BlackStone Comments: All wear continued to look good in the latest sample from your Ranger. Steady wear trends like these portray an engine in good health that is operated and maintained well. Universal averages are based on an oil run of 4,800 miles. You could have easily gone that long on this oil. The oil was in good shape physically, containing no moisture, fuel, or coolant. Insolubles were low at 0.2%, showing good oil filtration. Silicon improved to 7 ppm so your air filtration/induction system is working
well, too. At 54,210 miles this 4.0L is wearing very well!


I've been running GC for about 4 OCI's now and the numbers have steadily improved and now, I believe, flat lined and are remaining steady. Although there isn't much to talk about on BITOG about this UOA, I'm liking the boring. Excitement is usually not good.

Yea this is really an excellent report when you look at the flashpont and filtration. Its obvious you could run this out twice as far and the numbers would be really good.

What oil filter was you using on this OCI.
I have a 4.0 in a Ranger and just changed to the 0-30-GC and a Motorcraft filter. Mine has 115,000 miles on it.

Run the next fill to 7500 miles and see how it performs!!

Nice report.

Black Bart, I'm using a NAPA Gold 1372 I think the number is. Is your 4.0 a pushrod engine or a SOHC?

I'm not going to run it 7500 on the next OCI as it will temporarily be the last GC fill as I have found another oil I want to try. I always run 4K miles on an OCI so I can have a good comparison with the other oils I run. This truck also sees very similar loads, operating conditions and commutes so it is the best vehicle I have for a real world test bench.

My truck is a 2000 and it is a pushrod engine.
I have three vehicles with this engine and no problems with any of them.
