What oil can I use in sportster primary?

20w50 oil
The Evolution Sportsters have wet clutch and primary drives. It is recommended to change the oil at 1,000 miles, then every 10,000 miles after that. The manufacturer recommends using 20w50 oil.

What can I use for primary oil?

You actually have a couple of choices for the primary drive. The optimum product would be Mobil 1 Racing™ 4T 10W-40 motorcycle oil, but it is also okay to use Mobil 1™ V-Twin 20W-50.

Is primary oil the same as motor oil?

Likewise, AMSOIL Synthetic V-Twin Primary Fluid is designed only to protect primary chaincase components. Its viscosity is similar to an SAE 50 motor oil. Formulating it as a straight-weight lubricant naturally offers an advantage in shear stability over other multi-viscosity lubricants.

What weight is amsoil primary?

The Primary lube follows the line of the 10W-40 weights allowing for easier clutch and shifting performance.

What is the viscosity of Harley primary oil?

The 20W-50 motorcycle oil’s viscosity is right in the “sweet spot” for optimum operation in all three holes and the volumes of positive reviews we receive back this up. Gear lubes do contain heavy doses of “extreme pressure” additives which many believe prevent transmission wear and provide quieter operation.

Can I put gear oil in my primary?

JMHO. Gear oil is measured differently than motor oil. 75w90 is close to the same viscosity as 10w40 motor oil. Just so long as it has no friction modifiers, it would be safe to run in the primary.

What viscosity is amsoil primary fluid?

Likewise, AMSOIL Synthetic V-Twin Primary Fluid is “over-engineered” to protect primary chaincase components. Its viscosity is like an SAE 50 motor oil.

What viscosity is Harley-Davidson primary oil?

What weight is AMSOIL primary?

What kind of oil do you use in your Sportster?

Lots of great oils out there – Amsoil, Mobil I Synthetic, Screamin’ Eagle SYN 3, etc. My wife’s Sportster Forty-Eight calls for 20W-50 and that’s what I use for the engine and primary/transmission.

Why does the Sportster have 2 holes in the oil?

And Not the proper way. Bubbie has you covered…the Sportster has “only” two “holes”…100% Synthetic oil may be used for the ENGINE to take advantage of the friction modifiers and higher temperature performance it’s purity advantage over “refined dino oil” which has some impurities dispersed within.

What is the shear stability of the primary oil in Sportsters?

In our Sportsters, the primary oil is particularly subject to high shear rates due to being shared with the transmission. After testing the shear stability of the oils above according to ASTM D-6278, nearly half dropped one grade to an SAE 40. Many of the oils losing a viscosity grade did so quickly, within the initial 15 cycles of shearing.

Why is the oil in my Sportster so dark?

Using a TC oil filter will burn up the sportster motor) As far as the sport primary/tranny/clutch lube color, It may be due to the type of oil used? and OR in need of Changing. Check the primary chain free play, as it may cause the color of the oil IF the chain IS too loose and rubbing inside the aluminum housing…
