Some years ago I had an R32. It smoked a little bit, when you take your foot off the accellerator, so the issue was just valve stem seals. So I went with some prolong. That was the oil to have in your car, after all, the tv said so.
It did not stop smoking immediately., but after around a week it actually did. And it only did so from oil starvation.
In my mind the car suddenly went very well... well, for about another 3000 km when 3 bigends and a main suddenly failed. Engine moer toe. When we drained oil, there was a black sludge of about 500ml that came out first, and only after that, the oil. The filter was also just one pot of sludge. In the end I had to get a new shortblock sub, because the bearings seized on the crank and started turning in the block.
I will NEVER use aditives again, unless it is specifically advised by the manufacturer, like for instance the friction modifier on the diffs of my jeep. I will for the rest of my days advise against it. Lessons learned
The sludge was there all along. The Prolong just loosened it.
Most of these additives have have a de-sludging agent. Thus it wlll dissolve the sludge. But big chunks will come loose and clog things.
Just one thing to keep in mind, is that most of these additives just have a lot of chlorine. Works well to make things slippery, but is extremely acidic.
The Uniglide is not. We have a TBN(PH) of 7.
As far as prolong goes , it was a ptfe product that blocked oil filters . Did f u c k all to loosen sludge
The cleaning / flush types are mostly paraffin and did loosen sludge that would then block your oil filter , and were also a bad idea. Removing the sump and cleaning it was a far better idea . But those never claimed to add lubrication , and indeed , to change the oil and filter not long after introducing them .
I’d love to comment on uniglide .
But without some information on its contents , no one can .
Not even their salesmen . Not those with a clear conscience anyway .
