## Questions & Answers

**Q: The description says pack of six.  Is that correct?**
A: Not a 6 pack.  Only 1 Quart!!!!  This is a mistake on someone's part.

**Q: i have an 08 ram that requires 4oz of limited slip additive. does this oil have ENOUGH additive blended in? how much additive is added per qt?**
A: I have an 07 f 150. I added no friction modifier a yr ago, however, noe i have chatter. Will be adding friction modifier soon. 4oz. Thats what was recommended in a Ford blog. Hope this helps.

**Q: Does this help with Hard shifting? Anyone recommend a solution for me? Someone mention Motorcraft Friction Modifier. Would that work?**
A: Some of it depends on the car. For example, I race a Miata and its not recommended to put non friction modified GL-5 grade gearbox oil in a Miata manual transmission. It's too slick and will make shifting difficult to impossible. Always use GL-4 grade oil for the manual transmission.Miata transmissions respond very nicely to the relatively expensive Ford Motorcraft MTF synthetic transmission oil with friction additives (FMFSMTF or XT-M5-QS). The ford MTF synthetic was developed for the difficult to shift Mustang gearboxes and contains special friction modifiers that allow synchromesh to work better than standard GL-4 fluid. This fluid is a lifetime replacement so it's cost is defrayed over time and the excellent shifting it provides. So depending on your car I would recommend the Motorcraft MTF. Its what I run in my race car. The Royal Purple I used in my Daily Driver BMW.Good luck.

**Q: how much oil do I need for a 2008 Ram 1500 4X4 rear differential**
A: If your rear end has LSD, then it's 4.4 pints. If your rear end doesn't have LSD, then it's 4.6 pints. To make it easy, buy three bottles of this oil and keep adding until it starts flowing from the fill hole. Don't forget the gasket.

Royal Purple is always high quality.

### ⭐⭐⭐⭐⭐ I'm a huge skeptic.
*by J***N on October 2, 2017*

I'm so used to companies flat out falsely advertising their products and promoting product features that don't do as described.. I've gotten to the point I just don't believe anything and only expect what I've already come to know from experience. Regardless, the time came to change differential fluid.. and I want nothing cheap for my Ram. I decided that, based on reviews, the least this product would do is lube as well as other gear oils. To my surprise, there really was immediate results from using. I expected nothing noticeable, but it actually did improve performance. Most people I know never even bother changing their differential fluid. For a 100 mile round trip (that I make twice a week, every week for years).. my MPG increased from an average of 14.5 to 16 on average (fluctuates with oil life, air filter and aggressiveness) to 18.6, which is actually higher than manufacturer's estimated MPG 14/18 city/highway). I gained this while driving fairly aggressively (a bit above normal), as gas mileage was the last thing on my mind to test or check. I just happened to notice after the trip while checking diagnostic logs for other things. The gain was just significant enough that it was undoubtedly the fluid change affecting it. Too many things affect torque and horsepower for me to have solid statistics from comparison, but as a "first time" Royal Purple user, the results that have been noticeable has made me more optimistic towards effects less noticeable or not noticeable at all.. such as advanced conditioning and wear reduction.. effects that would take much more time to observe. Because of my experience, I will now be ditching Mopar and replacing various fluids throughout my vehicle with Royal Purple. I don't recommend for others to make decisions based on my review, though. I suggest trying the product out next oil change and make decisions based on first hand experience.
