Use of Amsoil
I have been using Amsoil for about a year and needed to do some cam upgrades. Shop knew I had been using Amsoil and suggested I have rear exhaust valve checked for deposits. They indicated they had two other 88's with locked up exhaust valves where Amsol had been used for approx 20,000 miles. I was no where near that mileage but did see some build up on mine. I used the oil because the word on the street was it was best. Shop said that as oil ages it would thin out when hot and blow-by would build up on valve stems causing them to lock up. Hope Amsoil is aware and looking at the issue.

Just make sure you run a oil that has zink in it. A lot of dino oil has no zink due to
it eats cat converters up. All racing oil has some in it.

Currently have Mystik JT-8 15w-50 in my TC, service manual says use an oil certified for diesel engines if HD oil is not available. Seems to me most of you believe sales hype instead of your manuals. Thats fine by me, although it seems like there are a lot of amsoil dealers on here. It could be the additve package of oils for diesels have more in common with hd 360. It could be the moco knows whats best in their motors. It could be I'm gettin old and would rather believe a manufacture instead of having sales BS forced down my throat.

If you think Harley know whats best in oil for the motors they build, why do they get the oil they sell from the lowest bidder, and when a voa is performed on that oil it has the lowest amount of anti wear additives among the most popular oils sold and used in this survey?.If you go to the bitog site you can look at all the different oils that have been tested and chances are you wouldn't pick Harley oil unless you were out of oil and it was the only thing available. Like you said Sales hype, Harley uses it to.,,
