Ox66 oil recommendation

[acsockr3]

New to the Yamaha side. What oil is preferred for the 2004 vmax ox66? Haven't heard many good things regarding the yamalube.

[bassboogieman]

I used Yamalube exclusively in an OX66 for 7 years, no problems. It's more expensive than generic but I use the manufacturer's products in my outboards.

Mine is a 1999 225hp...all I ever ran is yamalube and ringfree with no problems.

Amsoil HP marine, interceptor, merc full synthetic. The yam oil is good but it is just dirty. Cj

I have use Pennzoil XLF or prem plus 11 years and have no issues. I run a can of Seafoam they every other tank. Inside of Prop is spotless and never have any carbon in my O2 sensor. Smoked too much on yamalube and fouled the O2 sensor.

Good info. Mine smokes a lot and heard that other oils may burn cleaner.

Amsoil, 17 years worth in a OX66. Mine smokes on start up, my plugs are NOT fouled. I use Amsoil, and Ringfree ---- but I fish a lot of no wake lakes, my O2 sensor and the sniffer tube still needs to be decarbed every year

[Reata210]

I ran Yamalube in my 92 Yamaha 130 for 17 years and that is what I feed my HPDI. Has worked for me.
