mobil 1 extended performance 15w-50

[panjs]

Metal, we're not dumb Canadians! After all, beaver is our national animal 

I'm running Mobil 1 15W50 in my Roadglide and it's OK. Canadian tire lists Mobil 1 starting about $10/liter. More $$$ than in the U.S but better than what you're paying for Amsoil.

The second post in this thread contains a question /answer that Mobil has in their FAQs.

Here's two oil reports using Mobil1 15w-50. The first one is good, the second should have tipped me off to a leaking injector.

For reference....

While I was in town this morning I  checked an Autozone here in SW Michigan.

Mobil 1 VT 20-50 $9.49/qt.  For that it oughta change itself.

Hey Barry:
I noticed that the column marked "make-up oil added" says 5 qts on the first test. What do they mean by that? It's not that 5 quarts were added in the 4928 miles, does it?
Just curious,

THIS IS FROM THE MOBIL 1 WEBSITE -

So how is Mobil 1 for passenger cars different from Mobil 1 for motorcycles?

First, let's be clear about Mobil 1's overall benefits compared to those of conventional motor oils, whether for passenger cars or motorcycles:

Superior long-term engine protection.

Superior high-temperature stability.

Excellent low-temperature starting.

Outstanding engine performance.

Low volatility/low oil consumption

It's a little hard to generalize about the difference between Mobil 1 passenger-car motor oils and Mobil 1 motorcycle oils. That's because not all viscosities of Mobil 1 passenger-car oils have the same levels of zinc and phosphorus, and there are even greater differences among the three Mobil 1 motorcycle oils. In general, Mobil 1 motorcycle oils have:

Additive packages balanced differently for motorcycle engine and transmission operation. For passenger vehicles, fuel economy and emission system protection are higher priorities. These require low phosphorus systems and the use of friction modifiers. Motorcycle oils do not require friction modifiers for fuel economy and for better clutch friction less/no friction modifier is optimum. Motorcycle oils allow the use of higher levels of antiwear additives such as ZDDP (phosphorous).

What are the overall advantages of Mobil 1 motorcycle oils?

In addition to the overall benefits listed above â€" specifically, high-temperature stability and low volatility/low oil consumption â€" Mobil 1 synthetic motorcycle oils also offer superior anti-corrosion performance compared to conventional motor oil, which is important in many parts of the country where bikes may sit in garages for several months of the year.

Compared to conventional oils, Mobil 1 motorcycle oils provide superior wear and high-temperature protection, and promote engine cleanliness and lower oil consumption.

Once you get past these general advantages, you have to deal with each specific motorcycle oil one at a time to understand the benefits.

What about Mobil 1 V-Twin oil? How is that different from Mobil 1 for passenger cars?

Mobil 1 V-Twin oil is designed for air-cooled, large-displacement bikes. Because of their design, these engines can generate very high localized oil temperatures and high overall bulk-oil temperatures.

As you know, a typical air-cooled V-twin's rear cylinder gets a lot hotter than the front cylinder â€" it's a matter of airflow. When it's hot out and you're stuck in traffic, the oil temperature in your bike climbs rapidly. Above about 250°F, conventional motor oil is going to break down. Mobil 1 V-Twin synthetic oil is good to above 300°F.

Like Mobil 1 Racing 4T 10W-40, Mobil 1 V-Twin has high levels of phosphorus/zinc and the same high-temperature detergent technology for superior wear protection and engine cleanliness, even at elevated oil temperatures.

With Mobil 1 V-Twin oil, you can go the full length of the manufacturer's recommended oil change intervals with ease.

Advanced Autoparts has Mobil-1 on SALE for $7.99 a quart for the V-twin 20W-50

As I remember it, their website states in multiple ways that the "motorcycle" oil blends contain friction modifiers since most motorcycles share the engine oil with the tranny/clutch; so in Harleys, since they're all separate systems, their "regular" motor oils are quite suitable for use in the engine.

Yes I did add 5 quarts. There was a lot of interstate riding at more than the speed limit. I guess that used it up or spit it out through the breather.
