Mobil 1, Amsoil or Royal Purple?

Amsoil

I know you guys say that Amsoil is a good product but expensive. Just so you know there is a way to get it a wholesale for cheap. I am a dealer and can help you get those deals. Let me know if you would be interested. Thanks

I prefer Mobil 1, but mainly because OEM's use it more. I don't think Royal Purple or Amsoil are worse, maybe slightly better but I don't think the cost is justified, IMHO.

Mobil 1

Does anyone know what Mercedes Service Dept uses for their synthetic oil?

For instance, I know Audi uses Castrol SynTech, but not the made-in-the-USA stuff. They use a Castrol version that is made in Germany.

My choice of synthetic motor oil: whatever is on-sale and/or w/ a rebate-promotion!

Which means: Mobil 1, Quaker State Ultimate Durability, Pennzoil Platinum, G-Oil, etc. I don't run extremely high HP applications, so a quality synthetic lube is a-ok for me provided it's changed regularly & paired w/ a premium oil-filter along w/ periodic air-filter servicing.

In Europe, the factory fill for the AMG & Brabus models was Aral! It was a surprise to me, but then I researched further to learn that it was an exceptional high-weight synthetic motor oil.

I've always used Mobile1. Porsche also recommends it for my C4S that's good enough for me.

Mobil 1. That's what we put in the E350, and what MB recommends. Who am I to argue otherwise.

Audi (and VW likely too) USDM offerings are VERY particular to the spec of motor oil, and the warranty (along w/ engine well being) are contingent on that Euro spec motor oil as you alluded to. There has been carbon/sludge issues on the DI engines, more common than acceptable (to many)...

Yea, I know what you mean. For my Audi, I won't buy the oil unless the back of the container says VW 502, 505 compliance. I'm looking at the back of Mobile 1 0w-40 right now, and it also lists MB-Approval 229.3 & 229.5. Is that the Mercedes oil standard?

I drive a 911. Came from the factory with Mobil 1. I stick with it.
