I started the break in procedure as per HPI on my XL. I was only able to do 2 tankfulls due to the rain. I had to send back the engine due to the carb being defective and they ran 1 tank after they fixed it. Here's what I used for the break-in. Traxxas top fuel 20% was used and the temp was under 200. You can also see how much oil is in the fuel.
