Engine oil for LS430
Hello Lexus family,
What engine oil would you recommend for LS430 2001 for weather temperatures reaching more than 43C in summers?

Almost 110F?

Removing engine heat should be a priority.
Engine cooling is limited to rise above ambient temperature. (System can't cool below outdoor ambient temperature)
If you do not already have OEM heavy duty or "tow package" radiator, then consider installing one.
Also consider application of thermal management materials to intake components.

0W........?
I'm interested to see any legitimate data supporting this recommendation for extreme heat climates. The OP is in a region where it will NEVER fall below 80 degrees F during the summer months. Any benefits from using low "winter" weight numbers as part of a multi-weight oil are basically null and void.

Would using 20W-50 Castrol GTX a good choice for such harsh weather?

I believe the Owners manual say 20 W 50 but also 5W-30 is preferred for all weathers ,also make sure you use 5W-30 full synthetic oil these engines are built very tight and have tight tolerances

5w-30 from major brand like Castrol, Pennzoil, Mobil1, etc - use full synthetic and change oil and filter at 5k intervals in that harsh environment. Use a high quality synthetic filter material filter like a Fram Ultra or NAPA Platinum filter. Be sure to use a high quality engine air filter given all the dust in the air and inspect and change it regularly.

Just read the owner's manual to answer questions like this. See pic from owner's manual below: 10W-30 is recommended if your LS430 will never see temperatures below -18C (0F). Otherwise, 5W-30. Both need to meet API SJ, SL, or higher specifications.
Direct quote from API: "If an automotive owner's manual calls for an API SJ or SL oil, an API SN oil will provide full protection." Name branding is just marketing, try not to fall for it. See https://www.api.org/products-and-ser...s#tab-gasoline and https://www.oilspecifications.org/acea.php and https://www.acea.be/news/article/ace...st-2018-update
Some oils meet more specifications than others - the brands that meet more specifications produce better oil and/or have enough marketing budget to pay for extra certification processes. Other specifications aside from API and ILSAC include ACEA, Chrysler 6395, Ford WSS-M2CXXX, GM dexos1, GM factory fill, GM service fill, BMW Longlife, Mercedes 229.#, Porsche A40, VW 502/505, Honda/Acura HTO, etc. However, don't waste your time getting caught up in this. Practically every major and minor brand will meet API SN and ILSAC GF5, and that is all you need to worry about (which is also exactly what the owner's manual says), so just pick the lowest $/L of 5W-30, synthetic optional, change oil and filter every 8000km and use the Toyota V8 filter, and find something else to spend time thinking about.

Best contemporary oil (year 2019) for ls430
Do Not use 10W-30...
Certainly Do Not use 20W-50.
Both oils exhibit poor cold start attributes (when most engine wear occurs)
To understand why, read the link provided...
Best contemporary oil to use: 0W-30 synthetic....
0W-20.lacks necessary shear strength at operating temperature. (If it means anything, that is what Toyota uses in newer models...what is used for EPA MPG testing goes in the owners manual)
If you choose not to read the link and are hung up on 5W-30 because that is what is contained in a 10+ year old owners manual, then go with synthetic.
Certainly Do Not use 20W-50.

Correct, I showed what my Canada/US owner's manual says. That's why my first sentence said "Just read the owner's manual to answer questions like this." So if you live in the GCC, get yourself the owner's manual that came with the LS430s sold in the GCC. Australia, Europe, and US/Canada also have different manuals and specs. Lexus provides these manuals for free on their official website, as well as on the TIS website for free.
