Looking forward to this DIY as I have just cleared 133k miles, I'm kinda worried that I'm going to scare the neighbors with the smoke plume that I am likely to cause. All good though, noticed diminishing MPG's so this will hopefully address that.

I will have to try this. I'm getting 30mpg Highway but no matter what I do I can only manage like 16 city. Plus with 172xxx I'm sure it needs it.

Will running SeaFoam ruin the O2 sensors? I'm due for smog and do not want to ruin anything.

i'd like to add: CHANGE YOUR OIL AFTERWARDS.

How long can I wait to change my oil? I put sea foam in last night and have driven roughly 6 miles since I’ve done it.
