Is Peanut Oil Acidic or Alkaline?
Peanut oil (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Peanut oil is pure fat with no significant minerals, so it sits at 0.0 and is neutral. Unlike the peanut itself, it contains no relevant amounts of protein, phosphorus or potassium. What you fry in it decides the direction: vegetables stay alkaline, meat doesn't get milder just because oil is involved, and 899 kcal per 100 ml come on top.
In the Oils & Fats category, peanut oil (raw) ranks #6 of 22, sorted from alkaline to acid-forming. More alkaline options include Sunflower oil (0.0), Sesame oil (−0.2), Margarine (−0.4). More acid-forming are Safflower oil (0.0), Coconut oil (0.0), Flaxseed oil (0.0).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is peanut oil acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Peanut oil (raw) has a PRAL of 0.0 per 100 ml, so it counts as neutral in your daily acid-base balance.
Does peanut oil count in the acid-base balance at all?
Hardly. At 0.0 per 100 ml, peanut oil is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
