Question: Can Shell Gas With Nitrogen Shorten The Life Of A Cars Catalytic Converter,
Shell V power Premium gas has 5 times the government recommendations of gasoline additives, now including NITROGEN which Shell claims keeps engines cleaner. ALL grades of Shell gasoline now have this excessive additive. Nitrous oxide is removed by catalytic converters. What do you think about Shell gas, and other gas additives which claim to clean engines, but may have a negative impact on other parts of the car? Can Shell gas damage your car over the long run?
Best answer for Can Shell Gas With Nitrogen Shorten The Life Of A Cars Catalytic Converter
I’ve been looking for believable answers on this for many moons now and I am not coming up with anything. Shell is already a top tier brand, so the detergents the top tier certification were there before they introduced the nitrogen campaign.
Of course, most of the fuel/air charge in your cylinders is already nitrogen. Intake air outweighs the gasoline by 14 to 1, and 80% of the air is nitrogen. That is fine with the catalytic converter, which breaks the resultant NOx down into N2 and O2 anyway even if part of the gasoline can increase the nitrogen concentration in the exhaust from 74 to 75%.
To me it is a meaningless campaign. Shell is about the same in my books as other top tier brands. They make their comparisons against non-top tier gasolines, which tells me it is nothing all that special.
