I know some people have been curious as to what the Torco does in a sample so I did it with my first GC run. I only used half of the bottle (~6oz.) in this sample. Driving habits have changed considerably with this sample as well. Instead of the 300 miles a week (freeway) I was doing, I am now doing 50-70 miles a week. The sample with in use from late March until mid November, it was able to see the cool spring/fall and the hot desert heat.
Blackstone was the lab of choice.
Jon: Thanks for the note about the friction reducer. We are guessing that is where the extra silicone is coming from in your oil (found, read below). We doubt its abrasive dirt escaping the air filter because wear still looks ok and shows no changes that would indicate poorly wearing (or abraded) parts. The TBN was 0.5 showing little active additive remaining in this oil. We did find some fuel dilution which is common in engines that see a lot of city driving and/or idiling. About 2.0% is the most we like to see so well keep an eye on it in the next sample.

I guess my lunch breaks in the car listening to the radio are needing to come to an end if I want my fuel dilution to stop. Am I correct in assuming this is why my copper wear is up? The moly wasnt as high as I was thinking it would be with what the specs on the Torco were showing. The silicon should be considerably lower in the next sample. The car went down for trans replacement when this sample was pulled. I dropped the oil pan/pump/pickup to replace the front main seal. When I looked in the pickup it was full of some of the silicon that apparently escaped the gasket when I did the oil pan gasket last year. Cleaned out the pickup and pan so all should be good next time. The Baldwin B2-HPG should help at capturing any stray pieces that were too small for me to see.
In all, I believe I should be happy for this result on what is now a 137,000 mile engine.
