OEM’s are finally recognizing the need for additives and making such recommendations in their Owner’s Manuals. For years OEM’s shunned additives as they didn’t want to have to test the myriad of additives on the market and more importantly they didn’t want their cars to last longer than engineered for. And that’s the real reason they told their buyers not to use additives. Now they have a dilemma, as the oil companies have relaxed their standards for gasoline after the EPA reduced standards with the onslaught of the Katrina Hurricane that hurt refiners. Newspapers around the U.S. have been stating that the oil companies and their refineries have cut the detergency in gasoline by 50%. With this major cut in detergents gasoline is showing up at the pump with poor quality. The OEM’s vehicles are running poorly in many states so now the OEM’s think its okay to use additives.
For many years the OEM’s have stated DO NOT USE ADDITIVES in their Owner’s Manuals, until now!
Now starting with the 2007 Chevrolet Impala GM is recommending the use of fuel additives.
Additives: To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent engine and fuel system deposits from forming, allowing your emission control system to work properly. In most cases, you should not have to add anything to your fuel. However, some gasolines contain only minimum amount of additive required to meet U.S. Environmental Protection Agency regulations. To help keep fuel injectors and intake valves clean, or if your vehicle experiences problems due to dirty injectors or valves, look for gasoline that is advertised as TOP TIER Detergent Gasoline. Also, your GM dealer has additives that will help correct and prevent most deposit related problems. Gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area. General Motors recommends that you use these gasolines if they comply with the specifications described earlier. However, E85 (85% ethanol) and other fuels containing more than 10% ethanol must not be used in vehicles that were not designed for those fuels.
I find this pretty comical as they have been extremely determined, stating never use additives until now they have no choice as the fuel refiners are milking every cent of profit they can get and the OEM’s cars are running poorly. Well SFR has met Top Tier Gasoline with a one tank clean up for years now! Oh, did you catch the part that the GM dealers now have the proper additives at their service locations. This is just like the oil companies when they used to say don’t mix magnesium based motor oils with calcium based as they might not be compatible. Nonsense, and they abandoned that notion just like they abandoned their rhetoric when they said do not mix a synthetic with a petroleum based lubricant as they might not be compatible. Once the oil companies started selling synthetics they dropped that propaganda as where do you think synthetics come from? If you guessed petroleum base stocks you are correct. So they have to be compatible!
I guess you cannot blame the OEM’s and oil companies for protecting their interests but disseminating information that oil and fuel additives do not work and do not use them is false and they know it. It’s the additives that do the work not the base oil. Times are a changing and we have been telling you about the need for additives for over twenty years now.
