What’s all this $50 grease stuff, anyhow?

Car grease and oil get the job done for bicycle maintenance.

I used up my last mini-tub of Campagnolo grease about 30 years ago. Back then I think it cost a wallet-draining $15, but now it’s $50 for 100 ml! Is it worth it? Of course not.

I have a can of Valvoline grease I bought 30 years ago and it kept my Campagnolo hubs running smoothly all that time. Cost about $3. Those hubs are still as good as new. I repacked them only once a year.

So what is grease, anyway? It’s oil that’s held in a thickening agent, or emulsifier, usually soap. Now that’s weird. When shear forces come into play, the grease breaks down and releases its oil.

[I stopped using car oil. It’s too thick for today’s chains. Buy a bike chain lubricant.] As you might have guessed, I use car oil to lubricate my chain. I haven’t bought bike oil forever. Even if you don’t change your car oil, just go to a jiffy lube shop and ask for some empty containers, which always have a dab of oil inside.

Car oil may not be the best lubricant for delicate gears, such as a Sturmey-Archer hub, but other than that, it works as well as any specialty bike oil. I would not use WD-40. It contains solvents, kerosene and liquified petroleum gas that break down oil. It’s great for loosening rusty parts though.

    Wd 40 works well for cleaning the chain. Open Gear lube works great on a very wet day.
