Notice new Corvettes no longer have Mobil on the cap?
You're right, I'm wrong. I know nothing about these engines.

running mobil 1 in my car when the oil temp hit 200 degrees, at idle I was at 13psi. I swapped it out to amsoil and now I get 20-23psi at 210 degrees oil at 550 rpms. same weight, only difference was running a better oil that had a better filming index or whatever thats called.

Not saying that at all...but M-One is only as good as it has to be. I've used it at times, and don't hate it, I just have better results with Amsoil and RedLine (Which I can no longer afford)

As we all know, the recommended oil for the C5 in 1997 was the Mobil 1 5w30 Synthetic.
Since then (20+ years ago), oil technology has come a long way, and Mobil 1 0w40 (European Formula) Synthetic has better proven cold start protection at a 0 weight when cold (where 90% of engine wear occurs), and also has a higher HTHS rating designed for better wear protection on motors that run very similar temps to the C5, such as many BMWs which run in the high 200 degree range.
Now, 20+ years later, if the Corvette engineers tested the LS1/LS6 again with more modern oils, I bet they would change their recommendation on what oil to use.
You can read everything you want to know about oil (or ask questions) at the forums at https://bobistheoilguy.com/forums/ub.../forum_summary
The oil nerds there know much more than we do here on this forum about oil. Over there, forum members have also posted the oil analysis results from Blackstone Labs for people running different oils on LS1 or LS6 motors (Google search "LS1 site:bobistheoilguy.com" or "LS6 site:bobistheoilguy.com) for easier finding of info.
Read about HTHS ratings here:

Mobil 1 spec sheet (note the 0w40 has a higher HTHS rating of 3.6 versus 3.1 for the 5w30 which means better wear protection at the negligible expense of slightly lower fuel economy): https://mobiloil.com/en/motor-oils/mobil-1/mobil-1

Safe to say the turds I flushed this morning knew more than you do about Corvettes (intricate mechanical details of all generations).
Ignorance is bliss they say, I bet you're enjoying the ride.

Mobil 1 is factory fill for Porsche. I guess Porsche just puts garbage oil in their cars because they got paid by Mobil ?
You're the ignorant person saying crap like Mobil 1 is garbage, with absolutely no facts to back up your claims. "Hurr duh everyone in the shop knows it" GTFO with your BS.

I'm not even claiming Mobil 1 is the best, or that other oils aren't as good. The truth is anything that meets spec is "good enough". There are C5s with 300-400k miles that used nothing but Mobil 1. Engine failures due to using the wrong brand of synthetic oil is pretty much unheard of.
Claiming Mobil 1 is garbage because they like another brand of oil better, is just ignorant hyperbole.

Actually Mobil is complete garbage. It's a running joke around the shop. Stuff gets thin as water when hot. Makes the engine noisy. We only keep one single oil change worth out of a near mountain of oil we keep just incase a ding-dong insists we put that **** in their engine.
Personally in our own cars we run Amsoil or Castrol Syntec.

Guess what? You don't work on over 2000+++ Corvettes each year.
How many is that per day that pass through here? Probably the busiest Corvette-only repair shop in the universe.
But.... what the entire shop says is nothing right?
Enjoy your opinion, and the junk you're pissing into your engine.
-later
p.s. Had to redo the math, it's well past 2000 per year. But, I'm sure that doesn't matter at all to you right? You know best.

Never claimed mobil 1 is garbage or amsoil is better, I only stated that at higher temps my mobil 1 turned into water and gave me lousy pressure, I even used royal purple and even castrol euro brand and got much better pressure about the same as the amsoil. I tried several different brands and my conclusion from my testing was I no longer use mobil 1 due to the loss of pressure at higher temps.

I remember Amsoil was kind of a big deal back then even though they didn't have a giant like Mobil behind it.

FACT: Oil companies make deals with auto-manufacturers to sell oil products. The engineers designing the engines didn't design the engines around Mobil 1 engine oil. Audi has a thing for Castrol, Porsche has a thing for Mobil 1, Chevy has a thing for Mobil 1. The fact that "Mobile 1 is the factory fill for Porsche" means nothing lol. All it means is Porsche can stock-pile Mobil 1 products for its customers.
Do you have to use those oils? No. You're using synthetic oil in 2018... it doesn't matter who's name is on the damn bottle.
