Thanks for the link. I may look into that later. Right now I'm letting the MMO soak in. I figure for the few bucks the bottle cost it can't hurt to try. I'm wating for new heat shields in the mail so the car would've been down anyway.

That all makes sense. I suppose I'll just have to wait and see what results I get from this. I poured it in last night. I ended up using a long funnel that went into the inector hold. Did about 1/4 cup per cylinder.

Since the MMO drains past the pistons into the oil, I'm guessing it would be a good idea to change the oil out after this, no? My local Wal Mart has the 15W-40 Mobil Delvac on sale so I'm good with that. haha

I put 1/2 qt of MMO in my crank case with every oil change, on a 5qt engine.

Nothing to lose and little if anything to gain. The dilution of the oil by the draining down of the mmo is not a real issue to me anyways.

Leaving it in the base oil will aid in further internal cleaning of the engine. Personally I would not change the oil for awhile. Let then mmo work. As long as less than one quart of mmo was used.

It is getting colder this time of year so a little resultant thinning of the base oil is of not much concern to me. Others may probably feel otherwise has to be a given.

I see adding marine 2 stroke oil to the fuel mentioned here. How much to a full tank roughly. Is USLD everywhere? The pump I use says not for 2007 and newer diesels, does this mean it is not USLD?

I thought that USLD fuel was the norm across the nation.

I use 2 cycle oil to my fuel, the stuff they sell in Calif looks like water, not like the fuel they use to sell when I was a kid. that stuff had lubricity to it and was oily. I might be a little heavy on my ratio, I add one oz per gallon, I have read where some add 1/2 oz.

That's exactly what I've been running as well. With the ULSD's lack of lubricity, a little oil can't hurt and can definitely help.

I spent some time looking for a place I could buy a sulfur additive to make it like it used to be, but no luck.

According to a diesel lubricant study by "Spicer", biodiesel added to ULSD to form a 2% mix was the best lubricant!

I'm currently running B100 (100%) biodiesel from a commercial ASTM biodiesel station near me. The 240D loves it. Running really smooth (well, as smooth as a 616 can run... )

We have one station here in Santa Cruz that sells 5% Bio-Diesel, and another one that I think sells 100% Bio-D. may be others. but I don`t chase around for it.

I first heard about the 2 cycle oil on a Dodge Diesel forum, think the guy was Moparman. claimed to increase his milage some.

Hi Charlie,

One easy way to see how nicely the 240D runs on B100 is to pick up a few gallons in a portable container, and then set up your car for a 'diesel purge', but using the B100. I think you will be surprised at both how high the solvent-value is on B100 (as you see deposits being removed from the fuel pump and injectors) and how nicely the engine runs on it. It does have a little less power (due to B100 having less energy than #2 Diesel), but it cleans the fuel system and injectors nicely.

I can't prove it, but on my Diesel Tahoe, I believe the B100 took care of my blow-by. I had significant blow-by when I first bought it. After running it on B100 for months, I happened to check the blow-by, and it was GONE. The only thing I can think of is that the high solvent value of the B100 eventually broke down the varnish/carbon on the cylinder walls. All I can tell you is that I don't have it anymore. I did change a few other things, like opening up the intake and the exhaust (i.e. larger intake, larger exhaust), but I didn't really change anything else.

BTW, I suggest using the B100 out of a bottle (i.e. diesel-purge style), because running a full fuel tank of B100 in a vehicle that has never run it will cause all kinds of deposits to come off the inner surfaces of the fuel tank, fuel lines, etc, and totally gum up your fuel filters, stalling your car.

Therefore, I usually start with a low mix and ramp up to B100 tank by tank. Biodiesel can be mixed with petroleum diesel in any ratio. I usually do B20, then B50, then B75, then B100 over several tanks. I monitor fuel filters very closely and usually swap them out a couple of times before I get to B100.

Sincerely,

Packman

My local service has 20% Bio diesel and that is what I run if I need to fuel up near home. I have been using it for a year on my VW IDI turbo diesel.

My experience is that cylinder soaked with MMO would not work. I took out the pistons of the SDL and found 3 of them with stuck rings. Soaking them in MMO did not loosen them. It was so bad that I had to pry out the rings. I needed to scrape all the carbon out using a knife even after soaking the pistons in solvent, solvent similar to Simple Green. This is my experience. Others' may differ.

What you describe sounds like ring polymerization from injecting insufficiently heated WVO/SVO.

Totally stuck rings require disassembly to correct. However, partially sticking rings or clogged oil rings can, and have been corrected with MMO.

You can also replace a quart of oil at oil change with a quart of MMO for a few short cycle oil changes and get it out for a few hundred miles of constant high speed freeway driving. Speed, heat, and pressure, combined with strong detergents and good clean oil, can do wonders. 2500 to 3500 miles oil/filter changes with one of the more highly recommended oils will also help keep it clean.
