Would you use synthetic or regular oil at the first service interval?

Thanks,

After 1000 miles....

Opinions vary. Corvette, Porche and others use it from new.

The whole "It's more slippery" myth has been debunked.

I changed oil with regular at 500 miles, again at 1500-2000 miles, then synthetic at 5000 miles.

Me? Synthetic. Either one is fine though.

I have felt the difference every bike I have changed to synthetic. I have changed to synthetic at the first 1000 service on every HD I have had with no problems.

Synthetic

I think the main reason is that synthetic oil has higher viscosity values under high to extreme heat than dino-oil. And being air cooled, with factory lean AFR, it should be a no brainer. I know that it is almost twice the cost in most cases, but small price to pay for good engine health IMO.

I would for sure switch to Syn after the 1000 mile service.

DevilDogBagger, I was talking to a guy who pulled into Corbin's (Hollister, CA) who does the Iron Butt runs across Death Valley, he convinced me on AMSoil, then I went to Trick Gas in Rancho Cordova to purchase it in the gallon jug and this guy is telling me he uses it and changes his oil once a year if it needs it or not! So I'm not that gun ho about much better it is, but they have test and documentation. I change it as Harley recommends. You will feel the difference, I use the shockproof in my tranny and AMSoil in my motor.

After my first oil change I always go with Synthetic in everything.
