0W-08 Engine oil

[Bill7]

There is no such thing as a 0w4 oil

I really respect Toyota and their long track record of unsurpassed reliability, but their specing new Corolla's and Camrys for 0W-8 is a little too extreme for me. 0W-5 exists. AEHaus has a thread where he put 0W-5 into a Lincoln Navigator that was speced for 5W-30.

At the rate Toyota is going, I'm afraid the next gen Corolla and Camry might be speced for 0W-5.
To Honda's credit, at least they stopped at 0W-20 (except for some Honda Fit's which are speced for 0W-16).

It's sold in 1 gallon cans that say WD-40 on them. Squirrels on YT have actually ran it for engine oil.

2008 was the last sane year of the Toyota Corolla. That year's Corolla is speced only for 5W-30 for all temperature ranges in the owners manual. In the owners manual and dashboard maintenance minder light, Toyota recommends 5,000 Mile / 6 month OCI (not 10,000 mile OCI). It uses screw on oil filters (not cartridges), normal tension piston rings (so no oil burning), bulletproof engine and transmissions that several forums say you can drive it 300k miles. I'm getting about 40 MPG on the highway.

I'm getting 40 MPG with 5W-30 and normal tension piston rings in my 2008 Toyota Corolla.
I'm not understanding the need by Toyota to go to 0W-8, on these new vehicles. Could a car speced for 0W-8 reach 300,000 miles on the original engine? Time will tell.

Did you happen to miss that @DirectRejection is already well past the halfway point to your measuring stick using 0w8? IIRC this is even being done in an engine that recommends 0w16.

DR, what’s your mileage total now, and is the 0w16 factory recommendation correct?

0w5 does not exist either. That’s just a made up viscosity by those oil manufacturers and in reality they are actually 0w8. But in terms of an SAE classification, the lowest one is currently 0w8.

I live so far from civilization, and my daily commute to the park and ride puts over 20,000 miles a year on it.
Longevity is very important. I only want to buy and drive vehicles that can make it to 300,000 miles with minimal repairs.

With 0W-4, I would be lucky if it completed a 150 mile roundtrip commute for 1 day before the engine blew.

Proof the engine wouldn’t last 150 miles? Or is this just pure conjecture with no actual basis to any claims of truthfulness?

It’s starting to sound like the early 2000s again, when naysayers all said that Ford and Honda engines would be failing all over the place on 5w20. I’m still waiting for that to happen

Here are a few other discussions on this topic.

Your friend should not switch to an 8-grade unless the owner’s manual lists it as acceptable.

I've been thinking about using 0w-16 HPL Premium Plus in our 2017 Prius V that is basically a grocery getter. Occasionally it gets a long highway trip but never in 90+ ambient weather.

2022 Corolla Cross was traded in at 140,290 miles.

New vehicle is a 2024 Corolla Cross Hybrid. Factory fill was replaced with HPL PP 0W8 at 304 miles. It was changed at 29,488 miles. Currently I am at 44,486 miles on my second OCI.

0W16 is the spec'd fluid on both vehicles.

0w20 is for your 2017.
The BITOG Saying is a little thicker grade (5w20 / 0w30 / 5w30) is the norm as the vehicle ages. But never do the BITOG Oil Gods suggest to go in reverse (0w16).

0W-5 doesn't exist, it's a made-up grade, there is no definition for it under SAE J300. It'll end up being a 0W-8 or 0W-12 depending on where its specs align with the table. One of the "0W-5's" previously mentioned on here ended up being a 0W-20.

Why did you decide to use 0W-8 in that vehicle?

 

[DirectRejection]

Why did you decide to use 0W-8 in that vehicle?

It was based upon previous experiences with...

--HPL PP 0W8 in a 2022 Honda Insight (mild hypermiling, gradually extended OCIs & UOAs. ~20k total miles

--HPL HDEO 0W16 in a 2019 Lexus UX 250h ~10k mile OCIs no UOAs + 100k miles.

--Study of the engineering in this engine, wherein temperatures are well controlled.

--Decades of experience in my job as a delivery driver subcontractor in the San Francisco Bay Area (mildest of climates), logging millions of miles, with occasional UOAs, and clearly indicating that my circumstances are easy on oil.

--Discussions with David Ward.

--Reading about the bonafides of High Performance Lubricants.

--Knowledge that 0W8 was already spec'd in JDM Yaris Cross Hybrid.

Thank you for asking, as I respect your high end chops. The grade is significant, as is the extending of UOAs.

 

[JAG]

Thank you for the detailed answer and kind words, DirectRejection. That sounds like a well thought-out and tested decision.

 

[chrisgraham]

A friends 2.0 Toyota uses it. Boggles my mind. He is planning to switch to 0W-16. I suggested he go to 0W-20

Well, I expect 0W 0 is already under development.

 

[chrisgraham]

But you know BITOGers....need that thick oil to drive at <2K RPM to the grocery and back once a week at 5 under the speed limit with their turn signal left on....

Hey, I almost never leave my turn signal on! For more than 15 minutes or so.

The mentioned Red Line 5WT "0W5" was a much thinner KV100 and HTHS than a 20 grade. Looking at SAE J300, Red Line probably called it a "0W5" because of the HTHS viscosity, since the minimum HTHS for an 8 grade is 1.7 cP.

Vis @ 100°C, 4.6 cSt
HTHS = 1.58 cP

Thread 'Upcoming 0W5 Grade Red Line Oil Experiment- 2019 Lincoln Navigator 4WD 3.5L V6 Twin Turbo'

Jan 18, 2023

Engine: This Black Label version of the Navigator has a 3.5L, 450-hp twin-turbo V-6 pushing an over 3 ton barn door through the wind. It has 9k towing capacity and specs a 5W30 motor oil. It is mated to a 10-speed automatic transmission. The package gets you to 60 MPH in 5.4 seconds. Correct me if am wrong - I think the twin turbos are of different sizes to minimize turbo lag, a small turbo and a large turbo to better cover the RPM range more efficiently.

Test Conditions:
The car had around 28,000 miles when the 5 grade oil was put into it, 29,000 when I took out the oil. The oil filter...

It wasn't the Redline one I was thinking of, but I see I said the same thing in that thread, lol, about the previous examples, one of them was "Neo", I think there were a few others.

As you note, Redline can call this whatever they want because it's not a product that fits into J300, due to the HTHS being below the minimum required. The results in that thread weren't what I would qualify as a "success" either, hahahah

Good to know, thanks for the info. I have a 2025 Crown Signia Limited on the way, 0W-8 is called for, 0W-16 is allowed but recommended to replace with 0W-8 at the first possible opportunity. No other viscosities noted and no temperature chart. Free dealer maintenance is for the first 20k or 2 years and first dealer OC will be at 5k miles (per the dealer's instructions). I plan to do my own OC at about 1k miles, possibly go with HPL 0W-8, let the dealer change at 5K, replace with HPL for the following 10k until the next dealer OC and go with HPL after.

Beautiful car ! The maintenance will serve you well.
