Yes and yes to those two questions. My garage floor is perfectly level. I let the car sit for 30 minutes which ten qts showed low, barely on the dip stick. I then let the car sit overnight and still got the same reading as before. This means either GM's golden rule of 10qts is complete foul or they need to get tighter specs in terms of their dip sticks in regards to where the proper oil level readings are gathered.
No other ifs, ands or buts about it. Going by the dip stick tells me my LT1 isn't properly filled with just 10qts.
