I was told I need to change oil after using the PI. IS this true? I just changed my oil about 3 weeks ago (Asmoils ASM and K&N filter). Not in the mood to waste money on another oil change.
I do not see a reason to change the oil. Take the vehicle out on a 30 minute highway drive to boil off any chemical that managed to end up in the engine. Now a UOA may be skewed from a chemical reaction, if large amounts of the chemical ended up in the oil, but actual harm? I wouldn't worry about it.
Does Amsoil PI contain Polyether Amine? That is one of the ingredients in Red Line SI-1 and is also used in Techron. I am just curious to see if the different fuel system cleaners use similar chemistry.
