It's a good idea to change the oil after using it, is what he said.

 

Never hurts. Might as well just do it before you do an oil change.

if through a vac line then no u dont have to only if u use it as a oil treatment then yes!

however changing your oil is never a bad thing so I would say if it is due then do it if not dont worry about it and do it when it is due

 

I use Seafoam instead of water when I do the vacuum sucking job. Here's what I do. On Thursday I add a can of Marvel Mystery Oil to the crankcase. (I suck a pint or so of oil out first) . Then on Saturday, I run a can of Seafoam through a vacuum line. After that's done, I change oil and filter. Drain the oil. Crank the engine and let it run for 10 secs or so to clear out the filter and the oil cooler. Replace with new oil and filter and away I go.
