That much dilution late in the game would tend to (1) to extend the FSS interval as well as (2) favorably skew the resulting data in the oil analysis.
Absolutely Greg, and all I told them was that I added 4 quarts since the last known oil change. I did not point out that those were during the last ~2000 miles. Right again Robin! (1) For every fresh quart I added, the FSS jumped back 1000 miles exactly; it therefore said I had 4000 miles to go when I had them do the change and the "B" service. (2) The oil had
to look a lot better under those circumstances.
Re: the silicone, I don't know if that might be part of a compound in the techroline; hopefully the lab knows if it could be found in Mobil1's base pack of additives, did you happen to ask them about that?
As you can see, they were unclear as to whether, or not, the Techron contributed to the Al and Fe elements. They did not mention anything else, so that leads me to believe they don't know the Chevron "secret formula". And no, I did not ask them, nor did the guy make any mention of silicon. If anyone here is that curious, I'll gladly call them back and ask.
How many oil changes have you owned your car? Your last post suggests this is the first oil change since you've owned it, so it would be interesting to see if silicone shows up in the next one. For some reason I thought you'd had your car for a few years.
This is the 1st oil change since I bought the CPO car w/53,000 in June, 2006. I have (what I believe to be) the complete service history, and only once was it serviced w/o regard to the FSS interval. What I don't know are what services were performed at the time.
Lastly, you've been holding out on us: you have friends!??
Take care and enjoy the ride, Greg
