When I did it, it seemed to enhance the speed, while taking the edge off. I took those on days 1-2 on one binge. Almost at the end of day 2 I started taking morphine. By the dusk of day 3 I started having visual distortions. You know how if you get close to a really old TV, how you can see little bitty red, green, and blue, dots that make up the picture? Well, when I would look at people's faces, I saw those types of things, except a little bigger, just coming down their faces in waves. I was extremely fucked up by this point from lack of food, sleep deprivation, and just simple toxicity lol. I didn't take oxycontin per say, but I was snorting 30 mg roxicodones. Everyone is different, but I would use caution as I wasn't able to drive BEFORE I started having the distortions (and I've driven for 4.5 hours straight on lucy before).
