For most people, that seems a little extreme. What kind of oil did you end up using? If you’re lubricating with thin lube, it might be possible that it stops playing as responsively as you would like it to as soon as that extra lube works it’s way out of your bearing during play, since putting too much thin lube will make any bearing play responsively for a while. With a sufficiently thick lube your bearing should stay responsive for weeks, if not months.
If you’re using a lube that isn’t yoyo-specific, it can be hard to tell how thick it is compared to a product that was designed for yoyos. A thick lube should have noticeable thickness to it, not quite as thick as corn syrup or warm honey and flow relatively slowly, while a thin lube about the same consistency as water, but with incredible wicking ability (the neck of my bottle of thin lube always seems to have lube on it, even though i’m very careful to keep it all in the bottle). So, if you put a big dab of lube on a table and stick a paper clip in it, it a nice little glob stick to it, you’ve got yourself a thicker lube. If only a tiny little bead sticks to it, it’s a thinner lube. That being said, you’ve got to use a thick lube for your unresponsive yoyo to stay reliably unresponsive.
