BT, I would also like to know the mileage since the conversion however not because I don't believe in the technology; I do. The reason for no oil changes...well...
the moving parts most effected by extreme heat in a conventional engine are the (poppet) Valves and related components in the Cylinder Heads, followed by the Piston Rings and Pistons in the Block. These obviously require sufficient oil and, taking into account both the viscosity and the heat communication between the moving parts, oil changes are a must because, as we know, oil breaks down as it cools, cleans, and lubricates.
The Coates Spherical Rotary Valve (CSRV) system does not require oil in Heads (the hottest and dirtiest section within the conventional engine), therefore the oil does not break down as quickly in the Block as it performs it's three vital aforementioned functions.
Having said that, please also note that oil change intervals were "recommended" by auto manufactures. Why, well I would argue, more service visits for one thing! I recommend everyone to google "consumer reports ny taxi oil changes". Since reading that article when it first came out, I've only change my (conventional) oil every 7.5-8K and I had a Toyota PU with over 350K miles on it before Old Man Winter and I totaled it on the Mass Pike. In that vehicle I only went through 2 Head Gasket sets, a water pump, and two timing belts. So 50K between oil changes IMO is believable.
Which brings me to my reason for wanting to know the miles. I mentioned the moving parts most effected by heat, however the non-moving part most effected is of course the Head Gasket; a very costly repair to most. I would like to know how many miles the Head Gaskets on the Mercedes have withstood the pressure since the heads were replaced with the CSRV heads around 80K (I guess around 80K because the tests were performed after 81,281 miles per the newly released documents).
After reading the test results and substantiating documents, I am thankful that George releasing them, albeit in his PR challenged way. I grew tired of reading the constant bashing of many on the other sites and I'm glad he gave the longs a little ammo. Here, thoughtful people with good questions, such as yourself with yours, engage in meaningful discussion in hopes to provide answers and insight since George keeps a lot of details within the walls of the NJ Plant. Cheers, GLTA!
