Royal Purple 5/30 and 10/30

[FTD]

thanks for your research.

5W30 and 10W30 are for Japanese motors. Could do with 0W50 or 5W40 I guess depending on the climate of the state you live in.

Until Royal Purple (any weight) has ACEA A3, B3, B4; I wouldn't touch it............

IMO if it's not on Porsche's list of approved oils don't use it.

Why do you suppose it is that some of the most highly touted motor oils (Royal Purple, Red Line, etc.) don't seem to make the list? (I'm guessin' somehow it's money-related, but I don't really know.)

Paul, what do you use? What do you think of the Castrol synthetic?

Rather than “speculate on the monetary veracity” of the Porsche list, why not do some research on what specifications (e.g.: ACEA ratings) the oils that they do “approve” have or don’t have? Could just be eye opening as well as informative………..

I have researched oil for the last year on this forum, in other forums, in discussions with autoXers, generic internet search, etc. I never came across ACEA commentary however. Hmmmm. I'm an expert on many things, but not all things, which is why I appreciate forums like this so that I can find others who are.

Thought I would share this below because I think its funny. Access to web sites are blocked from my work computer.

ACEA (European Automobile Manufacturers Association) Ratings aren't really any different or more stringent than those from API (Am. Petroleum Institute) or SAE (Soc. of Automotive Engineers), it's just those crazy Euros coming up with their own system to prove that they - the United States of Europe, aka the EU, are just as good as we are.

And, don't confuse a ratings claim as a certification. NO oil is ACEA approved - the ACEA does not approve motor oil. The Mfgrs. are just claiming to be in compliance with ACEA testing standards. Oil mfgrs. are responsible for their own testing and conformance to ACEA specs is voluntary. Just because a manufacturer doesn't claim ACEA compliance for their product, doesn't mean it isn't, especially if they are already complying with API or SAE specs.

I think we're seeing waaay too much Oil paranoia here lately. People obsess about which oil to use and then add a K&N or Gauze filter which introduce far more contaminates than oem, or go 15k mi. between service intervals. That's kinda like smoking in the doctor's waiting room.

Choose a name brand synthetic of your choice, swap between 7500 or annually (unless your conditions dictate otherwise), and you'll be fine. Using MB1 under these circumstances will not increase the odds that you'll grenade your engine anymore than if you choose Pirelli or Continental shoes for the car. Remember, EVERY Boxster leaving Stuttgart or Uusikaupunki, for better or for worse, has a belly full of Mobil 1.

If your engine does implode, it's much more likely that the poorly engineered IMS bearing or RMS are to blame.

My 2001 came new with 0W-40 Mobil 1,why change?

It uses no oil between annual oil changes (75,000 miles on it so far).

My advice after hearing these arguments for 40 years? Use an approved oil and change it annually.

IMO anything else is nothing more than a waste of your money.

Wow. Never fails to amaze me at how emphatic people get when talking about motor oils!

I will give some backing to the notion that the current Mobil 1 is not the same Mobil that we've all been buying for the last decade. I will also agree that Royal Purple is a bunch of marketing fluff.

As for what's going in my car: Lubro Moly. Has Porsche's blessing, and is made in Germany to boot! "C'mon, you know the Germans make good stuff."

In a final closing point, in my opinion, unless you're buying the cheapest Walmart branded stuff you can get your hands on, any of the modern oils are fine in your car provided that you change it more often than every 20k miles.
