Removing oil stains from carpets

The other day the oil bottle fell onto the carpet in our dining room while we were asleep and we woke up to see a huge oil stain with half the oil seeped into the carpet. I tried using the resolve carpet cleaner intially and at the end of it, there was oil still present on the carpet after using more than 20 paper towels to blot it up and 5 cleaning cycles.

I decided to go to the internet to seek help and came up with these links:

I also came across a video whose link i cannot find right now that suggested sprinkling flour/corn starch onto the carpet to soak the oil up, leave for at least 6 hours and thereafter vaccuming the same. Well, i spent at least a kg of whole wheat flour. I would sprinkle liberally (around an inch layer) and at the end of 6 hours the flour would be seeped with oil. I thereafter vaccumed it and repeated this procedure thrice. Since there was so much oil, the stain was still visible.

We went to Kroger and bought isopropyl alcohol (95%). According to the links one is supposed to pour onto a wash cloth and then dab to absorb the oil up. My husband just poured the alcohol in before i could say anything ! Well, it looks like it worked and i blotted up the oil with paper towels and today the carpet is free of both the oil and the stain.
