I don't think too much makes the difference but the grade viscosity and ambient temperature certainly does.
I've found that gear, heim, ball joints and contact machine surfaces are greatly affected by the weight/grade of lubrication and warm or cold weather.
A gent from the petrochemical engineering trade referred me to a simple test: Take your favorite (or not) 3/8" ratchet, remove the back and clean and re-add a HD grease. Keep the ratchet in the house over night and try spinning the square drive with your fingers - first thing in the morning...NO noticeable difference. Leave it outside (in the cold) overnight and do the same finger spin test. Holy Cow!! big difference in drag and difficult to turn with the same two fingers.
His test was simple enough but his point was: The most basic equipment as well as highly complex stationary and mobile machinery requires thought in relation to the grade of lubricants and outside elements like temperature, humidity etc.
The short answer LOL...is yeah, I can see how your steering is affected by that grease.
