Thanks for those revealing pics, bud. At long last I think I understand why my W123 would never maintain autobahn speeds with a half-tank of gas.

Good road,

So how does a fuel tank get into this condition? I'm guessing long term storage with a near-empty or empty tank.

That W123 I owned in Germany that I'm guessing had a rusty tank had been stored in a dry garage for at least a year before I bought it. But the body was pretty much rust free for a 20-year old Germany-driven car. I'd like to know how to avoid this happening to my R107 that isn't driven 4-5 months out of the year.

Do those gas additives really disperse any water droplets that condense and settle to the bottom of the tank? Which are better, the alcohol-based ones (like HEET) or petroleum-based variety (like STP, Techron, etc.)?

Good road,
