You're kidding, right?
There's tons of oil change threads/arguments.
For the record, your bike and all other T500 variants hold about 4 quarts. The manual recommends synthetic or semi-synthetic 10W-40 or 15W-50 of at least API SH and JASO MA. The recommended brand is Mobile 1 synthetic available everywhere. You can use an oil filter by Purolator Pure One PL14612 at about 2.5 inches long. Or the Purolator Pure One PL14610 about 3.25 inches long. Both will work just fine, or cross reference this to your preferred brand. This is a common oil filter.
Now the argument: Car oil? Or Motorcycle specific oil? Let the fire-fight begin!
(Note: this is a silly argument because the facts are quite clear. However, just try to convince people of this! Quote "My brother-in-law's uncle's first wife's ex-boyfriend once put car oil in his 1972 Honda CB 350 and it destroyed the clutch." Uh-huh.)
