16 fl. oz. Briggs & Stratton® Advanced Formula Fuel Treatment & Stabilizer (100119WEB) is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from product full of sediment Over the years, I have been very happy with the "Fresh Start" product, so I was happy to see a "new and improved" version until I received it. It was full of black sediment stuck to the inside of the bottle and pouring sediment into my gas tank didn't seem like a pleasant idea. I was told by a dealer that there were some "early batches" with a known problem. So, I tried to call customer service and just got the run around and then when I asked to speak with a supervisor, the customer service rep hung up on me. I would be very wary of using this product.

Reading over the Q&A's from each of the different size bottles you have, there is two similar ones. "What is the shelf life once the bottle is opened"? In one answer it's 3 years and the other it states there is "No expiration".

Asked by: MScotty
Thanks for letting us know about the mix up. The correct answer is: Shelf life is 2 years unopened, opened product should be OK as well for that long if its kept sealed.

Can this fuel treatment be used along with a 2 cycle oil that already contains a fuel stabilizer? Not sure if that stabilizer will prevent any ethanol issues.

Asked by: MScotty
If you are already using a stabilizer in the 2 cycle mix you do not need to use an additional stabilizer
