Here's the thing about oil.
We are all creatures of habit. We like to use whatever we used before.
The dirty little secret is-nobody has ever heard of, or knows of a case, where any engine ever suffered an oil-related failure due to the actual oil used, when something close to the proper specified weight was changed on a maintenance schedule close to what the manufacturer specified.
I'm not talking about a mechanical impediment to lubrication, such as a bad oil pump. That can hurt any engine regardless of what oil was used.
So, you will hear emotional responses to oil questions, and the following phrases:
XX has always worked for me
I've used XX and my engine runs great
My mechanic recommends XX
My bike runs better on XX
All of those phrases could be substituted for any brand of oil. It is no secret that synthetic flows a little better at start up, and therefore starts to lubricate and protect a second earlier, and holds up to heat abuse better. That's an oil type criteria, not a brand-specific function.
Ok, let the arguing begin!!
Use whatever you want, in the weight and change frequency specified.
Modern oil works great.
