First off...I use Ford's 15W-40 HD oil for diesels and a powerstroke oil filter...the same oil and filter that is recommended for powerstrokes. My truck is an 86 F-250 4 X 4 dually conversion with a 6.9l n/a zf-5 tranny. The truck now has 314K miles on her and she started using lots of oil. At that point I was thinking it was time for an overhaul, but I didn't...
I did a cylinder compression test and was surprised at the results...So much so that I did it again and all cylinders were in the 350-400 range...Good right? I didn't have any oil leaks worth mentioning so I am thinking CDR...I bought a new one, but instead of installing it stock...I relocated the CDR to the intake nose on the breather via a catch can. Now my intake is oil free and dry, but I was still getting more oil in the catch can than I thought was normal, however my oil use went down about half. What to do? Well I heard of autorx but I also heard of Kreen over on Bob is the Oil Guy. I have always been afraid of engine flushing and I was thinking maybe my ring packs were gunked up and not working right and causing excessive blow-by...but why the good compression figures? I was at a loss to explain the excessive oil use...none in the coolant...no oil anywhere except where it is supposed to be as well as the catch can, so I thought I had nothing to lose because of the high milage and decided to try flushing.
Well I bought 3 qts. of Kreen from Kano Labs...I think I paid about $15.00 a quart plus shipping. When it arrived I drained a quart of oil out and poured in 1 qt. of Kreen in the crankcase. I also poured 4 oz. of Kreen in with 16 gallons of fuel. After driving half the fuel out I changed the oil filter and drove the other half of the fuel.
Here's what happened...even before I burned all the fuel and changed the oil and filter...My engine got less noisy, more power and lots less oil in the catch can. Being the worry wart I am...I drove 1000 miles on the new oil change and changed it again...this time I let it drip overnite trying to get it all out. The first oil change was black as black could be and the first two filters looked like they had been on the truck forever. Anyway, by that last oil and filter change my truck was not using an excess of oil nor was the catch can "catching" excessive amounts...Back to normal oil use!!! and still that way today...
Now all I do is add 3 oz to the oil and fuel every 2nd oil change for maintenance. It...the Kreen worked for me...will it work for you? I don't know, but for me it was well worth the chance vs. overhaul....Maybe I'll get another 100k before I do need an overhaul...maybe more...Well there's my story...
