So after many years of changing my own oil, I have an ear for that noise a car makes when it starts, for that first time after an oil change. I have never been a "charge the filter with oil" guy, so for just that split second, on that first startup, you know you are getting an engine start noise that just doesn't quite what have it wants. I think.
Anyway, most cars really don't sound any different on that startup, you never even notice, noisewise, the engine starting without a previously charged system.
But the Altima does. Didn't notice it during first 600 miles prior to swapping out FF, but I've been listening lately during normal startups because there is just that rough grumble for a split second before the engine immediately quiets. So today I changed the oil, and listened more carefully then usual on startup and yep....for just a split second you get the same noise, so I figure that's it. What I actually LIKE about this noise is for oil testing. Does it only happen on certain oils? Filters? Temperatures or combinations of all 3?
Like I explained elsewhere, I think we have a mental defect, because now I'm going to run around, changing oils for test combinations of oil, filter and temperature until I determine the one that works the best, and then that will be the "best" for this car.
