A year later and I just dumped a bottle of this into my crank-case.
Think a few of you did as well.

Reports?

Hm, I see I bought some of this stuff, I don't recall using it but I don't see it in my box o' filters either....

I wonder what happened .

Sorry I dropped the ball on this one fellas .

I'm also very interested to hear if anyone has reports after adding to their Mercedes Diesel.
My 6cyl Lexus is also consuming oil too fast, so I may want to try some in there.

Can this product do any harm besides wasting $11?

From what I've read, no.

My 616 was drinking oil at highway speed. Changing the stem seals stopped that cold. I have pretty high and even compression numbers but a bit of blow-by.
Thing is, even a 5% increase in efficiency on a 72hp engine would be noticeable.

It was 7.50 on Amazon so I grabbed a bottle, I guess for a 5 cylinder you just round up to the 6 formula. My lowest cylinder was 320 psi cold last I checked. I'll put it in at my next oil change. It probably won't do much.

This thread is old. I think the reactions you see are what you get.

I had a vw dasher with a diesel that had been run low on oil. It burned a quart between fillups so on a long trip I had to stop at half a tank and add oil. I drove it all over the country that way. I used restore many times. It would initially drop oil consumption by half (quart every 400 miles) but consumption went up again after about 3000 miles. This has been more than 20 years ago, but my memory is that a second dose in the same oil wouldn't change consumption. You had to change the oil to see the effect or dump it in oil that you hadn't yet used restore in.

It's only a matter of time....

Anyway, I put the stuff in my Lexus that is consuming a quart of oil per 1k miles (a known issue for these engines). I doubt it will do anything, but it's an interesting experiment.

Do you doubt it will work because of the narrow bandwidth it seems to service (ie, cylinder walls)?

What does the filter look like after this? Maybe change just the filter and see what happens.

Back in the day like gen 2 5.7L quart/k was considered normal GM consumption. That was also when they started with the 'energy efficient 5-30' BS. mob1 15W50 reduces consumption and increases hot pressure in almost anything.

I had put a can into my 190D last April. The car died two weeks later. Probably unrelated.

I remember when using a quart of oil in 500 miles was considered acceptable as long as it always started (even in January) and ran well....

Times change, I'm glad they did .

Reviving this thread with an update:
I put a bottle of the stuff in my 2007 Lexus GS350 with 141k miles. Performance felt the same, but, I did enjoy a consistent 1-2 MPG improvement for about the 1,000 miles that I've been testing.
With current gas prices, that saves me $10-$20 in gas per 1,000 miles.

So, it would be interesting thing to test in my old diesel. Should I hesitate to do so?
