Hey Jim, I've used the old formula and now the new. It wasn't front page news when DuPont changed the formula, and I wasn't even aware they did, till I did a little research before replying to the thread where you objected to Teflon as a chain lubricant. But regardless, both work well. I'm not so sure you will be happy with it though. I'm somewhat of a maintenance freak but not so much a clean freak. This lube will "collect gobs of gunky black tarry sludge" that Steve speaks of. For me it is no big deal. About every 1,000 miles I'll take an old rag and spin the chain through it several times, clean the derailleur wheels and throw the rag away. I never clean my chain. When I lubricate, I spin the chain and spray the aerosol from just behind the crank on the lower run far enough back to where the pedal won't hit the can as it rotates. Give it a few rotations, hit the derailleur wheels and pivots, brake pivots and WHALA ... done. Kinda messy and wasteful but a can lasts me a long time. I lube once a week or every couple hundred miles.
