a small tank-town...had the big old-style bowsers
The "high test" gas (premium) was really red-colored. "Fill 'er up with red."
OK, so some of your terms (small-tank town & bowsers) are as foreign to me as some of the terms our friends from down-under post!
I never heard of the gas being dyed red (except for in the US where it indicates diesel that has not paid road-use taxes and is for non-commercial/off-road use).
I got a chuckle out of your use of "hi-test". That term comes out of my mouth instead of "premium" and my friends, who are older than me, give me ahard time about it. When I rented the BMW in Denver a few weeks ago, the guy told me to make sure to use "hi-test"! SO maybe I'm not out of time, I'm just using a term I picked up when we lived in the west?!
Anyway, thanks for sharing your memories!
