My FSS Compared to Oil Analysis Results 1998 E300
When I got my 98 E300, I was intrigued by the FSS and wondered how reliable/trustworthy it was. Most seemed to think it could be trusted and thus be relied upon for oil service intervals.
But I wanted to see for myself. So I changed the oil at 8200 actual miles....the FSS said I was on pace for 14,900 miles. My oil analysis is below.
FWIW the oil analysis tech said he'd be comfortable with a 15k drain interval based on my results. I may be a bit more conservative and drain at 10k, which would put soot at 1%.
Anyway, just wanted to share the results and see what comments anyone had on the data.
