The 1998-2000 Chevy Metro with 1.0L engine has an oil capacity of 3.5 quarts.
I have a 1998 Metro with the 1.3l and the Camshaft Position Sensor is located on the bottom of the oil pan.
5w30
Use 5W30
80w-90
Bottom of the engine on the oil pan.
5W30 in cold weather. 10W30 in hot weather.
99 Chevy Metro 1.0L motor holds 3.7 quarts. 99 Chevy Metro 1.3L holds 4 quarts. it is recommended when changing the oil to put in 3 quarts first, check oil level on dipstick, then add the difference to bring it up to the full level mark.
10w30 weight oil.
5W30 oil.
If I'm not mistaken you have to get underneath to change it. Should be a cap underneath it.
