Default Amsoil question...

I currently have Amsoil 20-50 in my ride. Can I top it of when necessary with one or two oz. of Mobil One V-Twin 20-50? I have a quart of it laying around on the shelf and currently have no Amsoil.

Do they mix ok?

I'll be interested to see what the 'experts' say ...

I'd be inclined to tell you 'yeah' ... because I've done it myself (not necessarily Amsoil and Mobil One, but X and Y) ... in addition to synthetic and traditional mineral oil, there are blends ... so, I'd have to think it must be okay ...

... in your case, you're just mixing synthetic and synthetic ...

... as I say, I'll be interested in the 'professional opinions' if you get any ...

I personally would be happy to mix/add one synthetic to another, but not a mineral or semi synthetic with a fully synthetic oil. Just my pennies worth.

I would think it would be better than running low on oil!

What he said! + Even if you had to add 1/2 a quart it is all oil. Of course the oil gods will tell you NOOOOOOOOOOOO! No mixxy!

I'm no "expert"but I wouldn't worry about it too much. They should mix just fine.

Synthetic of the same weight should be fine. Fwiw, mines running better with Mobil1 since I switched from Amsoil.

I'm about to do my 1K oil change, brand new FB, and I'm going to use mineral in all three holes from start to finish with this bike. I used syn. in my Sportster and that thing leaked like a sieve. My buddy runs syn. most of the time including Amsoil and his bike REALLY leaks like a seive! Let he without syn. cast the first stone. Sorry!

Thanks for the input guys. I ran dino oil until 20K miles. Then I switched to Amsoil and had the bike serviced today again @ 25K with Amsoil again. There is always 1/2 quart leftover and I lost it driving home today. (operator bungee error!).

But I usually lose a few oz. every 5000 miles... this is why I ask.

BTW, the bike runs well with Amsoil, no leaks, but is definately noisier at the top end of the sewing machine. I run 20W-50 in 2 holes and Severe Gear in the tranny.
