2012 Service Maintenance for the Fairlady:

1. Engine oil change and new Osaka oil filter cartridge (Ultron Rallye 10W-40 Semi-synthetic)
2. Steering box oil change (Conoco 80w-90 GL-5 Semi-synthetic Gear Oil)
3. Grease suspension and steering fittings
4. Clean fuel and air filters
5. Clean and adjust rear drum brakes
6. Body wash and wax
7. Rustproofing underside and body components

I immediately noticed better throttle response and a smoother idle after changing the engine oil. The steering also became lighter after greasing the suspension and steering fittings and replacing the steering box oil with lighter 80W-90 gear oil compared to the 90W gear oil.

Will replace the spark plugs and contact points asap. Next project would be to install tow hooks in front and at the rear of the roadster.
