Oil Filter - Carburetion & Turbo Systems Vortec 5700 Operation And Maintenance Manual

(Changing Engine Oil and Filter continued)
Under abnormal operating conditions, the oil and filter should be changed more often if the
engine is operating in dusty or extremely dirty areas, or during cold weather. No oil additives or
break-in oil change is required.
ENGINE OIL QUALITY
To achieve proper engine performance and durability, it is important that you use only engine
lubricating oils of the correct quality in your engine. Proper quality oils also provide maximum
efficiency for crankcase ventilation systems, which reduces pollution.
Important: Use only engine oils displaying the American Petroleum Institute (API)
"Starburst" certification marked "FOR GASOLINE ENGINES" on the container.
Gasoline engines that are converted for LPG or NG fuels MUST use oils labeled "FOR
GASOLINE ENGINES" also. Do not use oils that are specifically formulated for Diesel
Engines only. CC or CD classification oils, even when labeled Heavy Duty or for Natural
Gas Engines ARE NOT ACCEPTABLE.
ENGINE OIL RECOMMENDATIONS
Multi-viscosity oils are recommended. SAE 10W-30 is recommended for your engine from 0
degrees F (-1 8 degrees C) or above. If ambient temperatures are consistently below 0 degrees F,
SAE 5W-30 oil can be used. Synthetic oils are not recommended for industrial or stationary
engines.
OIL FILTER
The engines use an AC Delco oil filter as original equipment. An equivalent oil filter must be
used when servicing the engine. Below is a chart showing the correct oil filter for your engine:
The filter protects your engine from harmful, abrasive, or sludgy particles without blocking the
flow of oil to vital engine parts.

OilFilter
To replace the filter, use a proper oil filter wrench to remove the filter. Clean the filter-
mounting base and lightly coat the gasket surface of the new filter with engine oil. Hand tighten
the filter until the gasket contacts the base, then tighten another '/2 turn. Fill the engine with the
correct amount of oil, run the engine and check for oil leaks at the drain plug and oil filter gasket.
Tighten as necessary to stop any oil leakage noted.
