hello i was wondering does anyone use amszoil synthetic in their motors when i owned a truck i ran it in my trans and rears cause loaded pulling steep grades the temp still stayed cold when everyone else on the radio was saying they were getting really hot. also i know they did a study put in a motor and didnt have to change the engine oil for 400,000 miles or more just did a oil analysis at regular changes of the filter and replaced filter and oil it took for that. seems that would help to keep engines to run cooler. and i know i tried to get a fire going one time when i got it started i threw some of this oil on it just like putting water on it because of the flash point. just wondering
