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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality Gear Oil *by N***S on March 14, 2026* Used as the heavy duty option for my 20’ Jeep Gladiator.
