^^^ post of the day
100% agreed on all points... car is not being driven like a formula 1 race car.
i've only had 1 oil change so far (free, at dealer, and they put in synthetic ) so haven't had a need to change it on my own yet. but i likely will when it comes time (after next change). i've done it on some of my other vehicles.
how hard do you find changing the oil on the LC?
i've used a fumoto drain plug/valve on other cars because it makes draining the oil so much easier and not messy. recommended.

What I find a little confusing about this discussion, is that the badge under the hood only says 5W30, and nowhere in the manual does it say, you need to use conventional oil.
I believe, the manual would state that only conventional oil should be utilized if it was a mandatory requirement. It does say, that the oil that is being placed into the engine, needs to be a certain weight as well as meeting certain quality specifications. Whether the oil is synthetic or conventional as long as it meets or surpasses the denoted requirements, either really should be fine. Further, as I posted awhile ago, a master technician at Lexus advised me that one could absolutely use synthetic oil in an LC. I feel, it is a personal preference. I use synthetic in my LC, and believe it is the best way to go for protecting the engine and that offers me a little bit more peace of mind.

The point is that Lexus service recommends conventional and the new car comes with conventional. No one said the label in the engine bay says conventional oil required.
I may convert to synthetic after I hit 10,000 miles.
The other issue is that if you look at the You Tube video, is you don’t know what oil the Lexus dealer actually uses. They buy the cheapest bulk oil possible and self oil changes is the only way of actually knowing what brand of oil you get. Regardless of the conventional/synthetic issue.
i think the oil brand is actually a bigger issue than if the oil is synthetic or not. With a dealer you don’t know what you are getting.
When I had my BMW 550 and my BMW dealer was changing the oil I am certain they were not changing the filter for several changes. When I went to do my first self oil change the filter was extremely dirty and crushed from over use. Can’t prove it but I’m certain they skipped changing my filter and this was a high end BMW dealer.
I hate letting anyone mess with my car unless I’m watching.

A number of people who posted here were convinced that we absolutely needed to use conventional, and this was a big part of this particular thread's discussion. I may have missed this somewhere within the posts, but how do we know that the engine comes from the factory with conventional?

^^^^Because the Owners Manual says it does. See my post #30 or read the first sentence below:
Hard to believe that this thread is almost one year old thread is still being discussed
And to throw a monkey wrench into this discussion I do not use 5W30 I use 10W30 - Why you ask Well because I've been around a long time, done a lot of reading and still do some minor maintenance on my vehicles. 5W30 is an oil made to run thin at startup, the 5W label. 5 meaning the oil weight at startup and the W meaning winter. The oil thickens up as it warms up to become a 30 weight oil. Since I live in a temperate climate and never experience temperatures near freezing I don't want or need such a thin oil at startup. That's my thinking process and I've used it with success for the last 50 years since moving from the NE to the SW.

Does anyone know what kind of TGMO the LC is filled with at the factory? TGMO is available in both mineral and synthetic
the oil grade referenced above in the manual seems to have a lot of synthetics
https://pqia.org/2020/10/21/motor-oi...etail-shelves/
I wonder if blackstone or a similar service can tell from their testing, I know they ask you if it is when you send it in so guessing they don’t with their standard testing

^^^^From what I see at the "Toyota Parts Center Online"
https://parts.toyota.com/go/Genuine-...ce-Fluids.html
TGMO Synthetic only come in 0W-20. Dino comes in 5W-30, 10W-30 and 10W-40.

as riotgrip said, these cars are hardly taxed so i'm sure there's lots of 'right' or ok answers.

Is Lexus recommending different viscosity oils depending on climate? All I saw was that 10w-30 could be used if that’s all that was available but needed to be replaced at the next service. Looks like Lexus recommends 5w-30 for all climates. Synthetic vs Conventional is one thing, but changing viscosity is a whole lot more significant in my view.

Reading this thread because I was perusing the LC forum and I was surprised to read in this thread that Lexus lowered the sump capacity for the LC500 to 9.1 qts 🤔.....why do you guys think they did this compared to the ISF @ 9.8 qts? Don't know for sure if the RCF/GSF/IS500 take 9.8 or 9.1 qts?
