BG 245 Premium Diesel Fuel System Cleaner

Keeps my motor running smoothly.

I used this directly after an oil change and an injector seal repair (had a leaky injector seal). there was an almost immediate difference in how the engine smoothed out, and engine noise became quieter. I also noticed a small gain in throttle response.The BG245 probably removed the carbon gunk that I saw on the injector I removed. I cleaned that one in ultrasonic, so I suppose the other 5 had gunk as well that the BG245 cleaned. Hopefully it cleaned out the fuel system as well , as it claims. I will be using a quart in the tank after every oil change as a preventative measure to keep the fueling system clean.

Love this stuff. I own a bunch of old diesels as a they always seem to run great with after using bg245.

I have been using this additive for years and it keeps my fuel system components clean and working in top condition.

Worked as implied not a real big difference in mileage

Highly recommended by the Dodge dealer. They charge more for it. I wish it had directions on the bottle. Lots of warnings about exposure but nothing about how much to add or ratio. Seems to make a good difference on performance and slight difference on mpg. Not sure how often to add. Maybe as often as the oil change. Don’t be confused, this is a fuel/diesel treatment.

I only use a quart of this twice a year. It’s not the only product I use in my fuel, but I believe it to be the best.

Got 64k on my 6.7 powerstroke. I have always run XL opti-line in my girl for lubricity, well we all know extra lube burns a little fat. I noticed some white smoke when busting the old hauler off. First sign of dirty injector tips on the 6.7 powerstroke's piezo injectors. How do I know? We have a few hundred of them in oil field of Alaska where I worked. Best cold weather or anywhere light duty diesel engine made since ford built there on diesel engine, the 6.7.Anyway the bg 245 works after about half a tank run through my truck.Works better if you add to a full tank so it prolongs the treatment. It also works better if you use that tank for short trips so it can soak in the areas that are carboned up. I have used everything this works the quickest. Worth every penny got my mileage back up to 20 plus I was down to around 18.
