1. please state the official source that says Euro/Japan Mazda "recommend" synthetic oil for rx8, some random words from some guy on some forum does not really count.
2. the picture you googled shows "full synthetic for renesis", maybe it is a special synthetic oil designed for rotary engine and burns off without residue, i don't know. but it is not really the synthetic oil we are talking about in our context.
simple fact is: synthetic oil has higher burning point than dino, so it is harder to b

来自主题: Automobile版 - 还是换机油的问题
说换成synthetic容易漏的说法是针对老车,发动机密封老化了的,conventional
mineral oil里的矿物质可以保持gasket柔软提高密封性,而用synthetic可能会产生漏
油。
如果你的车没有那么老,没有关系,用一两次synthetic blend以后就可以直接上fully
synthetic,如果是好车的话就直接用Castrol Edge,贵不了几个钱,8,000-10,000换
一次。
5W-30低温流动性优于10W-30,应该是更理想的选择,另外US Specs的Castrol Edge就

VW does require synthetic oil for turbo engine. The cost of synthetic oil

yes.
full (pure) synthetic is the best choice for any car, old or new, turbo or

There is a concern that systhetic oil will cause the some old deposit to
come off since it cleans engine better, so the small pieces will cause more
problem or your piston ring will not seal well as before.
If your car had oil (non-synthetic) changed regularly, there is nothing to
