I've just started running about B25 in my car and it does seem to run smoother. ..definately less smoke. I'm going to try and run B50 for a while. My understanding is you shouldn't run over B35 for any length of time because it will eat the natural rubber in fuel lines...and input here?

Just run whatever you want to run. When a hose starts weeping or leaking, replace it.

All you have to do is everyone once and awhile, take a look at them and make sure they are okay. I run mixed biodiesel blends and have had no problems.

I have used DP twice on the '87 300TD and once on the '84. I certainly agree with Brian about nothing to worry about. Why spend more money to fix something that isn't broken? So far, neither vehicle even burped after doing the purge correctly.

How does 'poor maintenance' create fouled pre-comb chambers and piston crowns covered with 1/8" of carbon? Its more likely a poorly driven car like grandma's diesel that never gets driven at more than 1900 rpms at 12 miles a clip and builds nothing but carbon on piston crowns, valves, pre-comb chambers and fouls injectors too.

Truth is that diesel purge does nothing that flat out high-rev driving on interstates doesnt do by itself, say on regular 1 hr commute twice each day at high rpms.

Bought my 240D on ebay 3 states away. Drove it like bat out of hell all the way home and could feel the engine improve. And them tried 2 cans of diesel purge to 'clean it out' for the helluvit just because everybody said it was the thing to do.... the process took 1 1/2 hrs of idling to burn up the DP from a coffee can. And it made very little difference at all. This was 3 yrs ago and i havent used DP since.

Then i went to Diesel Kleen w/cetane booster and *thats* when noticable improvement occurred.

Of course what i'm really wondering is if y'all Diesel Purge users arent scorching your bores with the stuff. And still caint figure out how the stuff could possibly be better than DieselKleen w/cetane booster that costs a whopping $1.25 to treat 20 gallons and *instantly* improves combustion that keeps engine innards clean.

Diesel purge AKA snake oil mostly used in noncompliance of manufactures directions pour a can in a tank of fuel and it will improve your mileage increase your performance and repair your sick engine back to health all in all a miracle product that will solve all your engines mechanical fuel system problems. Only cost you a hand full of dollars saving you untold fortunes in fuel bills repair costs and overall improve your driving pleasure. Then instead on just getting suckered out of a fist full of money You run it through your IP straight not mixed with a tank of gas. Against the even the snake oils instructions. In a car with no real maintenance records or knowledge since a fuel system solvent has been used on your car which is likely not often. You run a straight solvent through your IP has pumped 10 thousands of gallons of fuel and sat for millions of hours with fuel in it. Letting heavy impurities settle into a third of an inch of nasty hard crud a third of an inch on the bottom of the fuel chamber. And you decide you’re going to use a true good to be true product against even the con men’s instructions and loosen that crud to block precision holes that are so small that you really need a 10X microscope to see them in any effective way. These precision parts have no tolerance for even the tiniest blockages we are talking tolerances measured +or- 1 micron nor can the function if there is any erosion caused by causing thirty years of a sediment type of at least a volume of 7 cc to be rapidly loosened and run through your injection pump and your fuel injectors risking major expensive damage to your vehicle. Some people get lucky with this method and have a short lived improvement in there automobile. Many others are out a fist full of dollars. And I sell a lot of injection pumps who believed in a miracle engine additive. Would any of you like to but my engine additive that has been scientifically proved over and over to improve some engine short comings. I only want $50 per 16OZ bottle shipping is included of course you can buy it at you local auto parts stare for about $3.50 per bottle. But I figure if you pay good money for snake oil then use it in a way that can cause very expensive damage at the minimum to your IP and injectors and who knows how bad it is for the pre chamber ball when misused. $50 dollars for an additive that really does what it says is a great deal. Of course I have available W126 300SD gas caps used for $102.50 which is what some one just paid for one on eBay. Please PM me with your orders for either items. Due to the expected high sales volume of these items please allow 48 hours after receipt of paypal funds for your package to ship. If this was not sarcastic enough to make my point could I interest you in the purchase of the golden gate bridge with the rights to collect tolls expected pay of in one year!!
The Truth About snake oil
PS I have a few hundred thousand cans of slick 50 for sale I will give you a good deal

There have NEVER been natural rubber fuel lines in petrol or diesel engined vehicled.
They use Nitrile Rubber, which is affected by ULSD and Biodiesel.

As has been said before, preventative maintenance at oil / filter changes should include inspecting all hoses and fluid levels. Any cracked or weeping hoses should be replaced as a preventative measure.

i have driven a lot of diesels a lot of miles and the only thing i put in my fuel is injection cleaner, fungicide, and some marvel mystery oil from time to time. more often in the winter.

i honestly doubt the value of any of it but it makes me feel good to do something for the faithful diesels.

the main thing is clean fuel and clean filters.

I want to purge my 93 300D but I need to find out how you did it, What precautions you used and so forth..Was there a big difference in the overall performance of the car...Thanks

Darn marvel mystery oil is one of a few additives that are proven to work in studies conducted by the US government not the manufacturer. Now you let the cat out of the bag my $50 a bottle orders are going to tank, there goes my new Mercedes for Christmas. Oh well at least you can feel good about using it because it does do some good for your engine.
