I stopped being picky about oil, once i read this article about a guy with a 1996 cbr 900 with 150 thousand miles and all he used was castrol GTX car oilat 2 bucks a quart, they are all good, as long as they meet what your owners manual specs, if you are spending more than 10 bucks for some motul or belray crap you are an idiot in my not humble at all opinion. What do you really know about what yourbike likes as an oil, they are all good, by the time you move to your next bike the wear and tear is absolutely insignificant,There's nothing wrong with car oil for your bike.

 

What oil to use doesn't really matter a whole lot. Just make sure it is for wet clutch motorcycles. Change the oil and filter every 2,000 - 3,000 miles and the engine will outlast the rest of the bike, so long as the rider isn't abusing it.

 

... and fully synthetic oils out perform dino oils. That in a nuthshell is all there is to know of importance.

 

Crisco.

 

Buuuut most of the synthetic oils marked "full synthetic" are actually a very highly refined dino oil.

 

crisco heheh

I once told a friend of mine he could grease his bicycle bearing with Crisco. It lasted about an hour...

 

You can also get about 10 cans of WD40 and spray them fully inside your engine,I would recommend you use the little red straw for this procedure to be easier, and don't forget to check the level afterwards.

 

Respsol is what ive always used.....never had any problems...knock on WOOOD!

 

Definitely not a good decision. I have run many brands... Honda G4, amsoil, belray, motorex, maxima, and now I'm running a semi-synthetic Golden spectro 10/40.

on a couple times, when in a jam, I used car oil and it sucked *** for the clutch and made the bike run hotter.

For my CBR1KF, 929, and 954, they like stock weight and semi sythetic. I won't buy full synthetic because I religiously change the oil at the first signs of it being dirty. My mowers, wheelers, etc.. all get good oil changes from the used oil.
