I like following Project Farm on YouTube. He does a lot of good work on interesting topics. I recently shared his one on diesel fuel anti-gel treatments somewhere on here. I thought this one was share-worthy too. I hope this carries over to gasoline engines (so long as you use good oil; I'm running AMSOIL products in my Civic and Canyon) as my Civic is approaching 1 year from the oil change as It just hasn't been driven. Enjoy!
