I didn't have any difficulties with the motors, but the reviews say it works, I use it for prevention

My multiple sets of 0802 motors have some that are prone to buzzing and squeaking at times. The bushings are good, but not as good a ball bearings, but on something so tiny, it had to be done. This oil really helps lubricate the bushings and helps them spin smoothly. Definitely notice a difference and brings ones I thought were dead back to life! Obviously works for any size motors, I have used on my 0804, 1102 and 1202.5s also with good results 👍🏻

A squeak no more! Flushed out any dirt or grime that previous was making a high-pitched noise during flight.
