omegaman,
Don't toss that out! Chevron makes a quality additive so it's fine to put in your tank. Redline makes their brand SL-1 is a good additive too so both will be good for the gas you use.
Sometimes I buy COSTCO gas and every other month I toss in a big bottle of Techron or redline to suppliment the additives in the gasoline cuz people have said discount gas has less detergent than the branded gasolines.
