I have honda 500 cb 1994 and i want to know what oil schould use

I have a 2006 model and I have always used standard engine oil, that i got from asda (not the very cheap stuff)

there are various schools of thoughts on this subject, however I spoke to a person who works for a distributor who told me molecularity there are no fundamental differences in car and motorbike oil. Well apart from double the price

You can use any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate/year round. 20w-50 for warm climate/touring. Car oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier. Shell Rotella T ($12 a gallon ) and Rotella T Synthetic 15w-40 ($22 a gallon) are inexpensive JASO MA oils. In most Honda's you will need 4 quarts of oil, an aluminum drain plug washer, and a filter. Pour in 3.2 quarts , run the motor, and check the oil level . Top up as needed.
