I have 2 different situations that I am thinking might be useful to obtain an engine oil analysis.
The cost is $40
I have recently placed an older (quality) rebuilt 4.2 in my 420G, its use since rebuild is unknown
The other engine is in my 4wd , and has 335,000km, obtained by me with 280k on the clock
why I am considering this is it is the best way of detecting any failures that allow mixing of oil and coolant, or combustion gases. Often (imo) an engine will function for a long time without giving clear and obvious signs, but it is killing your engine
detects the presence of various metals in your oil, that are telltale of excessive wear in bearings, rings, etc
detects dilution of oil by fuel (can be problem with our older vehicles)
to make it most worthwhile, it would have to be done semi-regular
here is some blurb…anyone done this…think it worthwhile?
