Hello all,
I will keep this post brief and on point (i hope).
Engine: 2004 Cavalier Coupe 2.2 Ecotec with 160k. Current hwy mpg 41. 5 speed stick. KNN filter.
Bought this car from a woman I know who could not drive anymore, about 8 months ago. Due to massive medical bills and a chapter 7 I needed something cheap and she had put quite a bit of $$ into it but had let things slip for a year or 2.
I knew there was sludge built up in the engine due to the smoke coming up from the oil fill hole. Car was using about a quart every 1500 miles. I started using 10/30 not 5/30. Still, mileage was great.
One thing led to another and I bought a quart of Kreen.
Initial app was a pint after I changed the oil. During the first 4-500 miles I checked the oil several times and it got dirty quite quickly. At 500 I changed the OF cartridge. the old one was heavy and caked with crud unlike previous changes. Added another 8 oz to the oil and the remaining Kreen to the gas only filling to a little under half. At 1k miles I changed the filter again and it was heavy and caked with crud. changed again 1500 and the filter was "normal". no crud and half the weight. did add 1/2 quart of oil and checked each few hundred miles and changed at 3k.
During the time from application to drain here is what i noticed as time went on:
Smoother running and no clatter at cold start.
Temp dropped from just above 195 degree line to just below, even when idling.
Smoke from oil fill hole was gone and so was burning smell.
Only oil added during "cleaning" was the half quart at 1500 miles.
Engine is quieter overall and seems to have a bit more power. Wife noticed as well and she had little info on what I was doing.
After cleaning and fresh oil:
After 4k of driving oil consumption dropped from 2 quarts to less than half of a quart.
Mileage has increased from about 38 to about 41. I checked this several times on a few long trips of 300 miles.
Would I use this product again and recommend it? yes.
I would tell anyone to change the filter a few times as I did, if possible. For this engine the cartridge is top mounted and easy to access.
I know that some out there would never use anything in their motors. I am not one of you but I respect your decision. I do believe that there is a ton of snake oil out there on the shelves of parts stores.
