I have tried

X1R and had GREAT results, Much smoother, MUCH queter! Its an oil additive not a synthetic.

Yes, you can use it but

Why? It last longer but you don't use your engine that much anyway. It has a lower starting temperature but you don't boat in sub zero temperature. I don't think you need it!
