Re: What Race Oil do you trust?
 

Has anyone tried the new "Maxima Race Oil " ?

We use a lot of Shaefer Racing oil and we build round track engines and have had excellent results with it. We use Spectro break in oil and we build lots of flat tappet,high spring pressure engines.

We use Schaeffer Oils in our engines (we are using 5-50 Supreme Synthetic in the 632" (right now). I used their 5-30 in my Stocker with no ill effects and it was faster than 20 Redline. (at least in my engine).

I have used Blackstone Labs to do my Used Oil Analysis. If you haven't done that I highly recommend them. You can find out EXACTLY what is going on in your engine after each oil change and monitor the change or spot early problems.

I tried the Comp Cams 15-50 Break-In oil on the dyno and when we sent it in Blackstone's rep wrote a nice email that stated it has the highest zinc, phosphorus and Calcium package they had seen in a while. He recommended I stay with it vs the Schaeffers I had been sending in, I have 10 1-gallon jugs of Schaeffers so I will use that up and go back to the Comp Cams Break-in. It is a litttle heavy for stock but with that much Zinc it might be worth running and change oil for a heads up and save the oil to use again.

I think oil filters are as important as the oil. I keep thinking K&N should be the best but my engine guy is stuck on WIX racing filtes, what are your opinions (don't want to steal the thread, sorry, I may ask that on a different thread.

We used to sell Schaeffer Oil and it is a good product, its right there with the high end
race oils as far as performance at a substantially better price but like all passenger
car oils the zddp package is reduced because of emissions so add a little zinc approx
2500 ppm and you have a very good race oil. As far as WIX filters go i would stay with
them as they are a very well built filter with the correct media for a race engine, a little
higher micron rating for high flow and less pumping restriction.

I use NAPA filters, which are made by Wix. Cut one apart along with a Fram. I have not seen inside a K&N.

Really interesting reading here.

Re: What Race Oil do you trust?
 

Please don't let me steal the thread, but has anyone tried the Mobil 1 dedicated Racing Oil----not the off the shelf....they have a dedicated oil product, check the Mobil 1 racing website if you haven't already.

Looking into Penrite Oil, looks very interesting....

Reviving this thread to ask if anyone has given thought to Viscosity Index? As I understand it, the higher the VI number, the less the oil changes with temperature. In trying to be as consistent as possible in our classes- cold morning runs vs a hot laps, would it make the most sense to run oil with a high VI? I've noticed Royal Purple, Eneos, and Driven have high VI numbers.

I would also extend this question to ATF and Differential as well.

Re: What Race Oil do you trust?
 

I run strickly run MPT oil out of New Jersey in my engines. 20wt with zinc already added. Plus he makes me whatever viscosity I want for heads up runs.
