Summary of corrosion rates as measured by linear polarization resistance showing the effectiveness of the inhibitors synthesized.

Oil	Uninhibited corrosion rate	Inhibited corrosion rate	Inhibitor efficiency (%)	Corrosion rate reduction ratio
Cress seed oil amide	2.0 ± 0.4 mmyr^−1; 81 ± 16 mpy	8.3 × 10^−3  ±  0.008 mmyr^−1; 0.2 ± 0.01 mpy	99.6%	241
Linseed oil amide	1.45 ± 0.005 mmyr^−1; 58 ± 0.2 mpy	0.025 ± 0.015 mmyr^−1; 1 ± 0.6 mpy	98.3%	58
