Question & Answers with Mark Cronquist
Head Engine Builder for Joe Gibbs Racing

Mark Cronquist
Head Engine Builder
Joe Gibbs Racing

Why would Mark Cronquist, a NASCAR Nextel Cup Championship winning engine builder, put his name on this product? Because he made the decision to find an oil that could stand up to the performance demands of a 500 to 600 mile race where an 800 plus horsepower engine sees over 9,500 rpm and 240 degree temperatures. When we couldn't find it, we made it.

Q: Do you really use this oil, or is this just some marketing deal?
A: We currently use this exact oil in all of our engines. In fact, we've been using our own blend of racing oil since 1999.

Q: Why would Joe Gibbs Racing buy oil when you could get it for free from a major oil company?
A: We were not pleased with the quality of true racing oils that were available. We were seeing wear in the valvetrain that kept us from being as aggressive as we wanted to be. Instead of working around the oil, we decided to make a change, so we found a world leader in lubrication technology that could provide a custom blend of synthetic oils to meet our extreme needs. The old adage that you get what you pay for applies when it comes to racing oils. True racing oils require special additives that cost too much to give away.

Q: What makes Joe Gibbs Racing Oil special?
A: The additive package and blend of synthetic base oils that comprise Joe Gibbs Racing Oil can not be found in any street legal or API certified oil. In fact, no other racing oil matches the unique formulation of Joe Gibbs Racing Oil. Once we began using Joe Gibbs Racing Oil, our wear problems went away, and we were able to be more aggressive with our valvetrain. Over the last four seasons we've been able to make the formula better, and as a result, we can make more power without compromising engine durability because of Joe Gibbs Racing Oil.

Q: Aren't other racing oils just as good?
A: No, we've tested our racing oil against the top racing and qualifying oils on the market, and our testing has showed that Joe Gibbs Racing Oil provides an un-matched combination of pour-in power and engine durability. No other racing oil can provide 600 miles of protection at temperatures above 220 degrees while providing qualifying oil like power increases. Joe Gibbs racing oil provides power without compromise. We looked for an oil like this, but we couldn't buy it anywhere. So, we had it made, and now you can get it.

Q: Why do you only have the one racing oil?
A: We only use one racing oil for all of our engines. We qualify and race on the same oil on both open and restrictor plate engines. We do use a special petroleum based break in oil to break in all of our engines. These are the only two products we use, so that is why we are only offering those products. If we don't use it, we won't offer it.
