Anybody using 5w30/0w30 instead of 0w20?

Except for the fact that I am a mechanical engineer and have better than a fair knowledge of direct injection internal combustion engines.

 

no, and that is why Suave is incorrect in his presumptuous statement.

 

Owned a 2.7 since new (2007)
First 5 yrs (100000kms) went to dealer for every oil change.
Last 10 yrs (192000kms) I put whatever is on sale at Walmart in
(I'm a cheap bastard) 0w20 5w20 5w30
Never noticed a change in mileage
Uses about 1 litre every 10000kms
Always change oil with a denso filter (rock auto) every 10k

New 2022 on order. Back to dealer till warranty is over

 

What production year are these for?
I've only seen the 2018 for the Kluger.

 

lol, I have no idea. I didn’t design the engine

 

mechanical engineer/design technology major here ……gonna be honest. Just like I said above. I didn’t design the engine. I trust a company who has made billions of reliable cars. Just me. Do as you wish. I can’t control your vehicle

 

I’m wrong for trusting the people who designed and tested the engine? Okay. You do you, boo boo

 

So the 2gr-gks in the US is a completely different engine than the 2gr-fks sold in non-us markets?

If so, that would explain the difference in oil "preferences".

I say preference because that is the wording in the manual.

 

Got it from here - for a '21 model

Please read my previous posts . I didn’t design the engine I have experience with engineering, but I won’t claim to know how an specific engine works. I’ve been working on/rebuilding/ racing/ beating on cars for 25 years. Never had an issue with manufacturers oil guideline’s.

I’m sorry, you guys are trying to argue on this, and I don’t know why . Do what you want. It’s not my vehicle. I gave my opinion based off of what I know….just like you. If it runs perfectly, FANTASTIC!!! Me personally?? I will be running what Toyota has in the manual

Edit: I’ve owned 2 cobra’s, 2 84 5.0’s, 3 m3’s, WRX, FRS, 3.6R, and now the Tacoma.

 

Here's what it says in the 2018 Tacoma manual regarding oil:

“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: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is 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 must be replaced
with SAE 0W-20 at the next oil
change.

 

Valid point. Wouldn't be the first time that Toyota used the same engine code for two motors that are different in the US than the rest of the world. Hell, they use the same engine code for the 2JZ even after they started incorporating VVTI into it.

Another engineer weighing in. I have not seen any research published on the effects of different oils on this specific motor. Until I do, or I have the salary to piss these things away, I will follow manufacturer's recommendations - if only for not voiding the warranty.

 

0-20 in warranty. Out side of warranty run what’s best for your climate

 

10-30 has been working great in mine every summer never noticed any gas mileage change & two oil tests in 70000 miles done by my local caterpiller dealer have come back perfect. I do however use 0-20 in winter due to -40 temps (my diesels get 10-30 in winter)
If I still lived in Vegas I'd seriously consider 15-40 in my taco just because hot 0-20 drains from every internal surface after shutoff into the oil pan & im positive if for just a milisecond every time you start it for the first time next day there's NO oil pressure causing engine wear

 

The “0” in 0W-20 is the cold viscosity. You need that for variable valve timing lubrication. Don’t mess with that.

 

I like this post in that thread better

What problems are people having with 0W-20, why would you want to use anything different?

 

Hard to find & twice the cost

 

I haven't had any problems finding it, Wal-Mart always has it.

 

You don't live in Jackson hole Wyoming & wall mart is 200 miles away
