Toyota 0w-20 Motor oil, how good?

[wooferocau]

I have just purchased a 2026 Toyota GR Corolla. The dealer will use Toyota 0w-20 motor oil at the service intervals. I was going to ask them to use Amsoil Signature Series 0w-20 but not sure how that "may" effect warranty.

Question...
Who makes the oil for Toyota? Is it a decent oil?
Thanks..

Mobil. It's fine.

I wouldn't use it in a high output 300hp 3 cyl. It's basic 0w-20 made by mobil but if you don't drive it too hard it should be fine. Change it every 5000 km or half a year or sooner.

My 2016 Lexus es350 which now has almost 108k miles has been running on Toyota genuine 0w20 since brand new. It got oil changes at the dealer every 5k miles religiously from the previous owner since day one.

The inside of the valve cover is spotless. Zero varnish, no sludge. Engine does not consume any oil or leak any.

TGMO 0w20 is made by Mobil 1.

My local Toyota dealership has the 0w20 at $3.86 per quart. It’s an amazing deal, but I’m going with Mobil 1 ESP 0w20 on my next oil change.

Good enough for most Toyotas.

Does your manual, like most Toyota manuals, say that you can use heavier oil in heavy duty exploitation scenarios?
If so, run Mobil 1 ESP 0W30.

No ... It spec,s 0w-20 only..

I would run 0W20 that Toyota wants, which would be API SP I guess. You don’t have to run TGMO.
After warranty, move to Euro approved oils, particularly MB229.5 or MB229.51/52.
Toyota will bend backwards to refuse warranty. They refused warranties on those Corolla’s bcs. they were driven above 85mph.

Tgmo has very high moly....that will keep your timing chains happy.
I thought tgmo was highly regarded around here.

I think moly dropped to average levels in TGMO.

look for the manual in UAE or somewhere other than USA.

Nothing special.

Noooooooooooooooooo

TGMO 0w20 is made by Mobil 1.

That statement is not quite accurate. TGMO is an Exxon Mobil product but it’s not the same formula as Mobil 1. It’s a completely different product. A lot of Toyota owners mistakenly believe that it’s Mobil 1 actually.

Here's a link to the Toyota of Mexico website: https://www.toyota.mx/propietarios-...-tu-auto/#tabs-6478e6d6a3-item-2fa521cc7f-tab and the Toyota website in the UK says, "

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy the following grade and viscosity. Oil grade: 0W-20, 5W-20 and 5W-30: API grade SP “Resource-Conserving” or ILSAC GF-6A multigrade engine oil. Recommended viscosity (SAE): SAE 0W-20 is filled into your Toyota vehicle at manufacturing, and the best choice for good fuel economy and good starting in cold weather. If SAE 0W-20 is not available, SAE 5W-20 oil may be used. However, it should be replaced with SAE 0W-20 at the next oil change."

This here.

I was waiting for that.

 

[edyvw]

I was waiting for that.

I don’t see reason why not using SS or ESP 0W20 under warranty.
After that, whatever.

I wouldn’t see a reason not to use ESP 0W-30 under warranty. But whatever

Yeah. Not sure how diligent are they with warranty. I mean, they refused warranty for driving above 85mph in performance vehicle.
