Only if your injectors are dirty & causing an uneven spray pattern AND only if STP Gas Treatment actually cleans them!
But my experience is the product is worthless and belongs in the "snake oil" category.
Want to increase your mileage?
Keep the engine tuned Watch your tire pressure & make sure the pressure stays on the high side Replace any worn suspension parts and have a quality 4 wheel alignment done Run synthetic 5W-20 oil Drive more conservative (might be impossible in a Vanagon) Buy gas from a station that sells alcohol free gas - this will have the greatest impact Remove any accessories from the outside that may be causing drag like extra wide mirrors, etc Remove unnecessary weight Fix any loose trim
