This is safe to put my 2017 Subaru sti?

Absolutely. Increasing the octane will only prevent engine damage that preignition causes. Octane is a measurement of the fuels ability to resist detonation. It is tested and given a AKI # Anti knock index. Using a higher octane then necessary will only burn up your cash faster. But using a lower octane when the engine needs higher can/will harm the engine.

Will this work in my 2015 focus st?

It woke up my corvette. The stuff really works

It left sediment in my clear gas can after one week. Has anyone else had this issue. Can I just shake it up and use it?

People usually put it in the tank and add proper amount of Fuel so can't really say, maybe next time I'll put it in a Clear glass jar and get back with you

Is it safe for an every day car? i’m just looking for something that will clean my fuel system and improves gas mileage. taurus sel 2011

If you follow the instructions you'll be fine. 2.6 ounces per 10 gallons, I believe, if you have emissions control devices on board, which you probably do since you don't have a race car. These guys dump the whole 32oz in their tanks and keep rollin'. I can understand your confusion. The video and bottle say two different things. If you are nervous, just go with Liqui Moly Fuel System Cleaner or Amsoil Performance Improver (Amsoil PI) every 4,000 miles or at your oil change interval. And use Amsoil Upper Cylinder Lubricant and CleanBoostMAXX on every fill-up.

Save $$$ on every fill up

My SUV doesn't like regular fuel. The manufacturer says premium isn't required—only recommended. It doesn't change how the vehicle drives, but the dashboard lights up like a game show. With the current price of premium fuel, I fill up with regular and add about a 5-ounce dose of this product. The SUV doesn't seem to notice the difference. The boost costs about $4, while the difference between regular and premium is around $13 per tank. That puts about $9 back in my pocket every fill-up, and my SUV doesn't seem to notice the difference. It works perfectly!
