Keep the Mobil 1...I'm running Royal Purple 5W40.

Yes, this is a controversial topic, but I've read Charles Navarro and Jake Raby's comments and that's good enough for me.

Where are you getting Royal Purple 5W40? at a FLAPS?
what price you paying?

thanks

Does Royal Purple make a 0W40 and why did you go up to the 5W40? The 5W is for winter protection, right? Does 5W and 0W make a difference?

Jmatta,
Where in chicago-land did you pick up Royal Purple and how much per quart?

I usually get it from my Porsche tuner shop, but you can also get it through AutoZone (usually special order) or even Amazon these days. It will run you $9 to $10 or so a quart, but worth it (I change my oil once a year, less than 3000 miles).

I'd check with some of the high end european indy shops in your area; many of the indy's are RP dealers.

The recommended european formula is 5W40...I can't believe there's much difference between 0 and 5; I don't run it in winter anyway.

Check the online stores; lots of them carry it.

To my knowlege, Red Line is the only Group V full syn you can buy today. That is why I use it.

I use AMSOIL in my bike...got a bunch of Mobil 1 in the garage though so that will go first. Regardless, I cannot see why Mobil 1 cannot be used.

Wow. Had no idea I would stir up all the discussion with a simple rebate link!

Anyway, I enjoyed the opinions expressed. Jmatta mentioned Charles Navarro and I just happened to be reading his oil treatise.

I was reading the FAQs under "What viscosity should I use in my Porsche?" My brain is tired.

I'm now using the Royal Purple 5w-40 as well. I was able to order a case through my local NAPA. It's pretty spendy, but I think worth it. Before I switched, I placed a call to their tech support, and they were very helpful, and answered all my questions.

Because the 5w-40 is ACEA A3\B3 rated, I guess the additive package had to come from Europe.

my local autozone has Castrol syntec $25 for a case of 5, $7 each for M1 and $9 for RP.
hmmm....I'm tempted to go with the Castrol and change it a little more frequently than the RP.
How long is the shelf life for motor oil? I see oil prices moving higher and sooner than most folks expect. My local pump just jumped 7% in a week for high test.
Wonder if stocking up is smart.

I guess I will use the Valvoline in my wife's car...

Why, I wondered, have so few people commented about this test result? Do people not put much stock in the testing protocol and, hence, the results. Those results would seem to indicate we shouldn't be using oils such as Red Line, Elf, Mobil 1, and Castrol, oils that are often popular with folks on this forum.

Just playing devil's advocate here...I don't profess to know a ton about the subject, though I have been reading a fair amount online (to the point where my head's swimming and I think I've gone slightly cross-eyed!)
