Mobil-1 Racing oil?

[terry lee]

Has anyone purchased any Mobil-1 synthetic Racing oil?
I can not find a retailer in my area (South Fla.), and half the retail idiots I spoke to don't know the difference between the racing oil and Mobil-1 for the street. I spoke to all the distributors in my area; and the Mobil Corp. office to no avail. They only refer me back to the distributors, and they didn't know the difference either. Am I on some other planet? I don't get it! The web site has all kind of info, but not where to purchase.
This is driving me crazy!
Ready to change over to synthetic, but can not buy
Can ANYBODY shed some light on this?

...there is no difference.
15 W 50 is considered the race oil unless something has changed

[Clois Harlan]

I concur with Steve. I am running Royal Purple synthetic racing oil and I believe it is 15 W 50. Labeled as Racing 21.

Just a word of warning from a couple of the engine builders around here:

Do not use the 0 W 15 weights if you are doing any track time. The racers that run these lower weight oils can afford to rebuild their engines a lot more often than most of us. Plus the horse power gains are minimal. I have no personal opinion, just what I have been told by several racers and machinists.

Steve,
0-W-30 is the weight of the racing oil, and they are different forumlas as per the website. The racing formula can withstand higher temp's and has more additives.

Just read it on the site. I am confused. I would have never thought that they would use something that light. It contradicts all other theories. As you know , I have a Winston Cup car. The motor was built by Mark Smith at Tristar who build for lots of Cup and Busch. I was told Unocal 20W50 or the equivalent in Pennzoil. If you are using an old tech solid lifter cam, the thin oil might be a problem. Also, the tolerances your motor was built with should dictate the grade. I know drag racers have been using thin oil for years and if Nascar can get more HP with thinner oil, it might win a race. But they rebuild after every race and use fresh motors. I saw about the HP street car application but I am puzzled. I will talk to my engine builder and get back to you.

Just a thought -

Be careful running heavy oils (20W-50) with high volume and/or pressure oil pumps and oil coolers. The higher viscosity oil will put more stress on the gears running the pump. Run the lowest viscosity possible that produces the pressure you desire. Flow rate should count as well as pressure.

Also, it could be that much of the oil pumped just exits via the pressure relief valve rather than flowing through lengths of hose, an oil cooler and a filter.

More additives makes for poorer lubricity. That is why 10W-30 is preferred over 10W-40. To get the 40 to perform at a pour rate of 10 takes more additives, which means less oil for lubrication.

I concur with Bob on the weight issue, too.

blykins: I use Valvoline in my FE. It was recommended to me by my engine builder (who advertises here). He recommends VR1 20w50 Racing, or the straight 50 weight VR1 during the summer (when temps are going to stay 70+). I just had the oil changed from the 20-50 to the 50 a couple weeks ago, and the mechanic that did the change said that he probably would have stayed with the 20w50 year round, and that the 50 was too heavy (in his oppinion). The guy that did the change isn't my normal mechanic (he's on vacation), but he has a good reputation for being a top notch engine builder. ........Then again, so does the company that built my engine, and HE recommended the change to 50. He also told me to stay AWAY from the synthetics (???), which I thought was strange. He said it was too thin for the side oiler FE (which are prone to leak). When I heard "known for leaks" out of the guy that built my engine, I thought perhaps he should have spent a little more time on the build!
What do you guys think???

Hey Guys...I work for Valvoline at an engine lab....
The racing oil does have a different formulation. We have different batches here....15W50 and 20W50.

The formulations for the Valvoline MaxLife are also different...and they do work. We've done numerous dyno tests on older cars.

Blykins,
I just called the store where I have purchased Valvoline straight racing formula oil in the past, and inquired about the MaxLife product. I was told it is for older engines. They didn't carry any synthetic racing oils.
What is the product name for Valvoline synthetic racing oil? Is it available thru retail outlets.?

Still no answer on WHERE TO PURCHASE Mobil-1 Racing formula!
Thanks for all the other info though.

Yes, the MaxLife products are for engines with 75000 miles and over...I should have made that clearer up above. I was just generally rambling...hehehe

The Valvoline synthetic racing oil is called (here's the clencher) Valvoline Synthetic Racing Oil.....hehehe....it's in a dark charcoal gray bottle....and says for racing purposes only on the bottle.

I've seen the stuff at retail outlets....AutoZone, Advance Auto, Pep Boys, etc. You should be able to get the Mobil 1 stuff there too....don't know why you can't find it....that's weird.

[CSX 4027]

Have you done tests with the Pennzoil Racing 25 W 50?

FYI; from Mobil website:

"Fully Synthetic Motor Oil Used by Professional Racing Teams Now Available to Car Enthusiasts

FAIRFAX, Virginia (November 4, 2003) - High-performance automotive enthusiasts will soon be able to get the same boost and protection that professional race car drivers get thanks to the introduction by ExxonMobil of its new proprietary racing oil -- Mobil 1® Racing 0W-30. The new formulation will be available to the public in early Spring 2004.

Previously available only to professional racing teams, the Mobil 1 Racing formula combines the best of Mobil 1's patented SuperSyn™ technology with boosted levels of anti-wear additives, giving maximum protection and minimizing internal friction for exceptional power output. The specially designed high-performance motor oil is recommended for professional and amateur horsepower enthusiasts because it provides the performance drivers want from their high-powered engines every time they get behind the wheel.

"We developed Mobil 1 Racing for people who live to drive high-performance cars," said Tom Olszewski, technical services advisor at ExxonMobil Lubricants & Specialties. "Whether they put Mobil 1 Racing in their Honda Civic or Grand Prix GTP supercharged engine, drivers are going to notice a difference in how long their engine lasts and how well it performs under extreme driving conditions."

I also found out that this formula is really for one race events, when you tear the engine down after the event - no additives for down time between events - Regular Mobil-1 is probably better suited for my use as per RDI (my engine builder)

Just thought I would pass this along.

What I've been told repeatedly is that FE's tend to leak somewhere, or at some point in their lives, no matter what you do. Thus, I'm told, the only downside to a synthetic in an FE is that it'll find a place to leak quicker.

[blykins]

Terry, our website says that our synthetic racing oil is available at NAPA....you might wanna check there.

[auto10x]

Beware of specially formulated racing oils. They do not have the additives to deal with the conditions we encounter during normal day to day driving (engine idle, cold startups, urban driving, etc.). If you are only talking about constant high speed and high temperatures it may work well.

I use 15w-50, mobil 1. I get it for free, so I'm kind of sold on that brand.

Pressure runs between 40 pounds at idle to 75 to 80 on a rev. Whent the oil gets good and hot, the idle pressure drops to 30 to 35 PSI and the high drops to 65 to 75.

I pump 8 quarts from a 5 baffle pan with SS "bypass" plumbing and .125 restrictors. Tried .040, 060 and .1, but the "feeling" wasn't right at the crank after a run.

10.5 to 1, punched .030 with 63CC heads.

My oil is Mobil 1 synth, 15w - 50.

Just my $0.02
