I was wondering is the only requirement for OGL that you have x% of your product as open source? eg do I have to run a d20 like game to have it OGL.
No. The game does not have to be as close to
d20. Also, you do not need to meet any minimum amount because
Open Gaming License does not have any stated minimum nor maximum limitation.
(The "minimum 5% OGC" requirement criteria comes from the other license --
d20 System Trademark License -- if you wish to use the "
d20 System" logo. Do not confuse the two.)

I am asking because the two OGL products that I own are Conan an Mutants and Masterminds and althought these products have character creation and leveling they are still very D20 like as opposed to GURPS.
But they don't advertise as being
d20 (both product does not carry the square "
d20 System" logo/label) nor do the products stated they require
Dungeons & Dragons Player's Handbook or any Wizards of the Coast Core Game Book with Wizards' trademarks.

I am asking if one could make a game like GURPS a OGL game if one wanted or are there still some restrictions.
If you wish to create a new rules system and place them under the OGL, you may do so. Just make sure you fully understand the license.
As someone else have stated, there is another rules system (non-d20) that is under the OGL:
Action! System.
