Hello all I just did my first UOA on my 2020 Honda Accord 2.0T using Quaker State Full Synthetic 0W20. The car is modified and sees track days which is why I changed the oil after just over 2000 miles. Let me know what you guys think. Thanks.

Thanks! The viscosity is my main concern QS FS 0W20 is listed at 8.33 and mine was 6.6 after just 2100 miles! I think I’ll be switching to 5w30.
Where did the MM say you were?

Im curious to see how many of these UOAs out there where the guy went the distance the MM suggested.

I recall it saying around 80% maybe 70%. I never go based off of that because my car is driven harder than most other Accords that is. The MM is just a general gauge and shouldn’t be the only factor when doing an oil change.

Actually the MM is a highly tuned piece of code with a variety of input penalties including " hard driving" which if I recall has about a 2.4X degradation factor applied.

I wholly recommend you investigate it at minimum, there is a ton of knowledge in it. Its pasted here elsewhere.

Thanks for the info I didn’t realize it was that sophisticated now I thought it was just a “general” rule of thumb to go by.

Noticed QSFS was still $23 at Walmart - hard to walk past but my shelves are stocked …

You should be measuring fuel dilution with these engines, and your report is missing it. Given your drop of viscosity, its most likely diluted. I had similar experience with this engine and mine was highway miles mostly. Shorter OCI and/or 5w30 is the way to go with Honda 2.0t. Use cheapest oil, all the fancy oils will do nothing for fuel dilution

With the wear metals being so low would it be wise to just keep using 0w20 and just changing it every 2000-3000 miles and after each track day ? I’m going to do a fuel dilution test next go around and see what it’s at.

Take a look at my report https://bobistheoilguy.com/forums/threads/mobil-1-0w-20-ep-7-4k-mil-acura-rdx-2020.359165/

My iron was a bit high, but I had 7400miles on it, the wear metals do increase with longer OCI. No racing, just easy highway mostly.

If you going to measure fuel dilution, use Polaris lab as they are more accurate for fuel dilution.

Since your viscosity dropped so much at such a short milage, one grade up should help a bit.

Did you switch to 5w30? How has it been?
I have a 2022 on ktuner stage 2 but I don't race, just 90% highway driving.
