Here's a solution to the common oil-consumption issue on the Prius. This is made in Germany and is used on luxury vehicles like Audi, Volkswagen, BMW, and Mercedes. They too have consumption issues specially when they reach the higher mileage. I've personally used this on my Audi A5 and 2012 Prius when they started consuming more oil than usual and it never disappoints. Don't believe me read their reviews on Amazon. You'll thank me later. Cheers.
Photo's or links are not showing. Only tearing the engine down and cleaning or replacing rings will resolve the oil burning. At least for a while...
Pour & Pray products do have their value at times... But when an engine goes bad it needs to be fixed. This stuff might buy you some time, but it won't actually fix anything.
