How long would YOU leave (8oz, 12oz, 15oz, 32oz) KREEN in for? 10 minutes? 20? 30? 1000 miles? 2000? .....

And, would you add it to a HOT engine, or COLD?

Just asking because I heard it is really good. Also, more effective if you put half in the gas, a la Seafoam... ?

I am using one pint of Kreen, (1999 Subaru), in the last 1000 miles before I change oil/filter.

I will do this once more, then I am done, clean or not.

1/2 pint of Kreen the last 1k before oil change every 2 years/30k. I tried Kreen in the gas, followed by a PEA additive in the gas for an occasional rough idle/misfire issue. Gone with the PEA gas additive, has not returned. So I use a 10oz Walmart bottle of techron concentrate plus the last 1/2 tank of every 7k OCI.

Putting Kreen in the gas is a waste of Kreen, I think.

Depending on your engine dirty problem, there are lots of "ways" to Kreen your motor.

I had success in my truck dumping in 1 quart for 1000 miles. Changed oil. Then ran a pint for a 1000 miles at the end of the next two OCI's.

I like to dump in in the engine cold. Kreen is pretty volitile. I'd hate to dump it in and have a good portion of it flash off in the bottom of the oil pan. That's just me tho.

I don't see how this would be a good idea. Every additive I've ever see directions on says to add it to a hot running motor.
How exactly would it flash? Are you suggesting there is no oil in the pan while the engine is running?

Ght. You will have the cleanest Volvo engine on the planet that has chipped pistons and bent valves. But it will be clean,as it heads down the road on a tow truck en route to the auto wrecker.
With all these threads you've started showing us all your purchases and such,I wonder if you added it all together you would have enough to change that timing belt by now.
Just a thought.

Clevy, can you tell me more about the chipped pistons and bent valves? I don't know anything about how those things get that way, is why I am asking!

I think the T-belt is coming when it is Inspection time. I have a feeling.

I don't do this EVERY day... (Italian Tune-Up)

I think it's best to follow the manufacturers recommendations that are printed on the bottle. Someone recommended 3oz per quart of oil. I've been adding 12-15oz of Kreen to my 98 Toyota Camry V6 that's going through a Kreening process.

I started with a fresh fill of oil and added 12oz. 1,000 miles later, I added 15oz. I'm now nearing 3k on the fill and don't know whether to dump the oil or add more Kreen and run it some more....

Clevy....you missed my point.

When I say flash, I mean, the Kreen has a very low boiling point...meaning, it's volitile. So, dumping Kreen into hot engine oil would cause it to vaporize (ie, NOT stay in the oil).

I want the Kreen to stay in the oil for as long as possible. Which isn't very long under normal driving conditions. I want the Kreen to stay in the oil so it cleans out the areas of the engine that are in contact with dirty oil and sludgy crud.

However, I do think some vaporization is helpful. It will help clean the intake and the PCV system because of this, which is a positive side effect. But I want the majority of my Kreen to be in the oil to do it's cleaning.

If you dump Kreen in cold engine, and go for a 3-400 miles high way drive, most of the Kreen has probably gone out the tail pipe when you get home.

I add Kreen to a cool engine, fire it up and drive. I remember back in the day, people would heat up a bottle of STP, and pour it into a hot running engine making it easier to pour and mix better. I don't see the need to do that with Kreen. Opinions vary.

I'm not sure V has gas for 3-400 miles!

So, now I am thinking to put it in a HOT engine, since I really wanna clean the PCV?

There was one time I did that, I heard sirens in the tunnel. ........

Yeah, I have to say.. Getting everything REALLY hot/circulated/you hear that turbo spool, sometimes blow off its boost, and tires chirp because you took a turn real hard.. THAT is an IT-U. Top Gear.. is a snoot British show, and the American version is so bad...

Maybe you are talking more about runs like this? (I have been cutting down on how often I do this.. But, I have to say: The car likes it, and runs better afterward. I honestly think I am "blowing out" something that isn't supposed to be there.)

It will clean the PCV when the engine gets out and the Kreen begins to become gaseous/vapor.

It will get hot once you start driving flash off and clean the PCV system. Honestly I don't think adding to a hot engine or a cold engine will matter, if anything adding to cold engine is probably safer.

I dont think it really matters when you put it in but I like to drive the car right after I put it in to make sure it gets mixed in the oil. Dont worry about how long because it will evaporate after 500 miles or so
