How do I use after run oil?Надеюсь перевод не нужен
Take off the air filter and glow plug, and drop about 5 drops of after run oil into each opening. Pull the engine pullstarter a few times, or rotate the flywheel several complete rotations (pull the pullstarter spring or turn the flywheel on a starter box) to cycle the oil throughout the engine's internal parts. We highly recommend using after run oil on any engine that you do not plan to run for more than a week.
You can also use Marvel Mystery Oil (US brand oil), 3in1 brand oil (US brand oil), or automatic transmission fluid as a substitute.
NOTE: Do NOT use a lubricant like WD-40 on the internal surfaces of your Nitro car engine! It is not designed for use inside 2-stroke engines. Also, DO NOT use any oil that contains silicones."
Хотя траксас уверяет, что после покатушек можно прыскать ВДшкой....
P.S. На форуме это уже не раз обсуждалось
