Does that sound civil?

You have to admit, it's pretty hypocritical of you to mock the composition of Seafoam while at the same time failing to mention the chemical composition of Kreen. After looking at the composition of Kreen, I could just as flippantly say that you might as well pour gasohol and a fuel system cleaner into your crankcase, but that would be irresponsible.

I was genuinely interested in why some people here preferred Kreen over Seafoam based on the actual SCIENCE of it. This is Bobistheoilguy afterall, glittering generalities should have no place here.


I think Trav was trying to have some fun. Kreen sure is growing in popularity here on Bitog. I'd use Seafoam in the gas tank, and maybe via a vacuum line, I would not use it in the crankcase though. JMO YMMV
 
I agree that Kreen is getting popular. However so was/is Auto-rx and MMO. I used both Auto-rx and MMO on my BMW and there was some cleaning. However, there was varnish still there.

Now I am 1200 miles with 16 oz Kreen in the BMW's crankcase. (see my previous posts re observations) I think there is some combining effect by doing all three.

In about a week or so I plan to change oil and filter. I expect the filter (it is a drop in filter) will be a bit dirtier than normal.

Then in about another month I plan to remove the valve cover when I change the plugs and check on varnish.
 
Sometimes changing chemistry is the ticket with stubborn engines. I think after Kreen you should be GTG.
 
I like MMO for price and its ability to gradually clean. I have nothing negative to say about ARX's formulation, I noticed some improvements while using it a couple of years ago(which seemed to fade shortly after use). It's just a bit too expensive IMO. OTOH, people have had good success with it.

I haven't tried Kreen yet, but I think I'll give it a try.

That is probably because it works and we have a mechanic on here who has tried other oil additives and he has really only seen results with Kreen.

Just because something is popular does not mean it has worked for members here. I have seen more MMO success stories as opposed to auto-rx success stories.

We know that auto-rx has problems with removing VARNISH, as far as MMO goes with Varnish I have read posts where people have had SPOTLESS engines from using MMO, this could be that MMO maybe prevents Varnish, as far as removing it, I guess maybe we need some more testimonials.

You bring up a good point, it will be your choice to see what oil additive deserves the most credit.

Let us know what you find.

Let us know what you find, and if you can take some pictures, please show it too the members here.

If Kreen does not work then I guess there are 2 choices, either keep driving the car or get the engine MANUALLY CLEANED. JMO
 
I changed my oil today after running Kreen for 1,945 miles in Valvoline Max life 20w50. I replaced it with Maxlife 10w40 and 11 oz of Lubro Moly Mos2 additive with new Mann OEM filter. The oil seems dark. However when a few drops were placed on white paper and set a while the oil still had a darker golden appearance.

I cut apart the filter. I was surprised there was no gunk of any sort. There were only a very few tiny dark specs in the pleats. This is less than I have seen in the past.

What does this mean? Perhaps it means I have a clean engine and Kreen had very little to clean. I did have a warm idle ticking noise after oil has been the car for say 3,500 miles. This noise seems to have gone. We shall see if it reappears with this fill.

I want to remind everyone I have done two treatments of Auto-RX and I MMO treatment and mostly used synthetic oil or blends in this car for over 110,000 miles.

BTW, does anyone know how to post photographs?
 
Russell, I think you hit the nail on the head when you said this:

You can't clean what's clean!
 
Let me ask a qustion. We have a briggs 16h that has used oil since day one.

How long hours wise should I use this???

Good question, I'd give the Kano Labs people a call, I'd guess about 20 hours would be good. But that's just an educated guess.

It means that the cleaner did not loosen any solid material that the filter would catch. Anything that was able to dissolve in the cleaner came out in the drain oil. Either there was nothing solid to remove, or the cleaner didn't dissolve the material bonding the solids to the engine parts.

In any case, you've done more than your part. Drive and enjoy life.

