that's suppose to be available in the Spring of 2009?
Much more anti wear additives than standard oil and much lower viscosities ...

Cool that they are selling this online. Mmm, ordering 50 gallon drum online... That said, 0W-20/30?

From the site -

"I've been using Mobil 1 15W-50 in my race car. How are these new oils better/different?
Mobil 1 15W-50 is a higher viscosity oil that delivers a thick oil film for protection of high performance engines. While Mobil 1 15W-50 can be used and is recommended for both street and track use, the new Mobil 1 Racing oils are only recommended for use in race engines at the track. Mobil 1 Racing 0W-30 and 0W-20 are lower viscosity oils designed to increase power output versus higher viscosity oils. Most importantly, Mobil 1 Racing oils are formulated with anti-wear (Zinc/Phosphorus) chemistries at twice the level of automotive street oils to protect race engines including high loaded flat tappet designs used in the NASCAR series."

As much as I try and avoid all threads pertaining to oil viscosity (to put it another way...I'd much rather go in for a root canal, without novacaine, performed by an epileptic dentist who just discovered I have been sleeping with his wife and daughter)...... but why do I want 0W in a race car?

it is only a 0 weight at startup, 30 wt. at operating temp. This may be a good oil to mix in with other M1 offerings to beef up the additive package. 911 engines need a higher HTHS...It needs to be at least 3.4. I wonder what this new oil has.

or just run Redline Racing or Brad Penn racing's 20w/50..

911S3.6

...or Motul 300V, 20W-50, pure synthetic.

If you are thinking about running in a street car with Cat's it may damage them see below from the link above
Automotive street use oils that meet the latest industry standards are required to have a lower level of Zinc and Phosphorus anti-wear chemistries than oils formulated years ago. The latest automotive street use engine oils are designed to be compatible with emission control equipment. Mobil 1 Racing oils are formulated with anti-wear (Zinc/Phosphorus) chemistries at twice the level of automotive street oils to provide enhanced protection of highly loaded valve train systems found in some race engines. Based on the high level of anti-wear chemistries, Mobil 1 Racing oils are not recommended for street use.

Dont do it! (at least not if you are doing any track use) Amsoil racing oil is probably the best stuff out there (along with redline). amsoil now has added zinc in their racing oil.

it is easier to talk about religion or politics than oil. Must say I am not going to be rushing out to put the 0 in my 944. Now if I had an RS spider it may be of use!

Larry Herman

If is purely a racing oil, why bother with a multi-weight? I don't see the point, especially if the operating viscosity is down around 20 or 30 weight. I'll stick to my Amsoil, thank you very much.

I'm certainly not an expert but my understanding is that most pro teams in various series from NASCAR to F1 run a very low viscosity weight oil...They probably know more than we do...

The big complaint as far as I understand it is the lower additives package that has been formulated to maximize mileage and minimize emissions. This seems to address that.

Larry Herman

When it comes to minutia, certainly, but when it comes to general concepts probably not. Lower viscosity = less friction = more HP. Neither Nascar nor F1 has any long term longevity concerns, just as long as it lasts 5 or 6 hours.

For our usage, longevity is paramount and so once again, we cannot look at what the top pros do and conclude that we should be doing like-wise.

The issue I see is running a thin oil is great for power. Thinner the oil the less pumping losses. So maybe 1-2 more hp. However for us club guys (especially 944) that could mean extra wear during hot high load running. Fine if you rebuilt every 4-5 races. Not so good it you want to rebuild every 4-5 years.

EDIT... Dang Larry beat me too it.
