Synthetic-Mineral-Synthetic Swapping(합성유에서 광유,다시 광유에서 합성유로의 교체)

Synthetic-Mineral-Synthetic Swapping My wife took her 2001 Mercedes-Benz E320S 4Matic to a local shop to get its brake pads replaced. I suggested getting the oil changed between servicing as a precaution. However, despite the recommendation for synthetic oil, the local mechanic used dinosaur-derived (mineral) motor oil. Granted, he used the proper weight, however, it's not synthetic. I realize many folks have switched their cars from fossil oil to synthetic and that there are branded blends of fossil/synthetic, but I've never heard of switching from synthetic to fossil. Should I be concerned for either the long- or short-term? Should I have the shop replace the filter and all the oil with synthetic? This car is used daily as the family shuttle and  rarely gets to stretch out its legs Autobahn-style. And as you know, it gets pretty darn warm out this way during the summer. So I assume this qualifies for heavy-duty use.Alvin Lin Las Vegas, Nevada Clearly the shop made a mistake if they were instructed to fill with synthetic but used mineral oil. In that case they should change to the correct oil on their nickel. Mechanically, the mineral oil will not harm the engine in the short term, so you can change back to synthetic at your convenience. Mineral oils form more deposits than synthetics, and are less tolerant of high temperature, so it would be smart to change back to synthetic sooner rather than later, and in any case before the harsh desert heat takes its toll.

합성유들을 주로 취급하다보니 간혹 뚜껑에서 누유가 되는 제품들이 있습니다

묘하게도 국산들이 더 그렇습니다.....

여튼 이런 누유제품들은 판매가 어려워 제가 사용을 합니다

국산,미국산,유럽산,일본산,,,광유와 합성유

점도도 다 제각각이죠, 0w40,5w30,5w40,5w50...

한번 교환할때 제 차가 8리터가량의 엔진오일이 필요하구요

그러다 보면 8개의 서로 다른 오일을 혼용하여 사용합니다

제가 그런 혼용를 해야하는 이유는 팔지도 못하고 버릴수도 없어서죠 ㅋ

지금까지도 아무런 문제가 없습니다 당연한 결과죠...

결론~ 합성유에서 광유든... 광유에서 합성유든...오일의 바뀜은~~~~

아무 문제없다 입니다   끝~^^
