This may be a dumb question, but Imma ask it anyways. What exactly is the difference between say Valvoline racing oil and say the Wal-Mart super tech stuff (both being 20-50)besides two and a half times the cost? We run the Valvoline and change it every other race....which would be 40-45 racing laps for us. Do we really need the "better" stuff?

The valvoline racing oil is formulated for racing and extreme use. It's not the same as valvoline all climate 20w50 which is more for street use. You might be alright running a normal(not racing oil) 20w50 but I would take a look at your engine cost. An extra 1$ a quart can be cheap insurance or peace of mind when you are talking a thousand or several thousand dollars in engine costs.

If you're running Valvoline racing oil and changing it every 40 laps, you're throwing away alot of good oil. It should be able to make at least 3 or 4 races unless it's really getting fried, or no airfilter, no oil filter etc etc.

Use Mobil 1. Save ten times the money and headaches in the long run.. I use to run that 70 wt kendall racing and you wouldn't believe the HP you lose on a normal stock pan type engine. Runs alot warmer as well. Mobil 1 drops oil temps 20-30 degrees over conventional 50wt motor oil.

i switched from valvoline racing to royal purple. saved me about 100$ last year because i can run the royal purple 10-12 nights before it starts to turn brownish. i was switching the valvoline every other night.

Raz.....believe it or not, we run both a air filter and a oil filter. No wonder the car is front heavy. And you are right the oil looks as good coming out of the pan as it does coming out of the bottle after 40 laps. We will have to see what it looks like after 80 once maybe. Julia....what makes the Mobile 1 run that much cooler?
