Sorry, didn't mean to offend anyone by using the term "Cheap Gas". Unfortunately, even the more expensive gas may not have the appropriate additives. Gasoline quality is an issue few people think about. The formation of harmful deposits can be controlled by adding detergent-dispersants to gasoline, the most common of which is polybutene succinimide. Used with a petroleum carrier oil, detergent-dispersants help keep the intake manifold and ports clean. These chemicals are more effective than the carburetor detergents that were once used in gasoline, but they must be used at concentrations that are three to five times higher than the older carburetor detergents. At the "High" end of the fuel quality spectrum are "Top Tier" gasolines. These fuels are recognized by the vehicle manufacturers as having the most effective additives and in the highest concentrations. Gasoline retailers must meet the high Top Tier standards with all their grades of gasoline (not just premium) to be designed as a Top Tier supplier. In addition, all the gasoline outlets carrying the brand of approved gasoline must also meet the same standards. Gasoline retailers who are currently on the Top Tier list include Chevron, Chevron-Canada (B.C. only), Texaco (Chevron supplied only), Conoco, Entec Stations, Kwik Trip/Kwik Star, MFA Oil Company, Phillips, QuikTrip, Shell, The Somerset Refinery and 76. Unfortunately, fuel quality isn't something that is easily policed. Many states have programs in place to monitor fuel quality on either an ongoing basis or "incident specific" basis. Most are run by the state's "Department of Weights and Measures". Even so, the focus of most of these programs is to make sure consumers aren't being cheated at the pump and get the full gallon they pay for. Some programs also check fuels to make sure they do not contain too much alcohol. The specific density of gasoline can be field tested to determine its volatility and alcohol content. But testing octane and the amount and type of additives in the fuel requires expensive laboratory testing. So this type of quality testing is rarely done. Most gasoline refiners don't want to sell the public bad gas because they obviously want repeat customers. Even so, they also know that deposit formation is a gradual thing that occurs over time. So if they cut back on the additive package to save a few cents per gallon, nobody is the wiser -- and least not right away. The problem occurs when people buy the lowest priced LAC gas they can find every time they fill their tank. The low level of additives (or low quality additives) in the fuel will not be adequate to keep their engine clean, and sooner or later they'll start to experience driveability problems. Worse yet, if a bad batch of fuel leaves a refinery and ends up in people's vehicles, it can cause even more serious problems. There have been instances where too much residual sulfur in a bad batch of gasoline has caused a rash of fuel pump failures.

Not sure if this is the right place for this question or not. But, does anyone know how to remove the roof rack cross bars on a 08? I just picked up my 08 and tried to remove them and can't figure out how. I can move them back and forth, but not remove. Thanks Chuck |

They are really hard to get off or on. Mine didn't come with cross bars so the dealer ordered them for me and gave me a print out from the service manual on how to install them. You have to pry off the rear plastic covers on the roof rails and the the bars will slide in or out it you release the lock pins on the bars by lifting up the plastic tabs on the bars.Prying off the covers can break push tabs on the covers real easy or scratch the paint on the top of the car.I'd leave the cross bars on if I were you unless you really have to take them off. Maybe the dealer will do it for you, but probably not for free.

I have read all of the posts related to the musty smell. Mine seems to be coming from somewhere else. Checked the tire well in rear and it is dry as a bone and smells fine. I have a 2008 Equinox LT with 5,400 miles. Brought it in last week to my dealer complaining of a musty smell. It was rather bad and my wife could smell it on my clothes when I got in the house. The first attempt to remedy it was to coat evap coil. I was told something shorted out,(dealer would not expand after numerous questions) and they said they coated a evap coil per a service bulletin. Car was deodorized which was a terrible smell for a couple days. Smell is back and giving it back to the dealer to remedy. Has anyone had any other musty related smells coming from car besides previously discussed problems related?
