Take the tour ×  The other time I asked my mechanic, are my
tyres about needing to be changed?  He said, naw, another 8000
miles. After driving 7000 miles, I asked another mechanic who
again said, long way to go.  Does hyper-miling reduce the stress
on the treads of my tires and ultimately the question - does
hypermiling reduce the stress on engine oil?  I included the
description of my tyres to illustrate the possible effects of
hypermiling. I have a manual stick-shift. I don't hypermile
compulsively like hybrid car drivers. I hypermile by giving
adequate distance between myself and the truck/car in front of
me to allow me to slow down. I accelerate gradually. I cruise to
red traffic lights. And I do drive a lot across states to get 40
- 45 mpg out of a stick-shift Honda Civic.  So, after 7000
miles, my engine oil is still viscous and golden in colour but a
little dirtier. Could I say that the molecular integrity of my
engine oil can be correlated to its viscosity and goldenness?
Should I change the engine o
