Power Service ,1%-8% ethylbenzene
2% to 4% xylene
80-90% hydrocarbons (diesel)

Lubro Moly
Diesel Purge ,1% trim ethyl benzene
15% 2 ethyl hexyl nitrate
8% petroleum distilants
1% ?
73 % hydrocarbons (diesel)

MSDS or Material Safety Data Sheet
gives a formula for Lubro Moly except for 1%

Power Service is pretty tight on info data about their product, you cant get a MSDS unless you request it from them , and still I doubt if theyll reply.

Im just curious about what Im cleaning my injectors with.

Hydrocarbons can be gases (e.g. methane and propane), liquids (e.g. hexane and benzene), waxes or low melting solids (e.g. paraffin wax and naphthalene) or polymers (e.g. polyethylene, polypropylene and polystyrene).

Unsaturated hydrocarbons have one or more double or triple bonds between carbon atoms. Those with one double bond are called alkenes, with the formula CnH2n (assuming non-cyclic structures). Those containing triple bonds are called alkynes, with general formula CnH2n-2.
Cycloalkanes are hydrocarbons containing one or more carbon rings to which hydrogen atoms are attached. The general formula for a saturated hydrocarbon containing one ring is CnH2n.



The average chemical formula for common diesel fuel is C12H23, ranging approximately from C10H20 to C15H28.


So the answer is maybe. 80-90% Hydrocarbons could be hexane or benzene

... which is why adding it to your fuel tank is pretty much useless, and it only tends to scavenge crud from your fuel system when added directly to the inlet of the engine.

Solvent-based fuel treatments in the tank don't have a chance.

Diesel purge isn't an additive. You unhook the IP from the tank and run it right off the bottle.

Let me clarify where I was coming from. All diesel is a hydrocarbon, not all hydrocarbons are diesel.

To answer your question "Are Diesel purges ,70-90% diesel to start with ? YES!! - simply high cetane diesel boosted with 2-EHN and a splash of a solvent e.g. xylene!

2-Ethyhexyl nitrate (2-EHN) is added at 0.05% to 0.4% to most if not all diesel formulations in order to increase the cetane number. 15% 2-EHN,as quoted in Lubro Moly (and these other snake oils though they won’t admit it!) is a massive overdose and your engine is quieter and smoother entirely as a result of the inordinately high cetane level. In short you are being cheated, duped and ripped off!

The performance of an injector is dependent solely on the condition of the nozzle needle seating provided that it has been set up correctly in the first place. No amount of cleaning will repair a damaged seat. Suspect injectors should be removed and checked by a qualified person and the nozzle replaced if defective.

Don’t waste your money on these useless snake oils. Rather invest in a 2 micron filter and water separator. Injectors require no other servicing throughout their lives though many an unscrupulous shop (or person!) will offer to “rebuild” them for you even if the nozzles are serviceable!

He asked about the content of "diesel additive" products. As compu also pointed out, LM Diesel Purge is not a "diesel additive". What did I miss?

Lubro Moly can be added to the fuel as an additive ,the can reads off this info.

Anyone know about Sea foam engine treatment? I've used it as a substitute for diesel purge, pretty much does the same thing but you can use it jsut as well in gas vehicles.

Lubro Moly seems to think that Diesel Purge is an additive.

Ha! Ok well then, fair enough! I've never heard of anyone pouring it into their fuel tank, since it's far more effective to run it straight. But what do I know.
