Now the oil I just looked at picking up for my truck says Conventional/synthetic blend on it. Just seems odd to add the two together.
I am no oil expert, by any means. But aren't all non pure synthetic oils a synthetic blend? I mean, even petroleum based oil is not straight out of the ground. It has additives. And those additives are man-made; which means synthetic.
So, every bottle of oil on the shelf (except the pure synthetics) is some sort of petroleum and synthetic "blend".
I personally, have never seen a definition of how much synthetic additives it takes to be able to be labeled "synthetic", "semi-synthetic", or "blend" or whatever.
Does anyone here know?
