i want to try this stuff out! the first treatment is to clean out the asperities in the metal, then oil change, then add new oil with the final treatment... this treatment seals up the asperities... pretty good in theory!

Pretty good in theory... but something about it makes me leery. Main page last updated in April, poorly done frames-heavy website, FAQ that hasn't been updated in nearly two years, and "copyright 2004" on the bottom of all the pages...

Maybe they just have a pathetic Web department, but I dunno.

[edit] Oh, and their most recently listed "press release" is dated 2005.

I tried a similar product some years ago (Restore). I did a compression test before and after. There was no change in compression, no reduction in oil burning - exactly what I expected. As far as their claims, this ferro-silicate they are talking about doesn't really seem to be a product I would want in my engine. Reference these two sites: http://1828.sorabji.com/1828/words/f/ferro-silicate.html and http://cat.inist.fr/?aModele=afficheN&cpsidt=15297005. I don't think a salt like substance that can be used as a substitute for sand in concrete is something that I want in my engine.

well i'm eventually swapping out my 1.6TD, and maybe i'll try it just before :wink: or earlier...

i've heard good things about engine restore. not a miracle product, but i think it just thickens the oil up to give better compression...

Do a search for Schaeffer Oil. I think they have superior products. Look at the Moly E.P. Oil Treatment. It could buy you some more time.

both those products reduce the friction yes... but the RVS treatment actually fills in the asperities of the metal surfaces. in theory it could restore factory clearances, and thus compression etc.

i've also heard some negative things about moly under extreme engine temps...

Good word, asperities. Never heard it befor. Sent me running for a dictionary. :wink:

The Graphics on thier web page are pretty nifty. But that RVS treatment looks like snake oil to me. Typical 'Engine rebuild in a bottle' bull crap.

If thicker oil was the answer, why not go 50/50 engine oil and 80-140 gear lube?

because mileage would go down significantly, and cold starts would be very detrimental unless the oil left a good film on there that really 'stuck' to parts :lol:. Ford reduced the weight of oil in the rear diff's of their trucks so that they could meet fuel efficiency standards. only problem is that they blew up at around 100,000km's. :roll: :lol:

i don't know too much about chemistry, but it seems like it has some merit... they talk about their product bonding to the cyl walls... any chemistry majors out there??!

Ah, I took some college chemistry, and it still looks like snake oil to me.

If it was effective enough to reduce the bore diameter to a point that it made a real difference in a worn engine, there should likewise be a stern warning on their web page and product packages to not use it in a healthy engine, as the 'bonding' action would reduce the bore diameter and seize up the engine.

Or build up in places it isn't suppose to...
