Best oil to use?

[Jethro]

I use Castrol SynTec, mostly becasue they don't have that foil under the cap. Just open it and pour.

I hate that friggin foil!

How about 0W-40W Mobile 1 synthetic?

Been using it since august and I like it. Shifts great at 40 degrees and all that

Mobil 1 is good juice. I have used the 15-50 red cap stuff.

Makes no difference. Just change it before it gets dirty.

I am sure that this has been brought up before in other threads, but for those who may not be aware of it here is a report containing a scientific analysis of Motorcycle Oils vs. Automotive Oils. Although this report was issued in 1994, I feel that it is still valid. Automotive oil quality is constantly being improved, as may be seen if you download the API Motor Oil Guide 2004 PDF.

A large part of the motorcycle retailing industry relies on and exploits the vanity, fear, and gullibility of its customers/victims. They use the same BS advertising methodology that constantly surrounds us, seeking ways to separate us from our money. How about "Motorcycle Gas" or "Motorcycle Air"? "Motorcycle Wax"?

Any latest API category (SM) automotive oil of the viscosity recommended by the bike manufacturer is well suited for motorcycle use. This includes synthetics, which are contained to some degree even in lower priced products.

Most important is changing the oil within recommended guidelines or earlier.

Oh, and don't let the crusty old salts tell you fairy tales about leaks caused by switching between synthetics and mineral oils. These tall tales had a grain of truth back in the '70s when synthetic oils first appeared, but they have no relevance now. If your bike springs a leak after switching to synthetic, it is a concidence that had nothing to do with the oil.

Man am I glad to hear someone else say that for a change. its amazing how many people in the automotive and motorcycle business spout that stuff.

I personally use honda 10w40 dino oil, 3.29 a quart, I do believe that automotive oil could POTENTIALLY damage your clutch pack,depending on the friction fighters that are added. I do know a number of people that use standard car oil without problems though.

BEST OIL TO USE

I PREFER TO USE AMSOIL SYNTEC 20-50
NO PROBLEMS RUNS FINE IF NOT BETTER
.OLDEST SYNTHECIC ON THE MARKET

[toymechanic.]

I knew a guy that used to use wesson vegatable oil in his 2 cycle Husquavarna, he never had engine failure. No Joke!! It smelled like potatoes cooking!

[BigMattyD]

Since I, too, am a pervert, I just filled my cycle with Walmart 10W40, from the "Big Jug." It's cheap, and it is only going to sit there over the winter.

I think that if you change your oil frequently, any brand will do. If you're into extended chahge intervals, or run an engine to extremes, go with synthetic.

i have a gs850 and i used car 10w-40 and it did not work with the wet clutch.
the clutch did nothing but slip. As soon as i changed the oil back to Suzuki oil the problem went away. I asked a 30 year MC machanic and he said "was synthetic oil around when your bike was produced" of course it was not.

does anyone out there own a 2 cycle MC? if so do you mix regular motor oil with gas or do you mix 2 cycle oil with the gas.

Suck it up and put MC oil in MC's and car oil in cars.

Sorry, but the 30 year mechanic is wrong. Mobil 1 was introduced in 1974. See
