Tiny, you are slipping a little. Comparing the price of all formulations to the price of regular gas (forumulation 87 octane) is an apples to oranges comparison, period. Do you have any link that tracks the price of regular gas at pump for last two years? Does the EIA have a chart that just tracks the price of regular? Until you have that you can't say with a straight face that the EIA is better than gasbuddy. Originally Posted by adav8s28Adav8s28, you're obfuscating. And you don't understand the definition of the word formulation as it applies to gasoline. What you're trying to say is that it only makes sense to look at a price series for a particular grade (87 octane) of gasoline, which doesn't make a lot of sense to me. But it doesn't matter. Look at whatever formulation or grade you want. And don't cherry pick dates, like you did with your 18 month graph that started in March, 2021. And you'll find the price of gasoline was up about 50% from the time that Biden took office (January 20, 2021) until when Russia invaded the Ukraine (February 24, 2022). For example, this is for 87 octane grade (regular gasoline) in Texas:

The price went from about 2.08 when Biden took office to 3.20 when Russia invaded Ukraine.
