Royal Purple11485 API-Licensed SAE 0W-40 High Performance Synthetic Motor Oil - 12 Quart

So far a very good oil that I only can find in stock on Amazon.

I've been running/using Royal Purple lubricants in all my vehicles for over 10yrs now (might even be close to 20yrs) and don't plan on changing anytime soon. First chance I got after having purchased my vehicles, I switch the oil/lube in all components (i.e. engine, trans, diff, transfer case, etc.) over to Royal Purple products. I don't do it immediately of course, when the time comes for changing the oil and/or lubricant that's when I switch over. All my cars have responded well to the Royal Purple products and I've noticed slight changes in vehicle's behavior (i.e. runs smoother, runs cooler, etc.). Also, if you pay attention to your car, you can notice when its time to change the engine oil (performance degradation, mpg degradation, runs slightly hotter, etc.). I've noticed that I can run longer/more distance with Royal Purple than other oils and/or the oils/lubes they came with. A lot of people have their personal opinions and some don't even think oil matters much, and if you are on top of being consistent with preventative maintenance and don't "abuse" your vehicle much then it might not. However, if you're the type that sometimes forgets about your maintenance schedule or doesn't care for it or likes to drive the s*** out of your car (but not overdoing it of course) I would recommend considering the Royal Purple products.

The media could not be loaded. Royal Purple has always been a good lubricant for me. I started using their 0W40 after reading a comparison with the Mobil1. Apparently, the same specs but this is a bit cheaper. I use it on a Ford 460 cu.in. crate motor installed in a Superformance Cobra. When I was using 10W40, I used to change the oil in the fall for winter storage, then again in the Spring before the season started.. Now I just do fresh oil before winter storage and just use the same oil for the warmer seasons. Good oil and economics since I have a custom 8 quart oil pan and it gets expensive! I recommend this oil for regular driving but not for racing.

Great product

Bought this for my Honda VTX1300 oil change. I know it's not exact spec of what is called for, but the larger temperature range helps alot here when temps vary by 50 degrees sometimes through the day. Works great, I've had it in my bike now for a couple months. Almost time to change again!

This is really good for high-end engines, especially those with turbos. No questions asked, I will get this every time for my Porsche and Audis.

It adds power to your vehicle as soon as you replaced your oil with it. I have never seen that before in any oils out there

Love this oil

Very nice product & fast shipping, Thank you
