Anyone use BG Engine and/or Fuel Additives?

Sometimes I add a 1/4 tank of E85. Ethanol 85% will suck all the moisture out of your gas. I do it a couple times a year. The computer seems to handle it ok as I never get a code. I think fuel filter changes are more important than additives.

Too much ethanol is not good for cars not equipped to handle it - messes up fuel lines, pumps, etc.

REALLY bad for watercraft.

I've used MOA in engines for years as a mechanic and it seems to work in reducing friction. i also use it mixed with 5w30 synthetic motor oil for a lube for all my guns and the carbon seems to clean off easier(could be my imagination} and the actions do seem smoother.
The 44k never worked that well for me so i never pushed the product. Lucus fuel injection cleaner worked a little better and was cheaper. YMMV

I use seafoam for fuel and I use atf before an oil change as a sludge remover.

Adding stuff to fuel...in most cases can't hurt, and if used as instructed, helps. I add Lucas fuel injection cleaner to my fuel when I change the oil. I have three vehicles with V8s and use good filters and synthetic oil. With over 180K on the 2003, still in great shape.

Adding stuff to your motor oil...not a good idea. Oils have specific packages in them and thickening or thinning or adding a package that sets up an acid-base reaction in your engine...yeah, that won't be fun for you. Even mixing (as in quarts) is not a good idea. For older engines with sludge issues, adding a solvent (like BG Purge) can be a good thing and help. White Gas is cheaper and about the same thing. I used White Gas in my old Mopars at every oil change.

Using a quality oil filter and changing fuel filters is better long term than additives.

I like 44k, but I want to second not leaving it in the tank. Might be coincidence but I've had 2 mechanical fuel pump go after letting a car sit with it in lines. One was a pretty new pump. I've also read that Sea Foam is similar in effectiveness and 1/3 the cost if bought on special. I've read a couple factory maintenance recommendations that recommend adding Techron every 3000 miles. Kia was the most recent that I can remember.
