BG 44K mixed reviews. What's the truth?
 

I've heard everything from, "It'll solve all your engine problems and find you a job" to, "It'll ruin your engine and impregnate your daughter."

The truth must be somewhere between those. Anyone know what it is?

Hmm..

I was under the impression that the BG 44K stuff was more for the gassers than the diesels.

I believe the recommended diesel equivalent would be

Around $9/can

BG 44k is indeed for gas motors.

BG 244 is the dump in your tank, injection/engine/fuel system cleaner. A few of my buddies with Duramaxes swear by this stuff. Bit expensive in that my local autoparts store sells it around 30 bucks a quart and recommend to get good results by pouring it in and using your car for stop and go driving with no long trips to let it soak.

BG 248 is the other stuff they offer. Much cheaper then 244.


With that said, Diesel Purge or getting quality fuel from a reputable truck station off the freeway are good ideas.

Start with a Lubro Molly Diesel Purge for $10 and then go from there if necessary.

The Material Data Sheets (MDS) (or is it Material Safety Data Sheet) are often on the internet. It might be interesting to pull up a few MDSes of Injector Cleaners and see if the Chemicals and % of Chemicals in them are the same.

You might find that it is the same-old-sh** in an expensive Can.

SOS in most cans, it's all solvent-based except the RedLine.

So what is the general consensus on doing a diesel purge?

I am not aware of the general opinions. The only thing I think is in about the middle of the purge shutting down and letting the stuff soak in the pump for a couple of hours or overnight might loosen up a lot more grunge.

Then run the remainder through. The injection pumps with rubber sealing rings in the delivery valves like the 603 I might avoid the soak though. For the 616 and 617 I see no harm doing this way.

Personally, I've not seen the point. Anything that a solvent will do in the pump however, would be by direct ingestion such as the often described diesel-purge method. Putting it in your tank dillutes it enough to be just fuel.

It is many people's opinion here that a tank (or so) of commercial bio-diesel has enough solvent to do the same thing, although the tank cleaning can cause downstream problems (don't ask how I know this) with filters.

I do feel that a regular application of my favorite detergent-based fuel conditioner can keep things flowing properly or clean the tank and fuel system, but regular use of the vehicle and good quality commercial fuel should not ever cause a fuel system problem that needs purging etc.

Snake oil.

Are you kidding? Please tell me you're kidding.

Not at all. Whatever you think you are getting out of diesel purge is just a half assed fix.

I actually agree, especially with injector cleaners in the fuel tank. They just cover up problems that need addressing. Straight diesel purge might clean the injector tips, but I don't think anyone can be sure of that. When I did a diesel purge, the pinging went away for a little bit, but came back in a month or two. I needed new injector tips. I don't think they make significant difference.

I do use iso-heet, however, to remove water from the tank, but that's it.

So what is the full assed fix
 

What would you recommend instead of diesel purge and what are your reasons for that choice? Do you believe diesel purge to be of no value and just a scam? Cheers Dan

BG 44K is an excellent product when used for an induction cleaning but I think anything dumped in the tank is pretty worthless. I still do it though.

As for diesel purge, my opinion is that 9 times out of 10 it's not needed, it all depends on what the issue may be and what substance may have somehow made it to an injector. If it solves the problem, $9 is a lot cheaper than a set of injectors if the problem just comes back it's not like nine bucks is that big of a deal. Bottom line I think the need for that product is the exception and not the rule.
