Place the pistachios in the basin of a food processor. Pulse repeatedly until mixture is crumbly. Set the food processor to blend and blend until broken down into coarse crumbs. You will need to scrape the sides/bottom with a spoon or spatula periodically if the pistachios are not incorporating evenly.
Add sugar, salt, and 1 Tablespoon of oil. Continue to blend until mixture is smooth and creamy.
Add another Tablespoon of oil and continue to blend until well incorporated. If needed, add additional oil, a teaspoon at a time, until proper consistency is reached.
Use as desired.
