Shaktiman, you ever overhaul a motorbike engine? After putting together most of it, you pump in or pour on a load of oil. Here in India we mix kerosene with the oil. Lubricant and slight solvent/abrasive. Then you keep cranking the thing over for a long, long while. Then clean up and start with fresh oil, not mixed with anything (except maybe beer). For the first x thousand miles or kilometres, you don't go faster than whatever is recommended for each gear. Same with jeans. Damn sight more comfortable after a few washes than when new. I say all this to keep from salivating over the MP which I shall never be able to afford. The post may be pointless, but this is not: shrinks call it displacement.
