There was a change to SN rated oil....(SN plus)
API SN Plus Introduced in May 2018
Licensed from May 1, 2018, API SN Plus is a new API classification that can be used alongside API SN, API SN with Resource Conserving and ILSAC GF-5. It was developed in accordance with OEMs request for motor oils that can protect from the potentially catastrophic effects of Low-Speed Pre-Ignition (also known as LSPI
Engine manufacturers have been striving for a long time to reach higher and higher efficiency in their engines combined with lower and lower fuel consumption. One of the most efficient ways for a gasoline engine to operate is to use direct injection. LSPI can only happen in engines using gasoline direct injection technology.
So, what is LSPI and why does it happen? When the fuel is injected in the combustion chamber it may form a liquified solution with the thin residual layer of oil that sits on the cylinder wall. This fuel-oil solution is then pushed upwards by the piston during the compression stroke and the pressure may cause it to ignite, thus resulting in an unplanned combustion pressure wave. This is the LSPI event. Afterwards, the spark plug ignites the remaining fuel-air mixture that results in a second combustion shockwave. The combined force of the shockwaves is enough, in the long run, to create cracks in the piston and eventually to cause sections of the piston to break away completely.
Realizing this problem, engine manufacturers turned to oil companies for help. Oil companies changed their additive packages in such a way that would prevent the fuel-oil mixture from combusting and thus preventing the uncontrolled combustion. The American Petroleum Institute introduced a supplement to their API SN specification – called API SN Plus – that also includes tests to verify that the oil protects against LSPI.
And for the first time ever I was not able to get Valvoline VR-1 Racing 10w-30 at my NAPA (distribution store). Asked if I could order it. Response....No can do. Looks like Amazon it is.

| Probably a liability thing. Somebody somwhere out that in their new car and voided the warranty and made the EPA mad. |

Im in New England, guy who owned the car before me used SAE 30. Im cool with that, but what about winter? I don't plan on driving the car after the first snow storm but I do wanna let it run every few weeks. I was thinking of going 10w30, but if I kept it at a standard 30 would it really hurt anything?
Also whats the deal with everyone running diesel oil? I see a lot of people using rotella ? |

I'd use 10W30 so you are covered year-round without thinking about it.
I use Rotella here because I like using 15W40 for Arizona.
The 40 is for when it's hot.
It's cheap and comes in a huge jug and ran cooler for me in the summer than when I tried another oil (I think it was Valvoline)
Rotella is/was often recommended because it had a better mix of chemicals (zddp ) that other normal modern "car" oils.

Look up VR1 racing oil by Valvoline. In my research, it has the right zinc and phosphorus in its makeup. I run 10-30 year around in Phoenix on engines with tight tolerances. Even in the summer heat, I have plenty of oil pressure.

30wt is fine, it doesn't use viscosity modifiers which can degrade from heat. No reason to start you car and run it, in fact it may well cause water to build up in the oil over time, a big negative. Fill your tank with ethanol free gas and block off the fuel inlet and run the engine at a fast idle until the carb is dry of fuel.
I run synthetics because they can take a lot of heat and its great having an all season oil like the 5w40 I like to use. Rotella T-6 though no longer carries an "S" rating which used to indicate it was suitable for use in gas engines. Don't know if this is really a problem or not, because VW air cooled engine are not at all typical in their needs. There are still other 5w40 Diesel oils that do carry a "S" rating, like Mobile 1 Turbo Diesel 5W40, which I continually look for on sale and sometimes find very good deals on. |

It says "high mileage" which may or may not mean it has enough potentially cat clogging antiwear additives to protect the lifters, I have not checked this out. **W-40 oils were not restricted in the amount of ZDDP they can run but a 5W30 or 10w30 SN "NON-HIGH MILEAGE" oil would have been restricted. Just don't know for sure where this oil sits.
Wonder how it compares to Mobile 1 0W40 with rates well in various wear tests? |

The picture I see says "ALL-Mileage", not "high mileage."

Yes you are correct, but what the heck is an All-Mileage oil? |

Sounds like a car repair sign I saw that made similar nonsense:
"Specializing in All Makes and Models."
There is even a current ad stating this oxymoron:
https://www.pachecoworldwide.com
Maybe suggest that the owner google "specialize"? |

 I don't know but I don't like the idea of high-mileage oils because, along with the higher zinc some claim to have for older flat-tappet engines, they nearly always claim to have additives that soften the seals and make them swell to help stop the leaks in all of those "high-mileage" engines. I don't need that in my newly-built ACVW motor with new seals.  Somehow I can't imagine that stuff being good for brand new seals, but maybe I'm wrong?
