Why was Pepsi free in 1985?

"Pepsi Free" was a caffeine-free version of Pepsi introduced in 1982. This product would have been familiar to Marty in 1985, but unknown to a soda jerk in 1955, hence the joke. In 1987, ...

How did Marty meet Doc in 1955 after Doc has travelled to 1885?

The Doc Brown in 1955 is younger than the Doc Brown in 1885, by 30 years. The Doc Brown in 1955 will still live for another 30 years before traveling back to 1885 and being shot by Buford.

Why did Marty McFly need to look up Doc Brown's address in 1955?

He knows where Doc Brown lives in 1985. There's no guarantee that he lived in the same house 30 years ago. Indeed, it seems that he didn't, because once Marty finds his address, he has to (try and) ...

Did Doc Brown warn Marty to never travel to 2020 or what year did he warn about?

No, there is no such dialog similar to that. The meme is not based on any specific Back to the Future reference outside of the fact that it's a movie about time travel. Doc does give Marty several ...

Why didn't Doc and Marty buy "petrol" in 1885?

Part of the issue was that they had a time limit. Doc (and then Marty) was going to be murdered in a week. They didn't have time to do much more than try what they had available to them locally.
