You don't need a Restore and Protect product if you run decent oil in the first place. See my post above. UOA for the entire life of 2 cars is documented here on Club Lexus. I have the data and it's posted for all to see!
Higher Compression, smaller/fewer Cylinder Bore size, heavier vehicles, Turbo charging, and all of that points to the weakest link: Piston Rings.
Keeping those rings as clean as possible is critical in 2024.
Restore and Protect has been engineered for that specific purpose.
Vehicle owners have been sucked into the OEM BS that is focused on the Leased Vehicle owner.
10K oil changes on this combo:
Lexus LX550 has a 6 cylinder Bore Size of 86mm.
It curbs weighs 5,900lbs and tow rated for 8,0000lbs.
GoBose, please stop with the multiple replies, do it all in one post vs continuous responses. I've merged your last 3 sets of posts.
To everyone in this thread. If you've already made your perspective known (or in some cases made it repeatedly), no need to keep stating the same thing over again. Consider you've been heard and don't be repetitive. Let's keep this discussion focused on the RX please.
What? People have opinions and this is a forum about opinions.

Now I'm being threatened? For being "repetitive"?
I'm not adding, I'm responding.
Weird.
You're responding with your opinion post after post after post after post. We got it. Enough already.

Not threatening, I asked some very simple things of you to increase the usefulness of this thread and to respect to other member’s time.
Going to ask you one more time and I’ll explain why since you seem to be ignoring me with your subsequent replies
You reply in a serial fashion one post after another where you can just do it in one single reply or multi quote. You keep bringing up other vehicles not the RX.
Not only is it difficult to read (and often repetitive content), there are already 333 posts in this thread, many other members get an email or pm notification for every reply. They don’t need to get dozens of emails daily, one for each of your replies. And if it says the same thing you’ve already said in past posts or about a vehicle not a RX that is even worse.
I’m not asking for no reason. If you want to discuss further pm me and let’s get this thread back on topic.
You know that reminds me of Clark Stanley in the 19th century. Until he got investigated and were shut down by the feds.

And what are those specs? Lexus does not share these proprietary data with 3rd parties unless they are a parts supplier for them, and they are not.
There is a difference between facts vs assumptions. Just like how you assumed physics instead of tribology which is a superset inclusive but not exclusive of physics.
The oil gets dirty regardless of the difference in filtration. It’s not like the Toyota filter has holes which lets metals though to grind out the engine lol.

Reason: Multiple posts. Come on

"dirty"? What do you mean? Above 20 microns or below? "Dirty" is a fact?
Oil Pump Pressure specs? What is it? Your engine light will come on if its out of specs. Super simple. Are you joking?
Anyone have suggestions for a premium oil filter? Definitely not royal purple. I bought one that showed up looking like it was pulled out of a factory dumpster. Facts

Well - not happy with this design at all. I dropped the plastic canister and it pretty much exploded. The good news is that I actually had purchased a spare because I
figured the plastic would break and then I would be stuck. However I found this spring in the parts on the floor. I can't tell but it looks like the new cap doesn;t need the old spring. Is the spring needed and where does it go?
Really? What is?
You throw out that statement but don't back it up with anything.
Pennzoil Ultra Platinum is running $36+.
How much are you saving under $26 from a name brand oil?
Walmart brand? Doesn't count. At 2.5K, its ok.
But this Valvoline Restore and Protect has been specially designed to remove piston ring deposits.
No other oil offers that particular, focused, capability.
Watch my Youtube post on Car Care Nut, and what piston ring buildup will due to a Toy/Lex engine at 100K with 10K changes.
Don't forget a Royal Purple filter to trap that sub 20 micron particulate matter.
I'll run 2 oil changes with Valvoline and may then switch to Costco or Walmart at 2K - 2.5K changes.
Good idea.
I went with the testing results from the Youtube video I had posted.
It's excellent because they factor in both Flow and Filtration.
In their tests, Purolator Boss was the best.
RP had better filtration but lower flow.
A classic, physics issue: Flow vs Filtration.
They work against each other.
Their Top of the Line 0W-20, "Advanced Full Synthetic, High Mileage" states 20K oil changes.
Absolute, rubbish.
I have no intention of using their oil when they market it with such nonsense.
Honestly, does ANYBODY on this forum believe that?
20K miles. They're lying to you.
That is 100%, going to create sludge in your engine.
Why does Walmart have such a following? 90%+ of what they sell is made in China.
You want to debate about oil?
Go on bobistheoilguy forum and it will open up your mind.
There are tons of oil analysis threads on there you can check out for evidence.
There is such thing as "best" oil. The best would be the price. Especially when you are changing it before 5K miles.
There is no synthetic oil going cause performance issue especially when changing before 5K miles.
There is no need to argue further beyond that.
These 2GR engines are not picky about oil, so you are really overthinking this.
GoBose drop the personal & rude commentary or exit this thread.
Already asked this both publicly and privately, you can disagree without the name calling. Stick to the filters

Keep the discussion on the topic of the maintenance schedule including filters and their relative benefits please, not on the people who may have a different opinion.
