Olive Oil will not turn white. It will become foamy & thin. I pulled with toasted pumpkin oil, it became thick then became thin & foamy. However, it remained dark & I saw results.
If you want to swtich to a new oil to try something, new ... Great. Don't worry about the olive oil not becoming white. I pulled with it for 20 minutes. When I was done it was neon yellow-green and I still saw results.
I love pulling with coconut oil. Seasame is next on the list.
