Jag mailade MANN-FILTER och frågade men fick tyvärr inte så mycket nytt i svaret utöver att filtarna tydligen testas med M15!
Citat:
Thank you for your inquiry. Your question is not easy and unfortunately not clear to answer but I try my best.
We test our (normal) fuel filters with a mixture of 15% Methanol fraction. This is a more aggressive test fluid than the E10 fuel which is should be normally in use in Europe.
In general MANN-FILTER matches the OE quality. If there is an OE application which requires E85 we test our filter with E85 and make sure it withstand the fuel.
For cars or trucks which are “retrofitted” in the aftermarket to E85 usage we can not take liability for the use of our filters in general. The provider of the retrofit kit need to make sure the car equipment (not only the filter) is suitable.
Sorry that I can not give a black or with Information to you. It needs to be checked application by application.
In Brasil, were the usage of Flex Fuel is more common, we have implemented a particular “Flex Fuel” line in market but not over here in Europe (up to now).
Mit freundlichen Grüßen
