on my b&w hitch i have to pin open to back into trailer, when it was new i did not have to do that, now that i have many miles on it i have to pin open , wish i didn't have to pin it open . i'm keeping this hitch ..
had to many times, used moible oil or exion oil , start using oil, changed to castrol 10 w 30 is the one to use & made a big diffrence in oil useage , have been told by others have done the same , it does make a difference , wont hurt to try.
change oil to castrel 10w30 reg oil & ac delco filter , has same problem with 2000 7.3 using mobile oil 1 qt every 1200 miles then went to 2100 miles to quart ..
