Durability advantage

A quality lubricant, such as Duralec Super, protects against cylinder liner & piston ring wear ensuring compression maintenance, engine power, and vehicle efficiency.

Poor scuffing protection leads to adhesive wear on cylinder liners and rings. This results in blowby, loss of compression, power loss and increased fuel consumption.

    I have used this product for several years now and am very pleased with it’s performance. I had been using another high quality synthetic motor oil for a long time and while it worked well Royal Purple exceeds it. With Royal Purple the diesel engine in my 2001 Ford runs quieter and usage is practically zero. What got me to first try Royal Purple was the price from Walmart but I’m sold on it now no matter the price. I’m just now switching over to their Max Tane injector cleaner.

    Great selection for your rig and ships with ease!

    If you own a diesel, and know that maintenance is the #1 key to having them last, then don’t mess around with cheap stuff. ROYAL PURPLE is the best for a reason, and thus close to same costs of other diesel oils but better. I’ve used Royal Purple in all my vehicles for years and when my last Yukon started to act up, pulling the bottom apart was amazed at how clean the entire bottom of the motor was. You can never go wrong with the Purple stuff

    A quality product. A full synthetic 15-40 W engine oil. Love the order online pickup in store option. Makes it easy to find while on the road.

    I use Royal Purple Duralec 15W40 because that’s what my boat mechanic recommended. I order through Summit Racing because the service is incredible. First of all it is an easy web-site to negotiate. The prices are competitive, fast shipping and delivery and the one time I had a question it was answered promptly. Any interaction I have had with Summit racing has been professional and I plan on continuing doing business with them.

    Everyone knows royal purple’s reputation for great products. I have used their oil in my diesel engine for ultimate engine wear protection. Pricey but so is another engine. This will help your engine last longer with fewer oil changes.

    This oil i recommend to all my family members and friends

  • 5star

    Great product. Highly recommended. Using it on my Kubota L47 Tractor
