Yes. Otherwise, Porsche would have approved it..their 5w-40 is approved....

Do I have hard data beyond that, nope. The oil arguments go round and round...

Where do u guys find M1 5W50 these days?

Also, is it still the better option (vs. 0W-40) for summer times, for cars that see the track?

Thnx

No HTwo O

Call Petroliance for an order or they may direct you to their web site- 800-628-7231.

IMO, it is a better option than 5W40 and 0W40. My UOA's are excellent.

Here's the web-site:

Do you have a Mobil oil distributor around you? Most major metro areas have them.

I just bought 4 cases (24 quarts) from a nearby Mobil oil distributor here in Hayward, CA.

I asked and they do not ship, they are *NOT* set up to ship oil.

What I do is drop by and buy the oil over the counter. In fact this time I had to walk a hand truck from the main office across the lot to a warehouse building where the handtruck was loaded with 4 cases of oil then walk it back and load the oil in my car.

I don't mind. In fact, I was offered a warehouse job. Nice to know if my software engineering skills fall away I can still make a living pushing a handtruck. (Maybe I need to think about renewing my forklift and overhead bridge crane operator licenses?...)

Anyhow with taxes/other fees/charges the oil came to just under $195 or about $8.09/quart.

Sincerely,

Macster.

AV Lubricants - its about $48 shipped for a case.

The car I purchased was using Motul 300v "Le Mans" 20w60
After looking into the oil choices, I will continue with that formula.
This oil is incredibly slippery.
No pressure lag on startup.
IMS noise silent until warmup.
In spite of expert opinion, I am a believer in hi viscosity lubricants in these engines.
In closed engines, heavy oil clings far longer to bearing surfaces than lightweight.
At high engine temperatures, light oil will "flash evaporate" more quickly; especially after shutoff.

To be continued..

Many experts here will tell you that viscosity is too thick for your Variocam system...

Kevin

Daytonaman, can you look in your owners manual and read what the required viscosity are for this engine. Like Paul mentioned, 20W is way to heavy for the vario cam hardware. I can see someone wanting to use 10W in a desert climate where the temps never dip below 90F.

No HTwo O

I've never met one that wasn't.

I personally don't care what Daytonaman uses in his car...what he shouldn't do is recommend that type of oil to others. The "positive" attributes he lists are qualitative and have no data to support any potential effect on engine wear or cooling performance of the oil (which is what the oil is intended to do).

Daytonaman

These are my own personal findings with the car I purchased. Not recommending anything.

You kind of did, but that's OK.

People fail to understand that oil viscosity is NOT like the display in the autoparts store where you turn the crank and see the oil sticking to the gears... Oil is used as a hydraulic medium, not just a lubricant. You cannot just increase viscosity and not risk unintended harms.

There are few people who know enough about these motors to make recommendations. "Kevin" above is one. Nuff said.

Your observation that high viscosity oil makes your motor quieter is misguided: so will 90 weight gear oil. Heck, I'll bet the pressure gauge shoots right up to the top- meanwhile the very high viscosity COULD be starving the bearing surfaces themselves.

You seem to have some strange "beliefs" about oil, like how light oils 'flash evaporate"....

Topic has been beat TO DEATH. No beliefs are needed, all this is known- and knowable.

Thanks Adam; Kevin has used Motul in the past although not 20w60. The oil debate for me has been whether or not to switch the car to a different product. The 300v has been used for the past 10,000 mi with good results; I cut the filter and there is no metal. I believe Motul is an imported Shell Oil product that claims 15,000 rpm formula 1 performance. I am not sure I am ready to just put "oil" into it..

Kevin

Yes, I have mentioned that Motul 300V is a great oil. However, you must run the lower viscosity. 20W60 is way to high for this engine.

While we are on this GREAT debate, I had a customer send me a link to Joe Gibbs racing oil. I am actually testing it right now. From my very brief exposure.. less than 2000 miles, it does look pretty good. I say this with caution. My visual cue and listening cues are giving me some hope.. My disclaimer is> the decision has not been made... Guys please hold off until I get a few oil samples and tested.
