這問題也是我很久以前...(恕刪)
市售版的和比賽的不是相同的吧?! 不是很確定
不過以800km就換油的人來說 repsol爽度超高阿 只是燒錢也燒很大就是了
所以退而求其次的話 ultra 4爽度也不錯 燒錢就普通...
說真的爽度的話 ultra 4還是優於mobil racing...
mobil racing勝在耐久...爽度略遜...
不過每用一次mobil 4可以抵ultra 1.5次 怎麼算還是比較划算的...
話說 我看了小老婆那邊的討論...
國外有人做個實驗 mobil racing 10w-40混合mobil 0w-40 比例1:1
弄出了個5w-40的混合油 用在保時捷上面 效果異常的好...
等我下一次換油就用這方式 試看看 到時候再發心得文上來...

發問 兩種機油0w...(恕刪)
當然嚴格的算法不是這樣的... 這只是一種描述給大家看比較容易的方式
這是國外研究出來的結果...

If adding oil additives isn't for you, alternatively you can use Mobil 1 MX4T or V-Twin, as these oils have significantly more additives. If you were to blend 50/50 regular Mobil 1 and the Mobil 1 V-Twin, you will end up with Zn and P in the 1400-1500ppm range, which is basically like a SJ or CI-4. Similarly, you can blend 50/50 Mobil 1 0w40 and Mobil 1 10w40 MX4T (4T Racing) giving you a good level of Zn and P, balanced detergency, and the proper viscosity for required by your 986 or 996 (and later) water-cooled Porsche. This way you are mixing two similarly formulated oils made by the same manufacturer and you are most likely to have predictable results, like we have seen previously when we tested 50/50 blends of Brad Penn 0w30 and 20w50 and then compared back to back with test results of running the 20w50 Brad Penn oils.
由此看來混合mobil 0w-40和mobil racing 4t 10w-40之後 可以提供更好的ZDDP值...
可以推斷(個人猜測):
1.具有更好的加速性
2.劣化速度增快
倘若之前MOBIL RACING可以使用1200KM(機車上) 有可能降至1000KM就劣化 不過爽度應該可以提升
剛好家裡還有這兩種的備貨 之後混合後再提供使用心得給各位參考...
