Which Oil for tracking?

[Slideways]

Looks like a great product for older flat-tappet engines, or maybe certain race cars. I would not consider this a substitute for BMW 10W-60 or the other known-quantity engine oils for these cars for street use.

They list BMW LL-98 as a "performance level," not an approval. IOW, they think it performs at that level, but it hasn't been approved. Very common for aftermarket engine oils.

One thing I've noticed about high-ester oils: They also tend to have monstrous ZDDP levels. Not a surprise IMO given that ester competes with ZDDP at the surface of the metal. IOW, I'm sure that 1800+ ppm of ZDDP is doing good work, but it probably isn't doing what it seems like it should. And you'll still get the downsides of massive ZDDP levels, like ash.

100% PAO/ester with a ton of ZDDP looks great because none of the major OE-affiliated brands do it this way. But when none of the major players in a field do something, you can bet there's a reason.

To me, this looks like a band-aid product for when you need anti-wear at all cost. In a street-driven or even mixed-use M engine, I would expect the anti-wear benefit to be minimal-to-none and not worth the downsides.

What!? You're telling me you are not running you're S65 on 110 octane race fuel 24/7?

Good Catch there, I totally misread that, Trick Marketing !

Looks like Castrol 10w60 is no longer listed under the edge range on the Castrol Australia website
Label change too

Interesting.

Maybe they're in the process of updating the site and broke something? I just clicked around; it looks like they still have a page for 10W-60 oils, and Edge Supercar shows up on it – but the link 404s, as do all the links from the viscosity grade pages AFAICT.

I haven't, but

1. If I had to pick an oil other than OE, this would be high on my list
2. I ran Motul 300V for a bit in my old E36 M3, and I miss those sexy metal cans
