I have to wonder how long it would take of constant use of some of these shelf additives for evidence of bore polishing and other non-repairable damage to crop up .... if it's going to .
I'm not certain analysis can tell if the dispersant is being jacked with as just one example . Not additive related but I have seen an analysis of oil that looked fairly good then the oil pan was dropped and the bearings was coming apart .
Can anyone else name off any tell-tale signs of potential harm from long term use . Burning oil would come fairly gradual and same for seals leaking so I'd presume at times those might simply be laid off to age and miles ?
Thoughts ?
