Hi All,
It's been a little while since we revisited this topic, and that came to mind this weekend when I mixed up a fresh batch of my blend of Phil Tenacious Oil and Tri-Flow and packed it in a little eyedrop bottle to tuck in my underseat bag for use on long day rides. I've found it handy to have chain lube on-board with me to quieten a noisy chain that started out silent, or to replenish lubricant after a rainstorm. For me, the Phil Oil is
reasonably tenacious, but it can fling off the chain's tight circuit 'round the derailleur's jockey pulley and it has poor
immediate penetrating ability due to its high viscosity (it is not so much thick as very sticky). In contrast, I like Tri-Flow's PTFE in suspension, and it penetrates well. I've been playing with a mix of the two, and think I now have it about right at 90% Phil Wood to 10% Tri-Flow. I apply a drop carefully to the inner run (gear side) of each link initially, and a very thin drizzle across the edges of the link plates thereafter, also on the inside run.
In some past experiments, I had good luck using Lucas Oil Stabilizer (
http://www.lucasoil.com/products/display_products.sd?catid=7&iid=25&loc=show ), an aftermarket "oil extender" that clung to my chain like grim death and held fast in wet weather. It is still viable for that use, but absolutely horrible in the dry because everything sticks to it. Retail outlets for the product here in the States usually have a little demonstrator model on the counter, consisting of two pairs of stacked gears with crank handles, each partially submerged in a reservoir of Lucas Oil Treatment on one side and plain motor oil on the other. A turn of the crank makes it clear the Lucas' greater viscosity allows it to be drawn up by the gears, transfer between the teeth, and fully coat all friction surfaces. It is a bit like Phil Tenacious Oil in that regard. It certainly kept my chain well-lubed, but when the rain stopped, the thing soon looked like a loose sweet in a coat pocket -- furry with the lint of everything it contacted.
In April 2011, Future Bike conducted a test of commonly available chain lubricants, including Oil of Rohloff, here:

The test was conducted by Rainer May, a German mechanical engineer and everyday cyclist. He cites Rohloff's extremely long "steeping time" (Ein Ziehzeit) or soak-in period ("...at least a few minutes"; even longer in cold weather due to greater viscosity than some of the competitors in the test, which he describes as "water-thin"). Of the three oils used in the test, Rohloff's came in third for elongation, but the author preferred it for ease-in-application. Methodologically, he concluded his use of a high-quality chain made differences in the lubes less apparent; a lower-quality chain would likely have manifested increased wear showing the differences in lube more clearly. Overall, rainy weather in his on-road tests revealed a greater diversity in lubricity (term commonly used to describe the ability of a compound to reduce friction between moving parts) than did lab tests; some lubricants were not water-resistant and were quickly washed away in real-world use. A final note: Finish Line Wax did surprisingly well in his tests, given it is so thin.
Bottom line: Stutho is right when he says,
Ask 10 different cycles you will probably get 10 different answers! The best lube depends on the conditions you are riding in and what your successes criteria is: minimum dirt; minimum service interval; maximum rust resistance, minimum cost etc.
Lab test results may be clear, but real-world conditions and a user's frequency and care in re-application are factors that really prevent objective comparisons.
Before closing, a question: Have any of you tried the Rohloff Lubmatic semi-automatic chain oiler? If so, how effective was it? It consisted of a chainstay-mounted oil reservoir and hose that delivered user-triggered, metered doses of oil to the chain via a specially grooved derailleur tension pulley. It is no longer offered by Rohloff, but was popular among mountain-bikers for a time, particularly in wet climates. Anyone have one for sale? For details, see:
