50 straight weight miracle : V-Twin Forum: Harley Davidson Forums

laugh all you want but I have found the quietest oil yet. Valvoline dyno straight 50 wt. yep I have tried them all in the last 4 years and 70,000 miles and if I had not heard it I would dismiss it, but it is oh so quiet that I had to post even tho I was reluctant. oil temps have stayed the same, mpg the same, everything the same but no more tick tick tick. amsoil, mobil 1 20-50, rotella (a distant 2nd quiest) harley 20-50 syn and dyno etc.

I'm having good luck running lithium grease in my bike in the summer and STP in the winter. JUST JOKING. Where do you find SAE 50? I think I've read some dudes saying they run straight 60 or something. Some would argue that your top-end doesn't get lubricated quickly enough. I don't know enough to verify that. Would SAE 50 be OK for your Montana autumns when it's quite cold overnight, or would you have to switch back to 20W50? My understanding of the multigrade oils is that the upper number indicates that the oil performs the same (has same viscosity) as a straight oil of that number at operating temperature. Obviously a hot SAE 50 flows better than a cold SAE 50. I wonder if it's close to a cold 10 or 20 weight when it's at operating temperature.

And let the Debate begin!!!

Pretty bike you have. However, I can tell by looking at you're running the WRONG oil. Don't be surprised if that thing seizes up because you didn't spend enough on oil. :P

Damn, how could you tell!!!!!!!!!!! I have been running staight weight cooking oil...ROR

jrmcc999 · 05-31-2009, 01:30 AM

Pure soybean oil or that evil hydrogenated Crisco? They don't allow that in California . . .

Out of stock at the moment, OH, not Valvoline either before you correct me but I am sure Google would give you a hit on that brand - AMAZON OF ALL PLACES

I got it at a Quest Auto store they also had 60weight. I will go back to 15-40 Rotella for the winter but for now it sure sounds good. My wife who did not know I even changed oil and has a great music ear but no mechanical awarness at all even commented that the bike sure sounded good after our last ride. anyway don't want to create a debate but just pass what my experience was. If you have tried different things to get rid of the tick go spend $12 bucks on some cheap 50 weigh, don't even change the filter, if it works it was a cheap fix if not you are out $12 and change back to your favorite beverage.

thanks mtclassic. i ran straight 50 and 60 last summer to experiment with the front exhaust tick, i will try that valvoline as soon as i get broke in.

to the others, try peanut oil, you can maintain 350 degrees for hours.

I tried that too, but the grass hoppers kept following me around.

I am guessing if another brand of 50 wgt did not do it for you Valvoline probably won't either, I did note that the 60 wieght said right on the bottle extra zinc added. VR1 is what is.
