All results are within normal ranges, and the wear rate per 1,000 miles is below 5 ppm, which is good. The particle count results look great, and the Tin level is from the Molybdenum
additive in the oil. Based on these results, the oil change interval can be extended, so resample at next oil change (3,000 to 4,000 miles) to monitor and establish the trend analysis.
Based on these results, all you need is the standard kit. You will get all of the data as on this report except the particle count. Now that we now there is a low level of contamination in the engine, the standard analysis can give you enough data to accurately determine the proper oil change interval.
I’d recommend taking a sample at each oil change until we dial in the proper oil change interval for you. I suspect that might take 3 or 4 samples to get that well established. After that, an annual oil analysis is all you will need.
This was actually the second oil change with R&P. Lake suggested to wait till the second interval to “double flush” the internals and avoid cross contamination with the previous LiquiMoly oil. So by the time this sample was sent I had actually driven 4K miles in total. (2k - drain and change filter and 2k - drain and change filter and sent oil for analysis)
I am not a member of BITOG and I am totally ok with this being shared over there!
So this is not my oil sample but from another fellow that had posted this on AudiWorld. We were talking about VR&P over there and there are a number of us using it in our low tension oil ring equipped Audi 3.0T engines. I thought it would be great to post it here so I had suggested to him that I could do that for him if he would allow me to and he agreed to allow me to post it here as he is not a BITOG member.
