Want to make you car engine last as long as a 1.1 or 1.2 miooion mile truck?
1. Get fanatic about air filtering...big money, big systems, very complex and very effective and very maintenance intensive. (and fuel filtering)
2. Don't shut it off... If it keeps running, it will not "land" on any metal and will not show wear.
3. Get religous about
oil changing and particulate (gas spectrum samples analysis of the
oil to discover various failutes of
oil, filters, fuel filters, valve guides, bearing journals, rings, piston skirts....before they cause engine failure or premature wear.
4. Build it loose. Big spaces allow big dirt, efficiency isn't affected until rings or guides gap, everything else wants lots of room. (That's why Ferrari's smoke...guide wear(clearances) that tolerates high rpm.)
5. Build from unobtainium materials, the best of the best...design for durability and torque.
6. Keep RPM's low....allows complete burning, lower mep's, least possible ring surface velocity and bearing surface velocities (to stay well within shear strength of oils)
7. Design unique transmissions for low rpm inputs with 18 gears in the hi-range...
And lots and lots more. Who bloody cares on a Cobra? 5000 miles a year max?
