i changed the oil on my car, added a nice oil treatment by pro long and all. but heres what happened, some idiot left some oil bottles next to the new ones with old oil in them from previous drains. It could either be old engine oil or possibly tranny fluid(out of my car) thats the only thing it could be. I know if its old car oil, its ok, cause i only put in about 4 or so table spoons before i realized its old, black oil. But what if it was the tranny oil out of our 5 speed? If i put 4-5 tablespoons of it in the engine, along with 5 quarts of brand new, good oil with an additive, do you think this should be ok???? Help me out guys ASAP

If the oils are a different weight, like if you put tranny oil instead of engine oil then there is the danger that it could foam and push air through the system rather than lubrication. I would think even a small amount may do that. If it ends up you just put a bit of dirty engine oil being put back in then no big deal.

anyone else, i only put a bit in, damnit, im pissed off, i spent like $20 on oil and another $6 for the prolong additive and $6 for the filter, i dont wanna do it all over again just because of the little bit of ****ty oil. SO if it was just a bit of our mtx tranny oil, could it possibly do any damage???

I would not have put prolong or anything like that in my car but whatever, you should be alright on the mixed up oil.

I agree with the foaming. I don't know how ATF would do in the oil. I'd drain and flush it if possible. It's only $20 for oil an filter. Better than $2500 for a new engine.

Also I would advise staying away from engine additives. Most use high levels of chlorine that does make it an apparent better lubricant but chlorine is highly corosive!

Oil companies spend a lot of time and money making sure that their oil works well.

damn, so atf oil could mess your engine up huh? Even just a little bitty bit? Hmm...im gonna make sure it was tranny fluid first, my dad's out of town, he might know what was in those bottles. Damn, anyone else wanna give me input. Ive been driving around today and everything is fine, but who knows....

No, ATF will not damage your engine in that small amount. When I would do oil changes on some of my previous beater vehicles, in order to help clean the crankcase, I would put anywhere from a 1/4 to 1 full qaurt of ATF in with my oil for the 3000 miles. It helps clean the engine oil system and better yet, it has detergents that help to remove the crud completely from the engine.

If you are seriously worried, drain it, the pro long does nothing but empty your wallet, so you will not be wasting it any more than you already have.

5 quarts seems like a bit much- when you checked the dipstick what did it read? It seems like keeping it at low to mid level on the stick works best for the zetec. I only plan on puttin in 4 quarts of redline 10w30 at my next oil change and if the stick reads at low or lower then i'll buy another quart and add 1/4 quart.

Prolong is a mis named product.. It should be so long ( to your engine ) It actually reduces the life of your bearings...If you are in doubt go to motorminute.com and see if you can get their report on it...Spring for the money and just use REAL: Syn Lubes like Mobil 1 and Amsoil or Redline or Royal Purple... The rest of the stuff is crap ( and illegal to call synthetic in Europe )

Naz you are too nice a jetter ( ain't we all ) to crap out your engine... get that sh*t outta your car NOW!!

Actually, Prolong has saved my but a number of times. The first case was when I first started driving, my alternator belt broke while driving. I was young and didn't know what to do but I kept driving. This belt also drove the fan and everything. The car would barely run in second gear. Keep in mind I was driving uphill for a couple miles to get back to my house. The car was studdering and shaking all over the place. the only gear it would move in was second. So I kept driving, not sure what to do. When I finally got home, smoke was pouring out of the engine. I told my dad what happened and he said the engine was toast. He new without a doubt. He is skilled with engines just so you know. We let it cool down and he didnt think it would even turn over. Sure enough it did. It took a little coaxing bu it did. The thing is, We had just added the Prolong to the car a few days earlier. I'm a believer now. The second story isn't as good and I don't want to type anymore.

BTW none of this was in my focus. I have since become a stickler for car care and I now know much more than I really need to. I was so new to driving at that time that I didn't even have my license. I was a few months away from 16 and my parents told me to go down the hill to get milk.

Oh yeah, I just remembered, it actually broke like right after I left the house but I didn't think anything of it. I left the car running while I went to the store (little country store so it's not unusual to do that)

Those additives are nothing more than snake oil.

From a previous post of mine: "I'm glad you haven't had any problems... but know this: Back in 1992, the National Advertising Division of the Council of Better Business Bureaus asked Petrolon (Not Peleton heheh) to discontinue such assertions (such as improved mileage, reduced wear, and just about all of their claims) due to lack of substantiating evidence. In other words... they were sued for plain out lying. Now they are more or less like those psychic hotlines. They still make lot of money, but have to advertise "for entertainment purposes only". But it has a placebo effect for some, so perhaps its worth it for that.

