on friday im picking up my new baby, a 03 stratos with an 03 225 ho. my boss was telling me that when its cold out i have to run a special oil through the motor, becuase the cold makes the traditional oil thicker and dosent inject right. he has a 175 ficht. i know nothing about oil, as i was just going to run the johnson/evinrude oil that you can buy at the stores. he says to use hd100 instead of hd 40 when its cold. so what does that mean...
