Your owners' manual for your 1941 Chevrolet Sedan (see attached picture). Obviously the technology of antifreeze design has improved since then. Your country will have it's own laws about the composition of coolant allowed. Any recommendation you receive from this website (Stovebolt.com) may not apply for use in Germany. It is your responsibility to investigate for yourself. We at Stovebolt care but we can only give information on what is allowed in the USA.
I found this on a website. It has merit but it's also funny. A designer antifreeze:
Best Antifreeze for All Vehicles: Preston All Vehicles Antifreeze/Coolant Best for Asian Vehicles: Peak Original Equipment Technology Antifreeze Best for GM-Approved Vehicles: Prestone DEX-COOL Antifreeze/Coolant Best for BMW Owners: BMW Antifreeze Best Affordable Antifreeze: Super Tech 50/50 Antifreeze Pre-Mix Best Permanent Coolant Leak Repair: K-Seal ST5501 Multi-Purpose Antifreeze Best Winter Antifreeze for RV and Marine: Super Tech RV and Marine Antifreeze Best for Toyota Cooling System: Toyota Long Life Antifreeze Coolant Best for Honda Engines: Honda Genuine Coolant Best Organic Acid Corrosion Inhibitor: Zerex Original Green Low Silicate

"Adding CFM to a truck will only help at engine speeds you don't want to use." "I found there was nothing to gain beyond 400 CFM."
