It's BG 44K. Best damn stuff on the planet, IMO. I use to use this in my other car about every 10-15K miles to clean everything out. Well, I didn't realize just how great it was until now. As you all know, the timing was off on my X for a long, long time. Figuring that I had carbon buildup as a result and that was the reason behind my excess engine noise and power loss (or so it seemed), I decided to try the BG in the Xterra to clean things up. All I can say is WOW!!! After 1/2 tank of gas I have a noticeable increase in power and reduced engine clatter. Seriously, my engine runs and sounds sweet...almost like the Nissan engine was yanked and someone dropped a BMW inline 6 in there. Well, maybe that's a bit exaggerated, but it's quite a bit smoother and better sounding. I also expect an increase in gas mileage, but I won't know for atleast a week after I fill up and drive normally on the next tank.

BG 44K is a professional grade fuel additive and not available just anywhere. I get it from my European Car specialist here in the Seattle area. Cost is about $22 per can, but well worth it. I highly recommend it's use on an occasional basis even if your truck seems to be running fine. My mechanic puts it in his Chevy truck every 5K miles. I'll try and get a phone number or something so you guys can track it down locally if interested. If anyone wants some and can't find it, I may be able to arrange something too.

Anyway, I'm totally sold on this stuff and am only posting my experiences. Maybe somebody else will think they have lifter noise or whatever and it's really just carbon buildup that can be removed by the BG 44K.

later!

Here's a link for an online retailer!

BG Products Website (http://www.bgprod.com/autofuel.html) Seems like they have a lot of overlap in their product line :)

Another link, seems you can get it at a Toyota parts counter (http://www.t4x4pickup.com/dgroup/messages/24662.html)

Now I don't have to find the info! :) After looking at the page, you're right. Would be confusing if I didn't know what I was looking for. Atleast i know the 44K is good and I've also used the Supercharge and it's good stuff too, although I wouldn't put it in every tank ($$$ go away fast!).

I called 2 Toyota dealers in south SF bay area: 1 has it, 1 doesn't.
Guess I'll have to leave work a bit early today...:D

Well, I lost 2+ MPG back in November. Like ChuckH, my timing was way off (probably from the factory) & I adjusted it about 4-5 weeks ago. Using this BG44K, I gained roughly 1 MPG. So, since I suddenly lost 2+ MPG in November, and this BG44K got me back ~1MPG, then it seems to me that I need a much more thorough cleaning to get back the other 1-1.5 MPG. Maybe I should press the dealer for a fuel injector cleaning on the warranty but I don't have proof of how bad my timing was off (20 instead of 13-17).
I think I 'll try one more treatment w/BG44K & take MPG data for 2-3 more full tanks & decide from there.

A dealer near where I work (Brown's Nissan, Sterling, VA) carries BG products, yours might too.

rosenthal nissan near me does as well. they even put it in as part of their 30K service. this time when i looked at the sheet i actually knew what it was from this post. hehehehe

BG 44K Online! (http://www.ec-securehost.com/RynoPerformanceProducts/Featured_Products.html)

I found this from Ryno Performance Products. Might save everyone some time!

How did you go about checking your timing??? I dont have access to a timing light. That concerns me a bit. Because I'm getting some lifter noise in the morning and a bit while driving.

There's a procedure in the How-to section here.

I picked up some BG44K at Brown's Nissan in Sterling, VA a month or so ago. Can't say I noticed anything after using it, but it's I figure it was worth it regardless. Get any crap out of there...

I'm at my witts end with this lifter noise on start up in the morning. I just had my oil changed at the dealer and now it does it every time it's cold! Any suggestions??? Does anyone else have this ailment? I only have 27k on mine. I have a factory oil filter (or at least that's what I think I have if the dealer changes the oil). It only lasts for a second or so. I hate the sound of metal on metal!!!!:mad:

My first oil change I used Moble 1 10-30. I still was getting a light clicking noise for about 3 seconds after I started the X. Now I'm running 5-30 and I can barely here it. Maybe try 5-30 or 5-40 weight oil? Just a thought...

I had the same startup clatter (very brief) with regular dinosaur 5w30 and the Nissan oil filter over the last 20,000 kms. Last week I switched to synthetic 5w30 (Mobil 1) and haven't heard a peep since. The motor is noticeably smoother now, I'd recommend going synth to everybody.

Has anyone tried the 0-30 M1 oil yet?

Not to flame, but is there really a problem?
I ask cuz I had a 79 Suzuki GS1000 and I was always checking the tappets with feeler guages and it was correctly spaced. But I could hear it, and it bugged me. There was never a performance issue.

I too have some noise on start (and even after start) on the Xterra. I have over 50K. I am just wondering if it is really a problem or not.

I wouldn't use 0W30 unless you live where it stays below 0 for long periods. It isn't even recommended by Nissan for any temp range. They call for 5W30 down to -20 F and below.

I seem to recall someone mentioning that there are 2 Nissan filters that fit the X, one has an anti-drainback valve and one doesn't. Whatever one I've been getting has it. A pint of oil spills out when I change the filter, even after the engine hasn't been run for over 12 hours. That pint of oil reaches the top of the engine almost instantly. No valve means the oil has to travel all the way from the pan.

Then again, I don't worry about a couple of seconds of tapping at startup anyway.

