I am NOT a snake oil guy...I hate all the additives that everyone tells you put in your engine for this and for that. I somewhat believe in seafoam...but generally the rest are crap.
Well....I am looking at a top end rebuild sometime soon due to some noisy lifters. I wanted to extend the time until I do it, and did some research...I settled on this product:
Restore Engine Restorer and Lubricant with CSL 6-Cylinder Formula

Well...I ran Mobile 1 Full synthetic with some MMO for a week....did nothing to help, so I went back to Rotella 15w-40 and added a can of the above.
It is a blue substance, not a viscosity additive, but claims to be able to fill in cracks in metal components, quiet chatter, and help leaky seals. Claims to restore your engine as the title suggests. Kinda thick, but not as thick as, say, Lucas.
5 qts oil, and 1 can Restore.
IMMEDIATELY upon first start, my ticking/knock was GONE. It was absolutely amazing, and is only $8.97 at Walmart.
I am impressed thusfar, but will continue to update as to whether it is a very temporary, or longer term solution.
Thanks....I rarely endorse a SPECIFIC product, but I am sold on this one.
Description from manufacturer:
Restore Engine Restorer and Lubricant is a high performance oil additive that increases compression in older high-mileage engines. The unique CSL formula fills worn areas of the cylinder walls to reduce blow-by and restore compression to near original levels. Restoring cylinder compression improves combustion to increase horsepower, reduce oil burning, maximize fuel mileage and restore peak engine performance. In addition, it provides excellent EP lubrication to help protect engine components from excessive wear under severe operating conditions.

Interesting. I've seen this stuff on the shelves but I did notice when doing some light research that it didnt seem very snake-oily (eg Lucas and Teflon additives)
When you ran Mobil1 did you use the TDT 5W40 stuff or one of the W30s?
And what filter have you paired with all this?

I bought a Nissan pickup when I was in high school with 300000 miles, and I used the above mentioned product with great success! I don't know what's in it but it actually worked on that high mileage engine!

I used to run this in my old chevy 6 cyl. Made a big difference. The truck was on it's last leg and I only used it for trips to the landfill and for lumber. Just wanted to keep it going. But with the Restore in it the compression came up and the smoke went almost away. Ran it for something like 3 years and didn't seem to hurt the motor. Made a diff in my old smoky lawn mower too.
