Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

Engine is consuming over a quart of oil approx. Every 1800-2000 miles. I was shown a bulletin that said that there was a problem with oil consumption at the dealership. I brought the car in twice to them each time the low oil light came on and each time they told me there was nothing that could be done but to check it every day or two and keep track then come in with my notes to see what was happening. I brought the car to my regular garage the next time the oil was low and 4 mechanics informed me that the rate of oil consumption was not regular and that there is a problem if it is not making it passed 2000 miles before it loses over a quart of oil.
