Any objective evidence that this stuff actually does anything beneficial?

Any objective evidence that this stuff actually does anything beneficial?

I don`t know but doubt it, like me some users find it smooths and quietens motors but purely subjective.

Makes me feel better to think it may also give some extra cold start protection on my vehicles which often stand unused for weeks.

Peace of mind is priceless

The old PTFE based engine oil additives used to give people peace of mind untill the engine siezed up, the PTFE used to clog up the oilways and cause oil starvation. that was the peace of mind (an almost silent engine for a while) they were- tried and tested- or meant to be.

IMO best to stick to normall OEM oil filter change, engine should still start after weeks of standing without additives....

Just my opinion!
