What do gas rc cars run on?

i am looking for a gas rc truck. i dont want a fuel that is hard to get a hold of preferable i want a truck that is powerful and runs on straight gas. none of this nitro stuff. do they have this or what would be a good choice for convenience when it comes to fuel?

They do make a larger scale vehicle with a similar size motor as a gas weed-eater. 23cc I believe. Usually about $1000 for a RTR though.
