Higher Flash Point Oils?

Redline's is 480, haven't seen anything higher than that.
What SAE grade are you looking for? Higher grades tend to have higher flash point and lower volatility (Noack).
Are you having a problem with oil temperature, or burnoff or high-temp deposits?
To answer your original question, ester-based oils tend to have good high-temp characteristics - look at Redline and RLI.

Redline's 10w60 is 495. 
I meant to say 10w30...so I'm curious what cheaper oils have high flash points also? hehe so along with the givens like the expensive oils, what are some budget players with a high flash point?
Are all the common brands sold at walmart group 3?
Trying to find a good bang for your buck for turbo application, but if I have to go redline I will

10w30...Because it's turbo is why I want to find out the high flash temp oils. Just fixed an oil burning problem, I am running M1 10w40 high mileage synth. And topping off with whatever 10w40 I buy at the time. I can totally notice the slower performance with 10w40 compared to 10w30. Since I fixed the oil burning I'm ready to settle into a 10w30 now. I may start out with a cheap ST dino to rinse the carbon and [censored] from burning oil, run that for 2-3K, and then go to my Synth.
I'm looking at a 6 mth OCI at that point.
It's a 2.0 turbo DD, AWD, 3/4 highway, 1/4 city.
Preventing oil from coking in the turbo, is a reason for wanting high flash point oil.

Redline 5w30 is 252C.
Valvoline NSL 5w30 is 238C.
AMSOIL European Formula 5w30 is 238C.
RLI 5w30 is 235C.
Mobil 1 HM 5w30 is 231C.
If you're looking to lower oil consumption, Flash Point is not the best indicator. NOACK is better for that. Red Line still wins, but AMSOIL looks pretty good.

Here's some info I got from: http://mcgeerf.tripod.com/americansyntheticoil/id17.html , not sure how current it is.
I think I'll just make a list of the higher flash points like those that are 440-450 and higher, and buy whichever looks the best deal at walmart. Then start out with 3 month OCI and UOA, extending from there if I can. Or if the oil can't handle the turbo, I can upgrade to Redline. Hopefully doing a 6 mth OSI if I'm running Redline!
Is VI important? Is higher or lower better? Royal Purple only has a 400 FP, not so impressive at that price point.

Ah, that makes sense. NOACK would be evaporation near a boiling point, but flash point is a much higher temp.

M1 10-30HM is 450F. If you are wanting a 30Wt. oil just go with M1 5-30 which as already mentioned has the Honda turbo rating.
That'll work, too. I was in the mode of answering the specific question of 5 highest flash points. M1 5w30's all seem to have FP's of 230C. HM was 1 better at 231C. I think any Mobil 1 oil is good for turbocharged engines. I ran M1 5 or 10w30 in a Pontiac Sunbird Turbo for 12 years, and got great results. When I traded in the car at 166k miles, it would not consume any oil over a 6k mile OCI.

Yes lots of 5w30 choice without having to go with the obsolete 10W-30 grade.

I'm not sure that flash point is necessarily a good or at least the only thing you should be looking at. An oil can (and will) coke long before it reaches its flash temp if it is not being circulated.
Low NOACK volatility and fairly high HT/HS viscosity should also be considered, I think.

A HTHSV of 3.0cP is fine for a turbo assuming bulk oil temp's are not excessive.

Exactly right. Flash point measures a combination of volatility and flammability, and the test method has a wide reproducibility of +- 15F, which means that an oil with a flash point of 450F can test between 435F and 465F at different labs. Marketers sometimes take advantage of this wide reproducibility range in reporting the flash point on their data sheets.
Noack measures just the volatility of the lighter ends of the oil, and correlates better with oil consumption.
