Where were you when I got my car? You seem to be a very disciplined person.
:...but also being careful not to "lug" the engine with too low an RPM from being in too high a gear.
Not a chance.
:It is also very important to vary the RPM. Otherwise, the engine will tend to take a "set" at a certain RPM if you drive long periods at a steady RPM with a new engine. It's sort of like taking a "memory", the engine will get used to only that RPM and not be as comfortable at others. Also gently accelerate and decelerate from time to time as this "loads" the ring pack on both sides. Gently rev it up, but then let it naturally rev itself down by taking your foot totally off the gas, to put backpressure on the ring set. This helps the rings to seat better!
When I got my car, I knew I was supposed to, but never did understand why. Thanks for putting into a language for the unmechanical person can understand.
...so at 2,500 miles, I changed the oil and filter with the "Topsider" to Redline 10-40 synthetic. Others have argued that you need more miles before switching to a synthetic, but I felt my rings were fully seated and they were!
Given my ignorance in all this engine stuff (yeah, I know - I don't know squat about engines, but I probably speak for many others like me) why is it smart to wait before synthetic is put in?
