the oil expands alot..its 9 liter of oil.
The new engine i have do not have a dipstick. the oil should never be more then between min and max since its expanding when hot.
However the problem is the dipstick is lacking on never models. i recommend just adding 0,5 L only if the oil is at min,,,, or a mbac warning is issued with the amount then use that amount.
however my measurements are fuzzy....due to the oil takes a very long time to heat up....just becasue ur water temp says 84 inside the van the oil is not hot yet. it takes about 35km on a highway for it to heat up completly...
