A 24cc 2-cycle pre-mix engine manufacturer recommends 50:1 mix when using synthetic oil. What ratio should I use when using AMSOIL 100:1 pre-mix oil, 50:1 or 100:1?
AMSOIL Synthetic 100:1 Pre-Mix 2-Cycle Oil is recommended for use at a 100:1 mix ratio in normal service applications where 50:1 to 80:1 are recommended. For severe duty service such as racing applications and for hot operation industrial motors that run for extended periods of time, richer mix ratios of 50:1 to 80:1 are recommended.
