So obviously this a widely sparked debate:

Using car oil in motorcycles.

I personally see nothing wrong with this as long as it doesn't have that "energy saving" additive in it. If you look in our manuals it says nothing about having to use motorcycle oils. It simply says use oils that meet these certifications (can't think of them off the top of my head).

Obviously theres people that swear up down and backwards that motorcycle oil is the only way to go, especially since we have a wet clutch...well...where's the proof? Just seems like a big marketing ploy for the oil corporations to make a little extra money. Sure they SAY motorcycle oils are better but have they proved it?

Just curious what you guys think about this.

A LITTLE extra money? Dude... That shit is over 12$ a QUART!!
If I could use synthetic car oil SAFELY and I knew it... I'd be a much happier[and slightly richer] man.

Dude, you are a noob and an odor if ur gonna put car oil into ur motocycle. The rpm alone will burn the car oil up. Ur rpm red line at 6k ur moto redline at 15.5k... Just think about that when you're changing ur oil. Sure, u can use ur car oil... That's if u choose not to go over 60 mph.

Prove it.

technically speaking some hondas will rev to 12k, fully built motors. not that far off from what a liter bike does. and dont you think that say idk a bugatti veyron with 4 turbos and a w16's engine might not rev as high but sure as shit spins much more than any of our bikes. yet car oil

Oh and I forgot ... Ur car has transmission fluid... Ur bike don't...so if ur transmission were to... say... Get stuck in a gear and won't shift... We'll know why.

vuvo2002

Ok buddy, I'll go and f my bike up and take loads of pictures just for you. Okay? Hahaha.
Sorry man, just not feeling it...

Not saying you have to mess ur bike up, just asking you to give me some hard evidence to go on...is that so hard?

for me personally, its not necessarily about the "engine" aspect of it when it comes to oil... i know car oil will safely lubricate my bike engine. buuut we obvy have "wet clutch's" which is simply put, not something car oil is designed for..

car oil = engine.. not trans, and clutch.

some will say, oil is oil, and lubrication is lubrication...
and for the record. thats NOT what she said

Just do it and let us know what happens. It ain't going to stop me putting my usual motorcycle oil in mine as it's good stuff and I love my bike

the reason for it is that car oil does not have to put up with a gearbox. the gearbox in our bike's WILL break down the molecules in the car oil and render it useless after a short time. the gears literally cut's the car oil up.

why don't you run your bike on 5w30 mineral car oil and see how you get on!

as long as it's JASO/MA certified we're all good. there's plenty of people who swear by chevron's delo400. it's a diesel oil but supposedly really good for bikes n bikes with wet clutches. i mean 2 each his own but y spend double/triple the price for something that does reletively the same thing?? 3 quarts of mobil1 moto oil is like 30 bucks. where as 3 quarts of delo400 is like 12 bucks. now i havent used delo400 personally but i'm considering using it as i have friends that have n really like it.

^^^as above
and something to do with the way the oils heat up from cold of course
i know it sounds daft but would oil companys really work so hard on developing oils for different engines if they didnt have to.

(example ... mate done brakes on other lads car
threw away the small screw that holds the drum on and also the shims behind front brakes, "dont need them" he says ,
so why the hell did they develope them then ??).

but i see there is also a difference between a car mechanic and a bike mechanic
the bike mechanic is cleaner and more precise if anyone has ever noticed .

In theory:

Automotive oil won't stand up to the sheering force and compression between gears in the transmission. It will break down the friction plates in the clutch.

ZoomSplat

you DO need those shims.
