For fuel economy we:
- walk and bicycle whenever possible
- Mobil 1 synthetic motor oil--at 215,000km the '93 3.0 litre engine does not leak one drop of oil
- 4 season M&S Michelin LTX 6-ply tires for wall strength and reduced rolling resistence (In my experience, 99.5% of people who buy AT tires DO NOT NEED THEM!!!)
- tires are filled to 34-36 psi, well beyond what Nissan calls for (27 psi) , and well under the potential full pressure of the tires.
- highway speeds reduced from 110-115km/hr to 95-98km/hr (the ride is much, much quieter) That is a circa 20% reduction in average highway speeds.
