Ok so i changed my oil yesterday with max life 10w30 with a wix filter. the prev owner had synthetic 5w20 and he said he put that lucal oil stuff in it. Driving home from work today i noticed sitting at idle the oil would drop slightly above low but go to mid normal to just below while cruising. I know that the stock gauges are crap but this is something it didnt do the day before. I am also in FL so its HOT. just did coolant flush and added some water wetter also.
