There is a small leak in the rocker cover on my Sportster and the dealer said it's because I am using synthetic oil. I heard this from more than one Harley shop. They also said the engines are noisier with synthetics because they are so thin. What the heck started that tale? They are too thin and that is why it leaks.
So I am wondering if synthetics have a different surface tension or something that might have started this rumor.
I sure hope what they said is not true because I just bought a case of Redline 20W50 oil.
I am also doing a test on a piece of bare metal with Redline and conventional oil. The metal is out in the weather to see if there is a difference in how fast rust forms where there are a few drops of each type of oil.
