2024 Rav4... Idemitsu IFG7 0W-16 VS. Pennzoil Platinum 0W-16

[GenSan]

2024 Rav4 Prime XSE each oil was run hard for 4,000 miles each with a Fram Endurance filter.
Would you be comfortable extending either oil out to 8,000 miles and which one would you choose, Idemitsu or Pennzoil Platinum, considering both oils had decreased flashpoints and the viscosity was at the lower end for a 16 weight? I am awaiting a 6,000 mile UOA on Ravenol EFE 0W-16 and will post as soon as I receive results.

I think it's too early in this engine's life to be making such decisions. Let it finish breaking in. Also, sticking with one oil will make it easier to interpret UOA data.

Its a very new engine so the metals are really just noise at this time... not meaningful yet.
However I am not comfortable with 5.6cst. I'd probably use 0w20 hybrid oil or 0w20 m1 x2 esp.
or other 0w20 with vw508 spec.

Exactly what @himemsys said. Too early but PP probably being easier to obtain? I'd side with it and you know the whole made from natural gas is supposed to be a cleaner process.

Question: is mileage on a hybrid engine similar to a normal IC engine? It seems to me that the hybrid engine sees a lot of start and stops, but it doesn't run all the time the car is moving, so actual running mileage is lower.

And FWIW, I'd be inclined to run 0W-20. 0W-16 just seems dumb.

I don't keep track but according to dash I use between about 30% to 60% ICE. It depends on how I drive and if I use Charge Mode to force ICE.

1) There is ZERO ability (none; zip; nada) to use singular UOAs in such a manner; expecting to decide if one is better or worse than another. That is a fool's errand.

2) The engine does not have nearly enough time on it to have fully broken in;

3) Until break-in has subsided, you cannot reasonably understand if extending the OCIs is warranted or not

4) Hybrid drivetrains do not always demonstrate the same info as ICE when it comes to UOA data, because of the unique run/stop nature of the hybrid

1)I guess I'm a fool then since I'm awaiting UOA on a 6k mile run on Ravenol 0W-16.
2)Currently at 18k+ hard miles.
3)I did my best to follow1k mile break in after that I drive it like I stole it.
4)Agreed

What you are doing is a noble but premature experiment. This engine is still breaking in and Blackstone said as much. Run the Ravenol 6k as planned. Get a UOA if you care to. It is unlikely that anything you see in those three UOAs will be relevant over the long term.

Repeat your experiment after the vehicle exceeds 25k miles if you care to. Keep in mind that single data points have essentially no statistical meaning. Were you to run 3 x 10k miles on "oil A" then another 3 x 10k miles on "oil B" and see differences in wear metals that might say something. If you were then to go back to "oil A" and see the wear metal numbers go back to where they were then that would say a lot.

BTW - it is admirable the way that you researched and purchased the Idemitsu oil. You obviously want to show this vehicle some love.

Based upon extensive relevant personal experience, you should be fine with any of the 0W16's Idemitsu, Pennzoil Platinum or Ravenol EFE.

I used EFE in a 2012 PriusC with several ~10k mi OCIs.

I used PP in a 2019 Lexus UX 250h for a little while, again with ~10k mi OCIs (same engine series as your RAV4).

Unless the RAV4 is only short tripped in cold weather or else it is towing, this engine is well protected on quality 0W16.

Have fun by geeking out on the different oil designs !

Thank You! I'm already itching to try some boutique 0w-16 if the Ravenol 0W-16 didn't hold up according to UOA.

Hybrid ICE’s cycle a lot which can lead to condensation and fuel dilution. Also they tend to run colder. Mileage and time IMO isn’t the hybrid ICE’s main enemy it’s operating condition.
