so i have been noticing that my car dirtys up oil very quickly. i also have a pretty bad lifter tick. someone on here told me that marvel's mystery oil does the trick. you put it in, run for 5 minutes then change your oil. the turtle wax site, says to put it in with your oil everytime you change your oil? also i was looking at valvoline pyroil engine flush. the directions for that say Add to crankcase and remove after 5 minutes. that seems pretty simple, and the overview says it helps sticky lifters. an then there is amsoil engine flush. this stuff seems good but the directions threw me off: To quickly clean residual sludge and engine deposits, AMSOIL Engine Flush is recommended: Change the oil filter and add the flush (about 10% of the oil capacity). Do not overfill the crankcase. Idle the engine 15 to 20 minutes, then immediately drain the old oil and flush. change the oil filter then put it in, then run, then drain oil? seems odd to me.... so which of the three would you use? i dont want to mess anything up. my usual oil combo is motocraft 10w-30 with some engine restore. sometimes i use some stop leak stuff becasue i have some leaks. if you tell me to go with marvel's how much do i use? i asked my friend whose dad owns a bodyshop what to do and he said that he never heard of that stuff, but he has heard before that there is something out there that turns your oil acidic and cleans everything up. is that what this stuff is doing? on a side note, i got magnetic pan plugs, and they have really thin washers in them. should i just keep using them or use the washers on the stock plugs? can i go to advance and get stock washers to use on my magnetic plugs? thanks for all the help guys.
