@NYCV4S @VYRUS
Since Redline may not ship anymore 15w-50 until April....what are yalls thoughts on topping off with 20w-50 instead (adding for losses from samples and dump for inspections, usually 300-400mL worth)? Any issues mixing?

thanks,
JAG

I don’t recall Red Line Power Sport having 20w50. 20w60 is available, and there’s no problem mixing one Power Sport viscosity with another. Red Line does have 20w50 in their automotive lineup. It wouldn’t cause a disaster if you topped off with a small amount, I would stick with the Power Sport if possible. The 10w50 Power Sport is also available and one of the very best oils money can buy. Your ambient temperature is the determining factor for your choice of viscosity. Over 90F, and 20w60 is preferable.

You’ll be fine. It’s a little thicker on the cold start being a CST 40c of 143 compared to a 15w which is CST 40c of 139. Just be sure to warm her up before operation past 3k rpm .

This is for the redline 20/50 power sports correct?

Yeah they have 20/50 for powersports , it is the standard for American vtwin bikes . not much different than the 15/50 formula besides for a touch thicker cold flow viscosity

Yeah you’ll be fine. Like I said just be aware of the cold starting and make sure you warm her up without revs . It’s not much of a difference but it is there showing it being thicker . hot rating is no different. cst 100 shows the same values .

thank you both, you classy Devil's!

Going to be just like the shell stuff. Mobil 1 isn’t what it used to be and all have less than 800-900 ppm of ZDDP. It’s glorified garbage nowadays. find any oil analysis for any labeled Mobil 1 , besides their racing formula which isn’t EPA approved , you’ll see it’s got nothing much to it. People might be upset that Im saying this but it’s the truth .

NYCV4S is 100% correct. I’ll add a little more nuance to this subject. I can’t say how or why I have this information, or discuss the most incriminating details. I’m on a very short leash.
You may have noticed a Mobil One decal under the hood of a car or motorcycle you’ve owned. Many of the manufacturers brand name oils are made by Exxon Mobil. As compensation for recommending Mobil One, Exxon Mobil has contracts with the manufacturers and their dealers in which Exxon Mobil provides all of their oil pumping and storage equipment in the factories and dealerships. Exxon Mobil also pays for the storage and removal of their waste oil. In many cases Mobil One pays for all the oil going into the new engines on the assembly line. That Mobil One sticker does a lot of heavy lifting. All of this adds up to a lot of money. Ultimately someone has to pay for all of this free stuff. When Mr Customer buys a $15 quart of Mobil One or a house branded oil Exxon makes, half of that money goes to pay for the free stuff. In order to balance the books so to speak, this money comes from using cheaper chemicals in the oil. All of the money Mobil One pays for advertising and stickers on race cars has to come from somewhere. You really didn’t think there’s an Oil Fairy who pays for all the free stuff?
When you pay $15 for a quart of Mobil One, you actually bought a quart of $7.50 oil. You may have noticed that Red Line and some of the other “boutique” oils don’t spend much on the things Exxon Mobil does. When you pay $20 for a quart of Red Line or the other smaller brands, more of your money goes into the quality of the oil and not into the manufacture’s oil equipment. If you think Exxon Mobil doesn’t know how to make the oil just good enough to get through the warranty period, think again.

@VYRUS understood on that NDA man...your def walking the line, but i'm glad you are doing it! keep it classy!
