So as not to hijack another thread, I started a new one to help answer this question. My Haynes manual says to put in 5 quarts of oil in my Dauntless 225ci V6. The dipstick is marked as 4 quarts. One explanation is that the engine takes 4 quarts and the filter takes another. On the other hand, guys have been running 4 quarts of oil in their engine without any issues and the dipstick read full. So which is it? was there two versions of the Dauntless? I know that there were multiple dipstick lengths, but I thought that had to do with the tube length and not the engine capacity.
