Never true. The sum of an odd number and an even number is always odd, but all multiples of 6 are even numbers.

Explanation

An odd number plus an even number always gives an odd number (odd + even = odd). All multiples of 6 are even numbers (6 = 2×32 \times 3, so every multiple of 6 has 2 as a factor). An odd number can never equal an even number. Therefore, the sum of an odd and an even number can never be a multiple of 6. For example, 3 + 4 = 7 (odd, not a multiple of 6), 5 + 8 = 13 (odd, not a multiple of 6).
