Taste aside, rapeseed oil is rich in erucic acid unless it is made out of canola. Canola is a special low-erucic variety of rapeseed that is safe for consumption in large quantities.
The tolerable daily intake of erucic acid is 7 mg per kg of body weight and the legal limit for erucic acid in canola oil is 2%. This means that an average adult (70 kg) could hit that intake with 24.5 grams of canola oil, which is less than 2 tablespoons for the non-metrically inclined.