I plan to take the valve cover off when I change the plugs next month. I will chek for varnish removal at that time. About 3 years ago, there was noticable varnish coloration.
 
It'd be great to see pics when you remove the valve cover. I believe running on blends/synthetic with sane OCIs; aside from apps that are tough on oil/notorious for deposit formation/mechanical malfunction non-related to the engine oil, that you shouldn't typically have much to clean.

If the oil seems DARK, then maybe Kreen is doing something.

Maybe the oil was still good,meaning, you could have gone farther on your OCI, what you see coming out of the oil pan can be different from what you are seeing, I have changed oil that looks dark, but when I put it on my fingers it seems golden, maybe what you saw was what Kreen cleaned out.

I think this probably means that Kreen probably liquified any junk and that is why you are not seeing it in your oil filter.

I think it is time for you to remove your VALVE COVER so you can see if you have a clean engine.

I am guessing that your warm idle tick did not go away from using both of these products and from what I have gathered from your posts that Kreen has corrected the problem, the only thing I can say is that since you have used both auto-rx and MMO then it is hard for us to say how much credit we should give to Kreen.

I will give MMO about 45% of the credit and I will give Kreen about 55% of the credit, the problem with using different oil additives is that we are playing a guessing game, but since you went to Kreen it tells me that you were not happy with auto-rx, which few members have been happy with, then you saw what was going on with MMO, so you gave it a shot, and you saw what was going on with Kreen, so you jumped on the Kreen BANDWAGON, and that is fine since the product does seem to work, but there are limitations to any oil additive, in conclusion, your VALVETRAIN PICS should tell us a story, if your valvetrain is not cleaned up then maybe it is time for your cylinder heads to be removed and get manualy cleaned.

The most dominate issue I had was the warm idle ticking noise after 3,500 miles on a fill and varnish when I removed the valve cover about 2-3 years ago. Thse engine are quite known for lifter ticing. So I just wnated to do all I could to ensure that it was not mechanical in my case.

I do plan on removing the valve cover when I change plugs in about a month. I had photos of the varnish then and will photograph now and compare. I fully expect there will be less varnish.

I also think that the different chemical makeup of Auto-RX, MMO and Kreen helped remove a little more crud each time. I do not plan to use Kreen again in the near future in my oil as I feel that it is aclean as I can make it.

I now plan to use Kreen in my fuel. In fact I put 8 oZ in about 8 gallons yesterday. I will run 16 Oz total through the system and not continue to use it on a regular basis. Man does that stuff smells evil!

A warm idle tick is worse than a cold idle tick, are you sure the tick was not from your fuel injectors.

Could this be from infrequent oil changes.

We shall see what you see, do not feel bad if your expectations are not met.

We have seen from previous posts that arx does nothing for the VALVETRAIN, the same could be said for Kreen or MMO, your PCV System could be clogged, if it is clogged then you could be adding more junk then whatever oil additive will clean up, it amazes me that whenever there is a problem so many members jump to an oil additive to clean things up when they should be looking for the cause of there problems.

Is the cause of there problems from infrequent OCI's for the type of driving that they are doing.

If you drive on the highway then maybe you can extend your OCI's.

Maybe Kreen will clean things up, maybe think about another fuel additive to keep your fuel system clean on a regular basis, because if you keep your fuel system clean then you might have less BLOWBY which will lead to less junk getting into your oil. JMO

That must mean the stuff works, just be careful with your dosage. JMO

I want to clear something up here. There seems to be some opinion that this car is not maintained well. Quite the opposite sine I have owned it for almost 125,000 miles.

All possible filters, plugs and fluids (all synthetic or blends) are changed on a reqular basis. Also belts, tensioners, hoses, and other items changed. Suspension and steering components replaced, Car is garaged, polished & waxed etc. I have a spare set of winter wheels and tires.

You get the idea. This is not my first rodeo with a vehicle.

Are you the original owner.

What are your OCI's like, and how many miles do you drive this vehicle in a year.
