the stuff i used was thin like marvel mystery oil. claimed to quiet noisy lifters, valves, and something else lol.

i didnt know anything about oil back then, i just added it at oil change and drove for who knows how long. that car is long gone anyways.

I'm assuming that the smaller bottle of Rislone is probably more concentrated then the 1 quart bottle.
It's only an assumption, but It would only make sence. Anyone?

i thought:

a) the solvents had to be diluted with oil, and;

b) seals are made out of rubber, nitrile, silicone, cork, etc. and not styrofoam.

I have used it for 5K kms... added to a fresh mineral 5w 30 Mobil on a V6 GM with hyd. lifters.

I'm using the same car for 5 years so I'm used to how the engine's sounds get different as the oil deteriorates. I can't say CD2 lenghten the oil's performance, but improved it during the use. (Please note that this is a personal observation without test data.)

Anyway, this stuff did not made the oil proggressively darker perceptibly as I was expecting, but it might be because of that the engine was already clean since I change oil often. Mobil -mineral, gets slightly darker after 5ooo kms, it was the same progress with CD2 during 5oookms.

Ticking noises almost gone at the idle, and engine was perceptibly more smooth/silent past 65mph (100kph) speeds. I can say it pushed the usual sound levels of the engine at specific speeds -that I got used to- at least 30kph farther.

I kept this oil-CD2 combo ~1ooo kms longer than usual, after changing it every sound came back w/o the CD2 in the sump again. On the bottle it advises: "Use at least every 2,000 miles". So, could this really be a cleaner?

I think it's main benefit might not be the cleaning eventough advertised as it (but may be the detergency). It is not thick, very liquid. Made this engine perceptibly more smooth at higher revs. and more silent at the all times. I didn't experience any oil use (and I wasn't need to add between changes.)

One of my friends (who advised me CD2) experienced the same things on a 1.6lt 4cyl European Ford.

BTW. CD2 also gives the moneyback satisfaction guarantee.

Does anyone have an engine made of coffee cups?

I drink *&^% cola and know what it does to rusty junkyard engines and don't care.

I don't think that my engine would care what some of the engine flushes do to cups!

I haven't seen styrofoam seals. I also haven't see neoprene/nitrile/rubber/ cups!

The seals may care. My own take is that using solvent products in doses beyond what's indicated could lead to problems, even with otherwise compatible products.

Without knowing the solvent chemistry and seal material it's a little like weighing witches to see if they're made of wood.

I just picked up some CD2 Engine Detergent for my girlfriends POS 1992 Pontiac Lemans (the car BARELY runs... it just needs to last a month or two longer). I think a bottle of Auto-RX is worth more than the entire car so I didnt want to put that in and waste money. A $2 bottle of CD2 hopefully will clean it a little bit. Ive been changing the oil every month and each time it comes out SUPER BLACK so I am hoping this will break more of the crap down.

The car was her fathers until he got a new Silverado. It had sat for 3 years without being run/moved and ran with that same 3 year old oil for about 9 months before I got to it. Its not a pretty sight.

Someone go fill a cup with gasoline, then we will all know that gasoline is bad for your car and is not to be used!

Some gasoline gets into your sump at every cold startup (and may not be fully purged if the vehicle is not thoroughly warmed up). Think about that over 150,000 or 200,000 miles of engine life. I'm not saying you'd want to purposely put raw gasoline in your sump on a routine basis, but is it really necessary to get obsessive-compulsive over the notion of small amounts of oil-diluted solvent as a carrier in an oil additive as it pertains to elastomeric seals whose composition the engineers chose to deal with hot oil and inevitible daily gasoline contamination?
