Home Made Injector Cleaner - PeachParts Mercedes-Benz Forum

I read a post by Old Navy or maybe Leathermang talking about the cleaning properties of Veggie oil. So I thought maybe I could improve on that idea. Today I bought a 16 oz bottle of Valvoline Synthetic Diesel Injector cleaner and added 16 oz of veggie oil. I followed the Diesel Purge instructions and ran it straight in. After a few seconds the engine stopped nailing and ran as smooth as glass. I have experienced this before, so I was not too excited. After the bottle was nearly gone I shut Hilda down and reconnected the fuel lines. With great trepidation I started her up. She now runs MUCH quieter and has MORE power. Not as quiet or as smooth as my cleaner blend, but I calculated the cost per gallon of my cleaner to be about $24.00 per gallon. So I will live with my results.

Time to start marketing!
But you'd have to get in the boat with Valvoline I guess...
maybe just to forum members?

I would guess B100 with that would be far better. WVO has no cleaning properties, Biodiesel does.

I have no local source for Bio-Diesel though........... maybe someday.

I hope I didn't post somewhere that VO or WVO has great cleaning properties, because they don't. When using those two straight they have some carbon deposit problems unless the injectors and injection timing are adjusted for VO. However the biodiesel fuel is a very high rated cleaning fuel, a 2% mix with dino diesel is all required to completely clean a fuel system with a little time. A 100% (B100) biodiesel can clean the average fuel system in just one tank, but on a 20 year old car could take a couple of tanks.

Shortly after buying my 240D I ran a tank of B100 through the system and man I think the car noise level dropped below the wife's '02 Jetta diesel. Man talk about smooth operation, just wish the stuff wasn't $3.35 a gallon. I have been running the car mostly on B2 49 cetane fuel since I bought the car and it seems a lot more peppy then other 240's I have driven.

Sorry ON, I read the post a few weeks ago, and can only remember it was someone whose opinion I value. I know it has good lubricating properties. But, I have also read that Bio Diesel is not good for the rubber in old diesel systems. Is it constant exposure to Bio Diesel that is bad, or could it be run in a cut down blend?

oldnavy · #7 11-18-2004, 10:09 AM

About the only thing that's on your or my MB that would be effected by B100 is the rubber return fuel hoses that are on the injectors or if you have the original rubber fuel hose on bottom of the fuel tank or the cigar hose made 20 years ago.

... and that means all of us- we're all experts. I've been paying very close attention to all the threads on Bio-D and WVO, and have ended up somewhat confused. Several have mentioned the way that VO cleans your system, but for some that seems to be a mixed blessing. It's been said that the Veggie will loosen all the Dino crud in the fuel system that has been there for... in my case 28 years, resulting in having to change your filters almost weekly. Others say that VO has no cleaning properties, but Bio-D does. Here in Canada, I can now buy brand new Canola oil at the grocery store for $1.00 / quart- practically the same price as we're paying for Diesel at the pumps right now. So for the sake of science, I could readily buy a shopping cart load of 4 qt. bottles and pour it into my tank if I wanted to, but if that's going to dislodge all kinds of crap into my fuel system, I'd be hesitant! By the way, I've put a little jar of said Canola outdoors and it's now down to 20 degrees F at night, and the oil is still as liquid as when warm with no clouding, so I could try this before putting Pearl away for the winter in a couple of weeks.

So- is this gonna dislodge layers of Dinosaur crap into my fuel lines or not?

I don't believe it will, but there is always the old try some and see what happens experiment.

I started using 20% WVO in September, prior to this only dino was used. Before I went to the WVO blend, I changed both fuel filters. The pre-filter was about 1 year old and had very little trapped in the screen. By October there was bigger chunks of black crud trapped in the screen, not alot, I am still running the same pre-filter. So, I would say the WVO must have loosened up crud from the tank/lines. I filter my WVO through t-shirts then a 1 micron bag, so I doubt I am adding any crud with the WVO. I also at the same time added 1 quart of Power Service injector cleaner (silver bottle) to each tank for 3 tanks in a row with the WVO. No proof positive the WVO or cleaner loosened up the crud.

A friend of my in MI who runs an electron microscope lab, told me that the carrier fluid in PS is B100 biodiesel and that amount would be equal to about 2% or 3% biodiesel mix in your tank. Equal to the 2% biodiesel I buy at the pump and it will take the crude right out of your tank with enough regular use. If you want to do a fast IP & injector cleaning, do the fuel line to the bottle direct and you won't believe the sudden difference in your fuel delivery system.

tomm9298 · #12 11-18-2004, 12:33 PM

What still confuses me to no end, is how well my engine runs while running cleaner direct from the bottle. O N, do you think it's the 2% bio mix or what. I mean it is a GREAT deal smoother and quieter. Just confused...

ON you posted about a month back that a gallon of veggie oil+Power Service would act like somewhat of a cleaning agent in a full tank o diesel. I did that and it smoothed out the nailing somewhat and it smells like fries.

tomm9298 · #14 11-18-2004, 06:48 PM

May I digress, why does it run sooooo much better on PS and VO?

Is it telling me my fuel is no good, I have marginal mechanical adjustments, or is it just FM? FM = F***ing Magic.

My friend has a 240 that broke a connecting rod.

He took the car to be repaired and was talked into a used 300 Tubo Diesel engine; with installation for $1600.

He got the car and it doesn't feel any more power than the old 240D engine. How should it feel with the 3L turbo? I have driven his car and it doesn't accelerate any where near my 190E. Is this normal?

Thanks in advance!
