Regular Oil

[REDGKO]

Ok wanted to through this out there to see what you guys think.

Took my bike to get the 600 mile service today. When it was done, the guy said they put regular oil in it to help with break in period.

When I called and ask about the service yesterday to make the appointment, I was told they use synthetic, so I didn't specifically ask today that I wanted synthetic, figured that was what they use because that is was they told me yesterday.--but that is the side point.

Main questions is, Is that going to hurt my bike? I know people said that in the past about putting regular in at first helps, but with these newer engines, I never heard that. From reading other posts, people use full synthetic all the time.

Kinda irritated they put regular oil with out talking to me first, but more concerned is how it will impact my bike.

Wondering your thoughts.

Thanks

I wouldn't lose any sleep over it. If you're really worried about it, have them change it to Synthetic, since that's what they told you they would use.

Redgko, when I brought my bike in for the 600 mile service, I requested synth. Then I had a long chat with one of the mechanics who explained to me that for the first few thousand miles, I should use dino so that everything seats in properly. Later on, I heard from other riders (most likely this forum), that that may have been the case in the past, but nowadays, it's not a prob at all to use synth right out of the gate. In retrospect, I would have put synth in from the get go. There are varying opinions on this, but I agree with Justin; don't lose sleep over it.

I filled with full-synth at the 600 mile service. If the dealer does it, always make sure they don't overfill.

I ran across the OEM's recommendation in the owner's manual for my recently acquired '19 SX+. Dino, semidino, and full synth..all 10W40 were all listed. NBD, IMO.

Yeah I might run it for a week then have it changed. I called the dealer back and they said they would change the oil if I paid for the oil but won't charge me for the labor.

So, they said they were going to use synthetic when you scheduled the appt, then used dino? And now they want to charge you full price for the new oil to fix their mistake? How nice of them.

Yeah, it is quite a debate. Check these out:

"Synthetic oil during engine break-in? Here's what the oil manufacturers say...

One of the myths surrounding synthetic oils is that new engines require a break-in period with conventional oil. The fact is, current engine manufacturing technology does not require this break-in period. As indicated by the decisions of the engineers who design the high-performance cars listed above, Mobil 1 can be used starting the day you drive the car off the showroom floor.

Busting the Engine Break-in Myth

These folks took two identical new bikes and synth one and regular oil the other:
"The truth is, there was no significant difference between the two engines. There was hardly even a discernible difference. The compression and leakdown numbers were stellar and identical on both motors, and all the measurements of the internal parts, including the piston diameter, cylinder diameter, piston-ring end gap, and valve clearances, were all within spec and inline with each other."

"Why things are the way they are: Motorcycle oil

At this juncture, there are two main drawbacks to using synthetic oil. The first is that because the molecules of synth oil are smaller, they are more easily able to pass through cracks, seals, and gaskets. What that may mean is that a leak may form that wasn’t occurring with conventional oil. The synthetic oil doesn’t cause the leak, it simply finds an existing path to exit that may not have been previously identified as a leak. It doesn't cause leaks, rather, it finds them."

(there are other thoughts in the article, as well)
