Fuel Type:
Premium Unleaded Gasoline
Crash Testing:
Modern crash safety standards were not as prevalent or standardized as today; however, the W113 featured a relatively strong safety cell and crumple zones for its era.
Brakes:
Four-wheel disc brakes (standard on 250SL and 280SL, front discs on 230SL); Power assisted braking system.
Body Structure:
Designed with safety in mind for the period, including a reinforced passenger cell.

Curved, shatter-resistant glass for the iconic 'Pagoda' hardtop.
Oil Change:
Typically every 3,000-5,000 miles or annually (refer to manual for specific recommendations based on driving conditions).
Tune Up:
Regular tune-ups including spark plugs, points (if applicable), filter replacements, and fluid checks at intervals specified in the manual.
Engine Oil:
Refer to manual for specific viscosity grade (e.g., SAE 20W-50 or similar, depending on climate). Manual will specify Mercedes-Benz approval codes.
Transmission Fluid Auto:
Specific ATF type (e.g., Dexron II or equivalent, as specified by Mercedes-Benz for the period).
Brake Fluid:
DOT 3 or DOT 4 brake fluid (refer to manual for precise specification).
Body Corrosion:
Prone to rust in common areas like wheel arches, sills, A-pillars, and around windows.
Fuel Injection System:
Bosch mechanical fuel injection can require specialized knowledge for tuning and repair; seals and hoses can degrade over time.
Suspension Wear:
Bushings, ball joints, and tie rod ends can wear, affecting handling and alignment.
Automatic Transmission:
Can develop leaks or shift quality issues with age and mileage; internal components may require rebuild.
