did a delivery for Chevron today and it was a PAO sample. Asked the lab guy if this could be poured in the motor of my truck and he said it was 100.00% PAO and had not been treated, and that their plant only delt in the raw stuff not making lubes. I asked him that aside would it work, he said it would be better not to try because this PAO was too light, I asked him about using it as a fuel additive he said too heavy, I asked him the application and he said in small motors that are delicate, I asked like what and he said Medical Equipment. But I still wonder if it would work in my engine????? (just to try :-] ) Hummm, using PAO's in medical equipment!
