Chevrolet Impala Bi-Fuel (CNG) Engine Oil Specs

The Chevrolet Impala Bi-Fuel (CNG) was produced from 2015 to 2016. This model typically uses 5W-30 full synthetic engine oil — a specification common to most Chevrolet Imp-series vehicles.

Selecting the correct oil viscosity for your Chevrolet Impala Bi-Fuel (CNG) is essential. Using a grade that is too thin reduces protection at operating temperature, while too thick an oil impairs cold-start flow and reduces fuel economy. Always match the exact grade shown for your specific model year.

The recommended oil change interval for the Chevrolet Impala Bi-Fuel (CNG) is every 7,500 miles or 12 months. Under severe driving conditions — track use, towing, or frequent cold starts — shorten this interval by 25–30%.

When servicing your Chevrolet Impala Bi-Fuel (CNG), always replace the oil filter at every oil change. Using a quality filter — such as ACDelco or Mobil 1 filters matching GM specifications — helps maintain optimal filtration.

Oil change costs for the Chevrolet Impala Bi-Fuel (CNG) at a US dealership or local service center typically range from $60 to $110 for a standard synthetic blend or full synthetic service. DIY oil changes cost approximately $30–$65 in parts (oil + filter) and take about 30 minutes with the right tools.

Always consult your vehicle's owner's manual to confirm the exact specification for your specific trim and engine variant, as some Chevrolet Impala Bi-Fuel (CNG) configurations may have different requirements.
