Rubbish!!!! You may not get maximum perceived benefits if you haven't used it all the engine's life, but you will most probably extend its serviceability. Additionally, if your point were true, don't you think the oil companies would have to put some kind of disclaimer on their oil - "Do not use unless Synthetic oil has been used from the very beginning!" No, of course not. Anyway, to use it from the beginning is probably not wise. Despite tight modern tolerances, new engines still need to be bedded in. The mineral oil placed in some engines is there deliberately - it's slightly inferior lubrication characteristics allowing the moving parts of a new engine to bed together properly. Synthetics are too good to allow this process to properly occur, and this can lead to glazing of cylinder bores etc (so I'm told). So, to cut to the quick, the maximum benefit of a Synthetic is probably achieved at the first oil change, after the bedding in period. Anybody got any input on this? Any mechanics who have seen the benefits/drawbacks of Synthetics/Mineral Oils?
