Renew control arm bushes with nolathane or urethane (for front wheel drive) and get a wheel alignment
Replace timing chains or belts
Renew carburettor
Renew exhaust system - get extractors instead of a manifold
Ensure engine mounts are new and preferably get nolathane
Ensure all tyres are pumped up to about 32psi

I have an early model Magna and cut down my fuel bill by at least 25% by doing all of these things - the first one being the most useful.   [guest]

Nulon Fuel System Cleaner for EFI and carburettors is an excellent additive to clean out your fuel lines and EFI/carbie chambers. After I used it, the car was much more responsive to acceleration as it removes carbon deposits that affect fuel flow.

Another way to improve the general performance is to go on a long (~250km each way) trip every 4 or 5 months. It's good for the engine to travel over 100km/h for an extended period every so often - this has been widely recommended by mechanics for many years.   [guest]

Fuel system components: Be especially careful when changing fuel system parts. If you already have an electric fuel pump in the tank, do not install a manual fuel pump at the cylinder head (with an arm into the camshaft) as you will waste fuel (losing up to 80km per 60 litre tank). Use the original fuel cannister (without the pump arm) supplied with the vehicle when it came out of the factory.   myxlfidian (150)

Pump it up: When you can, walk. If you can't walk, cycle. And if you can't cycle, try public transport. But if you have to use your car, make sure to keep your tyres properly inflated. It is estimated that up to 80% of tyres are underinflated, which can increase fuel consumption, and therefore also emissions, by up to 5% - as well as increasing wear and tear.   myxlfidian (150)
