I have found that my oil is not getting hot enough. It is like pudding, no engine water problems, but water temp never gets higher than 110. I have oil temp of 120 130 the must on both engines. I have 502 500 HP VI 1999. What is the stat at the oil filter block set at and is it changeable to a higher temp?. I know I need higher temp but not sure how to get it. I believe I should have 180 oil temp? Any help or answers.
