My 2001 CRV SE has 297,657 miles.
Original engine, original transmission, original head gaskets.
Her bones rattle a bit, but her motor still purrs.
Type of gas used: anything, anywhere except diesel.
Type of oil used: any type of motor oil.
I do change all the fluids every 2 years - differential included.
Oil changes, once per year.
Spark plug, wires, and distributor cap change every 5 years.
Timing belt change every 100,000 miles.
Tire and brake maintenance as needed.
That's about it.
It's a shame the new ones look like miniature eggs.
She's a fantastic car.
