Starting Day 1 of changing to the first time use of Amsoil 5w30 on a 2003 GMC Sierra, with a 5.3L engine and 78,000 miles, I now have an Engine Oil leak.
It is coming from some midpoint in the engine on the passenger side and leaks about a 3-4" Diameter spot each night.
This truck has never leaked a drop before day 1 of the Amsoil!
It has used Dino, M1 Syn, Pennzoil Platinum and M1 EP (all Synthetics for the last 3 Oil changes...) with not a drop of leaks.
Can anyone offer advise on this, including Pablo...???
Thanks...
