This topic gets beat to death and while I tried to search for something to confirm facts from myth I couldn't find a lot here. Just everybody putting in their thoughts with no proof behind it. So here is for everybody that wants to know if car oil is just as good as motorcycle oil. Kinda long read, but worth it IMO. Here it is: http://www.nightrider.com/biketech/oiltest1.htm

Summary: Car oil is just as good to use as motorcycle oil. motorcycle oil is all marketing.

 

valvoline makes oil that is cheaper then some car oils..........and if u use cheaper car oil...... u can see your self that it bubbles more........ ididnt read that novel of a link.......
but i rocked regular oil in my first bike and never had a problem......


good topic though

 

i run the valvoline car oil with tha red cap never had any problems
i think it's the 20w40

 

10 40 Motul..nothing else.

 

oil is oil. just no synthetic

 

vegtable oil....... hummmm

 

I'm not gonna explain the differences in engine oil cause everyone will be like - it's a stunt bike it doesn't matter.... which is pretty much true considering ppl here will swap a motor instead of changing plugs.

 

YOU CANT BE SERIOUS

 

there was a really good thread about this a while back explained from all points and views i would find that one for answers

 

right. i have a motor 42,000 on it lots of draggracing & stunting with it it was constantly on rev limiter, i used to ride highways wheelies at 13k rpm for ever too. only used honda gold synthetic still runs fine, stock clutch and it never had a valve adj. either
its stupid to try and save 10 bucks by using regular oil

 

+ 1000

 

Synthetic is fine so long as theres no Moly in it. The problem with car oil is this..... They put friction modifiers in it. Which is fine for a car when the motor ans trans are separate. Those modifiers will eat up your clutch. You'll have slipping issues and all kinds of other ****!

 

lots of people run full synthetic with no problems, it CAN cause a clutch to slip.

 

its cause its a Honda:YEAH not positive, but is the honda oil a semi synthetic? I run the yamalube 4-R (20-50 semi synth) works great, I even use yamaha oem filters.
