ok your not against what i said, is still dont find it coincidental that he has more then likely spun a bearing after a 0-180km run
Im sure when nissan did their tests on the RB26 it wasnt on an engine with 355rwhp,
the stock sump works fine for a stock car but when the engine is making more then 100hp over factory specs then reliablity starts to decrease and things do go wrong
anyway... i know of a few people that run 6L in their GTR's...GTRSEAN has figured it out that 6L is low enough to prevent the crank whipping through the oil in the sump
