All this talk of turbos not lasting very long and my son keeps plugging away in his 2002 WRX with its original turbo. It’s at 397,000 km right now! Original engine and transmission too. 

I bought this week a 2024 Ford Bronco Raptor...

...with the 418HP 3L V6 EcoBoost twin-turbo engine and that's still under Ford's three-year and five-year warranties... I live in Phoenix, where the official ambient high temps reach into the hundred-and-'teens routinely during our six-month summer and the actual airtemps above the roadways are about 10dF. higher than that.. I'm increasingly concerned about Ford's requirement of the use of 5W-30 engineoil, thinking that it's a little thin and that the next-thicker grades of 10W-40 or at least 5W-40 would do a better job in my application.. I'm also thinking that I can afford the very best engine oil I can find rather than the least-expensive 'full-synthetic' group-3+ oil that Costco sells.
Obviously the 'safest' thing to do is strictly follow Ford's requirements for warranty-compliance purposes, but I'd really like to use Red Line 5W-40 oil.
Have you any advice for me?
ford's recommendation on 5w30 will do.I bought this week a 2024 Ford Bronco Raptor...

Absolutely. Volvo Turbos were in a different world than, say, Mitsubishi Starions back then. Nobody should ever argue against good driving, cool down periods and the magic potion of frequent oil changes.I had an '86 Volvo 740 Turbo from new. Kept it for 18 1/2 years and 285,000 km. Still had the original turbo. Sold it to friends. They kept it for 5 more years. The turbo just kept on going.
That turbo wasn't water cooled either (it was in the next model year).
My secrets: Regular oil changes (every 3 months). Let the turbo cool down after a hard run before shutting the engine off. Let the engine warm up on really cold days before using any turbo boost.
RL 5w40 has a HT/HS of 4.4, so it's not shearing down. Not sure where you got that one from. It will only drop down a grade if there is fuel dilution. RL is still to this day one of the most shear stable oils I've ever seen.RL 5w-40 will shear down fast to a 30, no point doing that.
That's even better, oil choice doesn't matter if it won't be there for 100k. The wet belt is an oil submerged belt that drives the oil pump and these like the degrade although the newer ones don't degrade as fast as the earlier ones. Still if one wants to own these to or beyond 150k miles that becomes a concern.OK, what's 'that wet belt'? And I'll be long-ago dead and gone by the time that vehicle sees even 100Kmiles.
'That crummy font' is the world-famous and -admired Times New Roman.. In contrast to the sans-serif Arial type face that's default here and in almost-every website, TNR and other 'serif' typefaces have small horizontal stubs that allow one to see, for instance, the difference between the single characters 1, L, and I.. I find it much easier to read than this Arial.
I had no idea you could change fonts in the browser. I looked up font in chrome settings and it popped up, guess I'll be playing around with this for a while. I'll see if I can make it a little bit bigger as I think that should help with my low resolution.You can force your browser to use whatever fonts you want, this is mine in firefox:

I'd use any of the oils mentioned above so far. Can't go wrong with any of them. Lot of options.
I like Amsoil in a turbo.
Agreed....I'd probably run a Euro 5w30 like Mobil ESP, Pennzoil Euro or Castrol Euro if that were my Raptor but your suggestions are also dead on IMO.Lot of good oil under $30 per 5qt jug. M1 EP, Castrol EP, PUP, QSUP, to name a few. Any would work well.
Doubt it. It's one of the most shear stable oils you can buy. I think you're thinking of a 0w40.From my memory based on UOA's, it does shear down. Guys on the ramforum have tried this.
