Gas and Flex Fuel (E85) Chevrolet maintenance
Many Chevrolet models use gas engines, including Flex Fuel variants that can run on E85. Stay on top of oil and filter changes, because short-trip use, towing, and dusty conditions can shorten oil life even when the oil-life monitor is fitted. Typical oil-change scheduling spans about 5000 to 15000 km or 3 to 12 months depending on engine and duty cycle. Regularly check air-intake hoses, PCV plumbing, and spark plugs/ignition components, since misfires can quickly damage the catalytic converter.
