So, you did look into it.
And discovered what is widely understood by both ends and the middle of the automotive business, synthetic oils offer greater engine protection at extreme temperatures; better flowability in the cold and greater resistance to breakdown in the heat.
Synthetic oil is now offered as standard in all virtually all new vehicles because of the advantages it offers. Chevy, Chrysler, Honda, Toyota, Subaru, VW, Audi, Mercedes Benz, KIA, Hyundi are all fully synthetic out the factory door. Who am I missing, oh yes, Ford. Ford is currently transitioning from the synthetic blend it had been shipping its new vehicles with to full synthetic. By next year, Ford will likely be fully synthetic along with everyone else.
If anyone cares to google the question “does synthetic oil offer greater flowability in cold weather”, you will get ten pages of hits from sites A-Z all saying “Yes, they do” without a nay say to be found. Automotive sites, oil company sites, mechanic sites, even Consumer Reports, which I will quote:
Synthetics have some advantages over conventional motor oil. They’re designed to be more effective at:
• Resisting oil breakdown, which makes it last longer than conventional oil
• Withstanding higher temperatures than conventional oil, which helps keep engines running longer
• Flowing in cold temperatures, thus reducing engine wear during frigid startups.
• Resisting oil breakdown, which makes it last longer than conventional oil
• Withstanding higher temperatures than conventional oil, which helps keep engines running longer
• Flowing in cold temperatures, thus reducing engine wear during frigid startups.
But, again, what CR says is exactly what you will find everywhere else because that is what is widely understood to be the case, as it has been for twenty years.
Synthetic oil’s advantage in cold weather is as exactly as Bill said it was, though that didn’t stop Aqua from jumping in dismissively and saying, No you are wrong., I know better than you! Physics! And synthetic oil’s advantage in cold weather is exactly as I said it was (in support of Bill, who was dead ass right). And again, Aqua jumps in, No, no it doesn't. I know better than you! I'm an engineer! He even insulted the “hands on, skin in the game” folks at the Newfolden Bus Garage. And it just isn't right to insult and dismiss "skin in the game, hands on" common folk who get the jobs done and keep the wheels rolling.
And, well, that got things off on the wrong foot.
So, have you calmed down Skippy?
What I told Russell was exactly right without going to all of the trouble of trying to look up the specs on his specific car, which would in reality be very risky and I'm not going to do that to him.
By the way, here is a very helpful guide to what those funny numbers on oil containers are, they're viscosity ratings that SAE, as an automotive standards setting body, publishes and certifies (I used to belong to SAE, I've spent many a day going from the west side of Detroit to Troy- on the east side of Detroit- for SAE meetings) based on tests done to API standards. Here is a quite clear explanation of oil viscosity, including the definition of "multi-viscosity". You may want to read it.

I just sincerely answered Russell's questions and what he should be focused on when talking to the technicians. They will know what his manufacturer recommends (it's in their computers accessible probably by VIN code. For the love of mercy, don't make me have to explain what a VIN code is and where it comes from.)
Now please just go back in whatever hole you spring out of and leave me alone.
