I don't find anywhere in my 2018 owner's or service manual a reference to a 10k interval for engine with Syn3.

Besides the breakdown of additive package in the Syn3, there is the continual addition into the oil of combustion byproducts, which can be corrosive. The base oil may be fine after 5k, but by that time it has a lot of "stuff"added to it from the combustion, and needs to be drained and replaced. Even a 5k interval is probably too far. The manual sez change oils sooner if the bike is ridden in certain conditions, such as extreme heat, cold, stop and go, rain, dust, and whatnot. Because most of us ride in extreme conditions, it is a good idea to change more frequently. I base my interval on how I've been using the bike lately. I take the 5k interval to be a "best conditions" interval, not to be exceeded in any case. Add in a couple of extreme conditions, and the interval drops to 3k or even 2500.

I would use standard motor oil to save some money on frequent oil changes, but I ride all year long. In winter this means cold starts. That's the main reason I use synthetic, because it doesn't thicken up in cold as much as standard dino oil does. At the other extreme, it doesn't break down and vaporize as easily in heat. These are hot running engines in summer.

 

Do you really think HD would recommend running SYN3 for 10,000 miles when they sell it for $12.95 per quart?

Anyhow:

 

What dealer, I'm in the area and need to be sure I don't use them! Just need to be sure, shoot me a PM if you'd rather.

 

Hey, an oil thread!!! Awesome!!!!

 

It doesn't matter what dealer, the dealer doesn't get a say in it. If you use an aftermarket tuner, your warranty is voided, period, whether you installed it or the dealer did or you took it to a dyno tuner.

There is nothing any dealer can do about it. The rules changed for 2017+ models.

 

Added that little qualifier in bold, for the sake of accuracy.....I know you know that part but others may not.

 

Sorry guys, I didn't just walked away from mu own thread, I just been VERY busy lately.

I just decided to buy the synthetic oil and filter from the dealer, at least I gave that much satisfaction, and did the entire service myself at home since I have plenty of tools. Anyways, at the rate that I ride my bike, my warranty will be over before my 10,000-mile service.

Thanks again for all of your replies.

 

I agree with you about the voiding of the warranty. That also brings up a question about HOW it gets voided. If the dealer is a "look the other way" dealer, how then does the MoCo get the info to void the warranty? I'm talking about a procedure that alerts the MoCo about the tuner, or exhaust, or air cleaner.

 

 

First of all, they aren't "naysayers". And quit trying to tell newcomers here that it is OK to disregard the warnings written in the owners manual. I hope they are smart enough to not listen to your incorrect advice. You also FAILED to indicate what kind of bike your dealer "supposedly" fixed, and if it was a prior year bike to 2017 model year. You also didn't indicate if it was an aftermarket ESP that may or may not have the same guidelines as the MoCo.
So when you make a statement like you did, how about backing it up with solid information about .who the dealer is, what year and model bike you have, an what kind of warranty you have, Aftermarket ESP or MoCo ESP.
Until you do all that, I'm calling B.S. on everything you said.
