2016 48. I just changed the oil in my bike when I realized I bought non synthetic I buy thru Amazon, I bought the “Lucas 20w 50” high performance motor oil not realizing it wasn’t the synthetic Lucas 20 50 I normally buy till I changed it. My question is, is this non synthetic Gona damage my motor ? In a short term use till I get the synthetic? Appreciate any help.

 

Of course it's not going to harm your engine. Just change back to synthetic the next Oil Change

 

No problem. As stated above.

Really?

 

Thanks for the info feel better about it now

 

My opinion but I wouldn't put Lucas in my lawn mower. In every oil test I have ever seen it finishes dead last. But then again its your motorcycle.

 

Your bike came from the factory with HD 360 20w-50 conventional motor oil.

From the 2016 Sportster owner's manual:
https://serviceinfo.harley-davidson....369633!!3!5729


"This motorcycle was originally equipped with GENUINE HARLEY-DAVIDSON H-D 360 MOTORCYCLE OIL 20W50. H-D 360 is the preferred oil under normal operating conditions.
If H-D 360 is not available, add oil certified for diesel engines. Acceptable designations include: CH-4, CI-4 and CJ-4."

The Lucas oil you bought is rated

• Meets or exceeds: API SG / SF / CC / CD, JASO MA & JASO MA-2, ACEA A3

Since the Lucas High Performance Motorcycle oil is not diesel rated CH-4, CI-4 or CJ-4 it technically does not meet the HD recommendations.
The Lucas 20w-50 synthetic also is not API diesel rated. It is API SL rated.

Neither will likely harm your engine.

 

Agree.
