homemade bike lube questions

So in a nutshell, Im mixing my motor oil (5w20) with mineral spirits... 3 parts spirits to 1 part oil.

Just got done applying it and I am concerned as it is quite a bitter thinner (viscousit-wise) than the traditional lube I use. Should I be worried that I am over-diluting it with MS? too thin of a motor oil?

Also, do you have to reapply every other ride or so if you are getting into wet weather? it doesnt seem to be as 'sticky' as the wet lube I use... although it doesnt seem to attract as much crap either.

3:1 is a good ratio and it is thinner because of the solvent... once that evaporates it will leave a nice coating of quality oil on and within the chain so after you wipe off the excess you should be good for a good while unless you encounter some really wet weather.

Re-lubing is dependent on mileage and the conditions you ride in so this is different for everyone.

I use a 50/50 mix with 30w as a soak. I let it drip off the excess and then blow with compressed air. So far so good. I live in South Florida and something as dilute as yours wouldn't hold up very well.

I've just tried this on my commuter. Drizzled a film of mixture (same proportion as yours...) and tried to hit the chain rollers.

I've only had it on one week, but it included a couple of rainy day rides. Seemed OK. No chain creak yet and no big mess of that mixture of oil and mud.

I'm just so sick of the mess using straight motor oil... even when you do manage to wipe most of it off.

For chain lube I use approximately 4 parts mineral spirits with 1 part 10 - 40w synthetic motor oil. I re-lube and wipe down the chain after approximately 200 miles.

Amen.... that sticky black muck no matter how much i wipe down after conventional stuff. So far, this thin stuff seems to leave a small film, and not collecting as much.

thanks for your routine, Al.... with the cheap stuff so abundant, squirting it on frequently seems to help flush a little better.



On a side note, if you flex your chain side to side, do you get some gritty noises/feeling coming out of the rollers/pins? I assume this is from the grit and gunk getting in there... Im hoping switching over is going to help flush everything better as well as prevent build-up

If you think you're getting too much git in the links consider a chain cleaning machine. They're better than they use to be. Also check your chain for wear "stretch".
