Yup loved looking through the catalog when it would come in the mail..ah yes the JC catalog...all kinds of crapola, I mean worthy items...
How do you quantify that the engine runs so much better? I've tried various grades in various vehicles and it feels exactly the same to me when I drive them no matter the grade.I've had the same results, long term, in my vehicles. I contribute it to piston ring seal. Last Fall I went with 5w-40 and over the winter MPG's fell slightly from average. We will see what happens this Summer.
I'm not giving up on 5w-40's. Engines run so much better.

I would wager a blind Pepsi-Challenge test would say otherwise at least with the audible/smooth comments...Quantify? Easy if you're not deaf, a drone driver, and monitor the dipstick
HTHS for me equals smoother/quieter engine with less oil consumption.
Enjoy the 5w30. Now go out and use a 0w40 next time for another 2mpg
Same here. I must not be that in tune with my whipsHow do you quantify that the engine runs so much better? I've tried various grades in various vehicles and it feels exactly the same to me when I drive them no matter the grade.
I’m thinking double EPA estimates with SAE 50 racing oilI'll have him up to a +6mpg 15w50 and +8mpg 10w60 in no time, since +2mpg from the 30grade and potential +4mpg from the 40 grade just isn't greenie enough
Maybe not, now that I read this manual. For years H/K has allowed xw20, xw30 and in some cases xw40 in the 4 cylinders. This '23 Sonata only lists 0W-20.I'm also switching to a 30 from 20 for the 2023 Sonata. Not for any other reason than I have so much of it on hand. I guess another benefit is it keeps both vehicles on the same oil. In my case at least, i've never noticed an mpg difference attributable to an increase in visc.
Very reasonable to consider it and yes, as much as everyone chirps that "they have to prove it was the cause" what a mess if you do...so much easier to remove that variable.Maybe not, now that I read this manual.

I know, I know, an increase in viscosity is perfectly fine. Yes, you and I know this. My concern is unnecessary, drawn out disputes with a dealership and/or the mfcr. Don't need the headaches.
These are legendary! If Big Oil just didn't kill the inventors.I'm still waiting for those +100 MPG carburetors that big oil companies don't want us to know about.
VW built a 3 cylinder Turbo diesel that got 235 MPG years ago we never saw them market it did we!I'm still waiting for those +100 MPG carburetors that big oil companies don't want us to know about.
