CD-2 Detergent + Oil.

[ericcarr2000]

Ok recently I added some of that CD-2 detergent to "try" to quiet down my, what I thought was lifter, ticking noise. Once added, that didn't take care of the noise so on with the diagnosis process. Well...In the mean time I changed my oil to try to get that detergent drained out. When I drained the oil I couldn't believe on how it looked. It almost had a thinned out muddy look to it, brownish in color. Is it normal for it to look like that, and how many more times should I have to change it to get it back to normal?

Wrench in a bottle usually doesn't do much. Did your oil have a lot of "creaminess*"? It sounds like you could be describing water in the oil.

Howdy,


CD-II oil is an obsolete API designation (introduced in 1985) for 2-stroke diesel engines.

CD2 is a snake oil sold by many auto parts outlets that make the following claim.

Designed for cars with over 40,000 miles. Comes in 4, 6 and 8 cylinder formulations. A product that?s right for any 4 cycle automotive engine. Contains Cerflon, a ceramic reinforced P.T.F.E. compound. Cerflon is a thermally stable concentrated micronized friction and wear modifier. It reduces wear and prevents metal to metal contact and surface scuffing. Today?s most recent automotive oil certification requirements have lower anti-wear levels that may not be right for an older or higher mileage car. CD-2 Adrenaline Power Restorer with Cerflon contains up to twice the amount of anti-wear, anti-oxidants, anti-corrosion and detergent additives as compared to regular motor oil. These additives provide extra wear protection, especially in critical valve train and bearing components and engine cleanliness in hard working engines subject to extreme operating conditions. Conditions that can promote the formation of harmful acids, oil thickening and engine sludge which can lead to clog.

• Replenishes detergents and dispersant in your motor oil
• Cleans all internal engine parts
• Prevents rust and corrosion
• Restores pep and power
• Replenishes additives to worn oil

I have no idea why you would think it's "right" for a gasoline marine engine to "quiet" lifter noise.........

It almost had a thinned out muddy look to it, brownish in color.

That's usually described as evidence of water.

My suggestion would be to pressure check the cooling system for leaks........and to refrain from trying to fix your engine by pouring something into it.....

Let us know how the pressure check turns out and someone here will have a "next step" for you

Re: CD-2 Detergent + Oil.

Well I know I have no leak in my cooling system because my motor utilizes a closed cooling system, there is a heat exchanger that aids in cooling the motor. The sea water enters the exchanger, the antifreeze from the motor enters the exchanger. My antifreeze level has not gone down one bit so I know its not my antifreeze.

Hmm. Well, you may still have oil contamination (if not only from the "stuff" you poured in!)

I'll fall in line with the change the oil (sans the "stuff") and see what happens.

Water intrusion can come from other places. .....including riser gaskets if they leak back into the exhaust.

That usually doesn't allow enough in to make it visible in the oil though....

You didn't indicate what engine you have. If the oil smells like gasoline and /or is really thin, you could have a failed fuel pump that is allowing some gasoline into the oil....

Ayuh,... 470s leak at the cam seal,....

Re: CD-2 Detergent + Oil.

Yeah that would be ok, but remember as I stated before my antifreeze level is NOT going down, so Im just hoping that the next time I change my oil it will clear up.
