Entertaining oil commentary and recommendations from social media

[TiGeo]

This one have me a laugh. This is for a VW MK7 GTI that is a track car (not a daily anymore). She states she went up a grade to a 10W-40 from what I presume was a 5W40 Euro VW502 oil. She also states this dropped her oil temps 20 deg.

Firstly...aren't most 10W40s lower quality oils vs. a Euro 5W40? Many aren't even "full synthetic" correct? I usually think of 10W40 as an old-school oil for old-school vehicles...not something I'd use for track use vs. so many other better choices.

I don't typically believe anyone that states wild drops in oil temp without before/after datalogs with similar conditons maintained for both but is it possible that the HTHS of the 10W40 stuff is lower than the Euro oil which could lead to this?

I realize "the mechanic" is likely thinking a 10W40 is thicker than a 5W40 due to a lack of understanding of winter rating/grade which we all know is a thing ("0W is like water bro") and that's what the recommendation was based on.

Edit. I could probably keep this as an ongoing thread as I'm active on many FB groups where folks post some questionable oil-related things regularly.

And folks wonder why I don't have anything to do with social media .

Unrelated to your post above, but on the reddit Civic sub, one day people get downvoted for not following the Maintenance Minder, and the next day everyone is saying change the CVT fluid at 30k miles. Which way is the wind blowing today?

“Bro this 10w-40 is so thick. Never using that watery 5w-40 again bro…”

Full send on anything you got - keep them coming.

Every now and again I stick my nose into the fray on FB for something like this. I then get told how superior X is and Y caused my engine to blow while Z was cheating with my wife/gf.

It's good for a laugh.

The things I have read on Facebook.

FB is weird--whenever I try to look up something, either marketplace or a local business, it will let me surf in for a minute, then wants me to login. Which is impossible as I don't have a login.

Yet the other day I found some enthusiast page for, of all things, lovers of putting steel rims onto cars. ? First, I didn't know that was a thing, and second, FB was happy to let me scroll through that.

Not completely convinced that I want to sign up. But maybe it'd have more humor than LinkedIn?

That is actually possible. However, they usually forget that that day it wasn't 100f but 60f, and there was traffic, so could not push to the limit, and they had heat on which helped cooling etc.

They are usually Group III (not talking HPL, Motul 300V), and Group II. Higher KV100 to bump HTHS, a lot of shearing.

She should ask the mechanic how much track time he has.

Is it though? Well it HAS evolved from strictly forum format over the years to more social media-like, BUT, it had not devolved into the mindless time-suck that will be the death of humanity like FaceBook, Instagram, X, and all the other drivel out there that fosters insanity. Oh, forgot to add "trigger warning" to the beginning of my statement .

 

[Hall]

Is it though?

Yes, much to the dismay of many (who feel it's a stamp of pride that they "don't do social media" or "don't have a Facebook"). It fits perfectly into the definition of social media too, plus we have posts about the food people eat, TV shows, etc.

Yes but was the oil gentle.

On the JL forum years ago someone swore they had lost something like 3 or 4mpg just by going from recommended 0W20 to 5W20.

I told them there was no way and just got the typical digging-in-the-heels of "I know what I experienced." OK (shrug)
