Kreen Update

[steve20]

Something negative has obviously happened to the engine in the Corolla. I am very surprised none of the users who extol the virtues of Kreen have not stepped forward to voice their opinion on the nagative outcome.

Are only positive threads related to Kreen worth talking about?

OP you state the previous oil consumption was 1qt/5K miles. Has that been from new, 15K 25K, etc?

fuggedaboudit.-----????? That is easy to say, it's not your engine !!!!!

Well, Kreen is a different chemical from the previous 90k miles, right?

If I've learned anything on this site it's that changing from one chemistry to another 'will' change the consumption upon initial use. I'd imagine your consumption will settle down, but you could consider changing to another HM oil brand to see if another additive composition will change the consumption again.

However, might it be worth checking the PCV valve? If this is occurring on mostly highway driving, what are the RPMs at cruising speed? That may clue you into a higher/lower vacuum service use and give an area to look for consumption contribution.

Thanks to Jim for a meaningful contribution.

One negative outcome? I'm sure there's more than one. Just by it's intended use Kreen dooms itself to "failure" as it is unlikely to be used on a newer engine, only an old tired one.

I've got about 6 positive outcomes here, too many to sit and type out individually. But the two most dramatic are posted.

Kreen continues to be a wonderful product that will always be on my shelf.

Currently on second OCI after a 1500 mile 1/2 qt Kreen run. So thats 9k and 2 drains ago.

The good:
Engine runs excellent, very quiet, oil is much cleaner through the entire 7k OCI

The bad:
The engine now has a voracious appetite for oil. Especially on the highway. Started shortly after the drain of Kreen. Went from 1qt every 5k to 1qt every 2k. Upping from 5w30 to 10w40 hasn't slowed it one bit.

The variables:
Known valve seal issues for 90k miles. Let it go because I was burning only 1qt every 5k prior to Kreen. Had been running M1 HM 5w30 for the entire 90k, so the engine was relatively clean. still running it now, topping off with M1 10w40 to try and slow it. No help. I suppose I was asking for it adding Kreen with bad seals. But with 90k of stable oil consumption I assumed nothing much would happen. Clearly something has, I waited 2 oil changes and 9k to say something.

So...after 90k running M1 HM the leaking valve seals were being held back by crud? or were these seals in their weakened state vulnerable to the harsh solvents of Kreen?


Actually this kind of issue happened to my Echo, and when it goes to 1 quart every 2k, I just dumped the engine and get new one. On that rate, the problem most likely is not about seal or PCV anymore, and to tear down, clean and install new ring, seals, and piston may not worth compared with change the engine

Based on the recommendations on this thread I used Kreen on my 92 Accord with 275k mi recently. I have always done regular 3k oil (non-synthetic) changes in the past, after the treatment the engine has become noticeably smoother, quieter, idles better, revs a bit more freely, and the car now rolls so much smoother under gear breaking when coming towards a stop. My car never had an oil consumption issue before, i have not noticed anything so far. Applied only one treatment (12oz / 4qt), 1k mi before the last oil change which was approx 2k mi ago. Just wanted to share my experience.

Is there any way I can get my hands on some Kreen up here in Canada?

Try yo order from kanolabs.com to see if they ship to Canada. They don't ship to California.

No option for Canada, US only. Is it only available directly from them?

Yep that's pretty much the only way to get it that I know of.

Are you near Int'l Falls or Baudette??

Unfortunately I'm not. I'm located in Eastern Ontario, just south of Ottawa.

Thanks ltslimjim! I waited a while to confirm this. Yes, the post-kreen increase in consumption is highway driving only. I replaced the PCV 2 years ago with a Napa aftermarket. Its a different design. Larger opening for PCV gasses, very loud ticking. I am going to buy an OEM Toyota PCV from the dealer with the small opening. Need to rule that out.

For people reading this a clarification: I am not saying Kreen caused the increase consumption on the highway, I think it exposed the old engines weaknesses and repairs that are needed. No different than the "synthetic oil causes leaks" myth. I mentioned the engine needs valve seals in a prior post.

The point I'm raising is..for older engines with known consumption/leak issues, a cleanup may expose more problems than it solves depending on whats causing it. Try to figure out what it is before tossing chemicals in your engine blindly. If the engine is simply dirty, coked rings, no known mechanical issues, no external leaks, I think Kreen is a great additive for preventing future problems. I continue to use Kreen on other vehicles. No reported issues with them.

Will report back after testing OEM PCV for a while.

Thanks to Leaky seals for a thoughtful and well-reasoned post.

It is indeed likely for Kreen to exacerbate pre-existing issues in an old and tired motor. It should not surprise anyone.

No bottle of magic can fix everyone's issues!

Great points! I think changing the PCV valve back to an OEM valve is a good idea. Aftermarket PCV valves have been hit or miss for me over the years. An E-150 I owned started using oil with a change to a Fram PCV valve. I tossed it, went to the dealer and grabbed the Motorcraft PCV valve and stopped using oil. That might not be the case here, but an OEM PCV valve could help. Keep us posted.

Well, after reading all this stuff about KREEN, I just ordered some for my 1999 Subaru with 176,000 miles.

We shall see!

Where to buy? Hope this isn't another Auto-RX that was designed for sealed machines, not air-sucking engines.

You have to order it directly from Kano Labs, online. The product works as advertised, here's their guarantee:

"Try any Kano product with no risk to you. If it ever fails to meet your expectations we will immediately cancel the charge. It costs you nothing! ------ There is no risk to you!" ------

Not at all. I have used both long term. One works as advertised or better and one doesn't work at all.

As Frank pointed out one has a real guarantee the other you better get ready to get in the weeds with the owner.
