Specto golden to yamalube?

[YZ Freak]

Hello everyone, I have always used spectro golden 10w40 oil (except for the break in period), in my '99 YZ 400. I have two containers of yamalube semi-synthetic 10w50 oil. I would like to use the yamalube oil up. My question is this- Would it be safe to use for one time? Is this O.K.? Thanks.

You'll be fine. Any good oil will protect the engine, the key to long engine life is oil changes .
