Wusste doch, dass ich es noch irgendwo gelesen hatte:
Zitat
"Frequent oil changes with a visual inspection of the old oil (and the magnetic drain plug) will go a long way to serve as an early warning of brewing problems, and minimize the potential damage. Be SURE to use standard 30wt engine oil in the Ribcase transmission! 90 weight gear oil will result in rapid wear of the synchros."

Also war es doch nicht so falsch 20W50 zu verwenden ?
