I also have a Mobil 1 filter, along with the Bosch oil filter to use in the future, but just might try the Napa Gold, like you have....

Whereas, when the oil is cold (perhaps due to higher viscosity) oil is being held in the hydraulic tensioner longer and pressure build up is seemless.
I noticed that if I turn the key without starting 2-3 times (did it to intentionally to move the pulleys a bit) when I actually start chain rattle was severe which never happens on daily normal start. I concluded that when I ran the motor w/o starting oil in the tensiners were being drained and w/o actually running were not replenished w/ system pressure. Just my theory.

Either am I, but what you are saying makes sense to me. I have to go out soon and will take the Z to run my errands. Will report back later. The Z has sat for 2 days, so we shall see!!!
