Proven Performance® Protection: S&S Lubricants

Superior S&S® Lubrication For Your American V-Twin

S&S Oil

S&S Cycle is pleased to introduce a new line of premium drive train lubricants to keep your American v-twin motorcycle running like new for years to come. S&S has long been known for building the biggest, baddest engines on the salt, strip and street, so it only makes sense that the same company that provides the parts should offer a way to protect them from the rigors of high performance riding. Make no mistake, though, you don't have to be a racer to benefit from world-class S&S lubrication. Whether your rides last a quarter mile or cover a continent, S&S engine, transmission, and primary oils provide the best protection available. S&S lubricants are manufactured exclusively for S&S by Spectro® Oils of Brookfield, CT and are the best choice for stock Harley-Davidson® and S&S high performance engines.

Why should I pay the extra money for synthetic motor oil?

It's a matter of "Pay me now, or pay me later." Synthetic motor oil reduces wear and makes your engine last longer because it does a better job of lubricating moving engine parts. Since it also stands up better to mechanical shearing and high temperatures, it maintains its lubricating properties much longer. To put it simply, synthetic oil lubricates better right from the getgo, and it keeps on protecting your engine from the time you pour it in to the next oil change.

Can I run multi-viscosity motor oil in my shovel?

Yes! And not just shovels. S&S multiviscosity motor oil can be used in any engine regardless if it has iron cylinders.

Isn't 20w50 thinner than SAE50?

The answer is yes, but not really. When it's cold, 20w50 is thinner and flows better than SAE50 at the same temperature. If your engine could talk, it would thank for using 20W50 instead of SAE50 every time you start it cold. Multi-viscosity oil flows much better at lower temperatures, so your engine will get lubrication much quicker than it would with an equivalent single weight oil. The important thing to remember is that most of the time your engine is running, it's hot, and 20w50 has the same viscosity as SAE50 at operating temperature.

I've heard that synthetic motor oil is too slippery for the roller bearings in my lower end?

Oil is the life-blood of your engine, so give it a transfusion of U.S. made S&S engine oil.
