300.000km - oil: Castrol Edge 5W-30 and a new vortex breather - without oil consumption

315.000km - oil: fuchs titan 5W-30 and the old vortex breather - around 1L oil consumption

I’ve only used this Mobil1 oil for my 21 Camry SE. I do 5k intervals and it’s been great for the past 60K.

I run 0W-40 Mobil 1 European that meets the spec on the bottle. 10k changes since new.

I have been told the same by Blackstone on my cars, though I still do it once a year given the cost is <$75. However, I do follow their advice on intervals, after once being a 5,000 mile interval guy. On all three of our cars, using Castrol Edge 5W-20, I've repeatedly gotten analysis that tells me that, at 7,500-10,000 miles, the oil is still performing as intended.

Ive owned four 5.7s starting in 2005.

Changed all of them with 5w20 full synthetic, no real allegiance to a brand, but always a major brand (Mobil1, Valvoline, etc); typically 5k - 7k miles  between changes .

2005 had 250k , burned no oil, died when it hit a tree

2006 had 240k, would use 1/2 qt over 5k miles after about 225k.

2013, traded in with 225k, burned no oil.

None of these ever had a valve cover off.  I purchased the 06 and 13 new.  The 2005 I purchased with 100k on it.

The 4th is a 2021 with 35k on it. So far, so good.

I've been running 5w30 Mobil 1 full synthetic on my 03 hemi. 238k miles and still running perfect with no tick.

Mobil 1 ESP has specs very close to Subaru Japans own Pleiades oils. Its got loads of great certs, is widely available, well priced and highly regarded by loads of people.

I've had good luck with Castrol for several years in two WRXs.

It's a ok. Ran mobile one in my s50 sometimes rotella t6

my vw eats full synthetic castrol 5w40. thats what the dealership recommended to me.
