Well i did my oil the other day, swapped out filter, drained every last bit out of engine, put the manufacturers oil type 05w 20, high performance oil filter, and 7 qrts of mobile 1 synthetic, just as ive read everywhere, not only is my car a lil more sluggish at excelleration but i checked my oil today and i have a cold reading of 1 qrt OVER the max?!WHAT THE $#!% I DRAINED oil correctly as ive always done, the drain bolt was at the lowest point of pan, was the 7 qrt a BONE DRY reading from the manufacturers? ? I dont get it but i will be draining at least a full qrt today and will only be putting 6 qrts into this car in future. First time ive had such a high reading by FOLLOWING the manual ?
