Just canvassing opinion on what lube to use through winter. I've been using squirt for a few years now, and its great until the gritters come out. I find it just doesn't cut it when the road is salty, and the chain rusts pretty quickly. Especially when commuting as I don't have time to clean it at work. As a summer lube though, its fantastic and my chain has done 3500 miles with only 0.5 stretch. Now onto winter lube recommendations.
A mate of mine swears by gearbox oil, saying it does 50k miles in a car, so why wouldn't it be good on a bike. It is tempting as 1 litre is about £7, and this amount would probably last a lifetime. Anyone any experience of it, or any other lube recommendations? I've tried muc-off wet lubes, and the c3, but found they didn't last long either.
Thanks in advance
