Chevron makes fine gas and techron is a fine additive. But it isn't noticeably better than any other brand of equal octane (in So Cal).
I can only speak for sure to this region, but it's so tightly regulated that even the additives are controlled and regulated as to how much, what kind, etc. There is very little difference in any gas brand if at all.
I have a bottle of techron in my garage, and every month or two I'll pour a couple ounces in the tank just for good measure.
I can't say it makes any difference but I have it so I might as well use it up.
I'd be more worried about betting OLD gas than which brand. if a station sells 1000 gallons a week I'd stay away.
If they sell 3000 gallons a day, you're more likely to get get good, fresh gas.
Today's reformulated gas looses (sp
) about an octane point or more per month 91 down to 90).
The longer it sits the weaker it gets and the more wax and varnish forms.
Also an underground tank that sits and doesn't do much volume has a higher chance of getting contaminated with water. On a good/bad scale, that'd be down at the bottom near the bad part.
I'd assume the gasoline in the PNW would be regulated just as tightly but that would just be a hunch.
