Premium Unleaded Gasoline (Octane rating as recommended for the specific engine variant)

Oil Capacity:

5 US quarts (4.7 Liters) with filter change (check manual for exact capacity, typically 5 quarts).

Oil Specification:

API SF or SG rated oil (for modern equivalents), viscosity typically 10W-30 or 10W-40 depending on climate and engine condition. Historically, 10W-30 HD or straight 30W was common.

Coolant Type:

50/50 mix of ethylene glycol antifreeze and distilled water.

🔧 Transmission

Type:

3-speed manual transmission (Muncie SM318 or similar).

Manual Gear Ratios:

Varied by transmission option (e.g., Muncie M20 often featured wider gear ratios).

Automatic Features:

Powerglide offered basic automatic operation, generally less performance-oriented than manual options.

Manual Transmission Fluid:

GL-4 gear oil (e.g., SAE 90) or specific manual transmission fluid as per GM recommendations for the era. Synchromesh fluid often recommended.

Automatic Transmission Fluid:

Dexron III/Mercon equivalent (historically, Type A Suffix A or Dexron II was used).
