hello,

bought some PS white 3 years ago while in the 12 degree weather of dallas, texas during winter. used half of the bottle and then headed to socal. still have half a bottle of the white and wonder if i can still use it? does it have a shelf life?

thanks,
david

Should still be good. Just shake it up really well before using.

Also you can use it year round so you can use it all up. It will provide lubricity and a small cetane boost. The cetane boost isn't as much as the performance blend but it is still there.

I don't think there IS a shelf life on that stuff.

how safe would the power service white bottlle be for an 06?

Completely.
