Oil Choice For New Honda 3.5L

As for Mobil making Toyota oil... AFAIK Genuine Toyota motor oil and Mobil 1 use the same base oils. You might be correct in saying the additive package is somewhat diiferent. For the sake of discussion, let's assume the additive package is different. So what? Different does not mean it's better or worse. It means a different approach was used. Both approaches can be good. Do you think Toyota knows more about making oil than Mobil does? Mobil made the Toyota oil with the additives that Toyota requested. If Toyota and Mobil 1 oils have some differences in additives, I'm equally confident in both brands of oil. Also, having the same or very similar base oils would make them similar. I have equal confidence in both, but M1 costs less at Walmart.
This is a whole lot of word salad to just say, "Mobil 1 and TGMO are different oils. They are both acceptable, regardless".
 
OEM Genuine Honda motor oil is made by Idemitsu. It's the same motor oil, but it's cheaper when purchased with Idemitsu name on the bottle. Rockauto, NAPA and some other autostores sell Idemitsu oils. Oreilly does not.

OEM Genuine Toyota motor oil is made by Mobil (according to Lake Speed Jr). At least for Toyota oil sold in USA. It might differ elsewhere in the world. As far as I know, all Toyota oil is synthetic oil. It's Mobil 1 oil in a Toyota bottle. You can buy the same oil for less money by buying Mobil 1 from Walmart.

I'm not suggesting anyone needs to limit themselves to those car brand OEM motor oils, but if you want to stay with them, then I suggest buying them from lower cost sources as I described.
Has this changed in the last 6-12 months? Because this is Hondas ultimate full synthetic oil:

And this is P66 oil:

1753477625693.webp



Notice any differences or similarities?

Oh, also this too:

Idemitsu made Honda oil in prior years. Then they went to P66.

Honda and P66 have a huge partnership now, including their racing section: http://phillips66lubricants.com/news/honda-racing-partnership/

It seems unlikely that Honda would have huge partnerships with P66 and switch back to Idemitsu so based upon this info, I'd say the Idemitsu is old/outdated or Honda is making multiple partnerships that aren't public to deliver their oil to customers, maybe depending on geographic locations.
 
With the cold and short trips, I would recommend doing OCI at 5k not MM. Do one or two UOA after your normal intervals, use Oil Analyzers or others that do GC (not Blackstone) and make sure to request the GC for fuel dilution. I didn't request on one from Oil Analyzers so they didn't do it. Base your OCI's from there. The Lake Speed thing is good but that will give you results possibly 4 years from now depending on use.

I drove my wife's '19 Pilot a bit longer to get it hotter but no long trip. The oil test IMO was what the motor sees everyday, no special accommodations. Lots of short trips, sits outside 24/7/365, not as cold as OP. https://bobistheoilguy.com/forums/threads/blackstone-vs-oil-analyzers-pp-euro-l-5w-30-5175-miles-19-pilot-67k-miles.392379/#post-7154514

M1 ESP has more certifications and an excellent choice. For me the VRP is in my Pilot with a big reason that the VCM is active and knowing history of ring issues caused by VCM in older Honda's. I'd rather prevent that issue and changing earlier is helpful IMO. UOA is great reference and I do them. The cost of UOA = DIY cost of oil change for me or basically like changing every 2500 miles with no UOA for same cost. One of my vehicles is on 3k/6 month from tested fuel dilution, one is now on 4k changes that had motor replaced due to oil burning, stuck rings, scored cylinders at ~7500mile maintenance minder changes at dealer prior.

The VRP 0W-20 is easy to get, will keep it clean, satisfy warranty documents, not expensive for early changes. If your UOA shows high wear metals due to short trips and fuel dilution, bump to higher grade like 5W-30 VRP. Keep all the information and if any ever issues you can show why you went higher viscosity.

Next oil change in the Pilot I'll probably do a UOA just to check on the VRP 5W-30 as this is my second OCI with it. Might be a bit off as it will be probably about 5500 miles with a 4-5 day, 1000 mile round trip to Virginia upcoming in 2 weeks.

What you said seems plausible in regard to Honda Genuine motor oil. I wonder if Idemitu is still making Genuine Honda PSF, DW-1 ATF, gear oil, etc?
