I have been using Royal Purple for a number of years. I changed to Mobil 1 because Walmart didn't carry RP. The difference was great; Mobil 1 seem to be sluggish even though it was synthetic. Royal Purple is clean, even after 5000 mi! If you want your car to last, use Royal Purple!

I have tried a few of the other synthetic oils and Royal Purple is the only oil to last longer than the manufactures suggests to change it. When it comes to changing time it almost looks like it did when I first put in the car. I own a 2012 Kia Sorento and would use no other oil in my car.

I have been using this product for over a year now and have nothing but good things to say about this product. I am an expeditor and drive 80,000+ miles/yr and run 10K intervals on my changes. This is by far the best oil on the market for your money. I used to use Valvoline Synpower until I found a store closing this oil out. I bought the majority of it to give it a try. I followed the recommendation of doing 2-3k mi changes upon switching then after the 2nd change beginning the 10-12k intervals. This stuff is awesome! When I was unable to get this, I tried Mobil, Pennzoil, Valvoline, Castrol, AMSOIL and Quaker State synthetics (all 5w-30) and none of them compare to the RP. My van runs smoother, the fuel economy is up by 1-1 1/2 mpg (which is a BIG deal for a 2500HD with a 6L V-8 in it), and being able to run 10K between changes saves me allot of $ in maintenance costs. It also saved my engine from severe damage when I had a blown head gasket which I drove 60K mi on before ultimately diagnosing it. RP has since reformulated the line up to include an API approved oil for vehicles under warranty. I use the HPS (High Performance Street) version now for the added ZDDP (zinc/phosphorus) package it has. But it is NOT recommended for vehicles under warranty. The API version has less of this additive to protect emission system components and meet the new industry standards (ILSAC GF-5 & Dexos 1 notably). Either way this oil is the best money can buy. I now run all their products in my vehicle and the driveline is buttery smooth and well protected from the consistent 2500# loads I carry. I highly recommend trying RP over the other choices available and experience why this is the oil to run.
