Is it ok to use used motorcycle engine oil as chain lubricant?
Using engine oil as a chain lubricant might serve you the purpose. In the long run, it could pose you certain problems.
- Engine oil is more viscous when compared chain lube. Thus it will attract dirt. This will hamper your performance.
- Dirt accumulated will create abrasion which will wear out the chain.
- Engine oil could get greasy at lower temperature or might even solidify.
- Improper lubrication would lead to chain wear, jerky transmission and added friction.
- Engine oil costs more than the chain lube. It is not economical to be using engine oil.
In the short run, using engine oil as chain lube might work but in the long run, this would seriously damage the chain.
Usage of engine oil or grease is not at all recommended over a proper chain lubricant. Grease wont penetrate into the O rings and X rings as compared to chain lubricant. Whereas engine oil lasts only for a few days which reduces the life of your chain and sprocket.

You shouldn't use motorcycle oil as chain lubricant because it will-
1. Sling off the chain as it it made to film off of parts and be pumped though a filter and back into engine parts.
2. Attract dirt. Another property that those good petroleum engineers did was make a product that carries the contaminants to the filter. Bikes don't of course have that filter so the gritty material will wear your chain and gears.
3. It is wash out resistant. Good for resisting rain, but it resists mild chain cleaners too. Oh, you can cut it, but usually to remove it all you need a solvent not detergent.
Pl use only in case of emergency. Used engine oil without filtration will have lot of chips and dirt which will damage the chain and sprocket.
It is not viscous and sticky as say a ‘MOTUL' chain lube. Don't cut corners based on some amateur's advise. It is a matter of safety.
Its o.k if you spray over it with chainwax coz it seals the oil in, but if you're using old oil as opposed to proper chain lube then you're not likely to shell out for chain wax.
