I read up on the threads and decided that
1. I will switch to sythetics
2. I will wait till 10K miles
SO at 10,500 miles, I changed my oil to Mobil 1 (5-30) and to the PureOne (purolator) oil filter (previously on Valvoline and Bolsch filter).
I plan to change oil and filter every 5K miles.
Definite smoother start; before I had to wait a couple of cycles, now it's almost instantly catches (and it's been 30-40 degrees F) lately.
And it "feels" smoother overall to drive. this may be fictional, to justify the higher costing oil, but I like to think I can notice the difference.
Next up are synthetic gear oils...
