What oil?

Liqui moly!

We're talking about Ravenol RSS 10W-60, right? (they have another 10W-60 that's for high mileage engines)

Ravenol does claim "very good detergent and dispersant characteristics", so it's probably fine for short-to-moderate oil change intervals (if not longer).

Two things to keep in mind about detergents/dispersants:

1. They compete with anti-wear and anti-friction additives, and
2. They tend to be "ashy", i.e. they leave (certain kinds of) deposits when burned.

So, if you have less detergent/dispersant, you might want to run a shorter OCI, but you could also end up with better performance in other respects. And given that anyone considering Ravenol probably won't be running long OCIs in the first place, there probably wouldn't be a loss in that respect anyway. FWIW.

I'm not saying anyone should necessarily run this oil over any other, but there's zero need to worry that it might be less street-worthy than other options. Worst-case scenario, you can use oil analysis to determine a reasonable OCI (one of the few things oil analysis is actually good for in a real-world car engine).

Yes I am talking about the Ravenol RSS 10W-60. I don’t drive my car more than 5k in a season so this might be a good choice for me.

I can’t find the documentation to confirm (probably lost on the old forum) but it seems like this could be the closest of what is available to the original blend of Castrol TWS. I remember that also had a pout point in a class of its own.

This thread made me do some research - I haven’t looked at oil options in years. The Ravenol is interesting - I just don’t know if it has the detergents needed for street use, they advertise it for racing.

I know many brands are moving their USA versions to group 3. I decided to email Liqui Moly to check if they have done the same.

I will continue with liqui moly + ceratec

I know on your german website you advertise Synthoil Race Tech GT1 10W-60
as vollsynthetisch - meaning it is made of only group 4 and group 5 oils
due to the regulations in Germany.

Is this the same oil that is sold in the USA? Or is the USA version based
on group 3 oils ?

It’s the same Gr. 4 based oil.

Please let me know if you have any questions

Those of you who use the BMW stuff via FCPEuro - what is the most cost effective way to do the return shipping? Does it fit in any of the USPS flat rate boxes?

I keep all the packing from FCP, repack the old oil and filter, and ship Fedex....around $15.00. For me, the ease of using the FCP packing and Fedex is not worth trying to save another $5 or so for other methods....I'm old and lazy.

I use FedEx ground as they do not ask that question about "anything liquid".

I keep a few boxes in the right kind of size around. If all else fails, I just use the boxes they send me stuff in. I have a FedEx business account so I just use that to ship. It's insanely easy to sign up and you get slight discounts. Still slightly more expensive than USPS but more reliable IME.

Called the parts dept to see what they could tell me. All he knew, they were no longer stocking the Castrol brand and only the Audi brand. He wasn’t told who manufactured either ( I don’t think he cared lol). He said the only car they use it on is the R8. I should have stopped at the Lambo dealer next door to see what they are using. My guess its the same...

[lunardds]

Vw dealer told me that they switched to mobil one as their oil supplier instead of castrol. At least for the TDI oil I buy.

[oceansize]

I remember a while back Audi was stocking Castrol brand 10w60. Is this still Castrol or did they switch manufacturers?

My 2019 VW Tiguan takes 0w-20 and the first two oil changes the Castrol Professional LL IV FE was available but this last round I received VW labeled bottles and the Castrol was no where to be found. Seems like the Castrol has reappeared in a few places now but I also couldn't determine for sure who produces the VW oil. Most seem to agree it is re-labeled Castrol but I didn't see anything concrete.

I just picked it up yesterday. It came in a sealed box so I didn’t think about it until I got home. I got the surprise when I opened it. If its repacked Castrol I’m good with it. I’m surprised internet searches aren’t pulling up anything.

When did you buy that? I went to an Audi dealer a couple months ago and they sold me Castrol bottles. I really hope they're not switching to that.

[IamFODI]

I'd be shocked if TWS went away. It's almost an institution unto itself.

What might happen when a manufacturer drops it is that Castrol might stop caring about optimizing it for that app. Which, incidentally, is already a possibility for M cars.
