differance between bike oil and car oil

right did a oil change on the bike got the bike oil and filter not a problem

but when filling it up i notice its the same oil (ie 10w40) that i use in my car

now is there any differance at all??

The car one has friction reducers which Bikes wet clutches dont like.

cool no probs then lol, was asking as i can get the 10w40 oil at trade for like 10 pounds but the bike oil i cant

Some bikes don't like being fed on a diet of Fully Synth oil too - Aprilia's 1000cc V-twins are one of them. It causes the clutches to slip

Best keep with motorcycle oil.

What about olive oil? healthy and might help the SV loose weight

Cars oil doesn't serve as gearbox oils as well which really chows it up.

Depends on the oil, the actual additives which help the oil withstand gearbox pressures can be found in car oil just very slightly less of it.

The answer is a massive "it depends" because there's feckin thousands of factors to consider. Some engines will take cheap crap car oil, some car oils are pretty similar to bike oil anyway, some are totally different.

People say lots of things about gearboxes chopping oil up, "friction modifiers" and have no real idea how that applies to the oil, and the motor in question.

However, the only way to guarantee good service from a motor is to use the oil it was designed to use. For the SV thats a 10w40, API SF/SG.

P.s you won't find many bike oils meeting API SF/SG
The motul 5100 I use far exceeds that standard as it's a 100% ester synthetic, but it's not TECHNICALLY correct for the bike as it's JASO MA certified NOT API SF.

See what I mean about it being a grey area?

Not again.
