I don't actually have the car anymore. What I meant was: it would always start (all my GP's always worked), but when using the heavier-weight oil, it seemed the the starter was working really hard just to turn the motor. I'm sure the 20-something year old starter played into that, but once I switched to the lighter oil, it had no problem getting the engine spinning. Not nessesarily what you're getting at, but it does make starting much easier (when you don't have electrical access for a block heater).
