How long does it take Biodiesel to erode rubber parts to the point of needing replacement?
The length of time it takes rubber exposed to Biodiesel to deteriorate is variable. The higher the percentage of Biodiesel you are using, the faster the rubber will deteriorate. Using 100 % Biodiesel (B100) will cause rubber parts to deteriorate significantly faster than using a 5% Biodiesel blend (B5). It is likely that you would need to replace your rubber parts before going 100,000 miles/160,000 kilometers if you were using B100 only.
