Question

is it ok to put car engine oil to a motorcycle?

Answer 1

That depends on the motor. If it is a 4 stroke motor you should be alright but if it is a 2 stroke motor than you need special 2 stroke oil. This is because in a 2 stroke the oil gets mixed in with the gas. Some bikes automatically mix it for you but all 2 strokes have it mixed.

Answer 2

depends some on the motorcycle and some on the oil. NOT good to put newer 'low friction' reduced emissions car oil in a cycle with a wet clutch like many are- the low friction additives caused clutch slippage, high wear. On the other hand is the older oil formula 10-40 spec oils that Honda recommended for years in their wet clutch unitary tranny engine designs. Safer to use the CD 15-40 diesel oil at $16.00 gallon or 5 quart bottles- that oil still has zinc additives for good gear wear, no clutch hurting 'slippery' additives- I use it in Goldwing and CM400. BMW and Guzzi dry clutch, separate transmission designs can handle the newer oils OK as long as it is right weight. Actual motorcycle and actual oil contemplated clarified.

Answer 3

I would have thought by the second or third quart you would have noticed the bottle labeling.... Anyway, you did your car a big favor, but the downside is you used up some of your bike oil stock. Its getting hot outside anyway, and the extra protection the 10-40 provides never hurts. Just don't go trading off and use up your automotive oil on your bike when its time for a change as the oil designed for automotive use will not offer the shear protection in your bike as previously described...

Answer 4

You can't just use any car oil in a motorcycle.

Look at the back of the bottle. There will be circles that look like a target, if it says "energy conserving" put it back. There are friction modifiers in "energy conserving"oil that will make the clutch on your bike slip and fail.

I've been using car oil in my bikes for many years and miles without a problem.

Answer 5

It's better than no oil. ,but considering motorcycle engines reach much higher temperatures, You might consider making an effort to get the right oil.

Answer 6

if u ask a bike shop...they would say no cuz of the clutch that share engine oil. A car transmission is a separate unit so oil might be different.

Answer 7

its best to run what the bike specs. say in owners manual. also dont run a synthetic oil, will cause clutches to slip.

Answer 8

Sure, but I always used synthetic in my bike, whereas I don't in my cars.

Answer 9

yes if they are in same level of thickness as 10-30w.
