What oil?

[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.

[8000RPM]

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...

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 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.

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

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.

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

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.

How original are we talking? TWS's provenance goes back decades at this point. :]

TWS is a great lubricant with a great history. AFAIK it has historically gotten Castrol's best tech. It's also a great example of how stellar performance requires not heavy additization, but the right additization. It didn't have the kind of everything-but-the-kitchen-sink additive package that other "boutique" oils had, and yet it -- not they -- found its way into serious race cars and OEM applications.

These days, there are several options like that. I know some people don't want to hear this, but BMW TwinPower Turbo 10W-60 seems to be in that class. Shell Helix Ultra, Liqui Moly, Ravenol... It's not hard to find a good lubricant in this class. Nothing has the heritage of TWS, but there are plenty of potent competitors.

Get a good name brand oil in correct viscosity range and you’re good to go. These days people are over thinking it for what are essentially street engines

As others have stated, I just hang onto all the original shipping materials that come from FCP, and pack the old oil and filter for return shipping. It’s usually $15-17 to send it all back and when asked, I just say “car parts”.

I’ve gotten the most hassle from the post office, less so from UPS or Fedex. If I’m using some third party generic shipping store, or the shipping counter at Staples, they don’t seem to care at all.

[sc_tr0jan_m3]

after looking through some more reviews, i may switch back to the OEM oil via FCP. LM doesn't appear to perform as well.
