Who has used BG44K? What are your thoughts? (Or any other BG products)

[customa4]

I put the BG44K in with about 1/4 tank and then run it as close to empty and then fill up. The added smoothness just gives you the urge to go WOT even if it wasn't your intention. It says it treats up to 20 gallons with one can so it wouldn't be a problem to fill the tank.

When you ran it close to empty you basically used all the 44k in the 1/4 tank right? I'm not sure if I should run it with 18 gallons of gas or very concentrated with like 5 gallons of gas. Not sure which would give better results in cleaning the engine.

Also, are you going to do an oil change?

I ran none with a quarter tank. Then topped it off to a half tank. Then ran that down to E

I just want to bring this back. Since running bg44k through my 3.0, my so called failed cat is no longer failed. I haven't seen my check engine light in over 1000 miles as of now. We'll see how long that lasts though

How often did you add this to your tank? Has it been only once for those 1000 miles, or every 'x' amount of miles? Seems like something I'd like to pick up...




Also, While on the subject of BG products, I am debating between two different methods of oil treatment: The BG MOA leave-in additive, or the Liqui Moly 10-minute engine flush..? I haven't heard anything at all (Good or bad) about the MOA, and mixed reviews from LM, by people that have never used it.. All of the negative things I've heard about the Liqui Moly seem to be hypothetical.. i.e. it "could" be bad for seals or it "might" dislodge a tiny piece of sludge that could cause a clog somewhere else... But no one has actually said any of those things happened to their own engine...

Either way, thanks to this thread, I'll be picking up some BG fuel treatment.

This seems to be the best deal I've seen. I'd be more curious about the BG 109 engine cleaner to restore performance and compression. Supposably it gets in and cleans up any engine gunk and cleans the pistion rings and can bring your compression up. I'd be very curious to see some before and after compression #'s. Someone said the 109 is just a stronger formula of the BG Quick Clean which is used to clean sludge up I guess. Here is a link to the product page. Says in their testing a car got a 35 psi bump in compression.

I have a can of it here and I'm waiting to log a couple thousand more miles before using it. Going to try and clean off some of the varnish from the engine that has built up over the past 11 years and 180k+ miles.

I only used it once. I had received a free can from a Buick dealership (dont ask) and I ran it with about a quarter tank in the car for about 30 miles, then I topped off to a half of tank and ran that almost dry. According to my dash, my fuel economy has stablized around 25.5 mpg each day too and from work now. Usually it would fluctuate between 23 and 27, mostly around 23. The car certainly has been idling better since using this as well.

Recently purchased my 2002 1.8t (b6) A4. Dipstick broke and got a new one all the while enough oil had come out of the dipstick nozzle for the oil light to come on. So with 120k on the clock Im going to purchase BG-44k tomorrow which is a fuel cleaner.

Great Im sure my fuel system is really filthy because the Audi was used as a commuter car for 20-40k Miles ( I know that is a large range) .


But IS there a lot of Engine build up with this much mileage? is it more common the turbo models?


Under the assumption there is I want to get an engine cleaner and stick with BG products because I have heard sea foam is more dangerous/harmful on these motors because of the turbo

[poncho1015]

what product should I use and has anyone done this before with success

[imnuts]

BG 44K is for the fuel system and BG EPR/109 is for the oil/crankcase. If you have the 1.8T, it is more likely to get crap built up in the engine. I haven't seen any reports of people using the EPR yet, but I have a can waiting to be used in another ~1k miles when I change my oil again.

[Furly]

i used this stuff few months back. its a good product. but if you use quality fuel you wont need to clean your system really.
i did mine because i did not know how the previous owner took care of the car.

i dumped the whole can into an empty tank of gas and filled up with 91 octane from shell. i feel like the BEST way/time to use this stuff is before a road trip.
i went on a 200 mile trip to visit family and really let that stuff work its magic.
the more you can let it flow thru the fuel system the better its going to work. putting it in your car only to drive it to work or in stop and go city driving wont clean as well as a long nice drive.

you wont notice a difference until you are completely thru with the whole tank of gas and you refill again. i think after the second tank i noticed a small increase in mpg and fuel delivery.
this stuff claims to be 100% more concentrated than techron, so go and dump a can in your tank if you haven't cleaned your fuel system in a while.

best place to get it, is probably amazon.

[n7plus1]

wtf is BG?

i exclusively use amsoil engine flush and seafoam.

[customa4]

It's a product that's used at most dealers for many different makes of cars across the country. Good stuff.

On my 2nd tank since the fill and I'm calling it a win.

Acceleration is certainly smoother than before, car feels good regardless of missing a few pounds of boost.

My Injectors have 130k on em so regardless of my strict adherence to best quality / highest octane gas available there still had to be deposits that needed to be cleaned out. Good stuff.

[xhackerekx]

I think seafoam made exactly same job.

[n7plus1]

highest octane gas available there still had to be deposits that needed to be cleaned out. Good stuff.

i claim the same results with seafoam. 8oz to 8 gallons of 93.

I usually only ever fill up at my local Sam's Club.

1. Mostly b/c i pay for a membership and its always cheaper there.
2. Helps make up for paying for a membership
3. Never have issues with their gasoline
4. They carry 87 and 93 and thats it.
5. Local.
6. Never heard any issues with their gas.

[customa4]

Try a can of BG44K and see if you feel the same. I personally thought BG44K did a better job and I've used both. The Seafoam did have positive effects on the car but I felt BG did a better job.

[customa4]

Just got 2 cans. How are you guys using it? Fill up tank all the way, add 44K and drive normal? Have 1/4 of gas in tank & fill 44K and drive normal? Or WOT the whole time the 44K is in the tank??

