Only a someone who visits this site would notice this, I just did my oil change and filled up with the German elixer and noticed is had a strong "sulfer" smell (batch M08). The previous oil change I did with a batch from M06 which has a sweat pleasent smell (still not as good as the green stuff).
Any idea what additive change Castrol has done to change the smell?
