Oil for Rav 4

[oilfan99]

Lol I bet Honda had some good mpg for the epa

See my signature line below post#22 (note: signature lines now appear only on the first post of a thread)

The only engine in our household over the past decade that ran well on spec'd 0W20 without engine developing a knock or loud clatter was a 1.5L in my Honda Fit Sport.

On a possibly related note, Honda now has huge issue on their hands with their V6's pounding out con rod bearings - Can't tell you at this point if it is primarily a customer maintenance neglect, defect, or design/spec as the root cause. Yes, it's not a Toyota, lol.

FOX Business News/Reuters: "The U.S. government's highway safety agency is investigating as many as 1.4 million Honda and Acura vehicles after complaints that the engines could fail. (by my simple calculation, using warranty claims, only 0.1035% of this group is affected; outside of the PT warranty period, one would expect there could easily be many more vehicles impacted)

The probe by the National Highway Traffic Safety Administration covers the 2016 through 2020 Honda Pilot and Acura MDX, as well as the 2018 through 2020 Honda Odyssey and Acura TLX. The 2017 through 2019 Honda Ridgeline is included in the probe too.

Documents on the website say that connecting rod bearings on vehicles with 3.5-liter V6 engines had the possibility of failing, which can lead to a complete engine failure. One owner even reported a vehicular accident.

A similar recall took place in 2023 when Honda recalled approximately 250,000 vehicles to fix similar issues.
The new inquiry does not include the same vehicles included in the 2023 recall.

There have been approximately 1,450 warranty claims so far according to the documents, but no reports of injury.
Dealers are in the process of inspecting the affected vehicles and repairing the issues as needed."

Wild, wild speculation here, but I’ve noticed that it is very easy to overfill the Honda 3.5 with oil. I wonder if regular overfilling and subsequent aeration of the oil could contribute to these bearing issues.

Overfill?....... or my guess is you meant to say topping off?

I mean pour too much oil into the sump such that it is over the fill line on the dip stick and the crank is bathed in oil.

If I am draining a sump at home and the volume in the drain tub looks "suspect" I pour it into a windowed jug I have saved, Just don't let them bulge out - to get a good reading. On the lift, they get a good draing then the book qty when back on the concrete - and on the way they go. If the vehicle is an unknown or specialty it will get a 1/2 lite under book then a top off if required - after a start and a 10min + sit. This practice is time consuming in a shop.

gp&ds, Have you serviced these V6 engines and noticed issues? Why is the level hard to read? I know subaru had been sensitive to tilt left or right. But this is a home driveway issue not a shop issue. - Arco

I wouldn't do 10,000 mile oil changes on any vehicle that does city driving. Maybe with highway miles I would. City miles are hard miles.

This whole thing re: 0w8 or 0w16 has been hashed over for months in various threads that pop up every day it seems.

Same thing happened when 20 grade became de rigueur and a bunch of folks said, "I am sticking with 5W30!" lol.

-Arco

Indeed they did. First the uproar of 5w-20, then 0w-20 a few years later.

I don't have a RAV4 but it's the same engine in the Camry Hybrid. I do 5k changes, I've "heard things" about going 10k. FUD I know but so far, nothing to report, after 90k (no consumption). Am still running 0W16 as the wife doesn't drive hard, but she pays attention to the mpg readout, and is annoyed after I drive it any distance.

I do find that it seems overfilled if I put in a full 5 quarts so I've been doing 4.5 and sleeping better at night. Annoying to have half a quart left over, but at a change every other month, it too does not keep me up at night.

My daughter is picking up 2025 RAV4 Trail in Jan, I plan on using M1 ESP X2 0W-20. Manual has a paragraph saying 0W-20 is allowed if 0W-16 isn't available but in following one says thicker oil is recommended if driven at high speeds or towing.

M1 ESP X2 0W20 = KV100 7.9 so technically the viscosity falls into both 16 and 20 ranges per J300. I wouldn’t worry about what the manual says regarding viscosity cause the engine won’t show any noticeable difference with this application.
