With RVS, since the diesel pump was being "repaired" by the RVS, the fuel consumption dropped 14%, within 1000 miles.
After that, I put it in the differential, transmission and engine.
It has really made a big difference, but not as big as when I treated the diesel pump, since it was mechanically "shot".
Of course, I should have taken a compression test, dynoed it and done exhaust testing, but it cost too much.
Besides, I did contact other RVS users in Sweden, and they were very positive about it.
Then, I decided to give it a try, and it turned out that they were right.
This is the best additive I have tested, without any doubt.
And yes, I have been testing several, including ARX.
RVS simply works, even though I must admit being surprised that it does!
Hm I wonder what would results be if you have left the pump alone and treated just engine as you did with Xado and Restore?
I used Restore about 20 years ago in a worn engine that was
down on power. It did what it claims to do, improve the compression. It also clogs the oil filter which must be changed shortly after treatment.
But the increased compression didn't last long, maybe a few thousand miles, then you had use the product again. It certainly doesn't permanently fix the problem. It also didn't reduce the oil consumption. In it's favor it's not expensive.
RSV sounds interesting, might be worth trying.
