I've heard that most all 351M/400's have low oil pressure (mine is usually below the normal range on the indicator). Is there any way to increase oil pressure or oil flow? I was thinking about lucas oil stabilizer, but have read that it is garbage. Would using a thicker (20W-50?) oil increase pressure and lubricate the engine better? Are there any high volume oil pumps available? I want my engine to last, and the low oil pressure is starting to worry me. Any advice is greatly appreciated.
