There is a bicycle path that runs the entire length of the section of the stream between Drake Well and Petroleum Center (the upper terminus of the downstream regs area). So, you can hike or bike in either direction as far as you want to drop in and fish. So far as I recall, fall-out-of-your-car access to this portion of Oil Creek is limited to: 1) Drake Well 2) A bridge at a place called Miller Farm which is a few miles downstream from the well and 3) Petroleum Center. There may be another minor road access point (involving a short hike) between Miller Farm and Petroleum Center, I forget.
Personally, when I was fishing Oil Creek, which I didn't do all that much for trout, but logged hundreds of hours fishing it for smallmouth, I preferred to avoid the special reg sections. I never cared for either the number of guys you'll often see on the weekends on the regs sections or the weird out effect that DH regs have on the fish. Fortunately, it is an easy hike on the bike trail to less pressured water under general regs that still has as many fish as anybody could reasonably want. I preferred to fish either at Miller Farm or hike upstream from Petroleum Center.
The entire point is that access to the entire section is easy and relatively quick on foot or by bike.
Oh, better have somebody else independently verify that the stream is still accessible by car at Miller Farm. its been a long time since I've been there and back then, the road in was a little squirrely.
Have Fun..
