I’ve discussed my oil guzzling 2009 Scion xB in a couple of threads here before and I just wanted to post an update.
Long story short I did two piston soaks about a year apart to my 2009 xB using Berryman’s B12 fuel system cleaner. I poured 1/4 bottle into each cylinder and loosely replaced the plugs to slow evaporation. After 24 hours I removed the plugs and cranked it over a few times, then repeated with a new bottle of Berryman’s.
When I bought the car in October 21 it went from full to the very bottom of the dipstick in 288 miles. The first piston soak improved that to a quart every 800-1000 miles. Now after the second soak I’m at 2100 miles and the oil level hasn’t dropped at all. I was hoping to see some improvement after the second soak but I wouldn’t have dreamed it would essentially eliminate the problem altogether.
Best $20 automotive repair ever!
