I have seen many vehicles go over 500,000 miles running conventional oil. Kinda makes you think that it's not so bad.
More uniform molecules = less friction

Synthesis processes still create a wide distribution of molecular weights, so you can get products from small molecules to heavy waxes. Hydro treating or distillation gets a narrower range, but there is never a truly singular molecule or molecular weight.
Sure, there are no aromatics, and the ratio of linear and branched molecules, single or double bonds, etc will be different, with the products more uniform, but practically speaking it will still look like the picture on the right.

That image illustrates pretty well how synthetic oil would lubricate better since the molecules are all the same size. You guys that are running conventional oil, are you concerned about this?
Not at all, my Optima with the QSGB runs queiter and smoother than my Forte with the synthetic in it.

I'm not disputing your point that we're all here to learn more about lubicating oils.
Yes, one of the benefits of synthetics is that they have more uniform molecule sizes.
However, the graphic shown is really silly and does little to educate anyone.
There's also the problem of ordinary Grp II oil yielding long-lived engines.
A good syn may keep an engine cleaner, but the yard won't give you any more money for an aged hulk just because the engine looks really clean through the fill hole, and nobody will buy a 200K+ engine for more than metal scrap value just because it looks really clean.
You can make any engine look really clean through the fill hole with a little bit of spray can solvent.

The picture is silly, just marketing junk. ... Since molecules are on the order of a tenth of a nanometer, too tiny to matter if they are all diff sizes. I think they were trying to convey the more closely controlled, intentional design parameters met with synthetics, thats all.

I used to weigh 235 Lbs now I am 183.5 pounds so I am a different size.
Whoops, wrong Molecule.

For your next trick, see if you can change yourself from a mixture to a pure compound.

Synthetic oil is better...period. If the price was the same, everyone would use it and you'd be stupid not to. Synthetic oil is slipperier and lubricates better - efficiency goes up - horsepower & economy both up. Engines last longer. Maybe in a few special cases where dino doesn't leak out on an old car could you make a case otherwise.

Synthetic oil is more slippery now is it? Synthetic oil gives more horsepower now too?
And it makes an engine more efficient?
Dude. How long have you been here?
And do you really believe what you wrote?
Do tell. I'd love to see even 1 dyno pull where a synthetic made more hp than conventional.
And efficiency has nothing to do with oil,so unless engine oil in some way redesigns an engine and improves its efficiency then that is some real special oil.
Posts like this make me question why a person is even here.
Do you even read the actual data posted,or just regurgitate marketing fluff.

Thats why I LOL'd......the more slippery part was the funniest.

I've never seen any real evidence to say synthetics have less friction or even have less wear than conventional dino. Lots of evidence does say synthetics are more chemically stable, longer-lasting, leaves less deposits.
Slipperiness (less friction) has more to do with viscosity and friction modifier additives and less to do with the base oil.
Its hard to find reliable wear evidence, yet the current Castrol GTX Synblend 5w-20 & 5w-30 claims an 18 micron score on the Sequence IVA wear test, and the current Mobil 1 claims about a 19 micron score on the same test (the SN limit is 90 microns, smaller number better). For other oils its almost impossible to find out how they did to compare, but at least we have those two, one on the bottles/jugs, the other on their website, assuming marketing isn't lieing to us.
