What’s the difference between heavy and light crude oils? And why do American refineries need both? | American Fuel & Petrochemical Manufacturers
Nearly 70% of U.S. refining capacity runs most efficiently with heavier crude. That is why 90% of crude oil imports into the United States are heavier than U.S.-produced shale crude.

US REFINERIES CANNOT PROCESS LITE OIL
The thing I keep seeing on you tube is that US refineries must export light shale oil to refine it in other countries. I have discussed this at length with several AI LLMs delving quite deeply into process constraints of various refinery configurations and in general this does not appear to be... More on eng-tips.com

April 7, 2025why doesn't the US refinery capacity adapt to light sweet domestic oil in 2023?
As an industry, we spent a bunch of money in the 80s building hydrocrackers and cokers so that we could turn cheap feedstock into the same products we’d make with more expensive feedstock. Let the foreigners keep buying our light/sweet crude and we’ll take all of the sour/heavy garbage that we’re already set up to refine. No need to spend hundreds of billions of taxpayer dollars to solve a non-existent problem. Some refiners (XOM/Blade, CVX/Pasadena) have made changes to their portfolios to refine more domestic crude. It costs a lot of money. That money could be better spent optimizing existing facilities than building entire new ones. That being said, I’m sure if Uncle Sam started handing out free money we’ll all trip over each other trying to get our fair share More on reddit.com

If you had a refinery that functioned perfectly well refining cheap heavy oil, would you spend a billion dollars just to convert it to process more expensive light crude? Not to mention the amount of time it would take to convert it, where you cannot process oil and are losing money. More on reddit.com

June 22, 2026ELI5 "Why does the US import so much oil when they are the world's largest exporter of it?"
It does use what it produces. It also exports what it produces. Whoever you heard that from either misunderstands the situation or is reliant on outdated information. The US has always imported a lot of crude oil to refine and export. Historically US refineries have had a lot of excess capacity which positioned it well to import crude and export refined products. This is a value-add industry since the refined products are more valuable than the crude. The US at one time consumed more crude oil than it produced. That has not been true over the last decade or two. The idea that the US consumes more oil than it produces is left over from the high oil prices and shortages due to the OPEC oil embargo in the 70's when that was true. US policy has focused on "energy independence" ever since. The US is huge. It doesn't make sense to ship oil from Alaska to the east coast to refine. As a result, the US tends to export crude from Alaska to Asia and imports crude from South America/Canada to the East coast. More on reddit.com

Answer (1 of 5): There is no lack of refineries in the USA. US Refineries can refine heavy crude. It is more common for US Refineries to process heavy crude than light fraction crude.

I'm aware of several refineries that have added crude distillation and sat gas processing capacity specifically for this reason. I'm not aware of any refineries reducing coker capacity; there would be no point to cutting production of heavier feedstocks so long as it's profitable.

Can someone please ELIF (explain like I'm five), why the US exports most of its light sweet crude and imports heavy sour crude? I know US refineries are geared towards refining heavy sour crude but wouldn't it make financial and national security sense to give those refineries a massive tax break to convert their refineries?
We could be truly energy independent and stop wasting our blood and treasure in the Middle East. What's the hold up? Considering the trillions we've spent on wars in the Middle East, we could have rebuilt just about every refinery in this country by now.

Oil companies can buy Canadian crude for refining with a $10-$20 discount And sell their light oil at the world price It’s all about the profits

Basically, it comes down to technology and profits. US Sweet crude is high-quality and very easy to refine. It is also expensive. Sour crude is much harder to refine but is cheaper. USA has the technology to effectively refine the cheaper crude for gasoline, diesel and jet fuel while other countries/regions don’t have (or really, haven’t invested in) the tech for the heavier crude so they buy USA’s more expensive but still easier to refine sweet crude. So, US companies sell their higher-priced crude and buy the cheaper sour crude and make essentially everything we need from that. The difference in price between the 2 is called the “crack spread” and it is profitable. I agree w you though…from an energy independent perspective, that makes the most sense but from their prospective, doing it this way makes more cents.

How much oil does the United States import (and why)? | American Fuel & Petrochemical Manufacturers
Many refineries need heavier crude oil to maximize flexibility of gasoline, diesel and jet fuel production. Today, most crude oil produced in the United States is light, including much of what’s produced in the Permian and Bakken.
