Hi,
I use the same mix ..
20W50 if miles are high on a waterboxer engine.  and temps are not real
low..
and the Lucas additive.
not a whole bottle ..but some.

I recently used some Lucas 75W90 gear oil and really like it just fine.

I often use Lucas fuel injector cleaner..
so far ..
I find the brand to be just excellent in every product.
