Engine oil Castrol or MOTUL

High mileage oils like Castrol edge have more detergents than other oils, not a marketing gimmick.

Change my e90 n52 every 15k, castrol titanium 10w-40. blackstone reports confirm the oil still meets spec with plenty of detergents left. Showing no signs of wear at 170k.

I used Motul 300v 15w50 for my track days at Circuit de Catalunya, Circuit de Calafat and Circuit de Castelloli because of the extreme heat.

Motul eco-lite 0w/20 bought on ebay in bulk is cheap and it’s a 100% synthetic oil (better than full synthetics). Just posted an oil analysis report from blackstone labs. It’s a very good oil.

I've been using motuls hybrid oil that's specifically for hybrid cars on my gen 3 prius. Gave me +2mpg onto of what I do and "nicer" ride

I just run castrol edge on mine. No issues.

Motul testing came back and it’s pretty impressive. Definitely gives Valvoline max life a run for its money.

I myself use Castrol Edge (in 0W20) for my GJ. But I add a bottle of Lubro Moly MoS2, for that added molybdenum (mimics OEM moly infused Mazda 0W20).

Been running Euro blend Castrol a few years and happy with it. Engine is getting close to 200k, modified, driven aggressively. I'm sticking with works for me.

Not certain what Castrol makes for a synthetic, but I know I experienced white foamy build up on my oil cap on a previous vehicle using Castrol. Switched oil and it stopped.
