July 15, 2025Jul 15 I read a recommendation somewhere on t'internet that 90% EP90 gear oil mixed with 10% sewing machine oil is a good mix for bike chains. I thought I had some EP90 in the garage but only have 20w/50 mineral engine oil. I'm too much of a tightwad to buy both EP90 and sewing machine oil just to try it, but it would be interesting to hear from someone who has . The sewing machine oil apparently helps the mix to penetrate into the rollers but the gear oil is still thick enough not fing off all over the bike. That mix is near as damn it EP80! Go direct, much less fuss!

Wot Not paraffin wax and iirc ultra fine ground titanium oxide? Last time i browsed on the subject that was all the rage?

That was some guy's brilliant idea for thinning it down a bit. Unfortunately, he wasn't clever enough to figure out that he could have bought EP80 if he wanted thinner oil, but the whole point of 90 grade is that it sticks to the chain because it's viscous.
July 16, 2025Jul 16 Its only the inside rollers(bushes) that should have any lube on them. If your chain is coated inc the outside, that attracts dirt, which sticks to it and creates a grinding paste (I know most here know this, but some may not)

July 16, 2025Jul 16 I suppose thats why i spend a tiny bit more on nickle plated. All my chains are the cheapest you can buy from Ebay. They usually last 5 years with just EP90. No need for expensive nickel. I'm not sure about my crank-drive bikes, but I'll soon be back on hub-motor again, so I won't need to worry about it.
July 18, 2025Jul 18 I don't know if it's actually any better, but KMC do a mid drive ebike chain I don't normally use Halfords, but with the sale price it seemed cheaper than anywhere else https://www.halfords.com/cycling/bike-parts/gears-drivetrain-and-cables/kmc-e10-e-bike-10-speed-chain-silver-122l-300486.html
