Hello there,,,

I have 2- Stroke engine 225EFI mercury 2006, and I am using CTS Advance quicksilver oil, and want to switch to quicksilver premium plus oil, and still have some oil left on the reserve oil tank.
So is it okay to mix the CTS with premium plus oil?
And if I have to drain the oil out of the system, how can I do it?

Thanks
d:)

if your engine is still in warranty, use what is specified by the manufacturer. until the warranty expires. just to be safe.

As long as both oils are TC-W3 rated it will be safe to mix.
