You want this without question. Has great Gulf section and very very good Sinclair and Texaco.

Then for sure Tom Allens book mentioned above. Which is also great!! But has no Gulf nor Sinclair. But great Texaco section.

Ultimately you need both of these and also Oil cans for Collectors. Which is also very good!!
They are great reference material for many other parts of the hobby. Not just oil cans.

Welcome to Oldgas!
