Diesel clean has such a peculiar smell, I know I have came across the chemical that gives it that smell but I can't remember what it is. Any of you ladies or gentlemen know? Touline? Xzylene?

I'm unemployed till September and I get a lot of driving between our place and my parents place and I hate to cheap out on diesel clean but looks like I may have to.

Yea but it's not nessasary every tank. Do you think its nessasary every time you fill up?
Liquid diesel purge from Molley is the best anyways.
Millions of tdi owners never put a drop of any cleaner in the tank and plenty get that car up to the 300k milestone.
Do what you want but it's not nessasary for your brief unemployment period.
As to your question I used it once and it smelled a bit more like Ballistol to me.

For $10 a straight LiquiMoli diesel purge cleans them and the pump. Never used the product you speak of or anything else. Is there a symptom that leads you to believe it's necessary?

Playing mad scientist with carcinogenic solvents and such is likely to do more harm than good- for both the car and the car owner. I wouldn't stress over it, pump fuel is fine. Very few owners use fuel additives with any regularity.

Diesel fuel has salts that precipitate out and cause deposits on injectors. This will eventually effect injectors and cause a loss of power and efficiency.

Additives are 100% beneficial and also can improve all properties of fuel (Cetane, Lubricity, deposit control/detergency, lower soot production, etc) when added at every tank. Additive effect is highly dependent on fuel quality, so if you’re in a state that has marginal fuel quality made to the federal standard an effective additive will have a huge improvement on how your engine runs.

these salts get abliterated with high heat and compression. you know... those engines we all have that go 300 to 500k with out even putting any of that snake oil in it... enjoy your salts... no one else is... wait.. i mean.. oh whatever

There's really only going to be appreciable salts in poorly made biodiesel with excess catalyst. Shouldn't be a problem in pump fuel. Aftermarket fuel additives are mostly useful in extreme cold weather.

Some people are just more susceptible to slick advertising than others. I remember when you couldn't walk into auto parts stores without being bombarded with the Slick 50 displays with videos playing and all, lol. Power Service is one of the more reputable aftermarket fuel treatments, so I won't harp too much on it, but Mongler is correct- most people make do without the placebos and still rack up impressive numbers on the odometer.

As I've always said.... a mechanical problem can not be solved with a chemical solution.
There are only 2 reasons to add anything but fuel to the tank.
1: I'd your not adding fuel from a pump. Aka home brew or sketchy put of a can unknown.
2: cold temps and fuel issues. Gelling or bacterial issues

The only decent cleaner for nozzles is the ones you run in a closed loop.

Past this... add whatever you want by subtracting wallet value or adding fuel cost. Mpg is usually mitigated by repairs and cost of product.

Salts... more power... better mpg... all of these are snake oil salesmen tactics absorbed by sheeple at pepboys and autozone

Also this is the first time in my life I ever heard of anyone having salts built up on nozzles from pump fuel.
I've seen it actually plenty on bio and oil and veg burners
It's like a crystall structure of soot. Almost like the "sugar" effect of non purged tig welded stainless.

I had bad fuel before, ad the smoking only went away with diese kleen. Usually I fill up on the rez to save a few bucks. Not usually bad, but diesel kleen works even when putting old diesel in the tractor.

Also, free world, I want cheap diesel kleen.

Like I said. When fuel supply is not up to snuff.
I've used it plenty on old fuel we have stored and on out door equipment.

See if there is an MSDS for it online - if there is it should show what gives it it's characteristic smell.

10 or 12 yrs ago after I bgt my first TDI there were many,many threads on blown HPFPs. It was caused by poor fuel quality ,bad lubricity low cetane. You don't see these threads much anymore. Maybe new pumps,better fuel? I don't know but I've used diesel clean for 15yrs now, no problems,I have no proof it 's diesel kleen,but it's cheap and I'll keep using it.

how many miles?
15 to 18 bucks a bottle
im assuming you did 250K in 15 years... some what normal commuting miles at 45 miles per gallon over 14 gallons per tank basically = 400 tanks or almost $7 grand spent for what? seems with that kind of money you could do better with replacing the fuel and injection system 3 times over or every 5 years... but that's the gamble right... like you said... will a product designed to do only one thing... make a company money by making you sure you need it.
I remember those posts... it still happens. low surfer fuel switch was doing to crazy things according to the people who drew coincidence with the failure they had to the fuel they used. hard to say.
if you feel its ok to spend the value of your car over its life on a wish and a prayer then go for it. but one hting is for sure... the car was NOT designed to have fuel aditives like this... and the fuel is approved for the car at the pump... usually.

I think it makes more sense for the OP to just avoid fueling up wherever he was getting the crappy fuel.

Diesel additive is cheapest in bulk. I buy the 5 gallon drum. When you add it in at the proper dose of 400:1 it costs an extra $0.11 cents per gallon of fuel.

It literally pays for itself by increasing fuel economy, keeping your intake manifold free of soot and ensuring the injectors remain free of deposits. The protective properties are a bonus.

some people are hard fast obsessed with adding snake oils to things to get more ouf of them from seat dyno resustls.
FIY i have made my own seafoam and its NOT the same... I used mine for my 10 gallon ultrasonic cleaner parts washer project. seafoam and my home brew stuff are 2 completely different box of frogs. your home brew will separate on its own and it will vaporize when put in the ultrasonic cleaner and it gets HOT from the added energy. Proper Seafoam did NOT do any of those things. i ended up going with PCS 1000 from tractor supply.
bottom line.. whatever OP is doing, its bad news.
I just followed what i froun on redit and google to make it. it does remove varnish but its NOT seafoam... hence why there is a patent on it...

Nah. Been making diy seafoam for years, a better version of it. This diesel kleen is a pet project
Well, as long as it's a pet project I think you should make a real witches brew of it for fun. A dash of this and sprinkle of that, etc. Go for variety, the more stuff the better. You could even make little labels and call it PowerJuice 10,000 or something.
