Penn vs Valvoline test results..Ed Wright

[Stick Racing]

May I ask the part number of the Valvoline oil you refer to?
I have used the VV850 in the past but they no longer offer it.
I believe they changed the formulation.

Do you use an additive with the oil?

The oil I used is straight 30 racing oil. It used to be commonly called VV223 but the Valvoline part number is 822401. Scroll down a little to find Valvoline's conventional oil part numbers, https://www.valvoline.com/our-produc...vr1-racing-oil

I don't use any oil additives.

don't use either.

Been running Mobil 1 Synthetic 10w-30 in my race engines for nearly 3 decades.

This past season switched to Lucas Synthetic. Have a case of Maxima Synthetic that I will run this season.

Finished the 2018 season using Red Line 5-20 synthetic race oil. There was very, very little additive separation when I pulled the pan. What you see in a cold oil pan...full of cold oil...isn't an indicator of what's happening when the oil is hot and flowing.

The oil deal is a bigger issue for Stockers that have to use a flat tappet camshaft combined with high spring pressures and aggressive lobe profiles. For those not running under that set of rule constraints, there are dozens of oils that will work well.

Excessive additive precipitation is something to consider when choosing an oil filter. Those dots can be connected accordingly. -Al

The question that I can't seem to get a decent answer to is why so many racers use multi weight oil instead of straight weight.

It's my understanding that multi-viscosity oils get circulated faster on start-up when it's cold, which helps protect sooner and reduce wear. I also read some time ago that multi-viscosity oils make more HP, but I don't recall why. It might be that drag engine oil don't usually reach "normal" operating temperatures, if I understand viscosity numbers correctly. (i.e.: 10w-30 - 10w=cold, 30=hot.

Valvoline says that straight weight oils are usually recommended for smaller and older engines.

Specifically with respect to ring wear?

I had really good luck with the full synthetic Valvoline racing oil. Cant seem to find it anymore at the local parts stores.

I've been really happy with JR-1

You may want to look at Reher-Morrision tech tips on oil and filters, oit of 100 tips they are toward the end (95 & up as I recall) Filter tip very interesting

One thing they told me was to try Bad *** oil, I believe the originator of the early good Royal Purple.

FWIW

Thanks Ed!

There is a racing oil brand that has been recommended to me by Nick Ferri.
It's manufactured in the USA by HPL Superior Lubricants.
Nick shared with me that it is the oil he has been using for some time; it makes power and protects the engine. I believe Bo Butner is also using HPL Racing Oils too.

For a tough heads up, mine is just a few hundredths quicker on Royal Purple "race 9", which is, IIRC, zero-10wt? Pours like water.

A friend in the lab at the Sunoco refinery here locally tested some oils for myself & a couple of racer/friends. The highest load before gaulding the ball on the load tester was 10W30 Valvoline VR1. I had used Penzoil for years, since they furnished my oil for a few years ago. When the free oil ended, I felt like I owed it to them to start buying it. Tested well also. The VR1 handled more load than anything. RP was very close. They tested what I could find. Pennzoil tested well too. VR1 tested best.
I am not claiming to know everything about this. Only what friends tested for us.
Your results may vary.
