Amsoil Oil filter half full or half empty
I am using Amsoil series 3000 synthetic 5w30 and the Amsoil SDF
oil filter. I changed the filter only at 5,000 miles and was surprised it didn't make a mess. It was only half full of oil. Is this normal? Do other filters also let oil siphon back out when the truck is not running? Is this related to my 24 valve engine? The pressure seems to come up soon enough when the engine is started. Thanks in advance.
