19 months and 10,065 miles of use got me these results. According to average speeds from fillups, fuelly is saying I do 2/3 highway and 1/3 city driving. I usually drive at very low rpm except when accelerating, and I shut the engine off when I am going to be waiting at a stop light for more than 15 seconds. As of lately, probably the last thousand or so miles in this oil change I got an engine block(coolant) heater and have been preheating the car before starting it. Yes, even when it is 85 degrees outside I still use the heater. The engine will idle at 1000 rpm cold, or 700 rpm if preheated, and it runs smoother when preheated as well!
At around the 7000 mile mark I had to add a quart of oil, I had an oil pan and drain plug leak that were fixed after this oil change, so I may not have to add any oil this time around.
Here is what Blackstone had to say:
"We're not sure how the TBN would've read without the added oil. Probably lower, but it's hard to say how much. In terms of metals, only aluminum (pistons or bearings) is a bit elevated. Iron is high, but since it accumulates with use, this level is fine for the mileage. The TBN's good at 2.5, and no contamination was found. Let's see how aluminum looks after 11,500 miles."
