I have used T9 for the past 15 years on all of my drive train parts. The paraffin base helps keep dust from adhering to the chain which makes it easy to wipe off the chain after each ride.
I've tried a few different lubricants for my chains over the years, all of which worked fairly well. However, I have found T-9 to be the best one for my use, which consists of road riding for fun and for commuting. I don't encounter all that much dirt and gravel along my routes, but I still find that my chains can accumulate a lot of gunk quickly. What makes T-9 more effective is that it doesn't seem to attract dirt nearly as much and my chains stay running smoothly. As my headline suggests, I'm familiar with some of Boeing's other product offerings, and I always find them to be carefully engineered and the best of their kind. Enthusiastically recommended.
I lubricate my chain with T9, but I do this every 150 miles or so. In the past, I used Dumonde Tech chain lube, but my chain got filthy after just a couple of rides. I prefer T9, but I need to apply this more often. It doesn't attract road grime the way Dumonde Tech does.
Used this stuff for 15 years. My go to. Tried others but just come back to this oil. Best for my needs. I do keep a dry lube around for some parts work but for the chain I mainly just use this oil.
In 4 decades of serious cycling I've used an array of chain lubes. Boeshield T9 is works the best for me.
I got onto it abut 15yrs ago after always noticing how clean my buddy's drivetrain was whenever I was on his wheel. When I asked him about it, he said, "T9, man. It lubes great and doesn't get black goo all over like Tri-Flow"
i was tiring of constantly cleaning my chain with a plastic chain cleaning box and the mess it made. So I started using T9 and and never looked back. Now I NEVER clean my chain and my drivetrain components last
longer than they ever did before ! Reason being this stuff doesn't attract dirt easily. You simply put a drop on each link roller, then run your chain through a rag. You clean and lube the chain all in one swipe.
Because it has a slight wax base, you do get a little build-up on your cassette after many miles. But it sort of crumbles off easily by running an old spoke between the gears.
Quiet, clean drivetrain. Low maintenance. Long component life.........I like it !
I have been using the T-9 chain oil for the last 15 years. I apply it, let it soak, then wipe off the excess with a rag, then wipe it again after a ride. Frequency depends on my ride schedule, but wiping the chain after each ride keeps the chain clean and shiny ... I never have to do a heavy/detailed cleaning.
Been riding for 40 years ,raced for 20 ,keeping it fun 74 averaging 150 or so miles a week
I'm getting crazy miles out of dur ace chains with T 9 6000 miles
oiling every 100 120 miles
My LBS recommended this lubricant for my chain and I'm glad he did. I've tried another brand of lubricant, but found that I had to clean the chain way too often as it got dirty pretty quickly. This product keeps the chain clean and squeaky free. Other rides ask how I keep my chain and cassette always looking new, they think I sneakingly polish those parts while they aren't looking. I am anal about keeping the chain and cassette (or as I sometimes refer to as sprockets) clean as I don't like them dirty and I don't like having to replace parts unnecessarily . It's easy to apply, After cleaning the chain with the Parks chain cleaner tool, I spin the chain backward slowly while adding a drop to each link, let it set a few hours and wipe the chain to remove any excess. The lubricant lasts a long time since you aren't cleaning and lubing all the time.
I only use this lube on my chain, use the other lubes i tried on all the other drive train parts. I like the way it applies, stays on and cleans up, most of all a quiet chain. Ia'm a fanatic about a clean, quiet chain, wipe chain, put this on each link, wipe next day, wipe down after every ride.
Loud, does not last long (e.g. I have to reapply every 100 miles) and even when fully saturated, it does not work as well as Chain-L, Prolink Gold or Clean Ride.
Stay away. What's good for airplanes (Boeing) is not good for a chain.
