Fred2 wroteMost people ask for there brand of oil and any left over goes to the customer.
Used oil and oil filters are soled, oil is mix with diesel to power generators and boats. oil filter casing is used for metal crafts.
Markit your manual say 6000km for service, my new bike is as per honda book because its new. My old bikes are 1000kms and I change it myself with filter, I found out the yamaha dealer only replaces the filter if you ask.
What kind of oil is recommended for your bike Fred2? Is it a new bike or scooter? Synthetic?