Howdy...I have a 1990 SE-V6 5-speed 4x4 Pathfinder with over 206,000 miles on the original engine and she's still going strong...but at start up first of the day I often get some clatter noise for a moment or two and when driving the first few miles there is an apparant valve tapping (no. 2 cylinder...when spark pug is disconnected...sound seems to be gone) that is somewhat annoying...and after a few miles it goes away to almost unnoticeable. Anytime the car sits for more than 10 minutes or so and then driven again the noise is back and then fades away again. The engine runs really well, does not smoke or burn excessive gas...I get over 300 miles to a tank! not bad I think.

Its helpful to see that I should have my timing checked ...other regular tune up stuff has already been done and I run Valvoline 10w-40 extra guard for older engines (is that a real deal or is Valvoline full of crap?) I tried adding a synthetic additive and it made no difference. I have used a fuel system cleaner and it did help performance when I first got the vehicle last winter...also added a K&N air filter. I think I will try the BG 44K products that I have seen listed here since it couldnt hurt right?!? I also saw where they have an Air Intake system cleaner too...has anyone tried that as well?

also adding a RAVIN free flow muffler and headers soon :)

If anyone else knows of any suggestions on reducing my engine/valve chatter..(hydraulic lifters) please let me know ok!

How many cans do i need? Do i just pour it in and drive? Sorry but i'm a newb, so help me out guys. Thanks ;)

One can of BG44K on a full tank of gas. Do it every 10,000 miles.

I have 2 other Suv's, 03' Grand Cherokee and 02' Pathfinder. It doesn't matter which car or type right?

Hey all,

About the BG Products. If the change in oil is helping. The HI L0W30 from BG is Mobile1 0W30 oil with MOA in it.

If you don't want to pay that much, go with your synthetic or traditional oil and add MOA to it. That might stop the tapping.

Also, if the BG44K doesn't stop the combustion clogging problem, have your local shop do a BG Fuel Induction Cleaning or EGR Cleaning on the vehicle. Those might take care of it too.

I just bought 2 cans of bg 44k but its not identical to the pics on the first post. Its part # is 208, i'm not sure if its the older version....is there a difference? I bought it on ebay, so i want to know if i got jipped or not. Thanks guys!

From what I know, 44K does not have an expiration date.

My sources say that one of BG's products did have an expiration date for a short time, however that has since changed.

I would think that if the can has not been opened then the chemicals inside are good. As for the look of the can, can images have changed over the years, however BG 44K, product #208 is a patented formula and should not have changed.

If you are still worried, go to www.bgfindashop.com and find a service department at a dealership or an independent store that has BG products in their inventory. Ask them if you can trade them in, or if you can get the number of the regional distributor for your area and see if they would trade it in.

reading this post is making me a little scared about getting my wife this 03 xterra,even it seems like a sweet ride,just reading this post is making think if i will be getting my self into any issues that i might like in the near future?

I have a 96 4.3 that has been idling rough for the last 5 yrs. I've had the fuel injectors cleaned and then replaced but it still idles rough. Reading through some of the posts I discovered that carbon can keep the EGR valve open. I took out the EGR and sure enough I could blow through the valve. After tapping, scraping and spraying with carb cleaner it finally sealed. After re-installing, the car ran much better for a few days then started to get worse. I pulled the valve again and it had a lot of carbon in it again and wasn't closing properly. I went and bought some Seafoam motor tuneup http://www.seafoamsales.com/motorTuneUpConsumer.htm which I read on some posts did a great job of getting rid of carbon build up. After all the smoke cleared I took it for a drive and it was more responsive and seemed to have better power. I also put some in the tank and after I empty the tank I'll install the gasket for the EGR that I made with a fine mesh screen from my wifes tea ball ( she'll never miss it!) sandwiched between 2 EGR gaskets with RTV sealent. This is supposed to keep the big chunks out of the EGR valve to keep it running smooth :p . I also ordered some Auto-RX to run through the engine. It's supposed to do a great job of cleaning out all the sludge and gunk that builds up in the engine along with freeing up stuck rings helping valve guides and engine seals. It sounds to good to be true but considering how much I've spent on Mechanics and unneccesary parts another $25 will be a bargain if half the claims for it are true. Check it out http://140.239.139.96/ARXforums/ . Will let you know how it turns out.

Can anyone tell me if this BG44K, would work to clean-up carbon build-up due to burning ethanol. I just bought an '08 flex-fuel Impala..Doesnt seem to pick up the way it should..It has 82,000 miles on it as it was a company car for the 1 yr and 11 months previous to my owning it, I assume that they had been burning E-85...I have spoken with a few mechanics I know and they are split on the effects of burning E-85...2 have said it would build up carbon on the intake and eventually need to be cleaned....2 said E-85 burns cleaner and that it should keep the engine cleaner then regular unleaded...I dont know who to believe but I do know that the car runs fine, it just should have more horse-power and pick-up off the gun....Ive used a generic injector cleaner in my 1st two fill-ups...not sure if it made much differance...so many questions I have here..mainly, do I likely have carbon build-up??? and will a generic injector cleaner help??? Or should I try BG44K??? Or maybe just follow dealership mechanics recommendations on what to use??? Appreciate any help or advise you can give me...
