Castrol Edge 0W30 is back with LL01.
Really? Awesome! is it still “high” PAO?
I’ve been using Euro Castrol for 40-45k miles (approx 9 OCI’s), “stretching” the OCI’s to 4500-5000miles (OM says 3750), which is about 12 months or so. car has 146k total. Still getting single-digit wear metals on the UOA’s; I’ve tested only 4 times. Ending KV100‘s mostly low 11’s, lowest was 10.8. TBN’s 3.2-3.5). Current fill is mix of the last of my 0w30, with 0w40 (About 50-50%). I’ve been thinking of what next, but if 0w30 Euro Castrol has returned, I’ll be looking for it…before Dec 2023 (LOL). Without any compelling evidence, I prefer it to the 0w40. It used to lose a little oil, but replacing the O-ring on the oil filter/cooler sleeve appears to have rectified that. hoping it will last a bit longer, given the crazy prices for cars recently.
To the OP, I don’t know how tough your climate or driving style is, or how much more your engine is tuned compared to my bone stock ~250hp 2007 turbo, but the Euro Castrol has done well for me. It’s possible any Euro 0w30, 5w30, 0w40 oil would do as well. I do like this Castrol better than “normal” USA SN Mobil 1 5w30 (which I used while under extended warranty), which in turn, I liked better than Pennzoil Platinum 5w30 I tried once… Which might have been SM, maybe SN...whatever we had 10-11 years ago.
people might think I’m paranoid about oil…in my Ford EcoBoost, they’d be right. It isn’t the Subaru that causes me to lose sleep. The two shops that have seen my Subaru in the last 5 years both like Motul. I wonder what they charge their customers for Motul nowadays?
