You're standing in the aisle at Walmart. Your eyes dart between a $30 bottle of artisanal, cold-pressed nectar from a boutique grove in Tuscany and the massive, plastic jug of Great Value 100 extra virgin olive oil that costs less than a fast-food lunch. It feels like a trap. We’ve all been told that if olive oil is cheap, it’s basically lamp oil flavored with chlorophyll.
But is it? Honestly, the "olive oil mafia" stories you’ve heard—about how 70% of EVOO is fake—are a bit outdated. A lot has changed since those 2010 UC Davis reports went viral. Retailers like Walmart have actually stepped up their quality control because nobody wants a class-action lawsuit over mislabeled fats.
I’ve spent the last month cooking with this stuff. I’ve drizzled it, fried eggs in it, and even did the "fridge test" (which, spoiler alert, isn't as reliable as TikTok says). Here is the reality of what you’re actually getting in that Great Value bottle.
The Truth About Great Value 100 Extra Virgin Olive Oil and Quality Standards
Most people assume "Great Value" means "lower quality." In many cases, sure. But with Great Value 100 extra virgin olive oil, Walmart is playing a scale game. They aren't growing their own olives. They are sourcing from massive conglomerates that aggregate oil from Mediterranean regions—think Spain, Italy, Greece, and increasingly, Tunisia.
The label says "100%," and legally, that matters. For an oil to be labeled "Extra Virgin," it must be extracted through mechanical means without heat or chemicals. It has to meet specific chemical parameters, specifically an oleic acid acidity level below 0.8%.
Does Walmart hit this? Usually, yes. But here is the nuance: "Extra Virgin" is a range, not a single point of quality. You have the high-end oils with acidity levels around 0.2% that taste like a peppery explosion in your throat. Then you have the budget-friendly stuff like Great Value, which sits closer to that 0.8% limit. It's technically EVOO, but it's the "entry-level" version.
It’s fine. Really.
Understanding the Sourcing Map
If you flip the bottle around, look at the back. You'll see a string of country codes. Spain (ES), Italy (IT), Tunisia (TN). This is a blend. Blends aren't inherently bad, but they are designed for consistency rather than character. Walmart wants the bottle you buy in Seattle to taste exactly like the one in Miami. To do that, they mix oils to create a neutral, predictable profile. If you want "terroir"—that specific taste of a Sicilian hillside—you won't find it here. You’ll find a reliable, mild fat that doesn't overwhelm your food.
Why the Price is So Low (It’s Not Just "Fake" Oil)
People get suspicious of the price. How can they sell two liters for the price of a small bottle of California Olive Ranch?
The answer is logistics.
Walmart moves more volume than almost any other retailer on earth. They buy in such massive quantities that they can squeeze the margins of the suppliers. Also, the packaging. That clear plastic bottle? It’s cheap to manufacture and light to ship.
Wait. Clear plastic?
That’s actually my biggest beef with Great Value 100 extra virgin olive oil. Light is the enemy of olive oil. It causes photo-oxidation, which turns the healthy polyphenols into rancid, soapy-tasting junk. When you buy the premium brands, you're paying for dark glass or tin that protects the oil. When you buy Great Value in plastic, the clock is ticking the second it hits the fluorescent lights of the grocery store shelf.
If you buy it, grab the bottle from the very back of the shelf where it’s been in the dark.
Performance in the Kitchen: Smoke Points and Sautéing
I tried searing a steak with it. I also made a delicate lemon vinaigrette.
For the steak? It was great. There's a persistent myth that you shouldn't cook with extra virgin olive oil because of a low smoke point. That's mostly nonsense. Most EVOO has a smoke point around 375°F to 405°F ($190^\circ C$ to $207^\circ C$). Unless you're doing high-heat stir-fry in a wok, you're fine. The Great Value version actually holds up well here because its flavor is already fairly neutral. It doesn't get bitter when heated like some high-polynphenol oils do.
For the vinaigrette? It was... okay.
It lacked that "zing." If you're used to the peppery finish of a high-end oil, this will feel flat. It’s buttery and slightly grassy, but it doesn't have that back-of-the-throat kick that signifies high antioxidant content.
Basically, use the cheap stuff for:
- Sautéing vegetables.
- Roasting potatoes.
- Making mayo or pesto where other flavors dominate.
- Baking (it's a great sub for butter in cakes).
Save the expensive stuff for:
- Dipping bread.
- Finishing a soup.
- Drizzling over fresh mozzarella.
The Health Reality: Are the Polyphenols There?
This is where things get tricky. We buy EVOO for the heart-healthy fats and polyphenols like oleocanthal. These compounds are anti-inflammatory.

In a study by the National Center for Biotechnology Information (NCBI), researchers found that polyphenol levels drop significantly as oil ages or is exposed to light. Because Great Value 100 extra virgin olive oil is a mass-market blend often sold in clear plastic, it likely has a lower polyphenol count than a "fresh-pressed" single-estate oil.
It’s still healthier than soybean oil or highly processed "vegetable oil" blends. You’re still getting the monounsaturated fats. But if you’re drinking a tablespoon a day for strictly medicinal reasons, you might want to invest in a brand that lists the harvest date. Walmart’s bottle usually only lists a "Best By" date, which is a bit of a shell game. An oil can be "best" for two years, but it’s most nutritious in the first six months.
The Fridge Test Myth
I mentioned this earlier. Some people say if you put olive oil in the fridge and it doesn't solidify, it's fake. This is a total old wives' tale. Some perfectly pure oils don't solidify because of their specific wax content or the variety of olive used (like the Arbequina). Don't judge your Great Value bottle based on whether it turns into butter in the cold. It’s not a scientific metric.
Red Flags to Watch Out For
Even though it’s generally "safe," you should still use your senses.
- The Smell: Open the bottle. It should smell like grass, tomatoes, or even just "clean." If it smells like old peanuts, crayons, or sweaty gym socks, it’s rancid. Take it back. Walmart has a generous return policy.
- The Taste: Take a small sip. If it feels greasy and leaves a film on your tongue without any fruitiness, it’s likely old.
- The Date: Always look for the furthest date out. If the bottle expires in three months, it’s been sitting on that shelf way too long.
How to Make Cheap Oil Taste Expensive
You can actually "hack" your Great Value 100 extra virgin olive oil to make it punch above its weight class.
Since the base oil is neutral, it’s the perfect canvas for infusions. I like to take a cup of it, heat it very gently with three smashed garlic cloves and a sprig of rosemary, then let it cool. Suddenly, that $8 jug tastes like something from a specialty shop.
Store it in a cool, dark cupboard. Not next to the stove! The heat from your oven will kill the flavor faster than anything else. If you bought the giant 3-liter tin or jug, decant a small amount into a dark glass cruet for daily use and keep the rest sealed tight in the pantry.
The Verdict: Is It Worth It?
Honestly? Yes.
If you are on a budget and trying to eat a Mediterranean-style diet, the Great Value 100 extra virgin olive oil is a massive win. It’s a million times better for you than refined seed oils. It’s versatile. It’s predictable.
It isn't a luxury product. It’s a utility product.
Don't let the food snobs make you feel bad for buying it. Just be smart about how you store it and what you use it for. If you’re making a salad where the oil is the star, maybe splurge once in a while. But for everyday cooking? This bottle is a workhorse.

Actionable Steps for Your Next Trip
- Check the Back Label: Look for the "Product of..." section to see which countries are in your specific blend.
