Mobil 1 - Constant oil leaks on a new truck??

[Ramblin Fever]

Could the possibility be also that the truck is not driven enough to keep the seals working correctly?

I know we had a Toyota truck that we put all new seals/gaskets on and then it sat for almost 3yrs with the exception of being driven maybe 3-400 miles a month - that's probably stretching it.

Anyhow, when we truly put that truck back out on the road for daily duties she started leaking everywhere - almost broke down and thought about replacing everything again. However, we waited a bit, and about 3-4 weeks later the rear main seal completely dried up, along with the oil pan.

This particular truck has never seen a single drop of synthetic oil in it's life.

I thought the same myself with it only being driven on the weekends.

Our 300 mile trip today may have proved that wrong. All interstate driving. It leaked a good amount.

I think its a seal failure. It's leaking for sure around the oil pan, rear main most likely, and for sure @the oil pan adapter.
