Does Biomeer fuel additive (from Cavolution) really work to get better fuel economy?
They are basically fuel injector cleaners. AND YES they work to improve your MPG (if your injectors are clogged). But nobody uses those fuel additive for every tank (I often add about 1 or 2 tankful before the inspection). Forget all those SAVE GAS scams. This was on NBC morning TV show. The difference is as much as 38% (their claim). There are very simple rules to save gas: (1) drive slow - not too much past 55 (2) accelerate slowly (3) don't brake unnecessarily (4) use cruise control - whenever it is safe to do so. Don't coast - it is NOT safe and it does NOT save gas. The above really works. Using those simple rules I was able to drive from Boston to NYC (210.5 miles) on just 5.112 gallon (94 Civic). That's 41 MPG (94 Civic 187K miles). Actually I was speeding at 72 MPH so I could do even better at 55. WOW !! Assuming you are suffering from bad MPG. Get a tune up : (1) spark plugs (2) spark plug wires (3) coils, (4) distributors, (5) PCV, etc. (6) fuel injector (carb) cleaner - important Check your tire pressure. Get the ODB II scanned to see if it is reading and engine diag code. Sometime failing MAF sensor, O2 sensor or water temp sensor can kill your MPG. The water temp sensor is particularly cheap but a big MPG problem if it fails. The computer thinks that the engine has NEVER warmed and constantly run rich. And failed water temp sensor often does NOT create check engine light. As simple as that. Good Luck.
