to use their spec'd oil on their air cooled, possibly still old school machined motor.

Just my two cents. Flame on!

The "too slippery to break in" has been thoroughly refuted, which is why all CVO's come from the factory with synthetic oil.

The dealers in my area sell multiple oils none of which are HD. JR

Yeah, but it's always fun to see. Can "bearing skate" be far behind?

These engines are built by equipment that hold tolerances within .0001 and maintain .0005 in mass production. The only thing that is actually mated in is the piston rings to cylinders and they seat within minutes. The statement that synthetic oil is slippery then conventional oil is based on silly uneducated statements. Both oil types keep the metal to metal surfaces separated and cooled under most circumstances. If they did a perfect job, the engine would never wear out.
Neither is too slick.
