Wow the price of motor oil is now starting to feel the oil crunch. Even Walmart's supertech oil is at $1.74 a quart. Which in my opinion is not as good a deal especially since the Mobil Clean 5000 dino oil over there is only $1.97. Well I've now used Rotella synthetic, supertech 10w-40 regular, castrol GTX, and mobil clean 5000. My opinion is that Rotella offers the best shift feel which doesn't fade over time, but my bike consumes more oil on that stuff upwards of 3/4 of the hash marks on the dipstick in 3000 miles between oil changes. Probably it has the thinnest base oils. Mobil clean offers the same smooth clutch feel and still doesn't fade also it consumes about 1/2 of the hash marks in 3000 miles this is now my oil of choice. GTX used to be even though it had worse clutch feel than even supertech, oil consumption is the least, almost none, which means it may be on the thicker end as far as oils go but it scares me because I saw some metallic particles in the oil when I drained it. Super tech is similar to mobil clean as far as performance but the shift feel isn't as smooth after about 1500-2000. For my uses I'm no longer going to put GTX in.
you talking about car motor oil? You do know moto oil has different stuff in it for the clutch and such, right?
i dont understand what this post is for? ???
Okay, minor threadjack here but scottpA_GS, where do you get that "huh?" face? It's not an option in my menu but it is a VERY useful expression!
Thanks! :thumb:

Wow I'm a big noob. Been riding my GS (1st bike) for about 2-3 weeks now and planned on doing an oil change soon. I didn't know there were motorcycle specific oils. What happens if you do use car motor oil?
Quote from: http://www.calsci.com/motorcycleinfo/Oils1.htmlI get a lot of email, "My buddy has 283,000 miles on his Yamazuki 867 Nintruder, and he's never used anything but 35¢ per quart grocery store oil changed every 48,000 miles." Here's the truth: modern Japanese engines are amazingly well engineered and can tolerate a surprising amount of abuse. However, putting automotive oils in your motorcycle and running them for more than 1500 miles is abuse. I abuse my motorcycle enough with the way I ride them without adding on the abuse of using cheap oil that will break down in 1500 miles.

Depends on the oil. The main point is not to use engine oils with any "friction modifiers". These modifiers will get into the clutch and can cause the plates to slip. Similarly, you don't want to use any slipperly additives, like Slick50.
Here is an example where "friction modifiers" caused the clutch to slip:

Penzoil motorcycle specific? or just regular old 10w-30?

You're getting there :)
Suzuki calls for 10w40, right on the dipstick. Use the cheapest stuff you want, so long as the aforementioned 'friction modifiers' or 'energy conservation' additives aren't involved. You have a 'wet' clutch which means it runs IN YOUR ENGINE OIL, and those two types of oil will make your clutch slip until your next oil change to the proper stuff.
Car oil is fine. Car oil is fine. One more time, cheap cheap cheap 10w40 car oil is FINE ! :D
while we're at it, 87 octane gas is just fine n dandy too ! if you have pinging on 87 octane, something is foobar'd and you need to find out what !

Yep, regular ol Penzoil 10w40... 10w30 is fine to... check your owners manual for the recommended weights -vs- air temp. But all in all, just like ohgood and the others said.. watch for the "friction modifiers" usually only found in synthetic oils :cheers:

"Friction Miodifiers" are found in all grades of oil, and stay away from 10W-30 as it typically labeled "energy conserving" on the back. Stick to 10W-40 or if its really hot 20W-50
I briefly tried 20w-50 and it did not feel right. I think with the newer models that have oil coolers the oil is too thick. Shifting was just too crunchy. I drained it immediately. But the friction modifier that's a clutch killer is molybdenum disulfide better known as moly.
