Hello, looking for some advice if any found a good “run time” to refill smoke fluid? Say a legacy engine that you fill up Originally per the manual, says 20 drops, when refilling....is it an hour of run time or 20 minutes before I should refill with 5?-10? drops? Just trying to get a gauge so I don’t ever run in empty/dry. Also does time effect refill or just run time? As in say it sits a week without running but it had fluid added at the last run which was say only 10 minutes or something. So short run time but it sat.
Thank you in advance for your help and input.
