Has anybody used the Valvoline Full Syn 10w-40 oil?

I am currently running Amsoil Metric and it is about that time to do an oil change.

My choices are: stick to Amsoil, Valvoline, or Castrol RS.

Thoughts?

Recommendations are more a personal thing I think, subject to the oil being a name brand, and meeting the manual specifications. Every time I change the oil I have to stop myself from taking a mouthful! Sure looks like good stuff.
I've got to get out more I think.

I use valvoline and castrol rs in my bikes. Both have worked great for me. Last time I bought it, it was on sale for $7 per quart at my local auto parts store.

Between valvoline and castrol which one would you choose?

Castrol. Only because it says racing on the bottle. lol. Seriously though both are great fossil fuel synthetic oils. Neither are the quality of the "real" synthetic oils like Motul 300v or Maxima extra 4 (both $16 per quart). If you race use the "real" synthetic oils. If not, regular synthetic oil will be just fine. Just change it to suit your riding style. For me, I do not commute on the zx10r. It is for track days and riding hard, only. So I change my oil every 1500 miles or 6 months. If I commuted on them I would double those figures.

There is no such thing as "car oil" and 90% of engine oils can be used in a motorcycle with a wet clutch as long as it falls within the recommended group. My bike calls for 10w40 in the manual but oils/information have changed and I now use 5w40 Rotella T6 as it's JASO MA. I'll most likely switch to 0w40 next year as it's even cheaper then T6 and become readily available.

You up in the oil fields in Fort McMurray and know something we don't lol? Even if what you say is true, I will continue to use motorcycle specific oil, especially in my 190 whp zx10 lol. Now if I had a cruiser or a honda grom, no big deal.

Motorcycle specific oil is just marketing as any oil that meets JASO-MA standard, even if its not marketed for motorcycles, is for use with wet clutches.

Its always a safe bet to get a motorcycle marketed oil but it is most certainly not a requirement.

For more information on oil and specifications you can read here: https://en.wikipedia.org/wiki/Motor_oil#Motorcycle_oil

I'm pretty darn close, lol. I live and breathe oil and was lucky enough to meet/talk with some of the techs and chemists who create this stuff so yes, I might know something some don't. This past summer I put 10,000km on my 186whp 10'r using Rotella with only positive results so how can you beat first hand experience over marketing/internet hype.

I was being facetious when I asked you that lol. In all honesty, I believe you. However, I will continue to use motorcycle specific oil just because it helps me sleep at night lol. I have been told the oil I use in my car can last to 15,000 miles, but I still change it every 7,500 miles. Maybe because I just like being out in the garage and away from the wife haha.

I know highway 881 and 63 are treacherous during the winter and the only way to the oil fields. You ever travel over to BC and drive up the Coquihalla? I have been watching Highway Thru Hell on netflix. Crazy stuff from a person from Florida's perspective.

Piece of mind FTW! lol

Yep, I live on the border of AB/B.C and have driven pretty much every highway around here. The show makes those highways looks so scary and dangerous but in reality they are just like any winter highway. The scary stuff is when you're 2h in the bush, engine braking down one lane 45* grade mountain roads with 1000ft drops with no guard rails.
