No let me start out by saying I'm a car enthusiast by heart, I build cars to have not only drive back and forth to work but to take to the track on the weekends. Most of my life of cars I've become quite familiar and partial to 350 Chevy Small Blocks, Chevy LSX's, and 4.6L 36V Dual Cam Fords. I've run super chargers (top mount, twin screw, and centrifugal) along with my fair share of Turbo Chargers.
I've more recently become such of a fan of European and Imports due to high revving 4-cylinders that not only make smart power but produce good daily drive-able characteristics (including great gas mileage). My current vehicle that I daily and track is my Lotus Elise, it uses a Toyota sourced 1.8L 2ZZ-GE (same as the Celica GT) which is high strung, high revving motor. Most important factor to a motor that constantly sees revs up to 8700rpm daily is excellent lubrication to fight friction along with heat. I can say as always with my past motors Royal Purple lives up to the hype with it's excellent Synerlec additive that helps coat and protect engine components at load, speed, and high temps. From all my engines I've pulled down valve covers and intakes I can attest to the claims, all my cams, rollers, and bearing always look smooth and clean (no noticeable wear I can pick with my finger nail).
They may not list all the bogus standards that mean absolutely nothing when it comes down to it (think about all the marketing standards on what constitutes synthetic blend?) they get everything right with there formula. Since acquiring this car and changing to Royal Purple at 36,000 miles I've noticed over the past 20,000 miles that the motor has become more responsive and smoother through the rpms. I noticed my track buddy with his Lotus Exige (supercharged) commented on how smooth and responsive the motor felt when he drove a few laps in my car, he was surprised for a stock N/A motor with over 50,000 miles! I made a believer out of him that day!
Good reading material to help those who can't fathom the missing bogus standards

I drive 160+ miles a day at speeds 65-85mph. Royal purple 5w-40 has a very thick oil film and provides excellent miles per gallon. My engine runs very smooth at high rpm and very quiet at highway speeds. Thank You

I have tried a lot of different oils in my life time but ROYAL PURPLE is the BEST. I have been using the oil for 2 years now . It is a little expensive, but you get what you pay for. I look at it this way pay a little more for the oil or pay a lot when you have to repair the engine. My car has never run better. All their products are the best you can buy.
Honest reviews on Royal Purple 01540 API-Licensed SAE 5W-40 High Performance
This is an area that I am very familiar with as I previously distributed synthetic oil. During this period I befriended one of the leading scientists who created and formulated synthetic oils. We spent a lot of time together and I often accompanied him to several industry seminars. I received quite an education about oil.
Briefly synthetic oil does everything your regular motor does, only it does it better. Plus Royal Purple uses a different base stock (ester) then regular and most other synthetic oils--it clings naturally to metal. thus reducing dry starts (a leading cause of engine wear), reduces friction; has a higher film strength; reaches operating temperature quicker; runs cooler and has a greater resistance to high temperature breakdown;has a high solvency action that will clean the inside of your engine; it has a lower freezing point point, ie. it will not thicken up in the coldest of climates, and finally it will increase your HP and mpg. In my opinion Royal Purple is the best synthetic oil on the market today.
Is there a downside? Yes it is expensive and hard on valve seals. If you have an older car with a lot of miles on it (about 60,000 or more) the seals and rings may be filled up with engine deposits and the oil may flush them out,leaving you with an oil burner. We had this problem on my friends Saturn. The oil made a big difference in performance and mpg, but it began to burn oil. So on the next change we dumped it and replaced it with Mobil ! and Lucas Synthetic Oil Stabilizer and the oil consumption ceased. It was a better performance then regular oil but not as good as the Royal Purple. Also suggest you use Royal Purple transmission oil, it does make a difference.

I don't see any specs that it meets VW/Audi 502 505? Many Syn do, why isn't this published, and why so expensive, claims it's superior, but doesn't even have specs like other cheap SYN, is this all BS? No specs, no good. simple.
