Been reading a lot about RLI, want to try them out. This would be oil for my two Mercedes. They're both using Castrol Edge 0w40 and 5w40 right now. These engines are both start/stop engines and direct injection.

Would the 5w30 be a good place to start? Actually located in San Diego and the cars will never see snow. Plan is to run them for about 5k miles and then run a Dyson analysis.

I think the OP was referring to Renewable Lubricants Incorporated.

I do not see any advantages in using the RLI engine oil.

What is the motivation behind this choice? Sounds like the Vegan version of snake oil

Hmm think it's more like vegetable oil!

Renewable Lube Inc uses bio based oils rather than petroleum. If you're ecologically inclined they're a good choice.


OP I agree with a sample at 5k; you may be able to leave it in but RLI is not known for extended drains.

Does either car have a problem that you think RLI oils might solve?

This^^^
 
Until we see a UOA in his application we can not make that call IMO.

Every formulation from every manufacturer operates differently in various engines under various conditions.

What might work well in one may not in another.

Nope, both run perfectly. Just looking for the best quality oil I can get for the dollar that offers maximum protection.

Well, there's refined crude which is turned into mineral oils, then there's crude which is reacted into synthetics'.

And then there are bio-derived oils.

RLI uses a combination of the above.

How is a UOA going to prove it?

RLI is a Group IV/V oil. No Group III in it.

RLI is known for reducing engine wear on VW/Audi direct injection engines when compared to 502.00 certified oils. There is a big thread on this in the European/Import oil forum.

You answered the question before i asked. I was wondering if this oil is predominantly Group V.

Thanks.

It will show him how it's performing in his application and then he can compare it to the cost he is paying and determine if an off the shelf synthetic better suits his needs.
 
I doubt the boutique oil is needed to bring your vehicles beyond your ownership of them. RLI seems to keep the parts separated. There are some posted UOAs of RLI.

the Group IV is the carrier of the additive package.

If you only do a UOA, don't be surprised when you see a lot of copper in the report. Copper is part of the additive package.

As soon as my warranty expires, I'll be going back to RLI. Right now I use 502.00 oils with Liqui Moly MOS2. I plan to start stocking up on RLI Biosyn SHP Low-SAPS 5w40 (or maybe try 5w30 to milk out a little extra fuel economy).
