New Vehicle Oil Choice

[autoapprentice]

Hello all!

I recently purchased a 2026 Honda HR-V. I am going to change the oil at 500 miles for break in, and I’m trying to make the VERY important life or death decision on which oil to use .

I have decided to use either Honda Ultimate Full Synthetic 0W20, or Mobil 1 Advanced Fuel Economy 0W20. Grok says that the Mobil 1 edges out on top due to lower Noack 10% V Honda’s 12%.

let me have your input!

Any chance they’re the same oil????

I’d buy the cheapest and go fishing.

Mobil ESP, Castrol EDGE Extended Performance, and Pennzoil ultra platinum 0w-20

Um, no, unless somehow Mobil started making oil for Philips 66 all the sudden.

Honda actually doesn't want you to change the factory oil early. They want you to wait until the minder to do the first oil change. They use a special break-in additive from the factory.

But you can use any 0w20. Nothing wrong with Honda OEM oil or M1 or whatever is on sale when it's time to do it.

First step don’t ask grok.

Yes, hello, hi. What is this special break-in additive from the factory?

 

[MParr]

Valvoline Advanced Full Synthetic 0W20 or Mobil 1 ESP 0W20.

Why not? Its nice to compare its results to my research.

The results I’ve seen haven't been very impressive.

Mobil ESP, Castrol EDGE Extended Performance, and Pennzoil ultra platinum 0w-20

+1, I have had good results using these oils in both my Honda Passport and Subaru Outbacks in recent years.

After full engine break-in, and if you are wanting to spend extra money, you could possibly go with Amsoil Signature Series 0W-20. It has a NOAK of 8.5%. I don't use it because I am too cheap. We have a guy here could maybe line you up, if you are interested. @Pablo I will leave you a link here. https://amsoilcontent.com/ams/lit/databulletins/g2880.pdf

Then see how longvthe engine lasts.

Honda does NOT use any break in oil or additives at the factory. They do use a grease lube high in molly during engine assembly.

Pennzoil Ultra Platinum 0w-20 is a fine oil is what I run in a 2024 Subaru, and Fram ultra filter, all from Walmart at a reasonable price,good idea for a couple of early changes. or Amsoil after you put on a few miles, there really is nothing special about Mobil 1 only their AFE is a good oil .

Can't say whether it's the oil or grease mentioned above, but here's a link to the UOA I did on my Pilot at 494 miles. Lot's of wear metals, so felt good about getting them out of there.

I went with the AMSOIL Signature Series, as I've used their products for almost 50 years. Switching to HPL Premium Plus PCMO in the next couple of weeks and it will be my "forever oil" (I bought four cases on their Independence Day sale).

Had I to start over again, I'd probably just use a Mobil 1 product or Valvoline Restore and Protect, which both can be purchased at Walmart for $27/5qt jugs. I have a tendency to overthink things, and the Mobil 1 or Valvoline Restore and Protect, changed regularly, would have given 98.7% of what the HPL will (yes, I pulled that number out of somewhere the sun doesn't shine).

And in the end it doesn't really matter. Change it at 500, 1000 or whenever. All the break-in that a special lube would help facilitate is done long before then.

I'd much rather get all the initial debris out of the engine quickly.

I've also read that Honda uses high moly 'assembly lube' and recommends going the full OCI on the factory oil.
I've done an early OCI on every new vehicle I've ever bought although I have gone from doing one at 800 miles to now going about 2500 miles. Since I don't see many Honda's with engine issues at low miles I'd tend to believe the Honda engineers and I'd probably go about 4K on the factory fill if I bought a new Honda (split the difference).

I can’t think of any reason why I would ever use the oil sold at the dealership. It’s not going to be as good as the major brands. And with the dealership prices it’s likely more expensive too.

My mother does this with her vehicle. Buys only dealership oil and filters and takes it to her mechanic to change. Swears it’s better. Oh well, at least she is trying to do the right thing and take care of it.
