MObil-1 V-Twin 20W-50


On sale here...stash up! More folks are using it as the "low zddp" concerns continue. Supply is low.

About $10/qt Ups'd to your door.

Hydro - any downside to Mobil-V twin? I am going to switch soon. Why do some still balk at using synthetics? There seems to be still a few holdouts.

For offshore engines you need:

-Excellent anti-corriosion additives (boats get stored for periods)

-Excellent Base stock (To resist heat)

-Excellent ZDDP levels ( long lasting protestion)

-Excellent resistance to shear down. (Running at high RPM and high load protection)

-Anti foaming additives (for when at long high RPM runs)

V-twin delivers all the above!

Going to synthetics has been increasing:

Why using a "motorcycle oil" makes sense now more than ever:

Motorcycle manufacturers have come up with a very clever way to avoid meeting the newer and more
stringent API standards while still selling their oils as premium "motorcycle-specific" lubricants. Most
motorcycle-specific oils haven't been tested for the latest API standards in the past decade or so. They
are still rated SF or SG, which, according to motorcycle manufacturers and dealers is better for your
bike. Many times they'll even go so far as to say that they'll void your warranty if you use an oil that is
SH or SJ rated.

Zinc and phosphorus are actually almost always added to an oil in combination and in closely related
amounts. They work as a tag team to help minimize wear due to metal-to-metal contact. In essence, if
there is ever a time when your engine components are under significant stress and the oil can't
maintain a film of lubricity between metal components, metal to metal contact will occur.
Under these conditions, without some extra measure of protection, this would cause severe wear within
your engine. However, the addition of zinc and phosphorus to your oil minimizes this risk. The zinc and
phosphorus will actually form a thin "plating" over engine components preventing actual metal to metal
contact - thereby preventing metal to metal wear. This is a VERY good thing, and very desirable.
Keep in mind a couple of things, though. First of all, the amount of zinc and phosphorus in your oil does
not determine "how well" your engine will be protected against metal to metal contact. More zinc and
phosphorus does not mean better protection. However, it does mean "longer" protection. The more zinc
and phosphorus you have in your motor oil, the more times it will be able to prevent engine wear from
metal to metal contact.


With that said, let's move on to the fallacy of the argument against SH and SJ oils for motorcycle use.
First, it must be understood that most motorcycle applications call for a 10W-40 or 20W-50 viscosity
grade, especially for larger engines and V- twin applications. So, in determining whether you can safely
use an automotive oil in your motorcycle engine, only those two grades really need to be considered (or
some similar grade like 20W-40 or 15W-50).


So, here's the deal. API SH and SJ specifications have indeed lowered the maximum acceptable limits
for zinc and phosphorus content of an oil. However, two things are important to note here. First of all,
anything over a 30 weight oil (ie. anything other than a 0W-30, 5W-30 or 10W-30) is NOT required to
meet the zinc and phosphorus limit imposed by the SJ specification. In other words, a 10W-40 or 20W-
50 motor oil can be rated SJ without being limited to the lower zinc and phosphorus levels.

We now have SM API rating that go beyond the previous SH AND SL..all reducing ZDDP. Eventually it will become extinct in API rated street use oils.

Hope that puts things into perspective.

Having said all that Brad Penn makes an oil with high ZDDP for racing for $3.60/qt. (20W-50)

Mercury Semi-syn is supposed to be excellent as well.

With V-twin you simply have the toughest oil and additives around is all.

They use a 30wt

Notice the warning not to use it with catalytic converters. It has lots of zddp.


Volvo Penta Marine is now Fully Synthetic...hope this helps in making your descision. It is a reall good oil. Out of stock due to springtime demand.

Outstanding!! However Amsoil's 15w-40 marine syn is about 1/2 the price with about the same additives.

Redline does make pretty good oil, but like you said, and that is why I use it too, AMSOIL is actually better and about the half the price!

Where do you get Amsoil is actually better?

10 case discount of Redline from BSR comes in at $6.51 a qt ($78.15 a case) You telling me you're buying AMSOIL at $3.25 a qt?

I don't know where you buy Redline at, but where I'm from it is typically $12-$15/qt. If you can get it at that price, that is a great deal. Redline is a pretty good product, not saying its not. I just know its expensive here, and tough to find. I just prefer the company of AMSOIL, and their products. By the way, your math is a little off, $78.15 divided by 10 is $7.815, which would round up to $7.82/qt.

I can't see the web page from the above link , got the following message:
The Volvo Penta Online Store is only accessible to visitors located in the United States**. Please contact your local dealer for information concerning Genuine Volvo Penta Parts

but in Europe Volvo Penta sell the following oil: http://www.volvo.com/volvopenta/uk/e...ne_engine_oli/

It is a fully synthetic oil SAE 15W-50 API SJ, ACEA A3/B3 for all year round use. Specially developed for high performance engines. Provides excellent protection against wear under severe running conditions at both high and low extremes of temperatures.
