2 Quick questions regarding chain adjustment

[Fazerider]

cant belive you have never adjusted your chain in 10 years...do you get someone else to do it ?....for a lubricant i always use chain lube....engine oil is just going to fly off and make a mess of the back wheel

Chain wear has more to do with mileage than age, but I'd agree with the Major that (new) engine oil works well. The slow drip from my Scottoiler means it's always lubricated and the old gritty stuff flings off. Sure some of it gets on the back wheel, but being oil rather than sticky goop it cleans off much easier than the chain lube I used to use. I typically get 40,000 miles from a chain since buying the oiler... it means it's paid for itself as well as making the bike easier to clean.
