So I went tanning in my backyard yesterday and I got a tiny bit dark but not much... I didn't put anything on or anything like suntan lotion or anything.. but I just found banana boat spray... it sayd dark tanning oil... moisturizes and nourishes for a long lasting tan lol this is going to sounds really stupid since it says on the bottle... but will it make me tan lol... if I put it on the go outside... or is it like sun block?

If is a sun block then it would say it is.
You have to use it every time you tan through the summer. It doesn't make you instantly tan within one or two uses.
You can use it when on the go outside but if you are going to be in non sunny places more than the sun it isn't going to do much good.

Usually tanning oil has little to no spf, which isn't good for your skin.

I don't know if this is bad, but I like to put on my regular spf, and then I put on the tanning oil. Tanning is slower that way, but it works!

I'm half swedish, so I'm naturally fair skinned, but I've been vacationing on the southern italian beaches for at least a month every year for the last 6 years. I've learned a lot about tanning. If you use after-sun moisturizers when you're done tanning, your skin recovers better and it's less likely to peel. Real aloe is really good for any pinkness, but try not to get pink.
