switched to rotella full synthetic 0w-40 at the last oil change. i have been unable to find 0w40 mobil 1 here in Canada unless I buy it by the case direct from the esso distrubutor so I went with what was available .
Anyway, 700 miles since the switch my main seal/pan arch oil weep is gone . I have had that sincei got the truck 22,000 miles ago: always with a film of fresh oil on and around the inspections plate and a drip forming. The plate is now bone dry. I was very surprised.
On the other hand I have occasional minor start up rattle for the first time since I switched to the small good filter. I was previously using 10w30 and 5w30 mobil 1.
I also have used no oil so far with town, highway and offroad driving, whereas by now with mobil 1 I would expect to be half way down to the add line.
i will monitor the start up rattle but i recommend you try this if you have a seep at the main seal inspection plate.
