BG 44K Fuel System Cleaner 4 Pack

I like to use this product about a week or two before I do the oil changes on my vehicles. It does clean the system well and my whole family can tell the difference in how their cars idle and run. The vehicles run more smooth, I like to use every 6 months.

Good stuff! Best on the market

It does seem to help with mileage and sluggish acceleration. Easy to use. Have used several times. May work better when used with 1/4 tank and driving out the treatment on a road trip allowing a sustained high RPM for a period of time.

Excelent product

Many mechanics use this. I use it for long trips to clean out your fuel system. I’m proved my gas mileage.

Of all the fuel system cleaner products I have tried, this is by far the one that make the most noticeable difference. To be fair, I have not try all of the fuel system cleaner out on the market (the not highly recommended ones). I figure is just a waste of my money so I only tried the most highly recommended ones. Have only tried Lucas, Chevron Techron, and Royal Purple Fuel system cleaner products. To be honest, I never really feel any big difference until I tried BG 44k. And this is on my 2 cars that are still less than 70k miles and have been using only Chevron gas since brand new of the car dealer lot. Even after that still can feel the difference, that says a lot. Is not 100% perfect though, in time I am sure somebody will come up something even better, but here is my pros and cons from my experience and opinion. Pros: Engine right smoother like brand new car Engine has more power Better acceleration Rough idle gone ( in my case I don't really feel it on my car, but after using it, I can still feel the difference of less vibration from idle). Cons: Only 1, gas mileage hasn't improve. Yea my 2 cars gas mileage has not improve 1 bit, but I also suspect it might be something else. Gas mileage had definitely gotten slightly worse since when they are brand new. I used this product even after new sets of tires, oil change (both engine & transmission), tune up (spark plugs, air filter, etc). Pretty much everything I can think of. I am not an unreasonable guy, just have to accept the fact that there will always be a certain thing about car you can never restore to brand new condition after they are used. Gas mileage lost is a problem has something to do with normal age, tear and wear of the car engine or mechanical parts. So that's why I am still giving this product a 5* simply because I have not run onto a product as good or better than this one yet.

Now Recommended by GM & Ford to help keep engines insides clean and running smoothly! Works quickly to keep fuel system injectors and internal combustion systems clean and efficient while maintaining and improving fuel economy. Previously we successfully had used with an 2007 GMC Yukon with good results was traded in with 287,000 miles ! GM suggests using in Fuel tank with every oil change we currently we are using with every other oil change with excellent results ! The BG products are very good and effective!!

This stuff is a tune up in a can, always good to add. I've used this stuff for years and it never disappoints. They have products for all of your needs, I don't get anything for saying good things about this but I trust the bg products on all of my vehicles.
