Here are the results from the first UOA on my 2006 Dodge Charger with a 5.7 Hemi. It'm my wifes daily driver that saw almost 20K in it's first 10-11 months. Primarily highway with a Fredericksburg, VA to Buffalo, NY round trip just before the sample.
History of vehicle:
Bought new off dealer lot in early 2007 with 300 miles.
Changed factory fill at 1200 with M1 5-20/Wix
Changed again at 5250 with M1 5-20/Wix
Changed at 11,500 with Amsoil ASM 0-20/Wix (this sample)
I drained the ASM and replaced it with ASM and Wix filter(this time a oversized Wix 51515).
Oil had 8580 miles and vehicle had 20,080 at time of sample.
My results are on the left and univeral averages on the right. Note - I had a AFE CAI on since I got the vehicle and it wasn't cleaned until after the sample (compressed air - I haven't truly cleaned and re-oiled it yet but I will in the coming days)
I used 1/2 quart of make up oil at about the 5K mark and another 1/2 quart at 7K.
I'd like to do 10K OCI's on both of my vehicles form now on. Both see 15-20K per year.
Comments: HAROLD: No problems were found in the first sample from your Charger. Universal averages, for this type of Dodge,
are based on an oil run of 4700 miles. You've run your oil longer than that and wear was about where it should be. The
TBN read 4.2 so you had plenty of active additive remaining for the extra miles. The viscosity was fine for a 0W/20 and
no fuel, coolant, or moisture was found. Insolubles were low, so your oil filter is doing a good job. Try going 9000-9500
miles on the next oil. Copper should still improve, even with the longer oil change.
