A 1995 Ford Taurus with a 3.8L engine should use
conventional green antifreeze, also known as silicate-based antifreeze. However, it's crucial to check your owner's manual for the *specific* recommendation from Ford. While green is likely correct, using the wrong type could damage your engine. The manual will specify the proper type and concentration.
While you *could* use a newer type like the OAT (organic acid technology) or HOAT (hybrid organic acid technology) antifreezes, it's generally recommended to stick with the conventional green type in older vehicles unless the manufacturer explicitly approves a change. Mixing different types can lead to problems.
