Anyone use this oil? I can get it from work for about $70 a case (12qts). Im tired of getting raped for $60+ for an oil and filter with the harley syn 3. Im just not sure of this oil and wondering if anyone runs it and likes it?

 

ummmmm.......15w40?? Where in the primary?? I have run royal purple 20w50 in the bike with no issues..........

 

I also use the RP 20w50, does just fine

 

I use it in my 2006 HEMI Charger, 1981 Z28 Camaro and soon my 1995 Wide Glide.

 

The 15W-40 you are talking about is for Diesel pick-ups. Could be used for a big-rig if your pockets are deep enough. Not really Harley oil. Go with 20W-50.

 

I've run 15W-40 in my VTX without any issues....not sure I'd use it for a air cooled bike that specs 50

 

Excellent oil but I wouldn't run anyone's 15w40 in a Harley. Works great in my turbo car, though. Can you get the 20w50 for that price? That's way below retail.

BTW, I wouldn't use any RP in the primary since it has about 250mg of moly in the formula. Great for the engine, questionable for the clutch disks (very slick).

 

Im sorry guys, brain fart, i mean 20W50. Guess ill buy a case and give it a try. Thanks
