I was shopping for oil a couple of weeks ago and it appears all the oil is called" synthetic" of some sort now? I always thought oil was a synthesized product since at least multi weight or before?

synthetic :" noting or pertaining to compounds formed through a chemical process by human agency, as opposed to those of natural origin:

if you Costco watch their oil for deals , my co-worker keeps telling me about deals on full synthetic motor oil at Costco

I don't have a membership

Farm and fleet had a stock up sale on oil this winter bought a couple cases of synthetic blend for 2 something a quart

Just crawled undah the pick up this afternoon....and changed my oil and filtah. Put a little coat of oil on the filter gasket and hand tighten. Soon as it staahts dripping ..I put the plug back in. Add oil and go.

Most of the 'synthetic' oil is actually just homogenized like milk meaning the molecules are all the same size.

Don't over think that one. I take the plug out, get the rest of the stuff together, change the filter, put the plug back in and fill her up. Sweating if ya got that last shot glass full out of the engine or not just aint worth it.
