What could causes be for a cold start lifter tick? This is a 2008 Silverado with 5.3?
Could it be the oil? Something with better cold pumping properties? I'm currently running PP 5W-30. What about adding seafoam or something to the oil? Is that advised?
I noticed that PP HM has better MRV than the PP (10500 vs 9500). Is that not enough of a separation to make a difference?
Are Castrol Edge and QSUD good choices?
Side note: I did notice that after only maybe 500 I am almost a quart low (more interstate driving than normal) so I want to switch to see if there is another oil that burns less.
