Can you change from SYN oil back to dino oil if wanted? I'vehave heard that you can switch backand then that you can't so which is it? Have run SYN for the last 7500 and looking at options.

 

Not the answer to your question, but why are you switching from syn to dino? Thanks.

 

I've always heard that you'll have a good chance of developing leaks if you switch from syn to dyno. And anyway, why on earth would you want to?

 

Not going to. I've heard this discussion a few times at work and was wondering what problems would come up if you changed back (actually have someone here who did this recently).

 

In a modern engine seal comptability is not a problem. Besides IF any leakage where to happen it is normaly going from dino to syn, not the other way around. Syn will clean up gunk encrusted seals in an engine that has been running dino oil for a long time then, if the seal is bad, it will leak. Also Harley motors run hot. Dino oil starts to break down at a llttle over 300 deg. F. Syn is good to over 600 deg F. I have seen oil temps of 270 deg F on my Ultra during the hot summers. A little to close to the point where the dino oil starts to go south for me. In answer to your question, YES you can switch back and forth all things being equal but why in the heck would you want to. The worst syn is better than the best dino oil in my humble opinion.

What my independent dealer told me he read this article that stated you shouldn’t mix oils brands once you started, seems like the different additives used in different dino oils causes sludge and stuff, I didn’t read it, but he is a pretty honest guy and most important doesn’t sell all that much oil : - )

I will never go back to dino and I won’t try to mix synthetic oil, well the first time, I will run Mobile V Twin for the first time (50 miles) then dump it and the filter,from that time I will run MCV AMSOIL 20-50

That is true. You shouldn't mix oil brands i.e. add a quart of a different brand to what is already in the bike. In other words. Say you are running Harley Dino oil and you are down a quart and you can't get the Harley so you add a quart of another brand of dino oil. That is not a good idea. It won't hurt anything but you should change it as soon as possible. All Dino Oils cause Sludge. Some more than others but they all cause Sludge. I don't believe your dealer steered you wrong.

Ask your dealer to set you up as a Prefered Customer. That way you can buy all the AMSOIL products wholesale.

 

Yeah, I knew that. Just a temporary brain fart when I was answering the post. Blame it on premature senility. Well, probably not too premature at that.[sm=smiley24.gif]
