Umm, your method of lubrication (marinading - I love it
) sounds like you might end up with a fair bit of excess lube on the plates etc once you're finished. I ride every day in Scotland, where the weather is often foul, and the local authority seems to have a research budget of €millions to seek out the most corrosive road anti-freeze chemicals known to man... My chains last longest if I apply a little, light-weight lube (I use Finish Line 'Dry' - expensive, but good...) to them, on a regular basis - I 'deep clean' the chain with a chain-bath and citrus solvent every 3 months or so, and get about 1,000 miles from a (SRAM) chain.
As I understand it, lube on the outside of the chain does absolutely no good (except protect from corrosion), it just attracts grit and dust, so be sure to wipe off as much as possible after you've lubed the chain.
