I've heard good things about this product from people I trust before.
That being said; how is it possible for a compression ratio to change? The atcual compression in each cylinder will change because of the "leaks" generated from worn parts. The compression ratio is the difference in cylinder volume at TDC and BDC. I am only seeking knowledge. I'm not saying your wrong. Can you share the math with us? Or is it too complicated?
thanks,
the compression ratio does not change. as the motor ages and wear, it builds up some deposits, and can also generate small leaks in various places in the combustion area. thats why the pressure generated in each cylinder varies and decreases over time. the 'restore' product, and similiar items, work to remove the deposits and seal the small imperfections in the cylinder that allow the pressure to drop. thus, you will usually see a gain in cylinder psi, as was posted.
technically, then, the compression ratio does change. but its not a set number or a linear decline over time, or consistant throughout all the cylinders. the 'compression ratio' is simply what the motor was designed and built to produce.

I have used RESTORE in some older engines that I had over the years, It most definity returns the lost power, However I was told by an ASE certified mechanic that It clogs your oil filter. I havent used it since for that reason. Has anyone else heard of this happening? What do you guys think?

No, No, I was'nt trying to be negative. i mean I love the stuff, it works great. My dads 1986 ram with a 318 has 213,050 miles on it. It smokes(valve seals) and had two cylinders under 100psi. After adding the restore,about 150 miles later the smoke notciably lessened, all the cylinders showed right around, (give of take a few psi) 130psi. The stuff is truley awsome. A friend of mine, (ASE mechanic of 9 years) told me it clogs oil filters. I just wondered if anyone else knows anything about this.

I just got my Ram this past July. I read this thread just before I did my first oil change so I decided to try it. I noticed a big difference in how easy my engine was idling and I actually felt a little difference in the power at the rear wheels after about 300 miles. I'm coming up on my next oil change so I gotta go get some more!
Somebody answer me this, how thick is this product when you pour it out?
Years ago (and they still sell it), the big thing to restore compression was 'Motor Honey'. It does just what the name implies - it thickens up the oil, creating a better seal of the piston rings in the cylinder which equates to less oil burning, higher compression, more power, etc. (they always throw improved miles per gallon in there too!).
Just wondering if that's the case. If not, how does Restore say their product is able to achieve these improvements?[sm=confused06.gif]
The engine in my truck is in great workingcondition. Should I use it in a fine working engine with no problems at allbut with 97000 miles on the odometer?

if it were going to clog your oil filter, you'd see a drop in oil pressure...
one suggestion I can offer is to use the MMO for about 10k miles, then go to the Restore. The MMO would clean the insides, then the Restore could fill the gaps as mentioned.
steve, it's kind of funny you just mentioned Marvel Mystery Oil as I was just thinking about it as I read this thread. I've used the Restore stuff in every car I've ever owned. However, I just use it for the first couple oil changes since I don't know what the engines been through and then maybe every 10th change or so. I just got my 98 Ram a couple weeks ago and wasn't able to get my hands on any of the Restore (I live in a pretty rural area) and a buddy of mine suggested MMO. I'd never heard of it, but he says it's so good it will unlock a seized motor. Hmmm. I definitely don't have a seized motor, but it is burning some oil. I think I may try it for the first two changes and then the restore for the next like steve mentioned.
I tried this stuff once.In my 89 XJ.I had a lifter tick and it had around 150K on the clock.I put the 6 cylinder can in.100 miles later I had no oil pressure.Clogged something for sure.I drained the oil(which was fresh) and put back in regular oil,New filter too.Oil pressure went back to norm and everthing was well.It looked like bee's took a honey dump in my filter.I wont try it on my truck thats for sure.
