Oil threads come and go every year, I guess because people just can't understand that the cheapest oil out there actually works better than just about anything else on the market at any price.

I like the Rotella synthetic 5W-40 best in two of my bikes (they seem to run quieter with it than the standard Rotella). The standard Rotella 15W-40 is used in the other bikes, or Mobil Delvac 1300, whichever one is on sale (usually one of them can be scored for less than $15 per gallon). All three of them are heavy duty diesel oils with lots of zinc and phosperous, which is what any wet-clutch really wants to be fed.

Advance Auto parts also has a generic version of Rotella 15W-40, which is usually about $1-$2 less than the Rotella, and seems to be the same stuff. When it's on sale, it goes for about $12 per gallon.

If you use one of the oils listed here, you can rest easy knowing that you aren't wasting money, and any engine issues you might have aren't going to be oil-related.

Arggghhhhh !! Fifteen dollars a gallon ? I hate you !!! :mad:
 
Mobile Delvac is under 14 bucks every day at Wal-Mart, tho I hate to give them my money.

That's about what it runs here, $14-$15.

Sometimes Rural King will run a special on Rotella 15W-40 for $65 per five gallon pail. That's when I "stock up" and buy enough oil for the entire year.
 
Just picked up a gallon of Rotella for $12.75/gallon at Wallmart. Next time I'll go for the T6 synthetic. I think it was around $21 for a gallon at Wallmart. Running that in my 850 and it seems to love it. Engine much quieter and smoother shifting.
 
I picked up 4 liters of 10w/40 mineral oil today,I'm hoping that's going to stop the smoking exhaust that I picked up after i tried the modern semi synthetics.
 
I have never run a motorcycle specific oil in any of my bikes.

My GS has over 80K on the clocks, and 95% of it's lifetime in my hands (about 55,000 of those 80K miles) it has seen nothing but automotive M1 15w50. No clutch slippage.


My KLR650 has seen some M1 15w50, but thumpers are pretty hard on oil so I have used Mobil Delvac 1300 or Rotella T 15w40. 46,000+ on the Pig and still going strong. :)
 
I went cheap this year, I mean really cheap! I'd been using Royal P. in my bike for 3 years with a little trouble hitting 2nd gear and finding neutral. I went for 10w-40 Walmart oil...$10/gal after my wife's discount. It's easier to find neutral and 2nd gear is easier to hit to...Expensive isn't always best.
 
I used to run Rotella since I have several diesel vehicles in the yard, but now I've been going cheap. I buy Fleet Farm branded 10w/40 oil, generally runs about $1.99-2.40/qt, or $7.50 a gallon. I change oil in my bikes more often than my truck, the Suburban or the motor home.
 
From the current issue of Cycle World ("Service" column):

"...as long as the oil you choose is designed for motorcycle use. Motorcycle oils do not contain the friction modifiers found in automotive oil, which can cause slippage issues with a bike's clutch."

Whatever works. :)

I've been buying the Mystik in 4 gallon jugs for the motor home. 16 qts to do an oil change for it. I'll just have to check prices better next time I guess. :)
 
I use Rotella 15w-40 in all of mine. None of them complain. I buy it at Tractor Supply, since I won't step into Wal-Mart.
