ya it may be hard to start in your igloo LMAO
most guys use 20w50 in their HD's , it may require a little more warm up
in the manual it shows what temp to what grade
by the way it looks like the pre's only 10w40 is recomended

Dont the manufactures designate a certain type of oil for the clearances in that particular engine? 20w-50 would be alot thicker of oil than 10-40. It might not lubricte the small passages of the engine as good as 10w-40 would.Last edited by waffenampt; 07-03-2009, 07:11 PM.

Why do you want to run 20W50, It's a little thick for spring and fall. I use Rotella 5W40 Synthetic. The 5 weight is great for the colder weather and the 40 weight is fine for the hotter months. Maybe if you lived in say, Florida or Arizona but not for our cold Quebec.Last edited by katman05; 07-03-2009, 08:39 PM.

In the summer, 20w50 will be fine, especially if the weather is hot.
You can also mix-n-match (say 1 liter of 20w50 and 3 liters of 10w40, or a 50-50 mix, etc.).
General rule of thumb goes like this:
If it would hurt your feet to walk barefoot across asphalt in the mid-afternoon sun, use 20w50, otherwise stick to a 10- or 15- basis oil.
Suzuki's own table for weights vs. temps:
14 - 104+ degrees F [-10 thru 40+ degrees C]: 20w50
+4 - 104+ degrees F [-15 thru 40+ degrees C]: 15w50
-4 - 104+ degrees F [-20 thru 40+ degrees C]: 10w40, 10w50
-4 - 86 [max!] degrees F [-20 thru 30 degrees max C]: 10w30

Oh and ditto the Rotella T synth. Great stuff.90% of motorcycle forum members do not have a service manual for their bike.

Maybe they think it means pooOriginally posted by soulless kaosbut personaly I dont see a point in a 1000 you can get the same power from a properly tuned 600 with less weight and better handeling.

I probably ought to eliminate 15w45, as the only oil that was rated that I think has been withdrawn/morphed into 15w50.

According to this chart...the Shell RotellaT 5w-40 synthetic shouldn't be used...?
API CJ-4 / SM (In the circle)
Also lists: CI-4 PLUS, CI-4, CH-4, CG-4, CF/SM
Is this the same RotellaT that everyone else is using with no problems?
