[header] How to oil a saddle [title] Warm the oil. [step] Before you begin oiling your saddle, be sure to warm your oil. The oil needs to be warm (at most 100 degrees fahrenheit or 38 degrees celsius), but not hot. 
Hot oil can cook your leather and ruin it. In order to guarantee that it's the right temperature, try soaking it in lukewarm water for about 20 minutes.
