Mobil One High Mileage Synthetic now api rated SN

Is that good?

 

or bad?

 

Hopefully the rating are backwards compatible. Other wise, we have planned obsolescence in action here.
API Engine Oil Classification

 

Also note the Mobil 1 High Mileage is designed to reduce oil losses, but I am not having problem with oil losses, so I just use regular Mobil-1.

 

i didn't realize that it is not compatible with all model years.

 

I noticed there are several Mobil-1 oils.
What one would be recommended for my 2017 Liftback? I know enough to use 0W20.

 

Neither did I.
I have also been assuming backward compatibility, but I do not know that for sure.

 

The ratings are backward compatible.
From http://www.api.org/oil-and-natural-gas-overview/fuels-and-refining/engine-oil/~/media/Files/Oil-and-Natural-Gas/Engine%20Oil/MOTOR_OIL_GUIDE_2010_120210.ashx

For automotive gasoline engines, the latest ILSAC standard or API Service Category includes the performance properties of each earlier category and can be used to service older engines where earlier category oils were recommended.

So the answer to the question in post 2 is that this change is good.

 

"High Mileage" is a red flag for me, typically implies a last-ditch effort to stem oil consumption in an older engine. It swells rubber gaskets/seals in the engine. If you subsequently use regular oil, non high-mileage, the rubber again shrinks, and your oil consumption increases with a vengeance.

Bottom line, avoid high mileage oils unless they're necesitated by high oil consumption, and be prepared to stick with them if you start.

Looks like 2 formulations for 0W-20 Advanced Fuel Economy and Extended Drain.
Either is fine. Since I like to procrastinate on oil changes, sometimes I use extended drain.
The Mobil-1 oil filters are highly rated on Amazon, so I try to use those if I have a chance to order ahead.
Used to be Walmart carried the M1 filters in the store, but now you have to order them.

 

How do the M1 filters compare with Toyota OEM? My son uses the Toyota filters on his Prius v and I use them on my other vehicles.

I see Advanced Fuel Economy & Extended Performance with AFE being less expensive.

AFE: Mobil 1 0W-20 Advanced Fuel Economy Full Synthetic Motor Oil, 5 qt. - Walmart.com

EP: Mobil 1 Extended Performance 0W-20 Full Synthetic Motor Oil, 5 qt - Walmart.com

 

I'm not enamored of Mobil. And up here Toyota 0W20 picked up locally at the dealership parts department is $5.91 for bottled liters, $4.50 for bulk (I go with the latter: cheaper, and no empties going into the recycle stream). And the Toyota filter is $8.53. All numbers in Canadian dollars.

 

Toyota filters from Amazon look to be $6.85 for 1 or 10 for $40. The Mobil One filter looks to be $16 each.
For Mobile One oil, Walmart appears to be the least expensive here.

 

That depends on what your definition of "compatible" is.
I don't see what the problem IS; especially not with an engine that already has "high miles" on it.

 

i don't have one, i'll check the dictionary.
