Can regular gas ruin a turbocharged engine? Many motorists blow off automakers' "premium recommended" or premium required" warnings, but some 2010 Cadillac SRX owners are wishing they'd pumped the more expensive grade.
Cadillac has recalled 2010 Cadillac SRXs with the optional turbocharged V-6 after some customers ruined their engines using regular. So far, 547 vehicles are affected by the recall.
Both the manual and a warning on the fuel-filler door told drivers that "premium fuel is required" for the 300-horsepower, 2.8-liter V-6, according to Cadillac. Typically with engines needing premium, automakers program the electronic control module to adjust -- with a loss of full power output -- to protect the engine if a driver is unaware or attempts to cut costs and fills up with regular.
