I had the oil changed in January by my local Ford dealer who has done service on my 2006 Ford gt. I just checked it since I rarely drive the car and noticed that the oil level was about 1 inch above the max line on the dip stick. I drove the car for about 20 minutes and checked the level within 1 minute as described in the owners manual. I also checked the level when cold and it was about the same level, maybe slightly lower but still about 1 inch above the max. Should I just siphon it down to the correct level when cold and then check it when hot ot should I go back the dealer. They will probably accuse me of adding oil like they normally try to get out of the accepting blame for the situation. Is there any problems with dip stick reading as I have described?
