Question Is this a newer oil from Mobil One? 20W-50W

Mobil 1 V-Twin 20W-50

Mobil 1™ V-Twin 20W-50 synthetic motorcycle oil is formulated to help offer outstanding protection in 4-cycle, V-Twin type engines, particularly those which are air cooled and tend to run hotter than other types of engines.

Mobil 1 V-Twin 20W-50 motorcycle oil will help provide excellent performance in motorcycle engines that are designed with a common engine/transmission lubrication system or where the engine lubrication system is separate from the transmission system. In the case of the latter, follow the manufacturer's recommendation for the type of fluid to be used in the transmission. It is also designed to help provide the proper frictional characteristics necessary for wet-clutch engine/transmission systems.

I ask because I don't remember them having a 20w-50w, isn't this the weight that Victory uses?

Should be good to use: Optimized wet-clutch performance

I'm testing it right now and am happy with it so far. The best part is that it's available at WalMart and is about $6 per quart. I've ran 20W-50 in my bike since the 500 oil change and can't say anything bad about it. I should advise warming your bike up until the engine is warm to the touch in the winter (if you live in an area that freezes). My garage gets down to the low 50's and the bike starts slightly slower than in the summer. When I start the bike at work in the mid 20's to low 40's it starts much slower which is partially because of cold soak on the battery and partially from thickened oil. If the oil is thick enough to slow starting it's too thick to put a load on the engine until the engine is warm to touch.

If you live in a colder part of the world and ride in cold weather and are not using a 5wt or at least a 10wt multi-viscosity oil, you may be doing damage to your engine every time you start it. It's not just about letting the engine warm up (which is good) it is also about lubrication when starting the engine when it is very cold. A 5wt-40wt such as T-6 is better fitted for this than a 20wt-50wt, especially in a Victory with it's air/oil cooled engine... a 50wt really isn't needed in a Victory because of the oil flow thru the cooler then thru the cylinders then into the oil pan. 50wt was really develop for Harley's because they operate at higher temperatures due to their lack of oil cooled cylinders. Even here in Florida a 40wt is all that's needed for a Victory... but run a 50wt in a Harley for sure.

Thanks, you're correct, I'd looked it up earlier but had memory fail, I'll probably go with Mobil 1 Racing 4T 10W-40 or Amsoil.

I changed the oil at 500 miles with Mobil 1 V-Twin oil. I am almost to 2700 miles right now and I haven't noticed any issues.

The engine seems quieter to me than with the factory oil, probably because semi vs full OR break in oil vs changed oil. Not really sure.

All I know is Advance carries oil change specials on it, and if I can't get a Mobil 1 filter, then I go for a Wix filter available at Napa for $6.

My clutch does not slip, bike does not leak, engine does not overheat, and throttle hand does not let up.

Although I use Rotella T6 5W-40, in colder climes, I aim an electric heater at the lower part of the engine for about 1/2 hour prior to commencing a ride. That way the oil has gotten a bit warm for a safer start up. Its easier on the battery too. In winter, I keep an automatic charger hooked up to the battery to keep it from going into hibernation.

I have been using Rotella 5-40 for years. And just to see how it sounded in my xct I gave it a shot. At the time it was very hot and the bike shifted harshly and the roller rockers were even louder.

So I dumped that and tried 20-50 AMS OIL and I have to say the bike shifts much better and the roller rockers are much quieter.

BUT when the temperature drops I want Rotella T 5-40 or a 10-40 oil in the motor NOT 20-50
Remember 20-40 and 20-50 should be 20w oil at zero
The 50wt just protects better if the motor was to get REAL HOT....

The oil cooler does very little if there is no air flowing through it - like being stuck in traffic.......

Personaly if I am going to pay big bucks for oil it is going to be Full Synth
