Still seeing folks use the wrong grease on press fit bottom brackets
Was helping a guy at the shop last Saturday swap his crankset. He had a tub of generic automotive grease he was about to slap on a new PF30. Told him that stuff can make the plastic cups slip or creak over time. I always use a thick waterproof marine grease or something made for press fit specifically. Anyone else run into problems from customers using the wrong lube on these?

Man I read a thing once where someone used lithium grease on a press fit bottom bracket and the cups basically slid right out a few weeks later. That stuff is way too slippery for plastic cups, it just doesn't hold up. People really need to just grab a tub of marine grease and save themselves the headache.

...and that's exactly what I always see, people grab whatever grease they got sitting in the garage and think it's all the same. Like, that generic automotive stuff is way too thin for press fit stuff, it'll just squeeze out and leave you with a creaky mess in six months. I've had guys argue with me that "grease is grease" and then come back three weeks later with their bottom bracket making noise. What kind of weird stuff have you seen people try to use, like chainsaw bar oil or something?

Yeah 'grease is grease' is my favorite, lol. I had a friend once who swore by using bacon grease on his bike chain because 'it's natural lubricant.' He said it smelled good and was cheap. Took him about a week to figure out why his chain was making this weird sticky grinding noise and attracting every bee in the neighborhood. Another guy I know used WD-40 on his seatpost because he thought all spray cans were basically the same thing. That was a fun extraction job. But honestly the weirdest I've seen was someone who put anti-seize compound on their pedal threads because it was 'slippery enough.' That stuff is basically metal paste, man.
