This is what I sometimes run during the hot summer months here in the lower midwest, where temperatures of 100+ are fairly common...

Other times I run Mobil 1 15W50 in the engine.

 

Thanks for all the responses!!!

Unfortunately, I need to get these fluids changed ASAP and don't have the time to wait for any exotics to be shipped. Thus said, my choices for the remainder of the Minnesota riding season are a bit limited to what I can obtain locally or within a day or two... And NO... Express overhight shipping is NOT an option for this kid's wallet.

I have my choices of anything at the local H-D dealer or auto parts store. I do have a NAPA within striking distance but not sure what they carry as far as motorcycle lubricants. Within a day or two, being close to Dennis Kirk, basically anything by Spectro, Maxima, Bel Ray or Royal Purple.

I'll have to wait until next season and my "new" 95 inch engine to try the exotics...

So... out of the sources I listed... Which would you choose? Keep in mind, I only have a projected 1000 miles left this year and would like to quiet down the engine/drive train noise if possible...

Thanks again!!

 

Walmart - 5 quart jug of Mobil-1 15w-50 ~$23.00
Autozone - 1 quart Mobil-1 75-90 Gear Oil ~ $9.95

 

You can get Mobil 1 15W50 at 'WallyWorld', NAPA, or a million other places. Cost about $4.25 a quart when purchased in the 5-quart containers.

The majority of guys I know with very high mileage bikes run it year around.

Other guys I know that like conventional oil run Castrol GTX 20w50 all the time.

Rotella T 15W40 for the primary can be purchased anywhere as well, at about $2.75 a quart. I've used a lot of different primary fluids in Harleys over the past 39 or so years, and since I started using the Rotella T I won't run anything else.

In the tranny any fluid with a API GL-5 rating will be just fine.

 

All three dealer near home quit recomending sy3 in tranny and primary last yr..
all 3 are using formula+ in primary and 2 in the tranny, 1 is using bel-ray in tranny, and what ever U like in the motor.. each one carries different brands of motor oil.
