Was listening to Lake Speed Jr (general manager and head of technical support for Joe Gibbs Racing oil) on Adam Carolla's Carcast talking about oil. He is a certified lubrication specialist and oil monitoring analyst (less than 300 people in the world hold both certificates).
Very interesting. He says that Joe Gibbs oil has more zinc than Mobil 1 or any of the "over the counter" synthetics and therefore offers superior protection. The EPA emission regulations a few years back caused most manufacturers to drastically lower the amount of zinc in their oil. IE: the Mobil 1 or Havoline you're running in your car today is not the same oil as you were running a few years ago. Anyone have any experience with Joe Gibbs oil in our cars? I emailed him and he recomended their "DT 40" (5w-40).
Obviously, he works for the company but what he said made a lot of sense.
Thoughts?

oil is... such a touchy subject. If he knows his thing (being the certified lubrication specialist and oil monitoring analyst), then I would trust him. However, what is considered "superior" protection? Is it absolutely necessary for a road car?

My Lotus is not a track only car... so I need a good over the counter oil that I can buy cheaply and replace/add as necessary. However, for those who are using the car as a very competitive race car, I could understand they may need the best.

I've been using Rotella synthetic oil (for diesel cars) for my lotus and other turbo cars and haven't had a single problem. Worked great on my motorcycle too. The best thing is the availability and price :)

I've personally never used or heard of that oil.

I'm a Royal Purple fan myself, especially gear oil. Have run it in VW Baja's for years with great outcome. Heat and wear are major on air-cooled engines. Just put it in my new (used) Exige this weekend. Is it the best for a Lotus? Who knows. But I sleep at night.

It all comes down to one thing.......What does oil do? Cleans, cools and lubricates.

If whatever brand your using is doing its job your good. You can read stats and look at charts that are compressed down to a gnats ass on performance all day, everyone has their claims etc. Are you running F1?........

To me its like BBQ, yours tastes the best because you made it the way you like it. Your best buddies taste better to him than you because he made it the way he likes it. Keep your oil that way too.

I've always heard great things about Royal Purple. That and Mobil 1.

I just got 6 liters/quarts of the Gibbs Bros break in oil.

IMO having oil pressure is more important than "which oil".
Then making sure that it is not getting overheated

Where's he located? I've been looking for my dad for years. He left in the 1983 saying he was just going to go to the auto shop....and he never came back.

I run 5 gallons of a 50/50 mix of Gibbs' XP1 and XP3 in my Penkse NASCAR. Yes, gallons; it takes 2 hours to heat up using 500w probes - which must be done before starting or the bearings will be toast. Ilmor (my motor supplier) reccomended that mix or Mobil 1.

In my 9:1 compression supercharged Elise I run Royal Purple XRP 20w50 on the recommendation of the motor builder. Track only. Thankfully no external warmup required.
