2 stroke oil or mystery oil for 4 stroke engine

[skuttadawg]

I have heard of some using a sip of 2T oil for a 4T with bad rings .

Marvel Mystery has been around since the 20s or so . My auto repair instructor taught us about using it . Yes it will smoke if you put it in the gas tank but it burns off carbon in the heads and on the piston top . Put in the oil it lubes hydraulic lifters . It is not a " mechanic in a can " but it can fix some issues of neglect .

SeaFoam is a great product that actually works ! I put in a sip here and there to keep the fuel system clean . I have only used it that way and to clean dirty EFI injectors , but I have read where many use it instead of Stabil when winter storing a scooter . Walmart sells it cheaper than auto part stores do .
