Synthetic Motor Oils Other Than Harley-Davidson Oil Does Not Void Warranty Coverage |

Dear Mr. Scanlon:
Thank you for your recent letter requesting information on Harley-Davidson's one-year, unlimited mileage warranty when Synthetic Lubricants are used.
Until now, the Motor Company has never supported the use of synthetic products in our vehicles because there had never been any test validations completed on the numerous formulations in HD/Buell motorcycles to determine the viability of using these products on Harley-Davidson products until now.
We have developed a specially formulated synthetic fluid called SYN3. This fluid can be used in Harley-Davidson engines, transmissions and primary chaincases. This product had been exclusively designed for Harley-Davidson and is the only synthetic product tested and certified by Harley-Davidson engineering for use on HD/Buell motorcycles.
The use of a different brand of fluid does not void the one-year, unlimited mileage warranty unless it can be confirmed that the use of such products was the cause of the failure.
Thank you, Mr. Scanlon, for taking the time to write to Harley-Davidson and allowing me to answer your questions.
Sincerely,
Lisa Sagen

"I couldn't be happier with the AMSOIL products! I feel like I have an edge over the competition when it comes to performance and durability and that's a great feeling when the going gets tough. Our race program uses most everything in the AMSOIL line. As a matter of fact, we began using AMSOIL in our team transporter's diesel (engine) and we're getting increased (fuel) mileage and it's lowered the overall operating costs. Our team truck is constantly going back and forth across the country from race to race so the difference has really been noticeable." ~Mike Larocco |

| Motorcycle Testimonial: Just thought I'd give you a report of my recent engine repair. I had to replace the stator, which on a 1200 Wing involves pulling the engine. Since I had the engine out and had some coolant problems, I also did the head gaskets at the same time. On removing the rear engine case I found no sludge what so ever. The only thing was a light brown film on the inside of the case which wiped right off. While replacing the stator, friends suggested it would be a good time to replace the clutch friction plates. I purchased an aftermarket clutch
pack and proceeded to remove the old ones. Also, when I removed the heads, I found just a light carbon build up on the heads and very light carbon at the ring turn area. I use PI on a regular basis as this helps eliminate a backfire problem on the 1200's with the afterburn valves getting stuck from build-up. Also, the cylinder walls had all the factory cross hatching from the original honing. My compression readings have been within about 5 lbs. of factory new specs. All in all, not bad for a motor with 186,000 miles and 25,000 mile oil changes!! Guy
