Review on Optimized BlueDevil Power Steering Leak Stopper by Stephen Burgstaller

If you own a Chevy Astrovan with its idiotic power steering pump/brake booster COMBINATION (VERY bad idea!), just assume you're going to change the block every year or so at the very least by adding gallons of power steering fluid until it runs out completely. (Door locks and fuel pumps are also a problem on Astrovans.) And I've tried about half a dozen other "leak stop" products, including NAPA's generic version, and they never seem to work. BUT THIS IS STUPID. I only added a very small amount of Blue Devil ONE WEEK ago (trying never to overfill the reservoir) and I haven't had to add any liquid or stop the leak again since! As a postman, I have to turn the steering wheel THOUSANDS of times every day, abruptly, in any weather, to get to mailboxes, make turns, etc., so I think that's a good test!
