5W30 In ‘20 Corolla 1.8L ?

[Patman]

Because Toyota and Honda are riding on their legacy from the 90s to early to mid 2000s. New age Toyota is garbage. Timing belt era Toyota is best. The Toyota 5.7 isn’t as good as the 4.7. The Toyota 3.5 v6 isnt as reliable smooth and quiet as the 3.4 and 3.0. And I know for a **** fact the new tundra twin turbo isn’t as good as the 2uzfe era timing belt engines

There are plenty of high mileage Toyotas and Hondas built after 2010, so I don’t think they have lost that reliability factor at all, other than a few rare occasions. My 2016 Civic has been dead reliable since I bought it with 80k on it three years ago, now I’m almost at 150k. And it hasn’t cost me anything in repairs.

900,000 miles on one of those 5.7 V8 engines. Not too bad.

The ‘20 Corolla 1.8L non-turbo owners manual states to use 0W 20 oil with no other oil weight options listed . Are there any special engine requirements (VVT , etc.) for the ‘20 Corolla 1.8L that would prevent a 5W30 synthetic oil being used ?

Go for it, my Kia is recommended 5W-20 on the oil cap I put 5W-30 It goes super smooth and quite since the better oil clearance.

Watch out for the grammar police. Quite or Quiet?
BTW..... if you have a 2020 or older Kia TGDI four cylinder, 0w/5w40 are what's best for that engine.

Out of warranty Toyota 1.8?.... use whatever gasoline-only engine viscosity / grade you desire.
Leave the diesel oils on the shelf at the auto parts stores. They are not what's best for your Toyota.

Stupid Question : Do the majority of Toyota Dealers use Toyota Genuine Motor Oil for serving their vehicles ? Toyota has a reputation for having a very good quality synthetic oil .

I realize this is a few months old. In March, I was on business in Florida so stopped in to see my Mother-In-Law for a couple of days before heading home. That morning, her neighbor helped her drop her 2007 Camry off at Toyota dealership for an oil chnage. As soon as I got to the house, she jumped in my car and I took her to go pick up her car. I was chatting with the service guy and asked him what they use. Answer: Conoco Phillips oil. I think they make Motorcraft oil for FORD and stuff like that. I also think it was just a semi-synthetic. My MIL had gotten a coupon. Oil Change deal was like $29. I told her I would do it for her, but she is pretty independent.

Yep Toyota has taken a Big step down that is why there is a Mazada in my driveway now. Previously I had owned 2 Toyota's for 27 years,

I am not fretting purchasing my new Rav4 Hybrid in 2023. Its all about numbers in manufacturing. I have total faith in Toyota having the 2.5 G-Force Hybrid engine in my vehicle. Nothing more --- nothing less.

I've been using 5w30 Supertech synthetic in my 2012 Corolla since new (almost 12 years now). No issues, didn't expect any.

11 years ago the engine blew up ,, you haven't noticed it yet !

5w30 is fine. Other country's manuals even allow for 20w50 for that engine.

I have seen many such statements on this site, about manuals from other countries. My search for a manual from another country has been fruitless. Where do you look to find them? I'm looking for a manual for a 2008 Honda Civic from outside the USA.

It doesn’t really matter. No engine is harmed with a higher grade whether or not it’s recommended elsewhere.

5W-30 is the optimal viscosity and would be used in most vehicles if CAFE fines didn't exist.
The rest of the world specs cars for 30 weight 40 weight oils.

For what it's worth, I'm getting 40 MPG on a 2008 Toyota Corolla on the highway if I drive with a light foot going the speed limit.
I'm using 5W-30 with normal tension piston rings. The engine doesn't use a drop of oil in between oil changes (likely due to the normal tension piston rings).

I don't understand the rush to low viscosity oils and low tension piston rings in the newer cars.
You can get great fuel economy without that using the simpler older tried and true technology.

An engine that specs 9.29 cSt will instantly self destruct if 9.30 cSt is introduced. It's almost as catastrophic as doing a Honda's first oil change before the Maintenance Minder hits 15% Oil Life.
