I had my oil changed at the dealership today (98 i4 accord) and I noticed that my receipt stated that only 4qts of oil was used (or that I was charged for 4 only). Normally, when I change my oil, I use 4.5qts. I'll check the dipstick again once I get a chance.

Anybody have similar experiences at the dealership? Do they only use 4qts and not 4.5qts?
