Is there experience with this synthetic engine lubricant? I am considering it to replace the motor oil in my BB Chevelle street engine. It has the ability to reduce the engine oil temp 5 to 20 degrees according to the manufacturer. Has anyone noticed cooler engine temps using this product? What about leakage? My seals are tight but can I expect more leak from gasketed surfaces such as valve cover? Any experiences are welcome.

I RUN ROYAL PURPLE IN MY B/B CHEVELLE, MY TWIN B/B
50' BOAT AND THE GENERATOR AS WELL IN THE BOAT, IT STOPPED THE MINOR OIL USAGE I HAD IN THE BOAT, I HAVE NOT RUN MY CHEVELLE ENOUGH TO JUDGE YET(BEEN IN PAINT SHOP FOREVER !)DUE TO GET IT BACK TODAY, BUT I HAVE HEARD THAT BEFORE TOO !, I DID NOTE A LOSS OF OIL PRESSURE IN THE CHEVELLE, IT'S A LIITTLE LOWER THAN I LIKE, DOWN TO ABOUT 25, HOT
IN DRIVE, NO LEAKAGE NOTED IN ANY OF THEM, I LIKE THE STUFF, THE BOAT NEEDED ALL THE HELP IT COULD GET !!!ROB....