<A HREF="http://neptune.spacebears.com/cars/legal/s50fcn.html" TARGET=_blank>AGREEMENT CONTAINING
CONSENT ORDER TO CEASE AND DESIST</A>

--------------------------------------------------------------------------------
Part III of the proposed order prohibits respondents from representing that any Slick 50 lubricating product for use in a motor vehicle, other than an engine lubricating product, reduces wear, extends the life of a part, lowers engine temperature, reduces emissions, or increases mileage or horsepower, unless, at the time they make the representation, they possess and rely upon appropriate, competent and reliable evidence that substantiates the representation.

Sooooo... it does... absolutely positively NOTHING. At least nothing positive they are allowed to claim anymore.
My father has also worked extensively in the oil and lubrication industry, and also strongly warns against such teflon additives in oils. They can actually be detrimental in that they clog the oil filter prematurely. And the physics behind it will physically not allow the teflon to bond to the metal. I would recommend avoiding ALL oil additives from every article I've read on the subject. There is a LOT of chemical engineering that goes into these additive packages that are in a specific balance and already included in each oil. Increasing the effect of one of the additives can have a very detrimental affect on another. And most importantly remember that its the OIL THE LUBRICATES. The oil that can do this with the least additives, is the best choice.


Although this applies to slick 50 and any other name the product might be sold under, Prolong really isn't any different. If you were really into car care and knew more than you needed to, you would avoid this stuff like the plague. You owe it to yourself to research on the net for one hour to .

Slick50, Duralube, and Prolong are constantly being sued up the @ss. How could they possibly remain afloat? Well the revenue from misinformed consumers is outweighing the lawsuits so far.

Currently the manufacturers of the ProLong engine additive have been dealt a smack in the face by a Consumer Reports Magazine report into their product. CR attempted to reproduce the "no oil" test where all the oil was drained out of an engine which had been treated with ProLong, and then the engine was run. CR managed a maximum of 13 seconds running out of each of two engine before they seized up, welding the pistons to the barrels. The case is being brought to a Federal Commision for prosecution for false advertising claims. The engines come equiped with hydrolic lifters that simply won't function w/o oil. Prolong, in their tests, modified the engines to operate w/o oil in an attempt to mislead the public into believing that the engine was able to run simply on the "treatment" of Prolong. And it has been scientifically proven that any additive that contains PTFE (Teflon) will not achieve high enough temperatures in an automotive engine to bond to metal (if your engine got that hot, you could say bye bye engine within nano-seconds). Therefore this substance is suspended in the oil and is known to prematurely clog oil filters. Dupont (one of the largest manufacturers of PTFE) published their findings against this and went on to threaten lawsuits against any of these companies that used the Teflon trademark name and refused to sell their PTFE powder to any company with the aim of using this as an engine oil additive. Unfortunately, the oil additive makers sued Dupont and the courts required Dupont prove conclusively not that PTFE would not work as an additive in automotive engines, but that it was very harmful to the engine and therefore excusable to refuse sale based on consumer safety. Dupont had no desire to invest more resources into this and consequently continued sale of PTFE to these additive companies against their wishes. This was not due to evidence proving that these additives worked or were not harmful, but instead are simply innoscent until proven guilty.

Hopefully the current lawsuits by consumer reports will amount to enough to actually put a dent in Prolong's wallet. More likely than not, they will continue selling them though, and simply have to alter their advertising campaign.

IMO uninformed consumers DESERVE what they get, but the public can't really be required to investigate EVERY little thing they purchase (like over the counter drugs for example), and therefore we need organizations to help sue these companies that are raping the less knowledgable public. But what ends up happening? Even when someone finally invests a lot of money (it costs BIG time to fight these big company's teams of lawyers) to prove these claims are total BS or harmful to the public... they just slightly change their act perhaps with a slight disclaimer. Nothing pisses me off more than those psychic hotlines for example that make totally bu****t but then at the bottom it says "for entertainment purposes only" and then its ok.

well theres always the other extrem in disclamers, Rx comercialls, almost 3/4 of the comercial is a disclamer now (i realize Rx is a little more serious matter but i would think/hope people could realie on doctors to tell them the side efects?!?) but i guess it works. people are scared into finding more out about stuff before they use it.

how are you so sure that it was the prolong that kept your engine from not running?