What did ya think?

[customa4]

BG 44K is for the fuel system and BG EPR/109 is for the oil/crankcase. If you have the 1.8T, it is more likely to get crap built up in the engine. I haven't seen any reports of people using the EPR yet, but I have a can waiting to be used in another ~1k miles when I change my oil again.

I used a can of the EPR and it did slightly bring up the compression numbers on my motor. The car actually ran quite a bit smoother as well.

[WB650]

Are you guys changing oil after using this? Read quite a few things on the net about changing oil after, just changed my oil this past weekend so I dont wanna risk it. Other than that, I'm gonna dump it in when I'm at a qtr tank then fill up the gas and take a long drive.

[customa4]

I've never changed my oil after using BG44K. I've probably done it about 6 or 7 time between different cars, never had a problem.

BG44K? No, you don't have the change the oil. The EPR/109 and Quick Clean, yes, you'll want to change the oil if you use either of them as they are meant to clean up and break loose sludge and other buildup, so you want to get it flushed out and put new oil in.

These things scare me. Sometimes there is gunk that is keeping a seal from leaking and when you clean it up, it leaks! I will continue to stick to high detergent oil like T6 for my cleaning purposes.

There has been no down side to any of the BG products that I've used. Each and every one has worked great and I haven't had any problems. I haven't read anything negative in the few times that I've searched the products online besides the people that haven't used it. I went to a local VW recently to pick up the BG EPR, which they didn't have in stock. The guy at the parts counter pulled out a big gallon jug of a different engine flush from BG and said that's what they use when customers come in with oil sludge problems. He said they run it through the system and then flush the oil I believe a total of three times.

If VW and Audi along with many other car dealers are using BG products on a daily I would think it's safe to say it's not a harmful product.

[SJorge3442]

The EPR is an engine flush and restores compression so it will need to be drained. The BG MOA/109 is meant to be run in the crankcase for the life of the oil. It is supposed to prevent oil sludge.

Im not saying its unsafe, im just worried about high sludge engines and flushing them. its the whole thing when someone switches to synthetic oil after running conventional for the first 140K miles. The cleaning properties of the oils expose leaks that were orignally covered by years of gunk. Either way, my engine is spotless (at least the heads are) so Im not worried about it, and I will be doing a EPR flush soon. Maybe with my next oil change

[customa4]

LOL! I used it, it's good stuff. I did bring my compression numbers up a slight bit as well. My car was also running pretty smooth after I was done.

BG EPR is the same as BG 109. PN 109 was the original name for it, before they came up with Engine Performance Restore. BG MOA is an additive that is left in and used after the oil is changed. BG 109/EPR & Quick Clean are flushes meant to clean crap out, are used before the oil change, and should have the oil changed when used (follow the directions).

[customa4]

Ahhhhh, yes, you're right. I meant BG 110/MOA.

Edited my post.

Have anyone used Liqui Moly fuel or oil cleaner? What are your thoughts and results?

[f0reignfeatures]

I know this is an older thread but I'd like to add my experience here. After reading through this thread doing some research I decided to give BG44k a try for my 3.0.

It's been a several hundred miles (2 fill-ups or so) since I put it in the tank and although my MPG's haven't really improved, the car idles waaaaay smoother.

Once the car is warmed up it's amazing how smooth it idles. The motor is silent and I can barely feel it, whereas before it always felt kind of choppy. Performance wise I'd like to say it's running better but that could just be wishful thinking.

The stuff is somewhat pricey, but I am very satisfied with the smoother idle.

Could that have anything to do with the car being 15 years old? The motor mounts are probably bad by now.

Motor mounts could definitely use a replacement but I'm not sure you read what I posted.

The idle noise disappeared a few hundred miles after running the BG44k.
If it were the mounts the noise and feel would've persisted.

I'm always skeptical of additives but this made a noticeable improvement, hence the reason for my post.

I keep finding my dad buying the junk snake oil from autoparts store when they have them on sale at the counter. I CANNOT get him to use BG. I need to directly order a can and have it delivered for him, otherwise he'll continue using the GumOut stuff. I have a can of the BGR EPR sitting on my shelf, waiting for my next oil change (weekend of the 5th). I'll be positing up some stuff about that when I run it. Gonna do some before and after videos to see if we can get a difference in engine smoothness.

It sounds like you've had about the same experience as me. Nothing but positive things to say about BG44K on my end.

I actually just ran some BG EPR through the Camry 2 weeks ago when I did the oil change. The car seems to run quite a bit smoother. I can say I was very impressed with it when I used it in the Audi. I even did compression numbers before and after and it brought the numbers up quite a bit on every cylinder. I'd have to dig to find them but I remember it being a nice bump.

Maybe if I am feeling ballsy I will pull some compression numbers from my front cylinders. Hell, I need to get some pre-season compression numbers on my jet skis before the hit the water, so it would sorta make sense. In regards to percent change, how much did you see it change?

I'm not exactly sure what the change in percentage was. Maybe like 140 psi to 150 psi. I know I recorded it in the notes on my phone but apparently that note has escaped my phone. I'll see if maybe I have the numbers on my laptop.
Found them:
Cyl 1: 130 -> 140
Cyl 2: 120 -> 135
Cyl 3: 135 -> 150
Cyl 4: 150 -> 165

(not the best compression numbers, I know, but still got better after EPR)

This was after BG EPR, oil change and BG MOA. Roughly 10-15 psi increase on every cylinder.

10% average increase per cylinder according to my math. That's some solid increase right there.
