My crap ass 4g18 waja use leftover oil collected scrap oil bottle, I mix it with whatever i can find, janji is oil inside has 0w20, 5w20, 5w30, 5w40, 10w40, 15w40, 10w60, differential oil (75w90), motocycle 4T oil, Porsche PDK oil and a little bit of ATF

Then inside the power steering also got a few different kind of ATF fluid, the original whatever fluid which i dunno what that came from previous owner, then i added toyota AT WS fluid, Toyota Type IV, Ford Mercon V, toyota CVT FE, Dexron III, some dunno what multivehicle ATF, LubeGard Seal Fixx (Yeah is leaking big time that why ), some old KIA / Hyundai ATF (which i drained from scrapped transmission oil cooler ). Somehow after using the seal fixx the leak had stopped entirely now i will just change it like every few week, janji is red color i will pour it in.
