ANOTHER OIL THREAD (Actual information doe)

[concept]

I disagree. New government regulations drives requirements for thinner oils. It's a cheap way to make fuel consumption targets. If heavier weight oils were being usurped by light weight oils then heavier weight oils would be disappearing from the mainstream market which they aren't.

You may want to check out "The car care nut" youtube channel. Ahmed, a Toyota master technician and owner of an independent shop created a video in which he explains reasons for thinner synthetic oils. One is an oil pump system that monitors oil pressure and flow. A thicker oil would eventually prevent it from working properly. Lake Speed recommends that having your oil checked is a good idea. I believe that Toyota is the last company in the world that would not thoroughly test oils that they specify. Their reputation may occasionally take a hit for other reasons, but their introduction of 0W-20 synthetic oil, 15 years ago has been cause for premature engine failure. Most youtube channels, including the car care nut show too long oil change intervals as the main culprit for engine failures.
I also maintain that if oil analysis at your Supra's drain intervals shows that everything is good, then there's no reason to change whatever oil you are using.

Your absolutely right that Toyota thoroughly tests their oil they specify, but why does Toyota only spec 0w-20 for the GR86 in the US but in Australia they also spec 5w-20 and 5-w30 for the same car with the same engine? Does oil work differently in Australia then the in the US? Toyota even says to use 0-w20 just for better fuel economy and easier starting in the cold but if the car will be subjected to higher speeds the extreme load then to go with a higher viscosity.

Please tell us more about your 1988 BMW.

I honestly have no idea why this just fucking continues and continues and continues and continues and continues and continues , especially with so much explicit documentation from the actual manufacturer that has been shared.

Us:

"Here are multiple explicit documentations from the actual manufacturer..."

Them:

"yea but, did you see this influencers youtube video?"

"How about the info I got from this third party company that sells competing oil?"

Idiots just double down on their moronisms.

I’m giving this phenomenon a name… The Boomer Blob. So many threads anymore get slowly and irreversibly taken over by it. It’s indescribable… indestructible. Nothing can stop it.

I've asked this before but no one has answered: What does BMW specify for oil viscosity and certifications for their Z4 3.0 sold in the US?
Every time I search, this is what I get:
For the BMW Z4 with the 3.0-liter B58 engine (2020–2025 models), BMW typically specifies 0W-20 engine oil that meets the BMW Longlife-17FE+ standard. This oil is designed to provide optimal performance and fuel efficiency while protecting the engine under various operating conditions.

Also, does the saying, "Most engine wear occurs at cold startups." still hold true? If so, why would not a 0W-20 oil not be preferable for street-driven Supras?
RazorLab picks a high-viscisity oil for racing, so that must be the best oil for the average street-only driver? That makes no sense. What makes sense is that if I use 0W-20 oil with required certs, and find that periodic oil analysis shows little to no wear, why would I change?

Razorlab is being sarcastic. He hates those who contrast older car stuff with the Supra. He is the reincarnation of Doctor House who was the king of insults and sarcasm. (Well, maybe not quite as sarcastic as Don Rickles in CPO Sharky)

I love how an actual factual thread becomes full with shit. Lol

Quick question for the oil experts, I use a top shelf oil (Red Line) and when I change it I send the sample to Blackstone. I've have great reports back, so I think I'm using a fine oil for the car.

Anyway, I've been watching Lake Speed's channel recently and he was referring to having your oil tested new to create a base line which I get. My question is does anyone do this? I think it would just be an added expense to do so just to find out that the oil is fine, and probably has the additives that the manufacture calls out on their website. Anyway since the topic is hot right now I figured I ask the question!

If all you are doing is driving around wearing jorts and white New Balance sneakers and not pushing your Supra then 0w-20 will probably be fine.

So I guess if I wear gen X, Y, and Z clothes, 0W-20 oil just won't "cut it"? I do know quite a few 20 - 42 year old Supra owners. I guess I'll make sure I don't dress like they do.

For the sake of a legit discussion, and not to prolong any agonies, it is this. I have the sticker on the underside of my hood saying as much.

in Australia they also spec 5w-20 and 5-w30

That's a good find. I've tried to see what was used in Europe for the Z4 but no luck.
