Good price, not the best, but I love doing my business with Amazon and its merchants. When it comes to oil everyone has their favorite, Royal Purple is tried and true, it has yet to let me down. Will buy again, also it came well packaged and in air tight bags.

I use Royal Purple in my 2002 Ford F150 and my 2008 Dodge Charger. It keeps my engine clean and helps to add a little more horse power under the hood.

Started to use this and noticed difference already. It's definitely a better price here. The oil can run up to 6000k or 8k and that's less expense for oil changes in the long run. Pair with royal purple filter and you're good to go.

Bought it from my local store, improved my Mpg 4 miles per gal. Haven't noticed much of a power difference it's a V8 runs nice and smooth as advertised. Plan on changing my other fluids to keep my car running perfect! Awesome stuff.

Big difference when I put it in my 03 Ford Mustang GT. This is the only stuff I put in it. Will buy again

I like ordering from Amazon. Royal Purple is the best oil for getting more gas mileage out of your vehicle.

I've used a lot of oil. This one works.

How does an oil not work? Check out [...]

There are several brands of full synthetic "boutique" oils. This is one of them. I also like Lucas Oil & Amsoil. In a pinch, I'll also use Mobil 1. I'm no expert. But I do change my oil regularly & my cars tend to last a really long time. One of them has almost 300,000 miles on a Ford 5.0 engine. And if anyone knows anything about cars with a big V8; then you know that you can't help yourself when it comes to driving at WOT. If you plan on keeping your cars, then this may be worth the investment. If you trade in your cars every few years, then don't do anything except for trading it back in.

Synerlec, Royal Purple's proprietary, additive lubricant technology, is the cornerstone of RP's entire product line. It creates an ionic bond that adheres to metal parts to provide continuous protection even at start-up and strengthens the oil to provide unparalleled performance and protection.

Royal Purple's high film strength prevents contact between metal parts and improves sealing inside the engine for more complete combustion and dramatically reduced wear. Improved combustion creates more power, better fuel economy and reduced emissions.

Royal Purple remains on the metal surface long after ordinary lubricants would have been squeezed out by pressure and heat. It actually improves engine surfaces by responding to increased pressure with increased viscosity until the metal peaks (asperities) undergo deformation and flow into the low spots. Over time, the metal surface becomes extremely smooth and can even develop a mirror-like surface.

I've always been told that Royal Purple products were good, but more expensive than the products I've used in the past. However, Amazon offered a package at a price that was actually cheaper than if I bought it at a local store, plus they shipped it for free. As for the product, since I tend to use quality synthetic oils in my 2008 Honda Civic I guess only time will tell, but I do seem to have more pickup that has a firmer feel. My Honda is slightly modified, but the other day I out ran a BMW that was attempting to cut me off as I merged onto the free way. Was it the oil? I don't know, but as long as I maintain my average of 35 MPG and can merge at that pace I will continue to buy Royal Purple. It should be noted that I also use ZMax at the same time, or when I can afford it.
