"LUBRO MOLY" Diesel Purge in a can

nickel plate · Aug 8, 2011

I was at our local (small isolated town) NAPA store this weekend purchasing something entirely different when I asked who locally smogs diesel engines? Here in California I now for the first time in our state's history need to have my F-250 smogged. The fellow behind the counter recommended so-and-so and then said that their phone has been ringing off the hook from people asking if they carried a product called "LUBRO MOLY Diesel Purge, The strong medicine for sick diesels"? No fooling, that's what it says on the can. They just started carrying it a few weeks ago and at a quick glance I read on the 16.91 oz./500ml. pour can that it will "Clean engines-reduce the emission of CO2". How much I asked as nothing in that rural NAPA store has any prices on their stuff-six bucks and change-bought a can and off I went.
Get the can home and there is absolutey no mixing chart but it does say "Mix with fuel at each inspection as a preventative measure or apply directly in cases of problematic operation". WHAA?
Reading the can further, there is no website listed to follow up on and the product is made in Germany by LIQUI MOLY GMBH - D-89081 Ulm.
Contains: Naptha (petroleum) hydrodesulferized heavy. CAS# 27247-96-7 2-ethylhexyl nitrate, CAS#68784-56-5 benzene, Mono-C4-9-alkylderivatives.
My 7.3 litre diesel to my knowledge is not sick and I will not pour any of the can into the fuel tank until a find out more about this product-anyone know about or have used this product?
Didn't Germany invent the diesel or at least run with it more than other countries over the years?

Why not get your sticker. If it fails, then deal with it.

Come on folks! I know there are a lot of us that trade with NAPA. Diesel drivers-please ask about this product and post back.
BTW-Napa is going to have their annual filter sale, 60% off ALL filters starting on August 26 and going to September 9-if I heard my NAPA guy right. Only found out as I was in the process of purchasing a fuel filter for said diesel-mid forty bucks today, mid twenties a couple of weeks from now. Thanks NAPA guy! Verify this sale where you reside.

Here's a link to their web site. It's made mostly of naptha (cleaning solvent) that has the sulfur removed. I doubt it will make any difference in an emission test. Carbon Monoxide is very low in diesel exhaust to begin with. The main culprits are nitrogen dioxide, sulfur dioxide, etc.

Okay, that's all I needed to read!

When an engine is running most efficiently, it emits maximum CO2. If it emitted less CO2, it would have to emit more CO, which is the product of incomplete combustion. It looks like these snake oil salesmen are jumping on the greenie bandwagon that has decreed that emitting CO2 is evil. I guess we had better stop breathing so we don't emit any CO2.
