Which Oil for tracking?

Anyone tried this?

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

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.

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.

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

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

I know. I suck. 😕

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.

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.

Just throwing some jet fuel on this thread

In Australia we have this oil, currently not mentioned

It's a BMW approved LL-98 oil

Used the Castrol 10w-60 supercar for like 10k track/race miles. Just switched to Redline 10w-60. I am going to assume it will all be fine. I change every race weekend.

By OE do you mean the original TWS oil or do you mean the current "Twin Turbo" oil from the dealer?

both

[samthejam]

Agreed. I've seen too many S54s run a long time on OE oil. Its a known quantity. Although I think I could lower peak temps with another oil, I still run the OE10w-60.

Unless I'm missing something on Castrol's website, it looks like Edge Supercar / Edge Euro Car 10W-60 is the only 10W-60 available from them now. That tells me any Castrol-branded 10W-60 with a different name will be an older product, so almost guaranteed to be a different formula. Formulas change all the time for various reasons, even when the branding/label doesn't change.

Private label stuff (e.g. BMW TwinPower Turbo 10W-60) might be a straight-up rebadge, or it might be a tweaked formulation. As Slideways said, can't tell without an oil analysis (and might not be able to tell even with one).

I have used nothing but Castrol 10W-60 since I purchased the car about seven years ago. First TWS, and then Edge Supercar once TWS disappeared. Do we have any reliable information as to whether the Edge Supercar is the same formulation as TWS?

You'd have to send in a sample of both for oil analysis to confirm, but I would guess they are the same. I don't think Castrol would want the added cost of making two different 10w60s.

Same as current or old TWS?
