Which oil is more suitable for chain lubrication?

I'd go with a spray synthetic motorcycle chain lubricant (Silkolene or Bel-Ray). Most brands are pretty good. With use, you'll find out which one works best in your application. Place the bike on its stand, rotate the rear wheel forwards, and spray the chain and rollers.

My bike bajaj discover 100cc when running that time speed cut in between what to do and not running more than 60km/hr and mileage giving 65km
Tell me why this problem?

. Replace the spark plugs with the same plugs that came in the bike. Bikes are hard on plugs.

. Change the oil frequently, for long engine life and top performance.

. Change the air filter regularly--dirty air filters can dramatically affect performance and gas mileage.

You should get around 80kmpl.

Common man, you can't get better than 65kmpl in city, I hardly get 55kmpl. It also depends on how you ride etc
I drive more than 3kms in first gear in bumper to bumper traffic in city everyday!

I also own Disocver 100cc Dts-si 2009 model
